N54 hits over 400whp ...!



There's been alot of tuning going on for this engine. I'm sure some are new here and are not members of other BMW boards.

I figured I'd post a link to a good read. Think of a "tuned" 135i with 400whp and more torque down low than a Zo6..!

I thought Procede V2 was fully customizable. Wouldn't it just be a software flash for higher octane?

Good stuff. I'd love to see IAT, EGT, boost, IC temp and pressure deltas....the whole smash in datalogging.

More obtainable question: anyone know what model the stock turbos are?

Mitsubishi - IIRC - itty, bitty ones at that. Suspect if I went to the sticky on the N54 at the top of this forum, I'd find it . . . (be right back) . . . nope, not in the N54 engine notes. There's a thread in here somewhere that identifies the model numbers.

Looks like a TD03-10T. Small...probably only can make 7-8 psi in it's ideal range. Mitsubishi turbos are very reliable (water & oil cooled) and proven, and tend to be quieter than other makes.
