Ok let me stat by telling you it is veary easy to blow your motor off of a 75 shot.
i also have a 6 gen and blew my motor after about 1 month. i had a NOS single fogger 75 shot with all the propper fuel and ignition upgrades. i dyno tuned the car and everything. i was putting down 197whp and 235 torque. my a/r was really rich so we droped fuel pressure 5lbs and went up one nitrous jet. i was still rich.we could of kept on making more power but i had no internal upgrades.
my motor blew not to long after.but my best time was 14.5@98mph.if i was you i wont even put NOS on that motor.
my motor only had 35000 miles on it.
