New Wheels No go!

[ConElite]

So I Proceed to get my car ready to go race this past thursday (Last night).
Wednesday I changed the oil, Weight reduction, Removed End Link from Front SB, And Cleaned air filter and TB.

I also put My new Wheels on the car. So Last night I went to the track. I set the tires at around 28psi (hot) and go into the water box. Heat them up for about 3 seconds, nothing amazing and stage. I launched at around 2300 and "BOG!!" I run an 8.9 with a 2.2 60'. So Next run I lower the psi to 25 and launch at 2600rpms. "BOG!!!" with a 2.17 60' and a 9.0 ET (Forgot to turn off the A/C). At this point Im mad and go up for the last run. Sit there and heat them up "Well" and launch at about 3100rpms and cut a 2.0 60' yet a 8.8 ET. I was having some serious trouble launching (first time on new Wheel/tire set-up) and shifts were not as fast as possible do to the POS clutch thats in it. I say would a lot more practice and the new LS7 clutch, and a 3400rpm clutch dump and PowerShifts I should redeem myself.

No it was just the 8th. i dont plan on doing to much mods so im sure my rear should be fine. i have a hand full of buddies running 11's with their stock 10 bolt. all im looking for is 12's and thats it.. high twelves.

Way too much pressure for ET Streets. Drop them down to 16psi next time. What diameter are the tires.... 26" or 28"?

I agree, way too much pressure. I usually end up getting down to about 12 psi, launching at 3 grand with the 4.11s in the rear. I still spin a little. Might be time for some screws in the rims (so I can go below 10psi)

I dont think its to much pressure If I was still bogging. From My Understanding you want just a little tire spin but still be gripping. I have 26" tall tires.

With that much tire, and your power level, you need to do a huge clutch dump, and let the sidewalls absorb the initial shock. Try lower tire pressure (soft sidewalls), a very short burnout (a little less "sticky"), and as much RPM as you think the rear end will handle (ouch!). That's the problem with the M6 and a 10-bolt.... hard to get it out of the hole.
