leaving with no boost but 6000 ish rpms i would net 1.65-1.66 with a 5.3 at 18psi in tires

14-15 range netted high 1.7s
16-17 range netted low 1.7s
when i stayed 17.5-18.5 it was consistant at 1.65-1.66 for most tracks i ran at


ran same tires on my lightning with stock stall, stock suspension and no traction bars netted 1.72s at 18psi this was leaving slightly above idle with stock Eaton

 

Is this truck 2wd or 4wd? 1.7x 60' is leaving a ton on the table in terms of 1/4 mile time.

 

2wd truck

 

ill agree with George C I'm running same tires and 18LBS to 20LBS is were they like to be anything lower then that it wouldn't 60ft as good

 

Well guys I'm going to set them 19lb cold and do a small burn out and let them eat.

 

I seem to do best at 16 psi as well, but I am running 16" rubber

 

The compound on these specific Hoosiers need to be ran higher

 

large range of pressures... thats fine. try them all man and let us know what works for you

 

18psi seems to be the magic number for me with a 28/10.5/16 Hoosier on 9.5" wheel. When I had them on the 7" wide stockers I had to run lower pressure for the footprint but they would sway bad on topend.

 

bingo!! the 17s have a softer compound then the 15s and the 16s

i was cutting 1.6 60ft with 20lbs
