Hi there I dynoed my GT3 with a AWE Exhaust System
on a Dynojet 248 Dyno, and got 378 WHP, will put the dynosheet tomorrow

Tony

 

Congrats on your results. What was your baseline stock dyno result?

Did you do ECU software upgrades as part of your mod package?

Anyway good luck with the headers and the GT3.

hi there I do not have a baseline this is the first and only pass tried a second pass but the car cut at 6000 rpm! some lighs came on...(abs and traction control error). will do some more dyno next weekend
thanks

 

Good numbers! It's louder than the stock exhaust?

 

You need to know what kind of gains you have achieved from your mod.
Did you do an ECU software upgrade at the time of the headers from AWE?

Hi there I have not done the GIAC upgrade yet, the ECU is stock.

About loudness, yes the car is much more louder than stock.

 

The GIAC software should give you another 10 to 15 rwhp.
Go for it.
My GT3 put down 392 rwhp with headers and GIAC software.
You will be happy.

Enjoy your car.

- The check engine lights (cel) is normal
- do not worry about it as all gt3s throw this code when on the Dyno - there is no issue and you can continue to Dyno it afterwards with no effect
- after your Dyno session is over (3 to 5 pulls) until you get consistent numbers - the CEL light can be easily reset with a VAG tool (awe will confirm this if you phone them)
- next time you Dyno the car make sure you do a number of pulls and make sure the car is getting lots of cooling with all the fans that they have so that the ECU does not pull timing
- also the car does need time to adapt if you just had the exhaust and headers installed as the ECU will immediately pull timing when it senses a change - my car took about 200 miles for the computer to return the timing it pulled when I made an exhaust change - to help it along take the car on the highway and do 10 WOT runs in third gear
- finally to be consistent make sure you run the same type of fuel, post this information and try and pick a day where the temp is not 100c

- when you do all of the above I suspect with 93octane your car will post higher numbers 385ish on that type of Dyno

- I have a slightly more conservative opinion on software - I think it is worth about 5whp on 93 octane - a little more on 100 octane as the tuners will push the timing more than the stock ecu will with better fuel

Hey 997gt3north, your response is a good read. I never had a CEL issue.
The baseline stock dyno results revealed slight variations but all within the 355 to 365 range. The FVD headers provided good result in rwhp gains. The GIAC software was added months later.

The dyno graph depicts the green bottom line as the stock results. The red midline are results with the FVD headers and the blue top line are results with the GIAC software.
The more significant improvements are seen in the midrange, 3300 to 5600 rpm. Specifically gains of 41 ft/lbs torque and 35 rwhp at 4500 rpm.

I was very happy with the GIAC software upgrade but I am presently investigating additional software mods by another tuner. This is the tuner who has made my E60 M5 the monster it is.
I will follow up with more info once we get into the project.
The goal is putting down > 400 rwhp without doing a 3.8L conversion.

Cheers and good luck to all,

Ranger

 

juan, please keep us updated with the gt3 project

 

I sure will. I will be working closely with Abid at ASR Engineering on the GT3 project.

Cheers,
Ranger
