on street tires?? heh good luck with shooting for 11s. a buddy of mine runs 10.9 @ 127 with his cam only t/a with full suspension and dr's. on street tires i think he hit mid-high 11s @ 118-120 and he can drive quite well. (1.49-1.59 60's on the DR's) plus its your first time running it? I'll say low 12s @ 118 mph. not putting you down or anything. hell i could be completely wrong about your times! lol let us know how u make out. when i was on street tires, full weight with a few suspension mods, i was leaving the line between 3800-4500 rpm slipping the clutch quickly and managed a 1.89 60' on street tires. then after the next couple runs, my 10 bolt died lol

Good luck, but it sounds like youre gonna pretty much need to leave off idle to avoid spinning. Practice launching on the street before you head over there, i wouldnt launch over 2k rpms though, but 1500 is prolly about all you'll be able to launch at

Do not do big burn outs on street tires and do not lower the psi.
Drive around the water box and just spin the tires to clean the rocks off.
If you lower the psi or try to do big burn outs on a stock tire it will lose traction potential.
Leave around 2500 and try to keep it from spinning, don't just drop the clutch, try to keep the rpm up and let it out as fast as you can without spinning or bogging and I wouldn't use the n20 till 2nd gear.
Most likely you try to leave at any rpm and hit a shot on a street tire right from the start it'll just spin.
Go do a burn out, spin the tires and roll forward and get out and look at the rubber on the ground it should be even black across the burn out, if the outside is lighter take out a couple psi, if it is lighter in the middle add some air.

we have really similar set ups when i had 370 to the wheels on street tires i would lower the psi to about 26 and leave at 1800 rpms my best times were 12.7 at 112 with 2.1 60's. I went 2 days ago after installing a ls6 and p/p throttle body and smooth bellow the best time i could run on my street tires was 12.9 with 2.2 60's at 115mph so good luck figuring it out on the track
