Launching techniques for BFG's??
 

I know this question has prolly been asked before and i tried a search to no avail....but anyways im borrowing a friends BFG drag radials on sunday for the track and was just wondering what psi is the best and the best way to launch on them is? im runnin stock rear with a ram clutch and most of the major bolt-ons if that helps any
TIA
