Interesting...Educate me. What's so different about the IRS that it causes a power loss to the wheels?
Edit: Ok, besides the obvious differences lol

it's from the IRS not the open air. and the stock y is 2.25"

i honestly don't know, but i saw dynos of a 99 cobra with IRS before and after a live axle swap, and the live axle dynoed 17 more RWHP. this was on a stock engine with Vortech and dumps, so it nothing to do with the exhaust. maybe the IRS has more drag for some reason

uhhh drag has NOTHING to do with DYNO numbers.[sm=wtf.gif][sm=smiley21.gif]

This is ALSO why you dyno better numbers if you have higher pressure in your drive wheels. Less rotational drag.

What warrents your friends uncle to say that the X pipe is useless anyway? is he a mustang specialist? does he work for Ford or have some degree in Automotive Engineering? Have you even seen any mechanic credentialsorlicense (whatever they get)from him?

If drivetrain drag had nothing to do with dyno numbers then UDPs would have no effect. If there's more drag in a system, not as much power will make it to the ground, brother.

Yea, pretty much everybody but deezel. The only thing I know about IRS is it's not the best thing to have for drag racing, and that's it. There are tons of post and writups about IRS vs Live Axel on the internet, just google them.

well first of all i thought he meant aerodynamic drag. and second of all last time i checked IRS stands for independant rear suspension which really has nothing to do with rotating mass(i.e wheels, tires, and drive shaft) or parasitic drag(ie. superchargers and accessory pullies). brother.

Moving on..let's take into account that it's also a heavier system of more moving parts. Power, instead of being transferred to a simple 7.5" shaft, is now driving through two half-length 8.8 inchers and a set of CVs. Theoretically speaking, bro, it could have an effect.
In theory atleast.
