Timeslip Comparison

Well, i went to thet rack last night to see if i could finish off the clutch. It held up down low and would slip slightly in the upper rpms. I couldn't launch the car hard though either. It would have finished it off on a hard launch easily.

I'm going to compare it to my timeslip from may.

Temp 75 degrees

60ft 1.833
330ft 5.228
1/8 7.9256
mph 89.45

1/4 12.254
mph 115.00


Now from last night

Temp 83 degrees

60ft 2.032
330ft 5.481
1/8 8.208
mph 90.55

1/4 12.474
mph 116.56


The comparison is the 3.12 pulley at 8.8psi(according to the ss box max boost hit) to the 2.87 pulley at 11.5psi(according to the ss box).

I need a clutch and some slicks. LOL

Also met a couple more Z owners there, they are on the board.

With a 1.8 second 60 feet you obviously do not experience any wheel hop. Have you done anything to your rear suspension that prevents wheelhop? I have tried many ways to launch at at the drag strip, however, severe wheel hop limits my 60 feet times to around 2.5 seconds. I have a 2003 Track with stock suspension.

Sounds like you are dropping the clutch...

My technigue is to rev to 3000-3500 and slip the clutch till you fell the car moving. Once the car is moving left of the clutch completely. That has always netted me under a 2.0 60ft(minus clutch slippage).
