You can run no TPMS and you'll be fine. I did that in December and even drove to and from the track on DR's without TPMS, and besides the warning light in the dash, there were no issues!
Nice runs!! Glad to see someone finally preload a little at the line with an automatic! Maybe try a little higher next time out and see what happens.
Don't go beating up on Ls1Lt1..He's actually a knowledgeable, great racer, a long time member and a VERY nice guy. He wasn't attacking you, as proven by his later posts.
Proper skinnies usually -0.1 in ET. Not detracting from your time mind you..And you are right, a 20 minute tire swap and a 10.38 is GREAT off the showroom floor....with better times to come I'd say!
He didn't say he wanted to be on any fast list, and as mentioned above, the way they've been set up is no category for only a 4 tire swap...but that is irrelevant in the OP's performance!

LOL
Thus, there were no sensors functioning. Better?

I'm sure some of the reason is the amount of torque this engine has. Because it is putting out about 600 lb ft. of torque at 3000 rpm it can pull through the initial bite with some authority. Not that torque accelerates the car, but it does allow it to make some decent horsepower down low to get it out of the hole. That same torque will make it a handful to launch well at tracks with less than stellar prep.

I figured that and that's why I mentioned a little too much tire for the converter and track conditions and that a narrower maybe slightly shorter tire would yield a better 60 and put the car in the 1.4x's. Or bump the tire pressure up 1/2 psi until it spins. My only concern is that after 30' out the boost kicks in and wants to break the tires loose. There's definitely a fine balance there. You did a nice job. You veered several feet to the left too on that launch not sure if you yanked the wheel or were aimed slightly left but it didn't look like you were spinning.
Nice going considering all that.

I hate to be that guy. But one of my pet peeves is confusing "quick" with "fast". Fast is a measurement of speed, most commonly used to indicate top speed.. hence the first question commonly asked about sportscar: "How fast will it go?". We all know that due to less downforce, the ZR1 will always be faster than the Z06.. after all the ZR1 has the fastest top speed of any showroom stock Corvette.
Quick on the other hand is a measurement of acceleration. So when referring to times recorded in the 1/4 mile, the measurement is quick. And I completely agree with what you were saying though. I'd just state it differently. If he puts the stock wheels back on and then goes 10.5x or better. Then he will have the QUICKEST showroom stock Corvette of all time!

fast-adj. (faster, fastest)
1. moving or able to move, operate, function, or take effect quickly; quick; swift; rapid.
2.done in comparatively little time; taking a comparatively short time.
When comparing two units of time, it is absolutely acceptable to refer to the faster time as being "fastest." The context of being the "fastest Corvette of all time" has nothing to do with trap speed, and in this case pertains only to comparative ET's.

It would have been interesting to see same day with stock tires how much the skinnies and dr's are worth. Does anyone know what the other fastest times are with stock tires and dr's?
As for the few that mentioned the Viper, well as Nineball will assure you that pedaling a car is a much greater skill challenge and a helluva lot more fun.
If you want to test your skill people run a road course and see what you can do.

I think one of the other automatic guys had also stated that they were able to get it over 2000+ which is awesome news. It might even reduce the need for some people to go with higher stall aftermarket converters (I know a lot of the CTS-V guys retain the stock stall) once they start modifying. And with a complex/seriously computer controlled transmission such as the 8L90, sticking with the factory converter can go a long way at getting it 'dialed in' and also reducing wear/breakage. Ultimately a higher stall will still be needed though for those seeking low 1.4x/1.3x short times.
But if the air/DA is there and you come out with much less fuel (and more 'break in' miles on the car) next time out, it will ET even better.

Probably Hoosiers as I believe only they make that size, plus you can also see the white sidewall lettering (that Hoosier drag radials have) in the video.
Well, in all fairness, he wasn't actually using 'true skinnies' on the front as far as I can tell, just notably smaller/lighter weight wheels/tires that helped for sure, but also didn't exactly reduce ETs or add trap speed by a super crazy amount either.
In fact, if he had run the stock/full size fronts in a slightly lower density altitude or even had a 1/4 tank of fuel instead a nearly full one, he likely still would have matched these results in my opinion.
The next closest stock car on drag radials with stock/full size fronts ran a 10.55@132+mph (on only one single pass attempted on drag radials) but that was in better air but also with a notably worse sixty foot (and likely less fuel on board as well).
Either way, these cars are haulin' the mail in ways some people probably never imagined possible.

A lot of conjecture there...just saying.

However, none of them made 425 HP...maybe 415 HP at the most.

SAE J2723 requires all engines certified to that spec to be within ±2% of rated HP. That means the LT4 can be 637-663 HP.
PS That makes your 675 HP claim BS too...where do you come up with this stuff?
