Wheel hop on dyno? (Long) I have a 01 M6 Z-28 that i dynoed the other day. Only problem is my dyno graph looks like a two year old drew it. It has a constant wave to it, because my car started bouncing. I have 40,000 miles on my stock shocks, LG lowering springs, BMR adj panhard rod, BMR adj control arms, BMR relocation brackets. What I think is happening is when the 150shot of juice is hitting it's bottoming out my shocks, hence the bouncing of it coming up and the juice forcing it back down... like too quick of rebound? Perhaps springs too hard? Is this possible? All opinions appreciated.... and will send dyno video to you if need to help analaysis. I would have tried it on a lower shot to see if the same thing happened, but I blew the output shaft seal from the bouncing. It doesn't bounce on the motor runs, which makes me think the suspension thing.... cause motor comes on gradual.
