Re: Wheel Hop (LingenfelterC5)
Doesnt that slow me down in the track ?
It would be nice if they were designed not to wheelhop from the factory.
Here is the info...
"The Power Hop algorithm is used on manual transmission Corvettes,
only." John Juriga states. "If TCS (traction control system) is turned
off, it is possible to get the tires to break loose and have axle hop,
or oscillate, during hard launches. To remedy this, the TCS module
requests a torque reduction from the ECM, even though TCS has been
turned off by the driver. For Power Hop, spark and/or fuel (reductions
are) used rather than throttle to improve response time. This request is
calibrated so wheel hop can be reduced as much as possible without
compromising vehicle performance. The TCS module requests just enough
torque reduction for just long enough to get the axle back on the ground
during these launch events."

actually, the uncontrolled wheel hop would slow you down as it would continue on until you let off of the gas......with the algo, you can keep your foot planted and let the computer get it under control...it works, I've used it on a poorly prepped track.....
BTW,
good post Tom... :cheers:

Give this a try- lower the back of the Z06 1/2-3/4 inches and have a good 4 wheel alignment done. I was told it will help greatly as it aids in the weight transfer on a hard launch. The Z06's seem prone to the alignment getting "knocked" out. I'm going to do this to my 2001 with pretty severe wheel hop at this point.

Anyone know if someplace sells something to eliminate wheel hop?

Re: Wheel Hop (LingenfelterC5)
I was the king of wheel hop. I had it so bad the "driver abuse" algorithm would engage on launch as well as the 1-2 and 2-3 shift (power or speed shifting). When the algorithm takes over it is like you hit the brakes, so yes it kills your times, but in theory saves wear and tear on the suspension.
I replaced the rear bushings with poly U bushings and reduced wheel hop by 90%. You can try slipping the clutch more, driving easier etc. but most of those things will cost you E.T., I prefered to attact the root cause. Drag shocks might have helped too but I didn't want to take away from the road race handling capabilities of the car.
Just my .02.
