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..

P.J.S.

what kind of headers on the dog?

roberga

why does it fall off at the 6500-6800 mark ?

MikeAWD

Stock headers...

I am not sure exactly.. the previous pulls didnt have the dip like that.. It threw a check engine on the dyno and after that is when the dip was coming in.. Im thinking maybe related to the front wheels not moving while rears move..

how is the set of the pants dyno?

MikeAWD

Seat of the pants feel great.. The throttle response is night and day with the software.. I had no issues at all coming around a 2010 3.8L GT3 on the highway so i knew it had to be making some good power..

Is this the 3.6 or 3.8?

roberga

3.6

iLLM3

That's an MK1 GT3, assuming they didn't convert it to the 3.8 in which they would have stated it, it's the 3.6.. Stout numbers, and sounds AMAZING

leif997

agree 100% ^
great pulling power and it actually as linear by feel as shown in your chart. EVO and Alex did a great job pairing these two systems, didn't they??

(and don't forget about the beautiful symphony it provides!!! Just heavenly!)

MikeAWD

Im sorry i need to put 997.1 to be more clear.. I keep forgetting of the monster 3.8L 997.2..

Mike

MikeAWD

Yes the power is very linear.. As far as the sound goes, every time i drive it the music I listen to comes from the SW Exhaust not the Radio..

Too bad it wasn't dyno'd before the mods.

brendo

so if i interpret this correctly, it's 27hp across the range?

is this basically the result of the ECU tuning (fuel mix) and better air flow?
