Well I got only 3 runs in since they were having bracket races all day and I had to wait till they had time in between for time trails. First run I had the DR's set at 18psi cold, and launched easy (1100-1200 rpm's) just to get a feel for how the truck behaves with DR's. DA was 1451 feet, 3/4 tank gas.
60ft - 1.960
1/8th mile et - 8.393
1/8th mile trap - 83.97mph
1000ft - 10.917
1/4 mile et - 13.050
1/4 mile trap - 106.28mph
Second run I messed up on the launch and third run I spun hard to a 2.027 60ft. Went back and checked the DR's tire pressure and it was at 22 psi, which is probably why I spun so hard last pass. Not proud of the times but with the DA corrected my 13.050 time turns to a [email protected] so the mph is there, I just have to get my 60ft down. Next weekend I'll get another shot at it if the weather holds out.
Gotta play around with the tire psi and launch rpm and find that sweet spot. What are the QC's setting the m/h drag radials to for psi, and are you guys getting better 60ft's from launching low rpm and flashing the TC or just leaving at 1800-2000 rpm? IIRC the m/h's are suggested to run 17-22psi, but I'm wondering if I cold go down to 15 psi wthout spinning the tire off the rim.
