Some have said for the 1500$ Its not worth It on the m52tu

Ive never dynoed the car wich I intend to do some time soon but Im curious as to what my car Is putting out as we speak with these simple mods I have as we stand Intake,Full catback (no cats),Pulleys,Intake manifold swap and a shark tune,

Just so you & everyone else understands, building a high HP / high revving (7000 RPM or more) N/A 2.5L, 2.8L, or 3.0L is a VERY expensive undertaking.

shifty1982 & his 2.5L are what I'd call a special case, why?
Because has something that 99% of us don't have, (besides money) he has a very competent BMW ECU tuner. In this equation, his custom tune is worth its weight in gold. Without it, you have almost nothing, well, a lot less in the bank anyway.

If I owned a 2.5L E46 & wanted more WHP, I'd do it this way:

1) Supercharger, my first choice would be the VF Engineering supercharger for these reasons. A) Most cost effective B) Self contained oiling system C) The supercharger "traction oil" is about $10 per oil change, not $125 or $300 like other brands D) User replaceable supercharger pulley ($78), the supercharger does not need to be sent off to the manufacturer.

2) Header.
