I'll get there... I know the car's got it in her, but just not today. Until then I'll happily take Philly's title for the fastest f-type on motor, and by a whole 0.01 seconds. These last 3 runs of the day, I had 4 wheel spin off the line, killing my 60'.
It is interesting comparing your runs with my fastest. You are travelling faster by 5 or 6 miles an hour at the 1/8 mile mark and get there 0.4 seconds quicker but we have similar speeds at the 1/4 mile so mine must get a bit of a spurt on in the second quarter.
I presume that is down to your AWD but I wonder if my terminal speed would improve with drag radials or AWD or just get there quicker?
What tyres are you running?
Sounds like you need some drag radials, slicks or similar.
Or are they not allowed in your class?
PS4S; I've never had any issues with wheelspin before, so i'm assuming track prep wasn't the best later in the evening. It's not the best facility in the world. Given that i'm AWD and only go to the strip once a year, drag radials aren't very realistic for me.

I've always been on the low side of the MPH conversation compared to what everyone else is at for the same ET. For example, when I was running 11.6 stock, that was just at 121 mph. Could just be my sub-par drag strip, I always use the same one, or it could be the car. Who knows... that being said 126.25 = 640 bhp, which is about right considering my mods. Drag radials would definitely help your 60' time, because that's certainly something that could be improved.
Its the tires for sure. I ran street all season radials at an 11.3 at 128.25 mph in the quarter. Tires just didnt hook up off the line. Anyways, I smoked a Ford Shelby in the first run and a BMW M3 the second run. They had track tires too.

Very nice! Congrats! Those are excellent times and the best I've seen for an F-Type R without nitrous. Setting the bar very high! I now have a challenge ahead of me to try and best that! Might have to wait until better temps outside. It's hot and humid here.

Tell me about it; we've been in the high 80s/low 90s with 50%+ humidity for weeks. I was just lucky one of the two 75 degree days just happened to fall on a test and tune day; maybe I'll try again in the fall.
After testing with dragy on a hot day, I’m sure my car has a 10 second pass in it after my recent Dragy time of 11.19 at 126.33. I was only cutting 1.8 sec 60ft times and I’ve done 1.65 np. With cool weather I also have more top end. Fingers Crossed! Let’s see who gets proper weather first and that might be it!

0.2' is a pretty substantial amount of time to make up, but I wish you the best of luck! I'd like to see what you run at a real strip though; i'm not sure I trust the accuracy of those Dragys. Plus, you know... the road isn't flat.

Tune, lower pulley, colder plugs and tires. I must be on my 18th tune revision as well...

Yea will be going to the drag strip in September! I’ve got a couple of tricks up my sleeve 😅

wow 18th version... why and is it a velocity tune?

18 might be an exaggeration, but it's a lot. Some based on my requests, but mainly just continuous improvement. I've been working with VAP for years now, and they typically send me new files when they've learned something new tuning someone else's car. I have over 20 files, though I haven't used them all.

INTERESTING! Chris is an awesome guy. I suppose we are all benefiting from both your work. I went through 2 files myself for the stage 2. I wish I could data log for Chris. Thank you!

did you notice any difference with the colder plugs?
I’m also on a VAP lower pulley and tune that I installed about a year ago. I wonder if there is an improved tune from the one I have now. It drives great, and I have no complaints though.

I installed the colder plugs at the same time I did the lower pulley, so I can't say I experienced the car without them. I wouldn't expect any seat of the pants difference, but Chris may very well have separate tunes based on whether you were running colder plugs or not. In my opinion it's a requirement of the tune/pulley combo because you're now running outside the stock plugs effective operating range from a horsepower standpoint.
Great job and you will get there!
I have a VAP tune and lower pulley but have never got any addition tunes?
I see you requested some from Chris?
Maybe I can get an updated tune if things have changed?

Great info.! And I do plan on getting a real tune and lower pulley as I get closer to end of warranty (assuming I can wait ) . I run 1 heat range colder Denso Iridium in my 997 TT tuned and also gapped way down for the additional boost pressure to maintain spark.
Also, some of these plug companies get crazy with numbering for heat ranges and they are sometimes backwards. Would you mind sharing what plug (incl. the heat range) and gap you are using with the VAP tune? Will keep it for when needed.

They had track tires too.
