horrible times with 422

[Wango Tango]

I went to track yesterday after getting my 422 in. I had 5 disappointing runs. It was very easy to miss a gear, so I had to really slow down my shifts.

In my trans am, i had a ripper and a drill mod, and could WING them into gear, very fast. In my zo6, I have a ripper also, no drill mod (I was told you cant do them on a zo6?), and cannot shift near as fast.

How can I speed up my shifts?

Best run was 2.0 60' 11.8ish @ 124

It supposedly dyno'd 475/466 and that was a not a full throttle run supposedly (?). Even so...475 rwhp in a zo6 should = higher than 124.

How much mph am I leaving on the table? That is slow as hell for what the car is, IMO.

with that much torque i would say 127 is about right depending on conditions.

what gears do you have?

[Wango Tango]

I have the 3.42 with of course the M12.

Are shifts slower on y bods than f bods? I could really nail my t/a.

[2002Z06Yellow]

shifting cant be that much worse on these cars. 3.42 are probably holding you down, you could benefit from a quicker 3rd and 4th. you probably shit into 4th and before getting towards the 5000RPM range the race ends.

Wango-No experience with the Ripper but the Hurst shifter in my Z06 is a winner! It has a very short throw with a tight pattern. With a little practice you can make extremely fast upshifts, and it is hard to miss a gear. Some of the other aftermarket shifters may be just as good, but I know the Hurst shifter works well. If the Hurst does not help, you may consider looking for a problem with the clutch. The clutches in these cars are a source of problems especially with a modded motor, and hard use. Do a seach on Z06vette for clutch problems before giving up on the Ripper.

according HP CALCULATOR you making 507hp at the weight of 3400 pounds, so i say you are almmost at the max mph.

You should be trapping higher in general but alot of factors come into play regarding mph. Including: weather,shifting,60',wheelspin. So, if your new to your car that's probably right until you get it dialed in. Goodluck.

I noticed some rattling too, which I thought was my shifter. Upon ataping, it was ~ .770-.780...which obviously is lean. The noise could have been detonation. However, nothing showed up on knock sensor, and the plugs looked good.
