Hi
What are you getting and from what size and spec aircooled engine ?
I'll start

My 1911cc with mild cam and twin 40 Dellortos, 050 distributor and Bursch exhaust gave 115bhp last time it was on the rollers

199.5 rear wheel hp from a modified 2.7 911 Engine.

240hp at the crank.
7K redline.

I have sir keiths old big /4

2366 with webbers ,header etc

Keith said its was making about 145 horse .

228hp at the flywheel with the 2687cc six

Raby-built 2056 with dual Weber 44 IDFs

Fully built Audi 1.8t running on a way to big turbo and low boost.
~375

High boost will be up way, way up there. Details in my build thread.

~550 - 600hp, 4g63 Mitsubishi engine. Details in my build thread.

I think y’all missed the “air cooled” spec in the first post... but hey, my 455ci bored .03 over puts down 600+ ft-lbs. it would never fit in the 914...

Not running yet but hoping for 130+ from my 2.3 with MicroSquirt. But more importantly I am looking for torque!

Raynekat and mine are air cooled P6's.

3.2: 235.5 @ 6440

305 at the flywheel according to the guys i bought the engine from, never confirmed that number though.

3.6L /6

What modifications? I have ‘77 2.7 stock except withWebers and Street compatible cams.

Not bad

But i just realized ive never had my engine over 4200 rpm

Couldn't imagine reving into the 5k -6k and 7k's rpms


So i guess ive never really felt the power

I have not had it checked. 2.3L 6-cyl, car weighs about 2300 with me in it,
and I can do 0-60 in 6.6sec (still in 2nd gear). Maybe 150-155?

207 per the factory spec. Andy had to remind me of his 100 more HP...

Factory stock 3.2 Carrera motor. Oh, with some MSDS headers so probably 220! Take that Andy!

Interesting conversation here. I’m with ya I couldn’t imagine taking my 2056 up to 6k maybe 5k. I generally shift right at about 4000 to 4500 high side.

Y’all better hope Jake doesn’t come around here callin’ out pussies... drive it like you stole it!

What really....,you say some weird stuff hard to sort the cr#p from what you really mean to say...maybe I'am not taking it in properly,just had to say,sorry if I don't take it in ? .

Only guessing but 2.2t strong motor with headers and carb upgrade ,bum seat feels like it after many cars built in this HP range,reckon 135hp,works for me fine.

650hp. T1 engine with 50hp + a 600 shot of NOS.

Original 2.0 rebuilt to 2.0E with Webers. 120 at the wheels. Ancient dyno video in my signature...

You said it right, tub.

Good to see you still on here, it's been a LONG time since we last met up!!!

april fools was last month...

are people pulling my leg that they don't ever see 5,000rpm?
crazy


mine is around 180, at 7,800 rpm (has valve train to protect up to 9K)
1800 lbs... 2 liters!

Jake actually told me to shift around 4200. I generally shift in the mid 4000 range. Power starts to drop off after that.

wth.. Though been many years since I had a type 4 the tech now around can sustain big numbers and longevity to intended redline..

Those that don't drive like that baffle me but I do understand just the cruzing mentality.. Just not entirely my thing.

Which would be correct looking at the dyno information. Up until that range you see the substantial increases in torque and HP in relation to increased RPM. After that point, you begin see limited return in HP and lower torque. So while it is fun to rev it up to 6K+ but that time would be better spent in the area of the curve where your torque and HP increasing with RPM. But I could be wrong.

It depends.

Your own chart shows power increasing well past that. Your torque # seems to max out
there, so acceleration in that gear would then start to decrease. But when you shift up
it will be much lower wheel torque due to the gear. Most of us would go for the higher
RPM and more fun. I'm sure Jake built the motor to deal with it.

I'll see Jake this weekend. I'll ask him about max safe RPM for my engine.

My 73 1.7 Around 80hp of raw power! 0-60 around 1/2 hour

325-350 est. 3.6/6 modded. Makes beautiful noise at 6800 rpm. Details in signature.

I have pretty much the exact same set up, but with Webers instead of Dellortos. Haven't dyno'ed it ever, but the butt sensor says around 100bhp. Zero to 60 is.. well... not something we need to talk about here.

Pretty good for 3.2, is this at the flywheel or Crank? Is this Motronic or Carbs?

How does one go about finding out torque and HP? Are there any shops that do this in the northern LA area? What does it cost?

I have a stock 1.7L, but it would be nice to know how close I am to the factory numbers.

3.4 twin plug, Weber 46's.

That is my setup as well but I'm getting exactly zero hp out of my engine. I think the problem might be lack of compression due to a 1,000 mile gap between my heads and cylinder tops. Hopefully soon the heads will come home from Sonoma and I can fix that. What pistons are you guys running? I was guessing that with euro flat tops, the mild cam, Weber 40IDFs and the Bursch that I'd be making around 110 hp? My goal is to be able to spank all the smug bicyclists around here in 0-60.

Heh, you're right. I missed that part... still, though... my 2.4 i4 is in my 914

Sounds like a recipe for a grenade?

I was surprised you can add a draw thru turbo cheap on a vw type 1 to double the hp. I had a 2110 running about 15lbs of boost was about 240hp I think

Mine was built by FAT Performance 15 years ago. Dyno. test showed 147 hp at 5500rpm. 2.2 liter type IV with 44idf Webers. 8.25:1 CR. Good low end torque and fun engine to drive.

(Holy $hit, that was 15 years ago)??!!!!

Who cares...this is how I measure my HP

At the crank. Motronic, 10.2 Mahle Nickasil P&Cs, Web 20/21 camshafts and Tangerine Evo 6 headers. Small port heads.

Date on the dyno sheet is when they installed the dyno. My power runs were done in November 2017.

0 HP , motor still laying in pieces on work bench I'd be content with ~90HP right now ... another month maybe?

Nice! I'm running a warmed over 3.2 also, but I have PMO carbs. Pluses and minuses I guess... gets terrible mpg, but oh man the sound! Luckily its not my dd.

I'd be interested to see what my engine puts out. It's a 3.0 with J&E pistons (10.5:1), webcam GE60 cams and PMO 46mm. It is actually pretty sluggish until around 3k RPM then it kicks in. Not the best for driving around town.

Good figures for a 2.2,everthing I have read about there engines points to them being bullet proof.
A friend had a 3.0 FAT T4 in his buggy he imported from the USA ,it made huge power and cleaned up where ever he raced it in my country.

That's good to see. I have a similar setup. Differences are 40IDF's with 28mm venturis, 9550 cam and Mallory Unilite.

Based on previous 912's and 911T's I've owned/driven, I'd say I'm in the same ballpark. This 914 is quicker. Was in a backroads drive a few years back with a couple of 356 S90's behind me. They couldn't hang.

Wish list would be better exhaust. I don't like the Bursch.
