I plan on going to PBIR Wedsenday night PBRI dragstrip for test and tune.
I be there early 6 to 6:30. Will do a quick couple of runs.

 

Jerry could you post the dyno result printout for your in house test of the 991 TTS with GMG exhaust. The only thing I've seen with numbers on the forum thus far is the GIAC post. Would be nice to see the results replicated from the dyno video posted earlier with the GMG goodies!

 

Getting this done as soon as I can find a brake kit for the 991TTS to swap out the PCCBs to allow a little smaller wheel (just because I want to get it all done at once).

 

We are lucky to have it a few miles us and only ~3 miles from my shop.

 

Any more information such a Dyno, 60 to 130 and possibly of adding slightly larger turbos?

 

There's a dyno sheet from GIAC on 93 octane on page 1 of the thread. I'm not sure if anyone could chime in with a 60-130, but Karl911 has had some good 1/4 mile results. https://www.6speedonline.com/forums/...ec-qtr-mi.html

We have just completed our upgraded VTG turbos for the 991 so we should be starting testing on those very shortly. Just waiting on our new shop car to arrive from Porsche.

 

Karl911 has the fastest 991 Turbo S in the USA. Besides GIAC stage 2, I believe he has Tubi catless race exhaust, IPD plenum, MPSC2 tires and was running on 100 octane race gas for his record run. I cannot wait to see what numbers mine produces with MPSS and 93 octane. My mods are GIAC stage 2, Europipe exhaust with 100 cell cats, IPD plenum, BMC filter and Champion race Diverter valves. With 100 cell cats vs catless, pump gas vs race gas and standard summer tires as opposed to the super sticky MPSC2s it will not match Karl's but curious to see how much slower.

 

Give to daddy...

 

Did you get any baseline track times before modding, for comparison?

 

Please share with us how you do after you roll your car down track. I'm going with a similar setup and Im interested how you do.

 

No. I got the car and modded it during the terrible New York City winter.

 

Will do. The car will be at Slipstream's Roll Out to Reach Out roll races on April at Pocono Raceway.

 

Just put a couple hundred miles on car after Stage 2. Very happy with results!

 

Just ran the race program w/ 100 oct on stage 2...it's scary. Significantly faster than stage 1 per my butt dyno.

 

Very Awesome! +1 for GIAC. All of my guys are super happy and say the same thing. Enjoy!
