A 991.1 wont come close to 175 with those mods. A 991.2 might hit 170 FBO+meth with a tail wind and low density altitude.
There was one event last year on the East Coast with a heavy tailwind where every category broke a record. That's not normal.
Come to the West Coast where 1/2 mile racing was born and there has been no stock motor 991 over 175.8 mph in the 1/2 mile. Ever.
My car is a 991.2 - and I agree that DA and cooling are critical. I actually felt power falling off just before the 1/2 mile marker. I'm lucky t have done 1/2 and full mile racing since 2013 - and it is my favourite event (although 1/4 will always be my staple). To get into 175+ the car would have to be trapping 145ish MPH in the 1/4 - and I haven't seen that without after market turbos.
Thanks Swole! Now that I have Dragy - I will test again in the fall at the track and see what I put down. I had some rough launches on the tarmac - and I had to use the Sport plus boost to launch as the MPH fell off with a regular sport launch.
As there was no ET tracked - I went for the MPH - but it likely hurt my 60-130. Temps were crazy hot but the car handled them well as had been previously reported. I wanted 160+ which I got - what I don’t know is exactly what the 164/165 runs really were. My guess is high 162 and low 163. I am happy even with a 162 lol.
I saw repeated 262+ Speedo flashes which were about 162 MPH.
Cheers!
Did you compare Sport to Sport Plus , both using the Boost button ?
Nice runs. Over the years I have seen a solid average of about 152 on the .1's and 158 on the .2's in the true 1/2 mile with average conditions. The .2's are just about as quick or a tick under a .1 with exhaust and tune. Race fuel will get you 1-2 as well. Fun stuff!

I did not use Sport Plus T (I stuck with Sport and boost button). With the weather (worrying about and then not getting the evening runs) and the number of cars (100+) - we got two runs each on average. So I had to go with my gut and experience that the aero would not help me out. In fact - I have never used the boost button with Sport plus - ever. Once I understood the full aero would activate for Sport Plus I have stuck with Sport and boost button (or without if no traction) for anything straight line. Interestingly, I DID do a Sport without boost button thinking I would get less wheelspin (which I did) - better ET (10.6's I believe via Dragy) - but my MPH was worse (about 158) - as was my 60-130 (high 7's during the worst of the heat on day 2). I am done with the track until the Fall - and I will in fact try out some of these combinations with Dragy to see what differences they make (and I will share them on Rennlist).

Would race fuel - without a tune make a difference? I was averaging 158-159 in mega heat over the first two days (Dragy verfied). Even my speedo was showing just under 260 KM/hr - which is just over 160 MPH (it was close - like 258). With the temp change on SUnday morning - I was hitting 262+ (visibly anyway) - which is ~162 MPH. No Dragy to back that up unfortunately. THAT said - I am very confident I will be able to Dragy 162(+) MPH on a cool day in the Fall - which I will post here. 163? Maybe - but I am going to go with my butt dyno and say maybe a mid 162. We shall see.
So - I will go on record and say the 2019's are 158-159 (with Sport and boost) on average even with molten temps and dense humid air (high 157's with traction control on - as I did that on one run by accident lol) - with a peak of ~161 MPH. With even somewhat cooler air (maybe low 80's to mid) - 161+ on average. Cool air/great DA peak is somewhere in the mid 162 range for a standing 1/2 mile.
I am hoping someone got some video (especially with the silver 2019 488 I raced - I beat him badly, (launch of course) and (surprisingly) MPH - although only a few MPH. I will post pics here once I have them (they are being processed by the photographers).

Yes, definitely! After a few pulls the car will adapt and adjust for the higher octane. It will pull less timing (or non at all) and be at max timing from factory.

-Payam
Understood - max factory levels - and I would assume some additional cooling. But being on 93/94 octane I wouldn't be too far off. I definitely realize it wouldn’t hurt lol.
Attended VMAX recently with a UK supplied 2018 991.2 turbo s (car 66). It arrived at the same time the turbo s exclusive was being delivered in UK and probably one the last 991.2 turbo s delivered in UK as you couldn't order UK RHD after November 2017.
It was a baking hot and slow day at 33C so starting IATS were at 54C. The trap speeds through quarter mile and half mile and final top speed shows the turbo s stock is definitely putting out more than 580bhp. Top speeds don't lie and the quarter and half mile all pretty consistent too running as quick as Mcl 650s and 600lt both quarter, half mile and final top speed which are lighter and have more power.

Thanks IMI! - great data! The story is that Porsche decided to keep the Exclusive Tune as 991.2’s we’re almost done - plus - they didn’t want tot decertify another tune.
I do believe - that despite the insane heat (we were also 35-+ C plus super dense air humidity) and the car was doing what most other Turbo S cars do in better temps.
Im not too disappointed I didn’t get the data - because I own a Dragy now. I didn’t know it times out - now I do lol.
In the Fall - I hope to find out what the car can really do.
Here you go...quality is poor - and you can't see the finish - but he couldn't gain any ground and I will post his MPH so you can see he was behind their too. Great guy - fun race...
Ferrari 488 GTB has 661 HP at 8000rpm.......poor little 580 HP TTS didn't have a chance......
Lol - thanks T...I was surprised about his MPH. Ferrari 488's are supposed to be mid-high to high 130's in the 1/4? I knew I would smoke him off the launch - I crushed everyone there. But I really thought he would gain in the big end. His best was a 166 (the event number) - which was better than my fastest - but I would have thought it would have been 5 MPH or more better...He averaged all over the place - mid 150's to low 160's. He did say he was trying out settings.He's car 144.
