My Renntech E63 S vs Cobb Stage 2 and GIAC Stage 2 991 TTS's!!!
In looking through my videos on YouTube I realized that My Renntech E63 S AMG sedan has roll raced at the same track both my GIAC Stage 2 991 TTS AND a Cobb Stage 2 tuned 991 TTS at Pocono International Speedway albeit on different days. As the videos show my GIAC Stage 2 TTS pulled harder on my E63 S than the Cobb Stage 2 991 TTS.
The first video is my E63 S against a Cobb stage 2 tuned 911 Turbo S with Klein 100 cell catted exhaust.
My RedGutz GIAC Stage 2 991Turbo S (when it had stock intercoolers and Europipe exhaust with 100 cell cats) raced my E63 at slipstream's roll race event in July on the same track - Pocono International Speedway and crushed it even more than the Cobb Stage 2 991 TTS.
This actually demonstrates to me that the GIAC stage 2 car is making more power than the Cobb stage 2 car as my E63 did not change mods. In fact in the race against the Cobb tuned 991 TTS I was carrying my son who weighs 150 pounds. In the race against my GIAC car I was alone in the E63 and yet my GIAC car pulled harder against it than the Cobb car.
In both races I was driving the E63 and driving as hard as it would go.

That's good enough for me, Giac by a couple car lengths over a Cobb, every one out there put the dyno sheets away, and let's see your time slips or videos
This is how we see who is really faster,

That was the 4th back to back run, great weather that day. Overall car was consistent. Did about 10 to 12 runs that day, losing 3 times to 2 997 TTS and a corvette. Mememrable competition was your car, GTR, AMG GT and 991TT with Fabspeed mods. The Fabspeed exhaust sounded very good. Looking forward to removing the 200 cell cats and replacing the stock rims this week. Regardless of the Mods, the 991TTS is a blast to drive.

Slipstream's next roll race at Pocono is Oct 17th (for cars under 750 hp) and Oct 18th (for cars over 750 hp). RedGutz will be there. That weather should be cool and perfect for turbos. Between that and the Champion intercoolers I am not expecting any heat soak issues which hobbled the car's performance so much at Slipstream's July event.
Who won your race with the Fabspeed 991 TTS?

You are going Klein catless exhaust?

I know my Mercedes had to be running slower in the race against the Cobb tuned car because I had a full-size passenger. But I don't know whether the weight of that passenger would make up for the fact that the GIAC car had race gas.

You bring up an excellent point that slipped my mind. In my race with the GIAC stage 2 car I was running MS 109 and the GIAC race tune subfile optimized for race gas. I do not know what kind of gasoline the Cobb tuned car was running. I know that MS 109 and the race gas tube subfile give me the car another 25 to 30 wheel horsepower.

Thanks for the AMG props. It makes for a fantastic and very powerful daily driver with just a tune and some mufflers

It would be interesting to find out if the Cobb car was running back to back. If your 991TTS with stock intercoolers had heat soak issues that day, the Cobb car could have had the same issues if this wasn't his first run.

I will say one thing. The air was a lot cooler during the September 20 meet Than at the slipstream day which was much hotter and in the summer.

Overall the Cobb tune with Kline exhust was consistent from the first run to the last and more importantly was a blast to drive.
Also the 991TT had a Fabspeed piggy back.
