How much power can a 10-bolt axle take
« on: January 18, 2007, 01:11:16 PM »
Does anyone know how much horsepower and torque a 10-bolt rearend can normally withstand, before its time to upgrade to a 12-bolt or 9 inch?

Thanks!

I have had alot of cars pulling close to 500hp if not a little more and so far the rear ends have held up just fine.  Once you go far beyond the 500hp mark, then you might want to think about upgrading.

i am going to install a crate 502, and am wondering if i should just go ahead and upgrade the axle while I am at it.

Well you could upgrade to a 455 or a stroked IAII instead of a 502.. :)  Know some people who could get a healthy pump gas engine under your hood that wont make all of us Pontiac types just walk past your car..

Anyway, the 10 bolt will hold up okay untill you are hitting it with slicks, nitrous, or 4000+ clutch dumps or a huge stall with a real engine.. :)
Performance and general repair tech. Traditional Pontiac V8 is my specialty, as well as automatic transmission repair/diagonossis. 2nd gen speciality, and with the addition of the 98 Formula 4th gen LS1 I am getting to know them real well. Holley and Qjet advice as well.

Chalk mark restoration and date codes arent my thing. W.O.T. is my thing..

Is it strange to have 9 firebirds?
