Thats right...
We have just broken RAT history again and have exceeded our expectations on the very first pull from a recently developed 2056 combo using a cam that was developed in 2006 and a set of off the shelf LE 200 heads!



This engine was originally going to be equipped with our roller lifters, but due to continued challenges we had to scratch the rollers and apply conventional lifters to the engine. The power we have made with this engine using the conventional lifters is basically the same or just a tad more than we were looking for with the rollers, so I am VERY happy.

The graph posted below is from the engine's VERY FIRST pull and we know this combo has more potential that will be found in tuning alone as we continue to understand how the combination functions.

Now, the most amazing part of this is the fact that this engine absolutely annihilates the best 2270 combos from 2-3 years ago in every way! It makes just as much torque, and more HP that our 9:1 Performer 2270 did in 2006!

Last week Charles from LN engineering came down for another round of oil testing and we used this engine for the analysis. After testing 11 oils we decided to pull the heads back off the engine to see if Len can find even more power. We'll have the heads back this week and will get more results.

I honestly expect 190 HP from this engine with the changes Len will make and the CR we plan on adding. At 9:1 this engine would run easily on 89 octane and based on the timing settings the engine liked it will love 9.5-9.8:1 CR

You can view a short video we threw together from the oil testing on youtube here
http://www.youtube.com/watch?v=FYV8OD8Ohlg&feature=user

This one is just days away from being added to my turn key engine catalog... This may be the best cost/HP engine we have ever created and it still has great torque!

Posted by: Jake Raby Jan 28 2008, 08:44 AM

OOps! Wrong graph got posted somehow!! That first graph is the typical power we see from a 2056.. Here is the one I should have posted. Sorry about that!

Posted by: rhodyguy Jan 28 2008, 09:01 AM

wow agin!! 44s with 32 vents, tall mainfolds and a mallory?

Posted by: Jake Raby Jan 28 2008, 09:04 AM

Nope, off the shelf 45 Dellortos and tall manifolds..

The short manifolds will more than likely give us too much top end and sacrifice torque. I want to retain this torque or capitalize on it!!

Posted by: Bleyseng Jan 28 2008, 09:06 AM

How would this combo do with the twin TB'S?

Posted by: Trevorg7 Jan 28 2008, 09:07 AM

Very cool!

Congrats

Posted by: Jake Raby Jan 28 2008, 09:20 AM

This cam has carburetor characteristics.. More than likely FI would HURT this combo's power..

Posted by: rhodyguy Jan 28 2008, 09:21 AM

i'm Del ingnant. how do the 45s compare to a set 44s configed as i mentioned? my guess is a tangerine is bolted up. if you were ever so inclined, i'd find it interesting to see a test for those that don't have the scratch for one of chris' systems and run 2.0 ss hes and a performance exhaust, or a powerplant designed for them.

I second this motion.

Posted by: Jake Raby Jan 28 2008, 10:30 AM

This engine would not be supported by Heat exchangers. The cam it uses is heavy on exhaust duration and requires an exhaust like Chris'

The 44 Weber flows 290 CFM Vs the 45 dell's 330 CFM, but a 44 weber should support the engine with ease. I'll know when I get the heads back on it with more CR and we go for round 2.

Jake, the end of that video cracked me up. you are having way too much fun being the engine DR/mad scientist. I bet you like the smell of brad penn. I know I do. few are fortunate enough to enjoy their job as much as us.

PS. that would make a kick butt CP engine to run in PCS AX. I think it would be no contest against a regular 2.0 carbd engine

will this technology tranfer to your stroker mojos to increase their output also?

Posted by: r_towle Jan 28 2008, 12:03 PM

So, based upon those results, what would the 2270 do with a similar cam/head combo?

Rich

Posted by: Jake Raby Jan 28 2008, 12:20 PM

Yep.. I do have a lot of fun... The scent of Brad Penn can be noted from the tailpipe 100 feet away!!


No way, it has almost 100HP more than stock, not bad from less than 100ccs of added displacement!!


