I was thinking about this. How much power can the rear differential hold? What part of the drivetrain will go out (excluding the clutch)? Would the driveshaft snap, or would the differential simply be ripped to pieces?

 

The tranny would probably be the weakest link, but it depends on how you drive the car, as well as what kind of traction you are getting. There are guys with V8 FCs making 500 + HP/TQ, using an N/A rear end. They are fine when using normal, smaller tires. The second they would try to run a slick or a wider/sticker street tire, that thing would expload in a second. The N/A transmission is rumored to not be good at much over 250HP.

 

Darn, only 250? I use 8" wide tires that are generally about .8 inches taller than stock tires. I hope that it can handle 250 at least. I was originally hoping for 300 at the most... Oh well, more incentive to run a complete TII driveline with the 5-lug hubs and all, I guess...

On top of that, how much RWHP would I need to get into the 13s? Assume that I'm a decent driver.
