That 1.47 60 blows my mind.

I'm going to guess you are going to run some good numbers for sure.
Good luck!

I hate to mention heat since some guys will dispute it or call me a liar.

For me, heatsoak that kills Roush performance is an extremely exaggerated subject. Keep in mind, I live in Minnesota and do not typically drag race in temps over the 80s. My preference, of course is even cooler. Guys in the south will face issues that I do not.

My experience: A WOT pull down the quarter mile adds about 15 additional degrees iat2. By the time I get to the timing shack, it has cooled down to where I began or even cooler. The biggest issue is to keep it cool while waiting in the staging lanes. Shutting the car off adds a helluva lot more heat than running down the strip. An open TB and high speed air through the HE helps offset the heat generated by boost.

In the staging lanes, I keep it running with the fans on and rev it up every few seconds. That is far better than shutting in off....unless there is a major delay of some sort. My 3rd run yesterday was my best. I had the same experience last summer when I ran in the low 80s. I ran just under 128 mph last summer in the 80s compared to just over 129 yesterday in the 60s. ET was better yesterday primarily because the new cal shifts much better than the old one.

I have never felt a performance difference on the street regardless of temps. High humidity seems worse than heat. Hotter ambient temps produce a smaller spread between iat1 and iat2. In cold winter temps, my iat2 will be 50-55 degrees over iat1 just cruising. In hot summer weather, it is 35-40.

Other's experiences may vary but, for me, heat is a non issue for street driving or going to the strip occasionally for fun. If I were racing for points and had to run weekly regardless of temps, I might be more concerned.
My bad for bringing up a touchy subject without doing my research. Good to hear the kit doesn’t really have that Achilles heel after all, at the very least on all but hot days.

Surprised you didn't see in the 9.XX-10.0 with that 60 ft. My 60 ft was a 1.49 and saw a 10.01

1/8 mile strip i did run a 11.1 in the 1/4 mile on that pass according to the dragy but i was on the brakes after the 1/8 mile to turn off on the return road!! (It’s a 1/8th mile track) i dont know if i will run 1/4 mile and if i do ill prob see if i can get the 6-7th gear shift point raised so i dont go into 7th gear on a 1/4 mile pull.

Ended up selling my car at a dealer. Got a better deal than I would have with vroom. Now looking at was originally 2003 lifenfinger zo6 corvette but has no been modded to 700rwhp @ 3200lbs. Only 13k miles.