Development with this will occur soon.. BUT there is a compromise of this cam being ran with stroke.. Thats because the lovbe lift is hefty and requires a seriously reduced base circle. the reduced B/C pulls the lifters further from their bores when on the heel of the lobe and that weakens the bores and makes for more wear...

This is why I always preach that it's all in the combo, because a 2270 with this cam may make big power, but wouldn't meet my demands for longevity for the MassIVe program.

That being said I'll almost bet that this cam, when used in a 2270 will make LESS power than with the 2056 and thats because bigger simply isn't better than "smarter"...


I'll let the engine tell me.. Give me 45 days.

Posted by: r_towle Jan 28 2008, 12:22 PM

I figured you just found some new magic and you would try it on your favorite motor...just curious if you had already done it.

Jake,
I have to tell you, I sometimes think you are a little heavy handed in your posts but that video is great!!! It was informative, entertaining and funny. I've gained a whole new respect for you. Your personality doesn't come through in your posts in any way close to the way it does in that video.
Keep up the good work! I'm anxious to see the results of this test, where can they be found?

I learned long ago that people only allow things to sink in here on the forums if it is bold and firm...

The video is really who I am.. You'll be seeing many, many more videos in the coming months....

Posted by: r_towle Jan 28 2008, 02:09 PM

Interesting point.
I noticed in one of the first TV commercials for Obama that he had an aweful time looking at the camera. He kept reading the Q card and the result was he looked shifty eyed.
I sent an email to his keepers to point that out.
I was not the only one who noticed this...he no longer does one on one with the camera, he stopped that format all together.

Point being is that we each have our own style that works best when marketing and maybe the videos are better, who knows.

Rich

Posted by: Jake Raby Jan 28 2008, 02:18 PM

I am not trying to market.

Its more of an education thing.. When people understand what they are working on they will be much more inclined to manipulate it with less intimidation.

Posted by: flippa Jan 28 2008, 02:50 PM

Great work. I love reading these posts; always something to learn. Thanks for taking the time to share your knowledge!!! To say you were passionate about your research & development would be a huge understatement!

Love the other video taken in the 3.0 bug. My 70 never ran quite like that!

Posted by: ConeDodger Jan 28 2008, 02:56 PM

OMG!!! I laughed my head off... "have a milk jug of oil... It's great for the heart!" That is hysterical!

My only problem with you and Charles getting together and testing oil is that I go out and buy a case or two of oil and it winds up on the shelf because you moved on to a new favorite. I now have a case of Royal Purple that was going to be my post-break in oil sitting on the shelf and a new case of Brad Penn. Then, like I said on your forum, some woman from PCA SVR who is a Swepco dealer was raving this last weekend that Swepco beat them all! Ahhhh! I am going crazy.

But it's ok Jake, I am going to sit down and sip from my milk jug of oil...

Posted by: Jake Raby Jan 28 2008, 03:07 PM

Brad Penn is still my favorite and after this engine goes back together for the final round we'll test a few of them again since I should be able to turn it up another 800 RPM- that may change everything.

Glad you guys like the video, I didn't have any of that stuff planned, it was spur of the moment off the cuff to say the least..

The Swepco is promising, but it'll take more than this one test to prove that..

And anyone whi is willing to give to the oil R/D fund feel free, this shit is expensive and time consuming and no one gives it to us...

really, congrats. those curves look great!

Posted by: 356 Jan 28 2008, 07:16 PM

Good for you....

But just once, I'd like to hear about a dyno run, a build sheet and a PRICE?

Is it too much to ask? Joe Blow asked for "X", he got this with "X combo" and he paid this much, I'm not asking for trade secrets......I've asked for a price a few times in the past and have since given up.

I'd love to do a T4 conversion to a 356 but would like to know my costs up front.....with all your experimenting...a firm price on a turn key 2000-2200cc motor should be not a problem.....right?

Posted by: Jake Raby Jan 28 2008, 07:49 PM

A build sheet is a trade secret as far as we are concerned. I can share some info in phone conversations, but do not do much here on the net since our stuff was ripped off in 2004.


That info is personal between the customer and myself. I don't post the prices for individual customers engines because its not fair to them.


Have you ever scheduled a phone chat with me?? This the ONLY way to get an accurate, to the dollar or even ballpark price. There are HUGE variables with pricing an engine like this and those must be considered when pricing the combination.


Thats no problem, if I receive the info I need and can ask you the right questions to be able to get the price added up. In fact I can get the price within 500 bucks in our first phone chat, the proposal we do up front locks the price to the dollar and that won't change once the project is engaged.


Yes, but I have a strict set of guidelines for attaining these prices, you can go to my www.type4store.com site and select the "turnkey engines" selection to see some samples of costs for the most general engines.

But reading through the order process on my site and starting the process as I have outlined makes for a progressive transaction and makes my system work very well. I offer phone chats by appointment each Wednesday evening and have slots open this week, so if you'd like a price just start the process.

Posted by: 356 Jan 28 2008, 08:05 PM

Lately? No...I've been busy doing other projects but now I'm back and would like to know how much.....

In the past, yes, I have asked. I was unable to get a simple "it will cost somewhere around this price not to exceed this price....."

I'm NOT gonna get in a war here, it's a simple knock on your otherwise stellar work...at least based on your postings.

I've yet to have anyone that "I" know run one of your motors or get an idea on what one will cost.....AND No one wants to admit to what they shelled out....

Usually when one advertises a product...they end up with a price....simply an observation.

Posted by: Jake Raby Jan 28 2008, 09:28 PM

OK


Like I said, I only give this info out via phone after a question/ answer session. In the past when I made general quotes I was held to them, even for engines that were more intensive than they were quoted. There are simply too many variables and the range can be as much as 3-4K for the same engine displacement!

.
OK.. My intensity goes into development- not sales.


Like I said, the Type4Store has the closest estimates you can get for an engine without a phone chat with me.


And most products aren't as variable as a custom engine. There are literally 40+ items that can impact the cost of an engine from core charges to our coating service, cryo, EFI, 3 different levels of heads and other options.

Other builders keep it simple and just don't offer these items that create variables.. The result is a more generic combo-

Now, I didn't make this post as an advertisement. I made it to illustrate how far we have come with development and the pride that comes with that means MORE to me than any amount of money generated by the efforts.

When I can make 170HP with an engine less than 100ccs larger than a bone stock 2.0 I don't have to make a dime the rest of the month to be happy as hell!

That said, if you want a price the steps are plainly posted on my site, hundreds of people per year consult with me and get their prices, its not difficult and IS VERY effective in seeing if we are compatible enough for a transaction and at the end of the first chat you WILL have a net price accurate within 500 bucks of the actual net cost.

Posted by: yarin Jan 28 2008, 09:31 PM

WOW, very impressive numbers.

Jake - will this be available in kit form? or just turn-key?

Posted by: 356 Jan 28 2008, 09:37 PM

Well then, you won't get an order from me. I have seen posts about deposits being made and then the buyer going WTF???? later when the final bill came due and then bailing out....

I've been around long enough and I'm not afraid of sticker shock....I've even bought a Harry (The Maestro) Pellow motor back when he was alive. He wasn't cheap but I got an answer when I asked how much. Same with FAT in CA when I was back in High School and a few other Type I builders.

I've also seen AND met the other, darker side of the business....Mark Stephens.....yer buddy Stromberg...and more than a few others....

Again...just my observation and not a knock on the final product you sell. If Navarro is involved it's a gotta be quality product.....but I wants to know up front what the bill is.

Posted by: Jake Raby Jan 28 2008, 10:04 PM

You are not being fair...

The instance you speak of was ONE out of more than a thousand transactions..

The guy who flaked out had wanted EVERY bell and whistle imaginable, but blew his money on other things before we got to the proposal.. That wasn't my fault, but he felt that he could convince others that it was- he didn't.

