T-bars vs Stored energy

So it's not coming up fast enough.

The 340 comment was about the bars. I would not put 340 bars in it.

Have you cut the upper bump stops. If the car tops out on the stops,it will essentially KILL any further transfer.

Clamp the crap out of the front segments. Take all but one clamp off the rear

17# in a drag radial on that car is WAY too low. You're killing the sidewall. The sidewall rebounding and poor shock control are likely causing a lot of the issues with the hop as well.

SS springs, rancho 9 ways, 275's at 23#... 1.43-1.45 60's
My friends Cuda goes 1.40's with 275's at 20-22# It's goes 1.34-1.36 on a slick

This car went 1.47 with 20-22# IIRC.
