A buddy of mine is running the same Et's and mph in the 1/4 w/ 397 whp NA in an F-body camaro. He is a great driver w/ 1.6 to 1.8 60's.
If you cut your 60's down to 1.6 you should be in the low 11's.
If you have a Z06, then I really think your MPH should have been a good bit higher with that much RWHP and the light weight of the car... I would expect over 125mph easily.

People have gone 118 in stock z06s with ~370rwhp. Don't worry about the mph. If you get the 60' down in the low 1.6's you will run a bottom 11. Tire psi seems too low. I cut a 1.49 with 15 psi in mine. No spin at all, just the tires slipping on the rim.

Its not a bad time, with more traction I think you have 125mph in it.
The traction issues are hurting your mph.
Also the Z06 comes with 3.42s but better tranny gearing ratios than the stock gearbox. I would NOT bother changing the gears at all.
Good clutch and tire and you'll go low 11's at 124-125 easy

Very Nice numbers but IMO the et and mph are alittle off from the hp you posted with the z06 being a pretty light weight car especially with what must have been a minus D.A. last night in NJ.
why run the drag radials that low? what type of DR are you running?
Good luck with the car
Something isn't right-with 413 RWHP in 85 degree heat I ran 122 with a 1.8 short. This is also a Z06. Also I don't powershift either, but with that kind of power u should be running 126-128 regardless of the gears. I know 3.42's are not the perfect gears but with the power and torque your car made u should still trapping much higher.

I believe the tire pressure i was running was way to low & my clutch is slipping pretty bad especially if i go over 5800rpm. im taking the car back to TTP getting a spec stage 3 clutch, hardened output shaft and 3.90's. then it should really rip
