rear end
400 h.p. v8 w c4trans 28x15x10 tire 3000 launch r.p.m will the stock rear end survive ? 83 rx7

not too long. it is drum or disc? i guess a lot would have to depend on current condidtion and how well it had been taken care of in the past. it might hold for a little while.

Hmm....the horsepower isn't the problem, buddy---the torque is. If you're launching at 3000rpm, you are RIGHT in the powerband for maximum torque----on a stock Rx-7 that's made to handle less than 1/4 the horsepower and disgustingly less torque.
I wouldn't worry about your rear end, God knows that won't hold up. I would worry about your driveshaft making your car a martyr machine. :) ~Jerry |
It will last long enough to get you to the starting line, enjoy the tow home.

Just read your post again, I say you'll be lucky if you manage to even warm up the tires without blowing the rear end. |
My stock SE rearend has held up very well,but I attribute that to a fair bit of lowend turbo lag.And I dont beat it......
The stock rearend is reasonably tough,but yea they arent made for crushing lowend torque launches.Start looking for a Ford 8.8" rearend. |
