Ok guys we finally got a chance to dyno my GT3...Normally i would have before and after #'s as thats the way i like to do testing but i was over anxious and modded the car before I got a chance to dyno it. The tune is PERFECT all motor.. It also shows that EVOMS spent some time tuning these cars.. In 4th gear the car goes richer as it should when it sees more load which is perfect for Road Racing conditions.. Any questions just ask..

Below are the mods on the car..

Sharkwerks Race Exhaust System ( Stock Header & Cats )
EVOMSit Software
BMC Filter


Here is what the car made 1st pull in 3rd gear..





This graph shows my car @ 397 vs. Another 997 Gt3 With Filter, Headers, Chip & Exhaust in the same gear.. The midrange shows +27hp also.. As you can see 4th gear picks up some power.. I think ill take Alex @ Sharkwerks advice and stick to stock headers..

 

The torque curve looks delicious!

 

I thought the same as well.. Its making 250 and up from 3k to 8K+.. Cant complain about that!!!

How much crank HP would you relate 397 at the wheels? What's the driveline loss with that car (can't be much since there's no driveshaft, right)?

 

yep, love to know what that means at the crank?

 

When I had my 997tt tested on a dynojet with front axle disconnected the drive train loss was about 15%, same on my Cayman.

 

Id have to say close to 450Crank.. Driveline loss is around 12-15%.. No driveshaft, just axles in rear.. I ran a brand new 2010 3.8L which is 435 crank and was pulling him on the highway wide open so i know i have to be over 435 crank for sure..

 

That's awesome. Thanks!

 

Thanks for sharing. Great results!

 

Congrats on the great result! Sounds amazing btw
