GIAC Tunned - 535 Wheel HP - Dyno Inside

[ari1856]

Hello All. Long time lurker, infrequent poster. I have owned my TT for 4 years now. Picked it up in 06 with 9700 miles and totally stock. It was the realization of lifelong dream. You know the commercial: ...for teh truely afflicted there is decade or two on betweeen"

It was originally an X50 and had basic performance mods added over the first 2 years.

For comparison sake Here is my car's dyno with the original K24s with exhaust, wastegates and GIAC Flash. This was a dynojet at an independent third party facility and having gone through rounds of mods after this I am CONVINCED that 500 wheel HP on this dyno was nothing close to 500 wheel HP on GIAC's Mustang Dyno as you will see below. The car is SO much more powerful now. I don't know how much power it really had at the time... maybe 430 REAL wheel HP (540 crank)?

I upgraded my K24s at my favorite shop Speed Gallery in Studio City this year with the following mods:

Tial 2860RS (Ball bearing, water cooled Garrett turbos)

EVO Clubsport ICs

EVO Diverters

SpeedTech Y-Pipe and HOSES

60 lb injectors

Hitachi MAF

AAsco LWFW

New Sachs Clutch

GIAC was gracious enough to allow me to upgrade my K24 file which i had purchased over 3 years earlier.

The car was very fast and spool improved tremendously. But I felt like the car wasn't running very well at full throttle. After contacting GIAC, I took the car down there where Garrett and company quickly realized that the file I had was too aggressive (it was an intercooler file). They dyno tuned the car and gave me custom file which while significantly less aggressive in timing and boost, allowed the car to run better and stay off the knock sensor. I picked up about 75 HP and 75 ft lb of torque that day and the car was utterly transformed.

Here are the before after graphs:

In looking at the intake air temperatures GIAC was adamant that the car would run better (as is evidenced by the "stair step" HP curve above) with some intercoolers and offered to review the tuning as well address some minor small throttle driveability issues once I installed the upgrades.

I chose to go with EVO Clubsport ICs and Speedtech Hoses and Y-pipe. The EVO intercooler design allows you to remove the restrictive factory style connectors and combined with the Speedtech Y-pipe really cleans up the airflow path of the compressed air all the way to the throttle body. Once all that was installed I again dropped off the car to GIAC for fine tuning.

I have had extensive private conversations with several Porsche Turbo owners running non factory MAF setups from several different vendors and the general consensus has been that you have to give up some driveability when you ditch the factory MAF, this is especially true when going with a LWFW. I am very nit-picky and particular when it comes to the small details and really expect stock like driveability. I am very happy with the results. The newest LWFW file GIAC installed is truly BUTTER smooth and stock like just as Garrett had promised.

Now on to the good stuff! Keep in mind that this is a TRUE 91 octane file, running real 91 octane at 18 PSI ~ 1.22 BAR.

GIAC's dyno registers a stock TT at about 330 WHP like one would expect. I am very happy knowing that my car is making about 200 WHP more than a stock 996TT on California 91 Craptane gas and 70 more WHP than a stock 997 GT2 on the same dyno. I can't wait to try some 104 and use my GIAC handheld switcher to see how that feels!

I figure the car now has an honest 650HP on 91 octane and 700? HP on race gas. It's done. Put a fork in it!

Special thanks to the following vendors and members

The crew at GIAC for putting up with me and going out of their way to make sure the car runs like I wanted it to

Congrats, not bad numbers. Its hard to imagine how anyone can keep these cars stock with the perfomance possible in these motors.
