Supercharged!

[Jon K]

Hey guys, spent this weekend rushing around getting my forced induction setup done. Here it is. I am not boosting it yet as I need a better idler pulley. I also haven't picked which belt I am going to use yet... since I am swapping out a different diameter idler pulley. But here she is installed and in all her glory!

neat photoshop work. what are the specs on the blower, vortex? CFM? good to see you are ducting for a cold air intake and not going for a POD style air filter that sucks up all the lovely hot air from under the bonnet.

your intake is on the wrong side of your engine =]

...how many miles on your M50? Or is it a M50TU?
What engine quality checks did you do before deciding to install? (leakdown or something?) Where'd you get, etc, would like details on the project as would like to consider same for mine.... Happy motoring, and w/out extra weight of the 4 liter :-)

Its an M50 non-tu. 177k miles. Burns some oil. Holds 19" of vacuum so I don't really think a compression check was totally necessary. Buddy on here had 200k+ miles when he was boosting 12 psi on a M50 non vanos. VERY solid motor. I will be making 6.5 psi. Roughly 290 - 300 whp, or about 315 - 325 crank. I have a front mount intercooler i will install later. Its full custom so as for places to buy from I cannot really say. It's an ASA based charger I purchased used. Relatively expensive and time-consuming setup but it's worth it in the end. Once I have it all buttoned up I will post my insights

@JR:

Haha she is married. The stitching was rather incredible I do agree! Tell ya what, how about a shift-boot in trade for your M5? Deal? Done!

To get 300hp at the wheels you would need 366hp at the crank figuring on 18% driveline loss. 325 crank hp will net you about 266 at the wheels.

Do you think your Mom can stitch up that opening in your hood? You really should fix that....=) I'm still impressed with the French stitching she did on the alcantera shift boot...is she still married?? =)..ha, ha..

Good luck setting up the turbo, if it is anything like your photoshop skills, it will kick ass....

slick photoshop work, mate.

Nice work but how do you figure 300whp with only 6.5psi?

How? By dyno's...


An E46 323i made 295 hp wheel (corrected) and a 325i made 302 hp wheel (corrected) while a 330ci made 335hp wheel (corrected). I am putting myself between the 323 and 325, so should be about 300 ish. "only" 6.5 psi is a lot of power when you stick it inside a naturally aspirated motor with no dropped compression...
