Great to see you over here ! Mine is still on SIEM Cicero, so no empirical data here. One 991.2 data point to consider on 1/2 mile events........the TTS cuts boost starting at 50C for engine protection......since a 1/2 is all about mph and not ET......that’s the main area to correct and is easily correctable.

Good to know about the 50C limit as this event has been historically very hot (40+C temps - so I'm guessing we could test that). Since creating this post - I went through a 991.1 1/2 mile thread and found one guy who confirmed my guess - he said he went 162 MPH in the 1/2(!) which sounds high - but I guess it isn't impossible as I have found it takes an E85 FBO GTR to keep up with the new 991.2 Turbo S - and they should be close to 160 +-.

I don't know if anyone has done 1/2 mile here - and I am hoping someone with some direct experience will let us know.

See you on here I'm sure...when is your delivery?

Hopefully here at the end of March. I hope 50C IAT will be ok in the 1/4 mile pure stock. 28C ambient will probably push 50C at the end of the 1/4. Going on into the 1/2 it will definitely dump boost pure stock. Probably from the 1/4 onward.

That is crappy - it means a lot of cool down - maybe one pass - but likely weakened after the 1/4. Well - I will test that at least.

I've been to many half miles events, ran at 4 last year. In reasonable conditions a stock 991.1 turbo s will do 155 to higher 150s conditions and traction dependent and also event dependent as the timing and more importantly the starting line is not standard either. I think a 991.2 turbo s should be able to do higher 150s to maybe even a low 160 as you have more power up top and should launch better.

Get the traction figured out mainly, the goal is to be able to launch as well as possible and not waste any distance. The better the quarter mile the better the 1/2. My 760whp 991.1 did 178 in good conditions and picked up right around 32mph from quarter trap to half mile speed, id guess a stock one will pick up in the high 20's or so.

Just for how much difference the little stuff makes; I recently rented a c7 z06 from hertz and ran it at the wannagofast half mile event in dallas, first run it did low 150s, by removing the rear spoiler, a can of octane booster ,some tape work and figuring out how to put power down better it went 160 gps by the end of the weekend lol.

Get a dragy if you dont already have one and figure out what the car likes launch wise, also a can of octane booster or race gas will keep the car happy for the whole pull which will be around 17 seconds or so. Spoiler down and lip in. Only theory I never got to test was the shift from 4 to 5, the gearing of 5th with the car shifting at redline seemed to slow it down a little, I think short shift into 5th would also add a mile or so.




ET still matters as you are limited by distance like in the 1/4 mile so the faster you E/T the better the 1/2 mph will be as you are wasting less distance if that makes sense.

Will definitely have some cars out there. I always try it’s just tough with the family. There’s a couple of events every single weekend around the world where I try to support my guys. I always want to be there. I do make it to several year though I miss it.
