When I had the ZZ-4 pump gas engine in the dragster it picked the front wheels up about 3 in. and moved them over to the right just a little, maybe 3-4 in. (still easily driveable) E.T. 5.90 @117. With 2 1/2 times the HP, the problem is much worse
. We only made one very tentative hit before raining out. Checking the tire diameter, I found almost 1/2 in difference in circumference, which equalized by dropping the pressure by 1 psi. Looking forward to this weekend, hoping for more tuning opportunities. Also lowered the wheelie bar (92" long from axle centerline) to 3". Getting the launch dialed in seems like a common thing with these traction monsters. Next time out, it's spin or bleed.
