Put my 964 C2 on the dyno today. The car is the standard 3.6L with 993SS cams, lightweight flywheel, GHL full exhaust, Wong custom chip (93 octane), and the stock airbox. Peak SAE corrected numbers on my third and final pull were:
258 rwhp @ 6300 rpms
238 rwtq @ 4900 rpms
So assuming 15% drivetrain loss the flywheel numbers would be:
304 hp, +57 hp over stock (247 hp)
280 lb-ft, +51 lb-ft over stock (229 tq)
Not too bad for a 26 year-old car with no coolant.
The air fuel starts to lean out some up top past 6k rpms. I'm thinking about having Steve Wong add a little more fuel in there; what's a good number to shoot for?
Anyone have any other 964 3.6L dynojet charts they could post up so I can compare the topend? Thanks.
that's impressive. my bog stock fresh rebuilt 3.6 with 993 S cams (the only "mod") runs super strong with stock exhaust and wong chip. Look forward to getting rothsport headers on it, 991 turbo s muffler, and LWFW and getting it on the dyno. I'd be thrilled with those #'s you posted.
Interesting... mine is a freshly rebuilt 3.6 with stock flywheel, 993SS cams, cat delete, primary delete, and a 91 octane wong chip. It did 251/231 at the same peaks and identical curves. I'd be tickled with your results too...

are those WHP numbers for you or converted crank? I assume wheel?

Thanks, yes I am definitely happy. The car is a blast to drive in its current form. Let us know what your car puts down when it's all put together.

Greaser5 do you by chance have the raw dyno run files, they should be a .drf extension? I could do a quick overlay in Dynojet's viewer program for a good comparison. If not you might be able to call your dyno place and see if they store old runs on their computer which they could email to you.

Wheel.

I don't have them, but I bet I can call the dyno place and have them email em over. I'll do so!
If you are running stock fuel injectors, my understanding from other threads, you may be maxed on fuel output. I am sure more knowledgeable people will confirm.

I already sent my dyno run files to Steve Wong for an updated chip. He thinks adding a little fuel up top should take care of it. I would be curious to hear power levels the stock injectors max out. Is there any easy way to measure injector duty cycle?
Hi , very impressive result ,
You will probably better of fitting bigger capacity injectors this is one of the main restriction ,
You want them to run at 80% of capacity ,
That's my understand , I run the 330cc .
Bad photo of mine sorry. Don't recall what happened to the paper version to scan.
Car is a 93 with cup airbox, 100 cell cat, Magnaflow muffler custom chip by protosport and LWF otherwise bone stock internals, Was still running with A/C when these were done. It was quite quick on the track and pulls quite strong.
I believe with using 15% loss that comes to 291 BHP and 279 torque
I am still trying to find my base line charts but IIRC the car was putting down around 210 RWHP before the changes.

Damn. Those are good numbers for as little as you've done. Smart setup.
Both you guys have shown me that I should have done the LWF.

Nice numbers Anthony, especially with the stock cams. Looks like your A/F was doing something similar to mine going a little lean in the upper RPM band. Do you by chance have the dyno run files?
I know in my RS the difference with 91 and 100 octane map is about 12hp and about 5 more tq. Surprised if 10 difference between 91 and 93. 402 wheel. It's a 3.6 too!!! :-)
