    Stock high 13's. Shoot that nitrous out of the hole, those drag radials and stock stall will not agree with each other. Unless you have a roll bar I think they will boot you out if you get in the 12's.

    Stock stall with nitrous and drag radials will work fine. Did a 175 shot with a friends 98, only change was 3.73 gears and a catback, everything else stock. Ran 1.57-1.58 60 foot times and 11.40's and 50's at 116-117 mph.

    Edit: C5Z28 is on the right track,,,,the rollbar cutoff for a vert is 13.49 or quicker.

    Sadly now demodded :(

    You run better than a 13.50 and they'll give you the boot...

    Ask Larry (Firebirdjones) how he knows this...
