This is a manual. I don’t have any draggy times but the gains are impressive.

Willow Springs Intl Raceway

Empty fwy drive home, 32mpg@avg spd 73
Took 1.8 seconds off my personal best at Big Willow and joined the "sub 1:30" club. Using a Cobb pro-tune track map by Mitch@DynoSpectrum. The track map is a de-tuned version of the 91 street map dynoed at 542hp/502tq. Both maps get about 1mpg more than stock on the freeway!

Wow 542whp! What mods on the protune?

Sub 1:30 is flying! Turn 9 scares the **** outta me. I got hit by a gust of wind which caused massive oversteer somewhere around 100mph once. Since then, I baby it through a bit. 32mpg is amazing for a 600hp car. Gotta love modern technology.

I have a C2S w/x51 kit. Added Akra cats/exhaust, Vektor headers, and AMS intercoolers. Wish I had your Tial intakes maybe someday....

Ksdaoski

Tuned on Dyno? Or remote?

fsmich

8 AND 9 scare me! Coming off 9, I had the left rear hanging yesterday, major pucker factor No wind,self-induced.
I told my track buddy I was done with Willow if I cracked 1:30, but we did have a ton of fun in the afternoon lapping with RS's,, race cars, and a 600LT.

3 hours on the dyno. 3 different maps. The beauty of the Cobb AP.

It was on the World Motorsport dyno right? A stock Carrera S put down 368whp on the same dyno. So you're up about 170whp. 93 octane is probably worth another 30whp.

93, 91 street and pre-tune akra/headers/intercoolers

Yes, World Motorsports. I believe Mitch said it was also where they did the initial dyno numbers for the Cobb OTS maps. The stock GTS came in at 423. My car came in at 469. 423+19(headers)+23(akra claim) = 465 . ( +5 for intercoolers on the dyno = 469)

So the 5xx is wheel hp or crank?

fsmich

Dyno wheel hp

The numbers reported at World MS are given what they call "Dynojet correction" which is essentially an additional 10% added to them.

fsmich

I agree World puts out some optimistic numbers. Dyno's are for tuning and documenting mod improvements.
With that in mind, Mitch has my car with mods putting out 107whp (taking in account your 10% correction) more than a stock GTS, or 157 corrected whp more than a base. All same dyno minus 10% on 91oct.
What we really need are some roll race numbers (60-130) and 1/4 mile traps. Mine are real close to a 991.2 Turbo S And the 600LT on the straights yesterday (track map).

Anyone with 7MT clutch slip issues?
