Horsepower for all the (common) Porsche engine options Options

Okay guys....

Who has access to a Dyno here in SoCal?
Let's see some actual (rear wheel) figures.
I'm curious about my cars.

HP is great however I measure my 914 driving experience in (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/smile.gif) (IMG:style_emoticons/default/biggrin.gif)

This is a Porsche flat six - 320 HP and 295 ft lbs of torque. 3.4 liters of pure fun.

Tom, I'll take you for a ride in my /6.

You'll want a six.

Believe me.

(IMG:style_emoticons/default/agree.gif)

Pretty much guaranteed.

Basically what happened to me is back when I first got into the track stuff with a stock 73 2.0/4, nearly 20 years ago now, I was assigned a couple of POC instructors with well-prepped (but not extremely modded) factory -6's and those ride-alongs at Streets of Willow were the proverbial first couple hits of crack...

(Slightly OT) One of the culprits back in 2001 - Martin Jansen's six, a neighbor from Agoura Hills, now retired from racing. Last I spoke with him, he still had the car but had retired from racing.

My current engine dynos at 230-235hp at the wheels @ 7500rpm, a tick under 200lbs-ft torque; 7R case 2.7 with significant power and reliability mods. Deafening and chugs fuel like there's no tomorrow. Love it.

I would truly love something like an 3.0 RSR w/ MFI in this car, but at probably 50-100% more $$$ vs. the already spendy setup in there now...not happening.

Lets call 120 ( big /4)

Oh also want to point this out as some people get very confused from inaccurate advertising. K&N air filters add zero hp.. Don't buy into the hype it's complete b.s... I am not arm chair QB ing here this is from real data in my former life as an experimental aircraft engine builder.

If you’re talking about my post, I’m simply listing the modifications. I don’t mean to imply that the K&N increased HP. But a blanket statement that it doesn’t is incorrect as well. I’ve seen testing where it improved and also testing where it hurt HP. It depends on the car.

Rob,

I will respectfully disagree.. I did this as part of factory dyno tests and back to back it didn't help whatsoever.. It is pure marketing.. I was the one actually doing the testing along with factory engineers. The only advantage was it was reusable. We actually proved that it increased wear to the engine much faster..

Filters are all about filtration/Flow in CFM.

From what I read on them they flow no better than any other filter and their filtration is crap.

Sorry for hi jacking this everyone.. It was a nervous tick of mine.. Back to regular scheduled broadcast..

From what I understand, it’s all about finding the choke points on the engine. It’s usually not the air filter. I know that on a 3.2, it’s proven the be the AFM/flapper box.

Seems like a useful thing to have summarized somewhere. While you can build just about auybof these to be a monster compared to stock, how about if we list stock values for now as one reference point?

1.7 flat 4 - 79
1.8 flat 4 - 84
2.0 flat 4 - 99
2.0 flat 6 - 109
2.2 flat 6 -
2.4 flat 6 -
2.7 flat 6 - 150-200
3.0 flat 6 -
3.2 flat 6 - 213-240
3.6 flat 6 - 275-300

Look like the right list?

I am not exactly sure, but lately I have been driving the six rather than the four. Such fun! Headers. Thinking about changing out the stock chip.

Errrr......
Yes this is true. The dreaded six letter tax. Used one.s 6-7 k.. Rebuilt 20k. On topic though......air cooled 2056 15jk.

@Oscar - I am aware of two 'porsche friendly' dynos around LA -- Ed Pink has one in the SF Valley (2WD) and World Motorsports in Torrance has an incredible fully-enclosed AWD dyno with forced-air cooling... Also POC has a mobile dyno (2WD) at many events ie Willow Springs for classification purposes; usually $60 for 3 pulls.

I was really pleased that my current 2.7 dynoed almost identically in 2014 and 2017, and still seems equally strong now... My prior build only survived about 1.5 yrs of track abuse.

Long day yesterday....yep. Wrong tax.

Thank you sir!

1.7 flat 4 - 79
1.8 flat 4 - 84
2.0 flat 4 - 99
2.0 flat 6 - 110-170 (~210 race)
2.2 flat 6 -125-180 (~230 race)
2.4 flat 6 - 130-190 (~250-270 race)
2.7 flat 6 - 150-210
3.0 flat 6 - 180-204 (~310-330 race)
3.2 flat 6 - 207-231
3.6 flat 6 - 250-285 (300 with rare Powerkit)
3.8 flat 6 - 300 (310+ race)

Look like the right list?

^ Quick stab working with some factory numbers from reference materials here. These reflect the lowest lows (typically but not always U.S.-spec), and the highest highs (typically RoW). Tried to add some numbers for same-displacement race engines from the factory in period, but not all of them (2.2, SC/RS, etc) are accounted for.

As you note, these can be built into just about anything, and engine builders and hot-rodders have learned a lot since these engines were new—the youngest among them is now 21 years old while the oldest is 50+.

I would have been happy with the stock 160 hp from a 2.2E with my budget build, but it made 169.9 hp at the wheels when we dialed the carbs in. Mods were Solex cams, headers, a little compression, "a little head work" (I am still suspicious), and crank-fire ignition. Stock Mahle 2.2E pistons, mag case, and Weber 40s...nothing special...but I suspect tricks gained over time allowed John Holleran to build a 2.2 "E" that makes more power than a stock 2.2 S did. And it's more tractable too, feeling like a 3.0 down low with the only downside being it doesn't love going past 6000-6500 rpm. It'll do it, but it doesn't race to redline up top. Offset is very usable power.

you can't turbo a 914

Portable? $60 for 3 pulls? I wonder if he'd be willing to measure a group of 914's. Pretty sure there would be at least 15 people here willing to meet and have this done. @ValcoOscar @Larmo63

The past two summers, Craig at World Motorsports organized weekend Porsche dyno days via Rennlist which seemed to work out great - at least for me as I got there early (this was re. my 911). Their facility is amazing and is available just about anytime M-F. A group of us could try organizing a similar weekend thing.

If you have 15k to 20k laying around for an engine swap then 3.4 to 3.6 is the only way to go. If you are looking for best bang for your buck JDM all the way. I have had 350 to 427 small block Chevys in my 914. 5 to 10 grand minimum each engine. Then I went to a 3.5 liter Honda Oddyssey engine for 500 bucks 240hp 240 torque. Andrew damaged the engine smacking the redline at the POC, and it still drove home in limp mode. Instead of me pulling engine apart I bought another one for 300 bucks and in one day was back on the road again. Oh I forgot to mention fuel injection and V-tech hahahahahah (IMG:style_emoticons/default/lol-2.gif)
