Im currently researching upgrades for my GTO. I plan on it being a 10 sec car, which may seem like a high goal but its a 2-3 year goal. Anyways, ive been looking at going twin-turbo specifically the APS TT kit. My questions for the fellow forumers is i what goes wrong when you push 700 rwhp in a GTO?
clutch?
Transmission?
Pistons? (looking at 14 psi when all said and done)
MAF? (will scaling it work if it pegs)
drivetrain? (am i going to be breaking axles if i do hook?)
feel free to add other things i missed
its a 2005 ls2 btw.

The clutch will go before anything

That guy made 730rwhp with his OEM GTO motor. I seen alot of GTOs in the 500-600rwhp range with no problems but really have not seen many in the 700rwhp range. One guy I talked to on from LS1 Forum is making 646rwhp on his OEM 2004 GTO motor with a procharger and it has been that way for 15,000 miles with no problems. I would suggest forging the motor and not taking a chance at making that much power. It can be done, but your on borrowed timed. It also all depeneds on your tuner. Good luck

good luck. it's very hard but not impossible to go 10 sec but it will be even harder with a M6. just throwing power at it ain't gonna do it. besides the motor you need serious rubber in the back and you'll have a hard time getting it to fit back there. the IRS makes it a great track/street car but it isn't the best platform for dragging. so... motor mounts, stiffened tranny mount, beefed suspension, clutch, shifter, drive shaft, stubs and axles for starters but a complete rear swap for a solid rear end, wheel tubs and an automatic swap with stall would be the best route. BTW i'd pitch the MAF and go speed density too
