I was out in my buddy's 07 GT500 yesterday. He made 695rwhp on a dynojet with 410's but then switched to 373's . Given his wheels are identical to mine , taller 20" 305 MT's his rear gear comes in around 3.63. His mods are '13-14 Trinity, stock 2.67 upper pulley, 10% lower pulley, stock elbow , CJ 65 TB, JLT 123CAI, headers, hogged out Cats, MCleod RXT, Magnaflow axle backs. He's running the #56 injectors but given the 07 fuel pumps I wish he had Boost-A-Pumps ! But his tuner said not needed. I used my Visa for his Trinity swap for him to avoid the wifey thing which was not an issue. Geeze...he makes great HP for that combo !
My '13 makes 680rwhp on 410's, same dyno, same wheels so my actual rear gear is more like 3.90's, Trinity with 2.4 upper pulley , BPS O-sized plenum, VMP 67 TB, JLT123CAI, stock lower pulley, headers, Mcleod RXT, Corsa Sport axle backs. Only difference might also be I have an ALFW and the '13 has the CF drive shaft...but seat of the pants cannot measure that.
I'd have no idea how we'd do vs one another because Holy Moly his car is FAST ! My 410's seem a bit quicker on the hit but the thing is I'd approach ANY roll race from a different RPM with my 410's than when I had 373's. In his car 2nd gear needed at least 2800-3000rpm for a quick burst whereas mine would prefer anywhere from 2000-2400 rom with 410's. Same in 3rd gear. At 3500rpm on a roll my car "explodes" in 3rd gear. His car needs closer to 4000rpm and the power build up is a bit different. I thought I'd be able to tell the difference but not as a passenger getting tossed around and even as a driver I hit it 3 times ...2nd/3rd/4th but.....there's so much going on (:->) !
I imagine he's got a better shot out of the hole.....then again....he was rippin them loose no matter where he stabbed 1st gear .
My '13 has the longer 1st gear but no way would I ever stab the pedal in 1st..anywhere on the street. IF I went from the dead I'd turn my TC ON ( it's always off) and pedal it out 2/3 throttle pulling 2nd gear ( no lift) around 5500 before I drop the pedal. Someday this season I'm sure we'll go out and play. That's should be a blast ! I think it would be my advantage to start down low...perhaps 20-25mph as I'd be in 2nd gear in a proven scenario for dead hook. No doubt he'd be in 1st which would likely present a challenge. Both of us power shift and are pretty quick on the stick so that's not to either advantage. Our best exchanges would be from a higher 3rd gear roll....so perhaps it would turn out to be the battle for the " sweet spots! ".
I'm not concerned about top end because I wind out in the 135+ range near 6800rpm......AIN'T NO WAY we're going much faster than that even on a wide open rural road (:->) ! Still Luvin my 410's. But ya never know ! I may have answered my own post....that being there are just too many variables.
But Ya Never know...Not likely cause I've had them before ....but....One race could change my mind back to 373's (:->) !
