How much HP?

LAVA · 01-18-2015, 01:22 PM

How much HP will the stock tranny, rear end and axles hold before turning into a broken pile of metal shavings and debris?

Tranny about 700, but ur clutch will fail way earlier, then ur differential bushings, then ur half haft axle's, then ur engine about 700hp depends on the tuner, the main axle might fail due to extreme torque ~600, safe bet 600hp n 500lb of torque ur in the green after clutch kit install.

Some 1 correct me if am wrong.

I don't think there are confirmed reports of anything besides engine, clutch, and diff bushings dying...

Someone correct me if I'M wrong, lol

Axles and driveshaft so far are good to around ~900-1000rwhp and torque

The fuse in the drivetrain is the clutch. From what I read and remember. No one yet has broken any drive shafts, axle shafts, diff, or manual tranny gears. To break that stuff. You need traction. Which as most know, the Z has a hard time doing that.

Axle shafts have been broken ~550lb, i remember some one with tt did that and had to swap their pumpkin from a 350z, and it was a girl that sad that. Drive shafts have been popped by some one also with tt mod, manual tranny no, but auto ye also tt.

Thanks for the refresh.

From the number of TT/SC kits installed. It's still very small percentage of those parts breaking. I know the auto tranny is weak in the upper gears.

The type if driving makes a huge difference. Obviously if you are using drag radials or bias plys for hard launches it's gojng to put a lot more stress. I've been thrashing mine for a year at 660hp 590lbft without any problems whatsoever. Oem drivetrain apart from clutch,pp, and fly. But, that's all circuit tracks so there is significantly less stress than drag racing.

My car tore apart the rear end on the track on some 15" street radials. I don't think you could ever get the car to hook hard enough on the street for this to happen.

Someone needs to make a billet diff housing

or at least a brace

A diff brace would be nice. Also help you hook

I've really thought about doing it myself but I can't weld

Tony and Dan need to tackle this once they finish up the G37 TT
