Default 1/4 mile MPH

My 60ft isn't great due to traction and stock tires. My speed at the end of the 1/4 is from 117-119mph. My question is what times would my car be capable of with these trap speeds. I know a lot of variables you have to take into account but just seeing if anyone had an idea. Thanks

I am guessing 12.0-12.4. I know that the better 60' times will give you higher mph.

Yes it does. Reason I was asking was to see if there was room for improvement on my part. Wasn't sure if that was good for a high 11 second pass or something. My goal was to break into 11's.

Thanks. I guess I'm doing ok then. My best was 12.2 with street tires and 100shot of nitrous. My goal was 11.9

My 60ft needs to improve. My best 60ft was 1.7 and isn't consistant with each run.

Actually, I'm pretty impressed with a 1.7 on stock tires, since most people are in the 2.0 or slower range. However, still not in the 11's with that 60', does make me question if the nitrous is working well.

Like HOXXOH mentioned, that's actually a very good 60-foot for street tires.

Get some nice drag radials and that should help with consistancy a bit.

With a 100hp shot of nitrous, traps should be 124+... even if you were hitting it after you got traction.

117mph is pretty much a bone stock C6, I believe...given average density altitude.

My car is a 12.4 car with a tune and CAI, only 115mph ... I forget my 60ft
It seems like you may be having issues with the shot.. I would think with the shot you should be doing better than what you are ...

In my old ls2 c6 I went 11.66 at 118 with just longtubes an intake and mail in tune. So 11's are definitely doable if you can get that 60' down.

1.7 was a one time best for me. I'm pretty much in 2.0-2.2 60ft. I only have about 25 passes with the car. my nitrous controller is set to engage in 2nd gear and 2500rpm or above and cut out at 6k rpm. By the time I shift into 2nd Im pretty much grabbing 3rd.
I can def tell the difference with the nitrous on or off but my times don't show it that much.
I can run with the nitrous off and make 12.7 - 13.2 passes. I definitely need some good tires but I'm hoping it's just driver error and need for improvement. I also run in competitive driving mode rather than traction control off. My passes seem better with it in competitive driving mode.

Thats a nice time. Was that with street tires or slicks? Also are you M6 or Auto?

Would you assume that if I ran a 2.0 60' that I should still be into the 11's?

Probably not NA. But probably yes with nitrous.

I ran 1.9's bone stock with a best of 12.41@ 117+. I also ran 1.9's with minimal mods at 11.9's @ 119+ all on street tires. With more mods I managed 11.4's @ 123+ on a 1.75 60' and still on street tires.

That just tells you, that the 60' time is important, but also that after the 60' makes a lot of difference too. The wife's Caddy V6 runs 2.1's, but only 14.9's @ 96. It's a good start and a poor finish.

If you did 12.2 with street tires, I say a smaller lighter 17" drag radial set-up with a 275/40R17 and go there with no more than a 1/4 tank of gas 11 is all yours. pull the passenger seat out if you have to it made a difference for me. think it weighs 53lbs and I'm already 230ish lol

Are you M6 or auto? What RPM where you launching at with street tires?
