Default New 9inch!

I finally got my 9inch installed! It has 3:70 gears, 35 spline w/ spool. I also added a adjustable panard bar, adjustable torque arm, adjustable lower control arms and subframe connectors. The 9 inch has a wolfe roll bar. I was wondering, with my car making 435hp to the rear what kind of 1/4mi times can i expect? What kind of 60 ft times? I have a spec 3 clutch, what rpm should i launch at (manual 6 speed)? How long should i wait before i start lauching it? Thanks! I'll post pics later.

They say around 500 for a break in is usual. You should also run it in the air in gear for a while as well. Good luck and congrats on the new rear!

Hey, Thanks man! I'm very happy with it. It's a bumpy ride because of the suspension mods but i know the rear is set up to go! Also, the spool is very different from a posi, so you have to be real careful going around corners. This is my weekend car so it doesn't bother me too much. Thanks again!

Put 500 on it, make sure its not whining, change the fluid and make sure theres no metal in it (to make sure the lash is set well, etc..).. If so, go beat the hell outta it


But we don't know the rest of your suspension or tires, so how can know what your short times should be? Kind of an opened ended questions, but assuming you're on tires, and a good suspension, and willing to launch it. You should run some solid mid 11's and cut 1.4's I'd guess, once you get all the suspension dialed in

5-6000 on a et street or better tire, you'll have to find your cars sweet spot, start at 5,000 work your way up, if it bogs add more rpm if it spins you lower it

Thanks Krazy, I will try that. Just want to break in this rear properly and get the best times possible with my setup.

Had her out last night! Lot of compliments from other muscle heads. It feels good to have a dependable rear!