That wasn't the bill that he bailed on, it was the PROPOSAL price, the price that would have been EXACTLY what was due in the end.

When that instance occurred I made immediate changes to my program that would prevent it from occurring again, that was 3 years ago and it hasn't happened since and never will again.

Those on the dark side don't have ordering procedures and have zero organization because they are fly by night, shoestring budget con artists. Thats far from how I have gained my position in this industry and thats why what I create isn't mass produced or cheap...

Yet again, you have not followed my procedures to get a price and I won't break these procedures for anyone, for any reason. Its part of the way I screen those who want my work, because there is NOTHING worse than incompatible parties engaging in a transaction this in depth..

Everything here has a procedure including the transactions right down to the crating of an engine.

I'll close by saying that I don't make public announcements of price for many reasons, the least of which is sticker shock. I don't want to make one person a price and the next 6 weeks be filed with "you told XXX that it would cost XXX, why is mine more???" That increases my time in the damn office and thats the place I don't want to be...

No information is much better than misinformation.

Posted by: Jake Raby Jan 28 2008, 10:10 PM

My kits are set in stone through 2009...

This engine will be re-developed time and time again until then and if the wear and effectiveness are where I demand them we'll think about making it a kit..

No kits will be added to the program till 2010, no matter how effective they are in the lab.... After the latest re-vamp of the kit program I don't want to think about it for two years!!

This is a turn key offering, but I need more development and test time with it first, like a trip cross country...

Posted by: McMark Jan 28 2008, 10:47 PM

Mike, if you want a price, make a phone call. Seems pretty straightforward to me...

Posted by: Elliot Cannon Jan 28 2008, 11:05 PM

What will be the minimum octane for this engine? Wll those of us in Calilfornia need to add an octane booster?

Cheers, Elliot

Posted by: JRust Jan 29 2008, 12:50 AM

It does sound pretty simple. Call him & he will get you your price. Try doing a search. There are a growing number who have bought a Raby motor. Both the kit & the turn key. I've heard good things & I'm hardly on here

Keep up the great work Jake. Many of us do appreciatte it & have a future Raby motor in mind. We hope to see you this year at the WCC in Seattle. I've got a 2.4 big4 I bought I hope to have in & going. Not your build but will hopefully hold me over till I can convince the wife

Posted by: 356 Jan 29 2008, 06:24 AM

Simply an observation on my part. Don't shoot the messenger.

Posted by: rhodyguy Jan 29 2008, 06:39 AM

i'll tell you one reason why a hard price isn't posted. when jake takes the time to speak with you on the phone and you have his site up you (YOU, not jake pushing) start with "the while in in there". maybe opt for a balance upgrade. "gee, a midlevel (or better) rod upgrade would be nice". YOU need to have a pretty good of what YOU want! do you need the upright shroud for your 356? do you have a known set of carbs or some unknown set that has been sitting on a shelve for years? single item pricing is spelled out at the T-4 store. mark's 2056 engines start at $5k. figure it out.

if you're serious about purchasing a kit or turn key, contact jake. make an appointment to speak with him. tell him what you want. you'll get the firm pricing on the engine you intend to buy. it's pretty simple.

Posted by: Jake Raby Jan 29 2008, 06:54 AM

As far as octane for this combo, we ran it premium pump gas.. BUT the tuning it wanted told me that it would easily run on mid grade @ 9:1..

We are now taking the CR to 9.8:1 and adding some quench to the heads and will still run it on premium, but I expect big things from the bump in CR and other mods that Len is doing to the heads..

Posted by: ConeDodger Jan 29 2008, 11:27 AM

Jake,
I realize this is a test engine. How would you feel about letting an engine you built out the door for street use with 9.8:1 Compression? With Nickies it should be good correct? But what about cast iron?

Posted by: Jake Raby Jan 29 2008, 11:30 AM

That CR isn't high dynamically with this cam..

