Hmmmm, we need to figure out why you are not getting good traction. Maybe front brake line lock for a decent burnout?

One more thing Jon. When your car was on the dyno you could hear the exhaust struggling to exit. A couple of people commented on it including the dyno owner. So yes, I bet you picked up a good amount of power and that was reflected in your mph.

Burnouts are not a problem, I usually lay into them pretty hard and wait until I see a good amount of smoke before I pull out of the burnout box. My first burnout might have been a little weak but the 2nd and 3rd should have been more than enough.

The tires are few years old so maybe they're not as good as they once were?

Then again my posi has nearly 140,xxx miles on it so maybe it is giving up a tad?

It always leaves two stripes on the street but maybe the stickier tires are too much for it to handle. Should my suspension/tire combination be able to easily provide traction for the amount of power the motor is putting out?

Don can put your car on the rack and check the pose pretty quick. Mine failed the test and had to be fixed. I gave him a punch of posi-shims that were ordered for my car. We just need to get you squared away for the Invasion. I think a bunch of us are going to show the 4th Gens how it is done at the track.
