ok you all i have a plain old 3rd gen. camaro can some one tell me how much power it will hold up to before it will blow apart and when it does what should i replace it with dont have a lot of money.

Thanks for in put!!

HUH???

 

its an 88 with the factory gears and the rear end its a 305 with no mods and a quadra jet wiith a turbo 350 it was just a motor and trans i had laying around.

setup properly the stock 7.5's can handle a decent amount of power. i know people putting over 600hp to them...but they have to be setup with a solid pinion spacer and support cover, good gears, eaton posi unit and 28 spline axles. putting in a 12 bolt or 9" is a great way to put something under the car that will hold serious power but a bolt in unit with brakes and all is gonna be around $3000+

 

Well, I tore up a rear end (posi disc one) with almost stock 305 TBI. So I don't have much faith in those rears.
Get yourself a nice rear end bro.
I personally would go with the eaton posi if I were you.

 

An '88 might possibly still have a Borg axle. They are a bit more robust than the 7½" Saginaw axles.

 

what did you do to break it though? if wheel hop was involved, there was a larger issue than an inferior designed rear axle.

 

I went through 2 rears with my stock 305 TBI. First time was just normal wear, drive here and there, mashing the gas, and of course donuts. 2nd time I think was an installer snafu.

 

NO WAY that will hold up to dragstrip launches on sticky tires, especially with a stick, but even with a hard shifting automatic.

As long as you're staying with a 7.5/7.625 ring gear and stock housing consider it a disposable wear item if you're going to drag race the car, the same way as you treat brake pads on a car that is going to be road raced.

There is no problem with the design, it's just too small for hard use in a heavy car...

 

well...they won't last forever at that power level, but 87 T/A has been 1.38 with consistant 1.4x 60's on a regular basis...i've only been 1.64...when i get into the 1.5x range, i'll have to get on the ball with my 8.5" rearend that i'm fabbing up.

 

i blew mine up with slicks and a manual valve body 350t and only 252 RWHP

 

Heh, I’ve officially blown up another set of f-body 10 bolt gears since I last responded to this thread…. That makes 7, 3 posies and an axle or 2, add in a bunch of carnage to the BW one in my formula and the fact that I broke the 8.5” 10bolt in my truck around Christmas (long story, but I’ve got it rigged so I can put it in 2W Lo with a switch on the dash, which gives me basically 4wLo but only putting power to the rear axle).

I’m getting good at this:
