How much HP can a Stock rear-end handle??

[bob331T76]

Question is how much HP/TQ can a stock fox body rear-end handle before letting go. Im putting down about 345rwhp 355tq. thanks bob

it can handle that much power, what you need to worry about is with traction what will happen. a friend of mine makes 250hp 290tq but he had alot of suspension work and he is running HUGE mt drag radials and he spun one of his axle tubes.

i believe i have to make 425 ponies on my juice to do the time i do in the 1/4 mile. after 5 years i snapped a axle in half. just replaced it with a used one and i was good to go.

sweet thats good to hear for now i geuss ....looks like i wont be squeezing then until i build the rear..... once that is done tho, here i come hellion

you should be fine for a while at least. I myself plan on going with a 9" with 35 spline axels myself...when the time comes

I have gone 12's in the 1/4 and high 7's in the eighth on my 7.5 in axle, 4.10's and SVO traction lock. Includes a few sprayed launches, but still high 1.8 sixty foots.

A lot of it has to do with how violently you want to launch. A stick car on Drag Radials, MT's or slicks will most likely break something quickly with hard launches and shifts.

I am headed to 31 spline axles, and c-clip eliminators in my new 8.8 as soon as I can get there.

Hey Rd I have an 82 GT. What all did you do to your motor to get those times. Did you use the stock block and pistons. Just change the top end or what. I am looking for some upgrades to do to the car. I put a 4 barrel on it with headers. Any input would be great.

If you mean letting go as in breaking stuff....you don't need to worry, although things do happen. If letting go includes the traction lock (one wheel peel) going bad, well that happens with stock power.

 

[bob331T76]

Yeah i know the stock traction lock sucks..so thats a given, but an axle breaking when im power shifting into 3rd IMO cant be good
I only ask cause im putting 345hp/355tq to the wheels and want to
run a 100-150shot but sorta scared about the rear coming apart on me

 

[bubba-dough]

I wouldn't worry to much about it. I don't. However if it bothers you upgrade the axles and carrier.

run it till it brakes. My cousin had 350 to the rear wheels and he never did brake his. And he tried to a lot.
