Alum Flywheel - HELP

1074 Views 9 Replies 4 Participants Last post by  gt-38
Anyone have exper with using Alum flywheels on 5.0? I just put a Alum FW, New clutch and Alum D/S. It feels like I've lost 1/2 my power.... I understand the rotating mass concept, but It seems to me the car should at least accelerate hard, then drop off between shifts, but this thing is dead across all gears and RPM ranges.

One note-- I did also replace the stock exhaust with a set of BBK equal headers and a BBK off Xpipe- The X pipe doesn't reach the flowmaster muffler pipe on one side I have to get a shop to modify.. So maybe the lack of backpressure???? One side of the X is bolted up the other isn't.. The power loss is so drastic, doesn't make sense to me


Please send help.. This is the project from hell (Theres more weired stuff for later) :sosad:

You need to get that exhaust problem fixed. That can majorly screw up everything.
3.35 is the stock first gear on T5's , not 2.95. I dont know where you got a 3.55 gear but that would be much worse than 2.95 because 2.95 is a much longer first gear. I put in a 2.95 first gear for that reason.

2.95's were stock on Cobra and T5Z transmissions.

Changing your first gear will have no affect on any other gear. If you want to change the rpm in that gear you need to either change that gear in the transmission and/or change the rear end ratio.
