Thread: The BUCK
07-14-2007, 08:12 AM #1
I'll start at the beginning. Last weekend in 90 deg heat I ran a 75.4mph @ 7060 rpm. the ride plate set at 1.030 plate holes not filled, trim tabs shimmed at .120 and it ran flat with no bounce. Looking for more speed shimmed tabs less at .105 and filled plate holes. Went out yesterday 73 deg should be making a little better power still running flat with no bounce until the BUCK almost every time starting 74.5 and up. It didn't happen every time but almost. I did manage to get a couple runs without the Buck a best of 75.8mph @ 7080rpm. I would like to try less shim in the tabs because it was still running flat with no bounce but I have to stop the BUCK.

Standing as far back as I can. Back side of the hump.

Filling the rideplate holes will change the handling, just as raising the trim tabs. Maybe put the tabs back where they were and see how it handles.
Thats damn fast with a 1200 grate.

Thanks I'll give it a try. I would try the 800 grate except where we run its more of a drag race. If you lose the hole shot you lose the race, its not long enough. Around 1/4 mile maybe a little longer, I'll have to check.
PS thanks on the damn fast.

You will have to re-adjust everything for the 800 grate.

7080 is where you want to be.
