Maybe the new converter hits softer like a Hughes?

Looking at video it is defiantly not hitting the tire as hard. But it is faster to the 60ft.

Front too tight and rear needs tightened. I would tighten rear as it bounces up a short way out which then you have all that momentum trying up lift the rear tires of the ground when the power is coming on.



Configuration: 3350#, 582 C.I.,

60 - 1.24
1/8 - 5.53@ 126MPH
1/4 - 8.73@ 159MPH



3700#+210lb driver, FULL interior, through mufflers, 10.5 tire.
60'-1.333 (IN 4000ft DA! Joisy Math excluded; 1.25sec using JOISY MATH.) Wink
1/4 - 9.60@144MPH

When my sprag puked the rpm would drop another 1000 at the shift! Engine bogged like I shifted from 1st to 5th in a manual trans.

Never ran a big tire car, but I have been 8.80 @ 156mph on 29x10.5 Hoosier bias ply slicks at 20 psi, 15x10 rim, no rim screws, no tubes. I honestly don't know why people don't put air in their tires..........

Pictures of my car leaving the line is what led me to keep putting more and more air in them. I have not tried more than 20 psi so I really don't know what the upper limit is!
