So therefore the car is parked for the year untill I get a stronger rear and figure out what I'm going to do for suspension.
    We get the best on those 18's running 19-17.5 depending on what springs or air bag press.
    12 psi. is way to low!!! If you were to go to a nice cement parking lot and do some holeshots you would see that the edges are going to be WAY darker than the center of the tire.
    You need to have enough press to keep a nice square tread pattern on the track!!
    Sorry to hear about your gear........You mentioned it was the end of the season thats one of the biggest reasons I moved out here to AZ we race year round.
    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    I guess it would be cool to live where you can always cruise and race. I look at it this way though, If the car is broke during the winter it's no rush to fix it nor does it bother me being broke. This past summer I got so mad because I just did the cam and a bunch of other work and the first time to the strip I broke my gears and tranny. So it was a mad dash to get parts as soon as possible and more money I wasn't expecting to spend for the season.

    thanks for the advice on my tire pressure. I still have plenty of tire left for next season to try that out.

    No problem.....Also if I was you put your wheels in the basement for the winter it will keep them soft and sticky for next spring..... I found that the freezing and thawing make them almost as bad as sitting in the sun for some reason.

    Right now they are on the car out in the garage. The garage is pretty well heated so it shouldn't be too hard on the tires.

    I have gone 11.73 @ 117 with a 1.7x 60' letting off to get the tranny to shift into 3rd (drive).

    I buddy of mine has the same tires on his camaro and I think he said he pulled a 1.7 60' with around 12psi. The only thing is his is auto and stock stall. But I'm pretty sure he sprays off the line.

    God, that is VERY low pressure psi for that type of "rubberband" side wall dragradial. On the 17" and 18" we have NEVER had any luck with anything under 16.5psi. Then again you would be amased at how in accurate the cheap guages are atb that low of tire pressure also.

    The only way I could see that being optimum psi would be if you had a 325 on a 8.5"-9" rim where the side wall is balloned because the tire is wider than the wheel....... When you run that low your not getting full width tread contact bwith the track. All the weight is on the edges of the tread.

    That does make sense. Maybe his gauge is off. I sure as hell know that all I do is spin with that pressure. My intensions are to get a set of Welds for the car, but for now I'll have to make do with what I got. If I can hook that's all that matters.

    Yeah unless you have a Low TQ. # the Nitto's SPIN!!!!!!
    IT JUST DEPENDS ON WHAT YOUR INTENSIONS ARE........ Are you trying to hook up horsepower or get milage out of a "Drag Radial's"........... The Nitto's are NO comparsion to the MickeyThompsons!!!!!!

    I thought if the Nitto's hook and the tread last longer I may as well get them. I don't think Mickey Thompson makes 18" drag radials. Not sure if I want to use my old 16" wheels with them or not, the biggest drag radial I found was only like a 255-50-16 or something like that. I had the car tuned on a hot and humid 90 degree day. My #'s were 412hp and 368 tq so hopefully that will improve on a mild day. Hoping an electric water pump and 160 stat help out a little.

    That was almost my exact run on my Gtech RR last night. 12.704@117.99. 60' was 2.298. Bald Falkens (275s) on cold roads. I need new tires! Good to know that if I can learn to drive I should be close to 11s.

    It stinks having crappy 60' because getting that down will mean a big difference in the 1320. What mods you got done?

    When my car was bone stock(cut off muffler only mod and k&n)and stock wheels and tires. I ran a 13.99 at 106 or 108mph not sure off the top of my head, but I know my 60' was a 2.4.

    I have a Vararam intake, Shaner ported/polished T/B, LS6 intake manifold, G1 cam, Kooks L/T headers with high flow cats, Z06 Ti exhaust. Car put down 381 RWHP before the Ti exhaust, Vararam and throttle body. Need another tune but I am hoping for 400 RWHP, adding those mods my traps went from 112-113 to 116-117.99. I really need to hit the track but closest one is 2.5 hours away in Seguin.

    I think it would be a good idea to get some sort of drag tire.Otherwise I think you might waste your time going on street tires. Just my opinion though.
