Default Limits of a 12 Bolt

What do you think the hp and torque limits of a twelve bolt behind a six speed and 3300-3400 car would be? Specifically a 12 bolt with a spool, 33 spline axles, and a solid collar.

This is the reply that I recieved from Moser. Do you guys know of anybody running more then this with a 12 bolt and a six speed.

Hello,

Our 12 Bolt is designed to hold up to 1,000 HP.
If you are already going to be around 1,000 HP starting out , I would go with a 9" Bolt-in instead.

Thank you,

A spool will help it live longer... the posi would be the weakest link if you went that route.

So far so good with mine...

I have yet to ride in a spooled car on the street. I am curious, because I know with what I have planned, my posi will be toast eventually.
