The most popular one is the V1, but a little big for a BMW if you ask me. The one I recommend is the V9 G-Trim because it's designed for motors 4.0L & under. Boost comes on early and it's physically smaller than the others (tight spaces).

that's a tough question. you might have to contact Osh @ RMS (RaceMarqueSystems) for that exact info @10psi, but he may not tell you freely unless you were serious about purchasing their product. Why 10psi? Hope you're either running lower compression or a really good aftercooler for that boost. I personally wouldn't run more than 8.5psi on stock internals.

I know for a fact that 8.5psi requires a 5.5" crank pulley & 3.33" blower pulley.

Listen to superm3, the blower should be the last mod you make to your car. First you have to make sure the drivetrain, suspension, chasis and brakes are up to spec first. All that power is going to break things, have lots of money ready to fix it. Oh, I'm using the V2 at 9.8 psi (stock motor 245000km). Waiting for the motor to blow for a full rebuilt and 15 psi but it won't go. Will be running it at the track a lot next year so we'll see how it holds up.
