This will be a good list. I am sure that there is something to be learned by it. For example, I am not sure that I have enough rwhp to get a much better 60' than I have (just my theory) but I don't know what could be added to the list to let us learn more. TC = Yes or No might be something to add. 1.96 - Goodyear F1 Supercar - 255/45/20 1.81 - Hoosier DOT Drag Radial - 275/40/17 I now have a set of MT ET Street DRs and M&H RaceMasters, both in 17" but I won't be able to try them until spring.
What PSI.... I added that to the list 15psi. But keep in mind that when using DR's, the PSI will change dependent on weather, elevation, track prep, ect... I have cut 1.8x 60' here in ABQ using 13 psi. Individuals will need to conduct trial and errors to see where the sweet spot is. Rule of thumb should start at 18psi and go down from there. NEVER go below 13PSI on DR's. Actually, 15PSI should be the lowest for new comers until a feel for the low air pressure is obtained. IMO
RT w/ 2.82 Gears Hoosier 275 40 17's @ 23psi 1.69 best avg 1.73 Pro Torque TC (Heads and Cam Midlength Headres Added) #4250 BFG DR 265 45 18's @ 25psi 1.83 Best avg 1.87 Pro Torque TC ( Bolt ons No H/C ) #4250 Stock Conties @ 37psi 1.95 Pro Torque TC ( Super Chips, Gibsons, Zoomers, Ram Air Voliant) #4400 Really 60's will say more about the driver and trackprep than the tires ability to hook. -R
MSRT8.......1.78 60' on RSA's converter,comp 268. 1.63 60' on DR's Charger R/T w/ DR's 1.93......Stock motor and converter.
Ah....want pressures too huh......ok.....RSA's 24psi.........DR's on the SRt WERE m&h 275/50/17 and had 28psi..........the tires on the Charger were MT 26x11.50 Bias Plys and had 23psi.
RSA's 245/40/20 on SRT8, 23 psi rear, 33 psi front, best of 1.96 while mostly stock Vredestein 275/40/20 on same car w/ cam/heads/TC, same psi, best of 1.91
