The CG was a bit lazy to come down..On the flip side to that a run on the highway in 6th WOT for 2 miles or more would show a lower temp then the stock. Unit. In the long run I sold the CG and kept the stock. I actually use it in a lot of our TT conversions. It is a fine intercooler IMHO and was and still is my choice. My TT was setup making 438.7RWHP. That was a 2WD dyno.

My phrase "stop- go" was maybe not quite what I meant

Stephen,
Does GIAC write software to work with additional fuel for this application? I thought the A/F plot looked good. The engine runs great and sounds great idle through WOT. Good point about the seal around the top of the intercooler. Thanks.

TB, Ok, gottcha. Yes, that would be far better than our typical jaunt into work. That is unless I oversleep for an hour ![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
Keith,
Your charts look great. If I recall the highest point was about a 12.4AFR. I think this is perfect and the 9s are certainly to low. Unless you are running out of fuel and need to compensate, and it doesn't look like you need to I wouldn't run it. Garrett writes most of the programs properly and therefore the need for higher rail pressure is not necessary. The higher rail pressure is actually a band-aid if you will, not the fix. I think your set up is ideal and running well.

Keith - Great news - thanks for posting the data. It will be very helpful to compare my data since I am running a different chip and my turbos are a little different (sport compressor wheel and clipped exhaust wheel). I am looking forward to getting my car on the AWE dyno to figure some things out. On the Autothority dyno, my car reported 380 rwhp in stock configuration - your stock reading was 79% of that at 300hp. 79% of my 500 rwhp on the Autothority dyno is 395hp which is more in the range of what you are showing with the mods and what I expect to see on the AWE dyno. I am hoping to solve the issues with my power dropping away after 5500 rpm. Maybe it was the gasoline I was running. I have been running 50/50 93 octane and VP103 now. It seems to run better. I'll see what the dyno says. I was hugely dissapointed to miss the 12-22-03 dyno party at AWE. That would have been the best time to get some relative runs.

Interesting info, Keith, thanks for sharing. A gain of 70 horsepower and 60 ft-lbs of torque must feel great, particularly since the shapes of the power/torque curves are largely the same as the stock ones. The AWE exhaust in particular looks fantastic.
Your package looks very similar to Mike Sbota's, although his dyno'd somewhere north of 500 hp (for a brief peak). The only differences I can discern are cat-less exhaust and perhaps some machining of the k-24 wheels. Any idea/discussion from AWE about what it would take to make it to 500 hp? I'm wrestling with whether to do a next stage of mods, basically between staying at a "stage 1" level where I am now, adding a Ruf Turbo R package, or adding larger turbos, software, cat bypass (for off-road use only!) from miscellaneous vendors (which would be a lot cheaper than a full Ruf conversion). I sure wish Viperbob lived on the East Coast.
Just trying to collect data.
Again, nice job!

Stephen,
Thanks for the support it is much appreciated.
Mike,
Hope we can get together sometime. If you are heading up to AWE for a dyno run let me know.

Mike,
If you are talking about my avatar that is only a dream machine. All parts are porsche 993GT2. My car looks like yours I think black 993TT. I would also like the front and rear the same as the GT2 one day.

My front GT2 spoiler is at the body shop getting painted, and my GT2 tail with a carbon fiber wing and a large extended wing for the track are on order......
Oh yeah,,,,,,,

OK - Makes sense now - the air dam and rear wing I like costs $75k!

Hey, if any of you guys go back to AWE any time soon, I'd sure like to see what you've done with your cars. I might start "alterations" this coming summer, so first hand exposure is always good motivation.

One question, why does the dyno only read power to 6250rpm, is this deliberate by the operator or is the scale wrong ?
Thanks for sharing.

it is actually a little less then 500 hp at the flywheel. do not forget that power is being lost, therefor to calculate rwhp to fwhp it is 375/.75 not 375 x 1.25.
