New 2270 engine kit combo, Testing is complete! Options

[Jake Raby]

As you guys have probably read my engine program and engine kit side of the Type 4 Store have been going through some big changes with the development of the "New Generation" cylinder heads. Len and I started this development many moons ago and we have finally got the program down to the "T". These heads have given my most popular kits and complete engines a solid 15-20% gain in power over their counterparts with our previous cylinder head technology. We will not be revealing exactly what the heads entail to the publi until the first installment of the Type 4 Build up article is circulated in Hot VWs in early May as we utilized these heads on this engine in the article, but in the mean time we can let you in on some data I have gathered both on my dyno and in my 66 Beetle test car.

To do this the best way possible I'm going to include in this post an excerpt from a post I made on my forum explaining in detail the info we have attained during this past week of testing. Also I will include info and data from todays event, the Southeast dyno day, where I brought out the first test engine with these heads to the public.

Keep in mind before reading further that this is a 9.3:1 engine, built from one of my new engine kit combos. It was running on pump gas and has no fancy tricks. Also keep in mind that this engine made more power at the rear wheels than this exact same engine typically makes AT THE FLYWHEEL and all that was done was a swap to the "New Generation" heads... This kit isn't going to cost more than the current 2270, and YES it will work GREAT in a 914, the torque is astounding!

......and yes, development will continue with these heads on all my most popular engine combinations. We are seeing such huge gains and we are so into this test work and the program that I have suspended further Turbo development until we get at least 10 more of my recipes equipped with these heads for back to back testing- MY GOD IS IT FUN! You can expect to see a 200HP 2316cc engine on pump gas, with cool temps not needing exotic components with these heads as a ROUTINE occurance now, we have already done it and know how to easily replicate it!!!!

The past two years I have taken top HP and Torque at this event, last year I had first and second spots filled, but this year I let the boys play while I did some R&D work on a new engine kit combination utilizing the "New Generation" heads. I set aside the huge numbers to gather some data from a "regular" engine built with 100% off the shelf parts, with the newest 2270 combo we are now offering in kit form.

I have all the datalogging equipment installed in the Blue Bug and witnessed some INCREDIBLE temperatures from this engine on the 2 hour drive to and from the event. I had planned on drag racing the car/engine tomorrow in the Street Car challenge but my dad has his health issues so we decided to stay close to home. The gearing is definately set up to benefit the 1/4 mile and not a Type 4 thats going to be adily driven, with it's 1.04 4th gear. Due to this I was turning roughly 4K RPM at 65 MPH which in 80 degree heat would put a Type 1 to it's knees quick in the oil temp department, the highest oil temp we noted to and from the event was 190F! I only have a very small external cooler, 24 plate Mesa thats 12 years old and probably half filled with crud by now!

The head temps were unreal! The biggest CHT difference that was noted on the 4 hour trip was 23 degrees! The highest CHT I spotted was 332 degrees with most of the time the heads running between 290-310, I only hit the 332 number when pulling a huge hill while accelerating up it.

The most amazing thing is I was still attaining 22 MPG while turning 4K RPM for the entire trip! This is absolutely made possible by the effectiveness of this combo and the effects of the "New Generation" cylinder heads.

Now on to the POWER part of the story...

The dyno operator was a "New Guy" so he had no prior experience with ACVW engines and this morning he really sucked! I was #4 on the dyno and he didn't rev the engine high enough on the first run and acted like he was afraid of breaking something. I told him to stand on it for the second run and he did and got a better reading of 138 HP at 5500RPM and a whopping 147 lb/ft of torque at 3,400 RPM with a wonderful graph that I'll post later. This engine is all about usable power and the plots prove this as the torque curve is damn near flat from 2,500-4,800 RPM!

The engine was a tad bit lean but I didn't figure it was lean enough (13.2:1) to warrant a jet change. Later in the afternoon several of the guys that went earlier in the morning with me and had shabby runs had then re-done, as the dyno operator was doing much better after a few cars hit the roller and he got more used to them.

So we tossed the bug back up and did 3 more runs, 1 with the fan belt, just as it was earlier in the day and then two without the belt. Max HP without the belt ended up being 147 HP at 5,800 RPM and max torque was a whopping 155 lb/ft at 3,500 RPM! Remember that these are RWHP numbers from an engine that was built exactly as it would be from one of my kits, not a single "Trick" was added! Also remember that in the past the 2270 was only good for about 150HP AT THE FLYWHEEL in "kit" form so this new kit and the "New Generation" heads have given us a solid 20% power increase without impacting reliability, or maintainability at all! This kit is running COOLER head and oil temps than any 2270 of this stage of tune ever has before! As a matter of fact this engine made MORE power on the same dyno than the 2316cc Hybrid that was in my 914 at this event last year, and it did this without having to rev 7,500 RPM like the 2316 needed to, this engine was all done by 5,800 RPM which makes it last forever and be easy to drive at the same time!

On the last dyno pull a bunch of the guy wanted to hear the engine rev as high as it could and were giving me a hard time so the owner of the dyno got me out front with him and told ME to tell the operator when to stop rev wise. The engine was all over by 6K making power and all the revs were pretty worthless, but I decided to entartain the crowd a bit because I had already taken this engine well past 7K on my dyno and had plenty of valve control left.... So he keeps revvin, revvin and revvin and I finally hear it run completely out of air and get on the verge of valve float, so I had him kill it at a whopping 7,400 RPM- Remember this is all off the shelf parts, nothing lightened or radical! The crowd was happy..

