On the VQ35HR on 07-up G35 sedan, you'll see 7-8 rwhp, + 10+ ft/lbs of torque. This is with pee water 91 octane. For those of you who have 93 at the pump, you'll see even more.
For you G37 coupe owners with the stroked VQ37HR motor, you should see ~2 more HP and at least 2-3 more ft/lbs of torque. So until I actually test a vehicle, I'll tenatively put the G37 coupe at 9-10 HP, & 12-13 ft/lbs, at the wheel.
Do you think these will make an aftermarket exhaust yeild more HP and TQ than they would with OEM cats?
