Hey guys!
So I just finished my M50B25TU build, and got it running right (finally). I was with a friend a little while ago and he gave me an Eaton M90 from a old Thunderbird.
I've been doing some research about how hard it would be to put it on, and it looks do able!
I have a few questions that maybe you lot could answer.
1. Charge System Setup
What order should everything go in?
Supercharger > Intercooler > Wastegate/BOV > MAF > Throttle Body
Don't get all "this guy's a ricer" on me, but I'd like some noise from my pressure release. Is a BOV doable, since the M50 has a MAF?
2. Pressure Control
Would it be possible to run a wastegate, just before the throttle body and before the MAF that would allow control of the boost level?
That way I could put a tiny pulley on the supercharger, so that it would reduce drag, but I would be still able to waste some of the pressure to keep it down on higher boost.
Would I have to run a BOV/Bypass Valve as well? Where?
3. Intercooler Sizing
Right now, I don't struggle with heat at all. I have a 318i rad, with a 16" blade style SPAL fan. It moves a ton of air. :) However, what size intercooler should I get?
I would like to keep it on the smallish side, since I don't plan on running crazy boost.
I have the option of buying a Dodge SRT-4 intercooler for cheapie cheap. It's got 2.75" inlet/outlets and it's overall dimensions are 23.5" x 5.75" x 2.75". Would this be good for my project? It would fit perfect behind the kidney grills.
