Well, this summer I should be getting a supercharger.

A mechanic recommended getting an 8.8 rear axle (http://www.newtakeoff.com/mustang_v6...373_ratio.aspx or http://www.newtakeoff.com/mustang_8.....55_ratio.aspx) to handle the extra power from the engine, and to improve torque

But I was wondering if a new differential (http://www.americanmuscle.com/ford-28spline-75-lsd.html) and a new set of gears (http://www.stage3motorsports.com/pro...s-75-Ford.html) would do the job?

So - basically - is the new rear axle really necessary?

If you are going with the supercharger then I would say yes, straight and simple.

Alright then - and which axle? I want to do some racing (once a week)

just an 8.8 GT takeoff
newtakeoff.com has them with different types of gears

Get an 8.8

all you need is the flange to make it connect to your v6 driveshaft

8.8 with a 2003 Cobra pinion flange, and use your existing V6 driveshaft w/o issue.
Choice of gears is up to you, but with a supercharger, 373's or even 355's are acceptable. 410's are a little much with a blower.

Where exactly can I find pull off parts?

Go with the 8.8 - bigger, stronger, and will hold up to track use. I tried building up my 7.5 - bent the pinion launching on drag radials before I had the nitrous or the supercharger on it. For what it cost to try building up the 7.5, I would have actually spent less money just going with the 8.8 take off to begin with.

at a junkyard maybe. but that speedconcept pricing is really good about 100 bucks cheaper than NTO