In fact this cam will give the same dynamic CR at 9.8:1 as your 2270 kit has at 9:1

Thats why I am raising the CR, it will positively impact the tuning, powerband and efficiency of the combo..

Thats my hypothesis.

Posted by: ChrisNPDrider Jan 29 2008, 11:56 AM

Way to go Jake! Le200 heads all the way!
With all the data you get, is it possible to report "efficiency" of one of your engine pulls in terms of MPG using a standard car, say 2000lbs, 0.32 cd, standard flywheel and running gear? Small(ish) displacement with great matched flow and high compression should get great MPG.

Posted by: Jake Raby Jan 29 2008, 12:18 PM

We can't calculate MPG on the dyno because aerodynamics, drag and gearing all impact it..

BUT BSFC values that show the most efficiency SHOULD equate to the best MPG..

The 170 HP engine posted here ran ALL DAY with 24 pulls to 6,500 RPM on 4.5 gallons of gas. I am SURE that in my test car this beat will get 30-32 MPG.

Posted by: Brett W Jan 29 2008, 04:21 PM

I'm glad you finally made the mark with a 2056. I always felt that engine should make at least that.

Posted by: Jake Raby Jan 29 2008, 04:58 PM

Len finished the Gen3 head upgrades and gave us a tad more CR today.. I'll have it back on the dyno tomorrow for the next round..
I'll take more video too :-)

Posted by: Thomas J Bliznik Jan 29 2008, 06:24 PM

Hi Jake,

I know this is a little off subject on this post, but I just looked at your new web site aircooledtechnology.com showing all the new cylinder heads. The site rocks. I am sooo excited & waiting for my new LE-180 Cylinder Heads to arrive. If they haven't shipped would you please review my order in case I forgot to order something along with the #9550 cam & valve train kit already received. I know I forgot to order the rear seal #8 and spark plugs. If you haven't shipped the heads add these small items I forgot to my invoice.

Thanks Jake,

BTW, guys,
My almost stock 2.0 liter D-Jet with counterweighted crank, lightened flywheel, euro pistons with Jake's #9550 cam valve train upgrade kit with the new LE-180 heads should give me a sweet running motor. I will also be running Brad Penn oil from Jake. Hey guys, check out Jakes web site.

Posted by: Jake Raby Jan 29 2008, 08:37 PM

Actually we reloaded the old site that was created in 1997... e changed the content and updated it, but thats the oldest template of the site we had..

Seems that people like it more than any other version and it is easier to navigate.. I am working on it tonight..

When I have the heads in hand I'll call you to summarize the order, you can add whatever you want then :-)

Posted by: HAM Inc Jan 30 2008, 08:29 AM

I continue to be amazed at the power that is being unleashed from these engines. The LE series heads have given us a solid, consistent platform on which to build. The power #'s Jake is getting on pump gas now used to be reserved for higher compression engines on race gas.

Good work, Dude!

Posted by: Rob Ways Jan 30 2008, 08:52 AM

Agreed.

All this is giving us a lot to dream about....

What is the max HP a 2056 can get out of a full "kit" and still use the stock FI?

Posted by: grantsfo Jan 30 2008, 10:15 AM

I use Swepco based on input from well known engine builder in the SF Bay Area. I abuse my aircooled motor running between 5000 RPM to 7500 RPM on the track for 25 minute sessions 5 or six times a day - 10 times a year. Went a full season with no issues, my motor runs cooler with Swepco as well. I get Swepco a lot cheaper than I can get Brad Penn, Royal Purple etc as well.

Keep on testing Swepco as I think its a fine choice.

Yeah Jake youre all about education! You eat, drink and poop self promotion. LOL! Nothing wrong with that but dont wrap it in this educational BS.

Posted by: Jake Raby Jan 30 2008, 10:25 AM

Thats been developed for years.. I finally made a purpose built kit for it, the 2056-115 meaning 115 HP.. Thats it safely.

