got back to the track tonight (only night off from work this week). got there early while there were few cars there. i got about 6 runs in a 30min period. i was having very bad wheel hop problems all the way down the track using my bfg 235/60/15 drag radials on maxima wheels. i was running 20psi with lean afr's with race gas estimating a decent 400rwhp/torque. seems like these tires jsut cant hold that much even at low pressures.
the last run a simple 12.7 had wheel hop right before the traps in 4th gear at 110mph (peak torque) so i went to put it into 5th to get rid of the wheel hop and there was no longer a 5th after that. my 5th is basically neutral now. other gears work fine.
so as a heads up the bfg 235/60/15 are good to about 350 maybe even 375ish rwhp. dont plan on using them in a 400hp car. these will probably be for sale soon
