first time back in like 8 years and need some advice

Performance Results - forums.corvetteforum.com
Took my car to palm beach raceway. Car is a 01z with a cam(224-230) lg 1 3/4 long tubes/ vara ram/ under drive pulley. The car was tuned like 7 years ago and it made 420/400 to the wheels. I took the car to the track once a long time ago, and the best pass out of 3 was [email protected] on a street tire. . About a year ago I replaced the clutch with a mcleod rxt, and installed 3.73 gears and guts from a c6z in my rear diff. So the night before the track, I installed a set of really old et streets on the 17 inch front wheels and decided to change my spark plugs. We tuned the car with TR55, but now I installed tr6?s. I noticed right away with the colder plug, it was not as snappy as usual.

So I went to the track the other night and the best past was [email protected]

Tire pressure was at 17 psi, and I tried to launch at 2500 but it spun or bogged.

What am I doing wrong? I figured this new clutch and gears would of taken me to mid 11?s. I would like to be low 11?s on motor and high 10?s on 100 shot. Any advice would be appreciated. Thanks in advance. Here are the slips , I?m car 4645
