Dyno run tomorrow. What should I expect?
 
The dyno will be from the wheels, not the crank.

The motor is a '97 V-ram 3.6 with a Cyntex chip, K&N cone air filter, Stock 993 headers with extremely free-flowing exhaust.

What kind of numbers should I expect?

I'll take a wild assed guess...237

JonT 05-21-2003 11:10 AM

i'm guessing 242 at the wheels.

265...don't think too much will be lost from the crank HP.

Mikkel 05-21-2003 12:34 PM

260?

I know this wasn't supposed to be a game but, I'll bite.

Accounting for loss of velocity through the flux capacitor and increased molecular anti-forces acting in counter with regenerator curcuit, I'd say 238 at the wheels.

251HP at the wheels!

RickM 05-21-2003 01:35 PM

249

Huey58 05-21-2003 01:42 PM

Name that tune!!!

Paul Thomas 05-21-2003 02:34 PM

I'll go 275.

CamB 05-21-2003 02:38 PM

261hp at wheels, 287hp at crank.

Joe Bob 05-21-2003 02:50 PM

271 at the wheels....

Mike. You're scaring me. Are you pulling 271? I was thinking around 240. We'll see!

C2 3.6 with stock chips and exhaust: 247 (porsche, used as a base line for the following measurements)
C2 3.6 with Cyntex chips 263
C2 3.6, Cyntex chips, B&B Exhaust 272
C2 3.6, Cyntex Chips, 1-7/8" headers, Dual in-dual out muffler 282
C2 3.6, Cyntex Chips, 1-7/8" headers, dual 2.5" stainless Supertrapps 286
993 3.6, Cyntex Chips optimized for Varioram, Supertraps 298, 305 with open exhaust
>>>>>>>>>>>>>>>>>>>>>>>>>

298 x 85%= 253

But I always was sceptical of the 15% drivetrain loss.....so I added a few hp....

So JUST to prove me wrong, it will hit 253.

Glasgow 911SC 05-21-2003 03:04 PM

243hp....What do I win???

Milu 05-21-2003 03:13 PM

252 at the wheels.

Kemo 05-21-2003 03:20 PM

an even 250 is my guess :)

Deeks 05-21-2003 03:52 PM

251 ?
Does the winner get a free ride ??:D

Bill Douglas 05-21-2003 03:58 PM

247 :)

245 rwhp sae corrected if its a Dynojet dyno.
258 rwhp sae corrected if it is a Mustang dyno.
Now if the intake temp is over 75F add 2% because the correction factor over compensates for the heat. If your not pleased with your, "Dyno" numbers come back in the dead heat of summer and your actual numbers will be terrible but your corrected will probably be record high. SmileWavy
Just my wild arse guess.