Here are it's details in presentation format
http://www.rdtlabs.com/Presentations/por2056kit.htm

Keeping the stock FI KILLS my ability to manipulate the engine as far as we'd like safely.

Len did a speedy tur around on the heads for this 170 HP beast and it's going back together in dyno cell 1 right now, will be ready for another round this afternoon..

In dyno cell 2 I have our FP production engine.. It's fired up and getting warm for work right now..

Videos from the "dueling dynos" will be ready in a couple of days.. My neighbors really won't like this, just one engine can be heard SIX MILES away....

I think its passion more than promotion. fortunate and few are those who play with our toys and earn a living at it. while the masses dred Mondays, guys like Jake blaze through a weekend at the shop and don't even notice its Sunday. self promotion is the unintentional byproduct of his willingness to share his results. I know a salesman when I see one and he is not a salesman

Posted by: Bleyseng Jan 30 2008, 08:24 PM

What exactly has been your tuning problems with Djet???

Posted by: grantsfo Jan 30 2008, 10:06 PM

Ten track events with five to six 25 minute sessions. Thats 2 hours of full out driving each event. 20 hours of full out track driving annually. Then I do 10 to 12 AX events but I really dont see AX evets as anything that stress the motor so I dont count them.

Posted by: sean_v8_914 Jan 30 2008, 11:00 PM

not compared to the track time. ax doesnt even get the oil hot. I thought you only did the track stuff. with 10 AX in the track mix, I would say you get your fill

Posted by: Duffster Jan 30 2008, 11:19 PM

Jeeez.... Jake Raby and Z together in the same astral plane... I sense a disturbance in the Force!

Posted by: Jake Raby Jan 31 2008, 10:14 AM

OK here are the numbers before and after the head/ CR changes


I have posted the original graph as well for comparison. We re-tested using the exact same oil and the weather is spot on within 1% net from last weeks testing- the jetting and timing remain the same as well.


This is what we expected from a drop in deck height, added quench and only .5 digit more CR taking us to 9.45:1. The engine is more responsive and the peak torque was moved down and broadened dramatically with the added CR and port changes that Len did.

This is how we continually capitalize on my combos time and time again. Thanks to len for getting the heads turned around so quickly so I could re-test without ever unbolting it off the dyno!

This chapter is done.... We learned a lot and hope you did too!

Posted by: Phoenix914 Jan 31 2008, 10:18 AM

Please don't forget the promised video! Wish my job was that much fun.

Posted by: HAM Inc Jan 31 2008, 10:43 AM

Glad to help, Jake. I love getting feedback on our developments.

I think this clearly illustrates the importance of designing a combo with minimum deck whenever possible. On some street combos it is not affordable to configure for exactly .040 deck. But for competition it is clear the deck is critical to max performance.

That is one ass kicking 2056!

Posted by: Jake Raby Jan 31 2008, 11:04 AM

I videoed our production engine instead... It's much more impressive to hear and see!

Posted by: ChrisNPDrider Jan 31 2008, 01:33 PM

Killer! Did the F Prod 1.8 (I think) engine beat these #'s????
Race gas, more CR = 100HP/L?? Inquiring minds want to know

Posted by: rdauenhauer Jan 31 2008, 02:48 PM

181hp and 165FP of torque!! out of a 2056 WOW
Jake I didnt see it mentioned, was this combo using Nickies?

Posted by: Jake Raby Jan 31 2008, 02:59 PM

This was not a Nickies combo.. This last pull was also done on the same PUMP GAS that we used for last week's tests at 9:1

FP results will never leave my shop...

Yes, the torque is more impressive! We are at 90% more HP than a stock 2.0 and almost 75% more torque with LESS THAn a 100cc or 5% gain in displacement..

Gaining 90% more power at less than 7,000 RPM from a 5% displacement increase and running it on pump gas even blows my mind!

The engine is now of the dyno, it passed every inspection on the first try and is being crated for shipment as we speak.. The customer only paid for 150HP :-)