I'll be doing a lot more test work with this engine in the Blue Bug over the next month or so before I have to change the drag gear box out for my tall geared tranny for the trip cross country to California. I plan on taking it to the local track for the next several test and tune days to get some 1/4 mile logs for HP and torque as well as some temperature data logs. I will also be doing the final testing of the 914 version of the DTM on this engine in the bug so it'll get plenty of time on it very soon both at the track and the street as I'll be driving it 80 miles a day for the next month + from work to home and back everyday.

You'll be seeing A LOT more of this engine very, very soon!

So there ya have it a new engine kit has been born, and dyno proven with great results.. It'll be available in about 2 more weeks for purchase through the store as I have to break it all down and come up with the prices of components, don't expect it to be any more expensive than the current 2270 kit, just more powerful.

Are you gonna let McMark Build these too?

Them numbers are lookin damn fine there Jake

[grantsfo]

Sounds like fun! What combo of carbs, headers and muffler were you running to get those hp and torque numbers?

[Jake Raby]

44mm IDF carbs, off the shelf with 140 main jets and no other changes...

A-1 conversion header with 2.5" magnaflow muffler (we are now developing an A-1 for the 914 :-)

Mallory Unilite dizzy off my shelf with o internal changes made over my settings as we sell them.. 12 degrees initial advance, a faster curve and 30 degrees full advance.

Like I said, nothing was out of the "ordinary" with this one.... For once I went back to the basics and I have to admit that it's not as much fun as driving the same car with 235 ponies last year, but it damn sure moves out and runs cool!

3 years ago this same engine made 140 HP at the flywheel! Now it weighs in at 170 at the flywheel and these numbers posted at the rear wheels! Torque went from the 150 range at the flywheel to a whopping 180 in the same amount of time..

All of that and we haven't lost a damn thing, the engine runs cooler than it did 3 years ago and with my "raod gears" it will get better MPG I'm sure. 3 years ago this engine averaged 26 MPG and I got 22 today with a set of drag race gears in the same car!

This may not seem like crazy power to many guys that just look at peak numbers, BUT if you could drive the car and see how well it does as a daily driver you would be amazed as much as I am....

The evolution of the 2270 added another chapter today.....

Haven't decided just yet.. We need to see how he does with what he has on his plate right now and what the results are with customer satisfaction first. I'm sure Mark will do a great job, but I demand a lot when someone will be marketing an engine with the ties I have with this combination..... Time will tell.

Just a bump to keep the infomertial near the top. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

[Jake Raby]

I was waiting on that.... I thought you might have been in the middle of your Saturday afternoon siesta or something...

I would buy TV time but it's too damn expensive! Remember- I'm a 914'r too so I have to be a cheep bastid!LOL

[J P Stein]

My pleasure.....as usual. Hay, this is another bump (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

[Jake Raby]

Damn...
You sure are being nice lately....

Thats scary (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

[Joe Ricard]

Maybe JP got whooped by a type IV. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

If'n I wasn't so far maybe....... (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif)

Or he started reading the rule book and found X prepared rules attractive...

Raby power and 1640 pound teener is going to be FAST.

kickass jake!

I've always been "nice".
You aren't 911 engine bashing, I ain't T-4 bashing.
I gotta admit, some of my bench racin' can get a little....ah... abrasive, but I'm gettin' old & mellow. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

[Jake Raby]

I'm the same way.. I get so into it that I go off the deep end...

BUT this post won't get that way because no one will START the bashing.....

Right????

I won't if you guys won't, so lets see if we can have a civil reunion for once!

[grantsfo]

This is great news. I knew you could do it and appreciate your efforts to bring a more cost effective high performance T4 kit to 914 owners. I'd love to see a couple of these engines in Northern California.

Hell I might have to breakdown and buy a VW to justify getting one of these motors. I'm thinking a Baja style VW Thing project would be cool!

[Gary]

Cool - OK had to do it - just dropped a subscription for HVW's...

So Jake will our stock tranny be fine? I bought a new flywheel/clutch from you, will it still be the right one, I haven't installed it yet. Do I need to send you my old engine or heads as a core to get one of these or will it be an off the shelf item? Would like to know if you are going to Hershey, I haven't forgotten that lobster for ya!

[Jake Raby]

The stock flywheel, and pressure plate will be fine with this much power, you would only need to upgrade the clutch disc to a 6 puck unit that I carry to hold the extra power. I hold up to a tad over 200HP with the stock pressure plate and flywheel with the upgraded disc...

No cores are neededfor the heads! These heads are BRAND NEW so we don't need any cores for them- this head program totally abolishes "rebuilt" heads from my shop forever!

You can sell your 2.0 heads to help pay for the kit/heads..

Ayup, Steve Nilsony (sp?) put a whuppin' on me last spring.

As for Joe, you got 3 chances at me this year. WCC, & 2 at the Parade. Come & git some. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
or, fly up to WCC & I'll let you drive a real AX car. (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif)

Steve is headed to the Parade & Randal was rattling around about it. 2 T-4s, both of which will prolly kick my ass. There's still time for some one like BRITIAN to register and drive my car
in the Parade. Beating this old fart at AX ain't that tough. With a decent driver, beating my car becomes more problematic.
