I just purchased a 2014 turbo s with 8500 miles .
took it to the track and ran a 11.34 @ 124mph with 99mph in the 1/8
it spun out of the hole but I still think the mph is a little off . The car is bone stock and I only see a high a 16psi of boost . And sometimes slightly lower . Runs are in sport plus and running 93 octane fuel .
I thought I should see between 17.5 and 19.5 psi on average . Any info is appreciated.
I have also made some 3rd gear pulls on highway and still haven’t seen any higher boost .

 

What was your 60 ft. times on those passes?
What was the weather like / Did you test the DA?
I assume it was fairly cool out and a good DA.

Seems your 11.34 is close also, given the spinning. I'm guessing your 60 fts. were in the 1.65-1.80 range. The spinning actually helps the mph a bit on the back end though.
The 99 mph 1/8 seems strong, maybe it pulled some timing for the back half. Mine also ran a 98 mph and a 99 mph 1/8 (the same 10.96 pass)


My 997.2 TTS with stock tune ran a best of 10.96 @124.1 in fairly hot / humid conditions. That was due to my awesome 60 ft. though. A 1.55 60ft.
Only mod is a Europipe exhaust, but they say the ECU want let you take advantage of the exhaust without tuning it.
997.2 TTS has larger turbos than the 991.1TTS', so your 124 mph might not be too far off.


If it was good dry weather and cool dense air, I'd say you might have someone do a boost leak test, as I'd figure the 991.1 TTS' should trap closer to 125-126 in that weather. But, your car could simply just be a 124 car. Tune it and you'll see a pretty big increase. Oh, at BUY A EUROPIPE!!! Best exhaust out there.

I'm ONLY running the Cobb OTS Stg. 2 93 octane tune and the Europipe and my best ET / Trap at the track (Hot / Humid Summer time) was a 10.78 @ 127.28 with a 1.55 60Ft.....BUT, in cool / dry air with only a 400 DA, on my Dragy, my car did a 10.77 @132.6 MPH with a HORRIBLE 60 ft. of 1.86 (Spinning badly).


I gapped and beat a 2019 ZR1 and still had time to get on the brakes to try not to break out of the 11.00 Index class (hence the 120 mph trap.
Did a 2.88 zero-60 on NO Roll out and that was a 2.67 Zero - 60 with the one foot roll out.

 

Sixty foot was a 1.81 and it was nice cool day temps around 45 degrees .
thanks for the info . Nice runs awesome videos

 

Thanks!

Yeah, your 1.8 60ft. hurt your ET. on a track with a better 60, and you'd be in the high 10's for sure. I think if you do have a boost leak, it'll be very small. I think you're making good HP.

If you take the weight of a 991.1 TTS plus you as a driver ( I used 200 lbs.) and put it into an HP Calculator with your ET & Trap, it came out to 556 HP. I think you're good.
