As per my sig, I'm putting down 375rwhp on a Mustang Dyno, wondering if the Mass Air and TB are restrictive enough at this power level to be worth it. I hear the manifold swaps can net as little as 5hp, as most setups are not flowing enough to make the manifld a bottleneck. Anyone have any thought?

two thoughts,

your oem intake is "LS6" and the most gain is seen using forced induction. i've not read of anything much better flowing.

the magic number on the rear end is 400 after that they tend to grenade easier.

i though the rear was a dana? i am not sure but i though it had a 8.5 ring gear that should handle around 500 hp if you dont tub the car with slicks, i am not sure of this, so please correct me if i am wrong as i plan on making around 525bhp. [ i think they blow the half shafts after 400 hp?] :cheers
