I made a few rear suspension changes over the winter. Also did some wiring clean up and a race column. Recording some data now as well. Hoosier DBR 28x10.5's at 16PSI. Recommended by the manufacturer to start with.
Some observations. The Chevelle will be quicker with the changes.The radials are moving. I believe the car is out of pump, at least I feel like it is laying over and breaking up at the top is a fueling issue? Did have a new best 60' and 330'.
The Fuel Pump is a Quick Fuel 230 GPH @ 7PSI. Probably need to go with race pump like the MagnaFuel 4601? Open to suggestions?
DA for the day 2,500 to 3,000". 85* and a little humid. Really nice day for some testing.
TNT night and busy with Street Cars and Some Fast Hotrods.
Spun on this pass. 3,800 on the 2 Step. I've watched it in slow motion a few times. From the audio, it seems to spin after the hit with the front tires up. Feel like this burnout was light. Might have been the reason combined with the higher RPM leave.
Getting used to the new Tachometer. Shifted way late on this. 7,500. Car MPH's best at 6,800 low to high. This is the best 60' and 330' the car has ever been. It also ties the best ET. It was 5 MPH off from the previous best of 2019, late shift and breaking up also got out of throttle early. The car with slicks would pick up numbers in the 60' as the 2 step is increased. I feel it will go into the 1.2's with tuning.
1.31/3.75/5.87, 3,600 on the 2 Step.
First pass of 2020. 3,300 on the 2 Step. Shift was 7,300 I believe on this. Also breaking up a little.
This is how much both tires move, 2 passes. Both sides about the same. I did Hi Tack the beads. Should I bite the bullet and go to beadlocks? Seems like excessive moving? I feel it's a safety issue.
