.......You may shoot some flames on WOT shifts.
Thanks for the infoYour MAF is positioned in front of the blower which is before the BOV. Once the air runs past the MAF it sends a signal telling the DME you have XX/mass of air going in to the engine. When the BOV vents to atmosphere your motor no longer has that much air going towards it and it will run rich. You may shoot some flames on WOT shifts.
I agree with Zak on this.
:excited:Trip, I will fly to your location to video "FLAMES" coming out the back of your Bimmer ! That would be........Awesome ! ! !
I found out today after Starting it up for the First Time Surging Idle :banghead: I am running -6psi Spring ATM. I am going to try to swap it out for a Tial QR BOV -3psi and go from there.I hate to say it, but that BOV is the wrong part for a "draw through" MAF setup. If the sequence was Compressor - BOV - MAF - Engine, then there's be no problem. But as Zak said, you'll now have an engine that thinks a lot more air is being pushed into it than really is the case, and this is going to cause some really rich running at part throttle and upper RPMs.
If you have cats, it will likely kill them fast as well.
Turbos don't suffer as much when configured like this, because mass flow is controlled my manifold pressure/vacuum. With a SC, mass flow is directly proportional to engine speed...which means at 5000 RPM @ light throttle the compressor will be running pushing a ton of air through the BOV.
Ever wonder why the S65 supercharger kits have 2-3 BOVs? It's because of the mass flow that needs to be bypassed at part throttle. They are also tuned completely differently than this kit.
Sorry to deliver the bad news like this....
No sound on my comp at work, so I can't watch the vid
On flat shifts you'll definitely spit some fire. My car used to catch the rear end on fire on high RPM lifts.
Brady, the only person running a blow-through setup on an e46 nonm is NickG. I believe he uses a Ford maf that's been calibrated appropriately.
I sounds fine, and you will still have a woosh noise. Have you driven it yet?I emailed ATP and order a TiAl QR Valve with -3psi spring and will be returning the Q. I guess, I can give up the WHOOSH noises. ;D
You can't blow through the OEM maf. It isn't designed to handle any sort of oil, plus you'd need a different tune. When you blow through the maf, it would effectively have to measure pressurized air, where as the draw through setup does not.I didn't know if Anthony could cut into the piping past the BOV and put the MAF in there. Just a thought.

Mine has a little play, but not enough to cause any strange noises.Question for David, BMWKnight and JoshZHP. When the car is running does your mechanical tensioner moves around? Mines move alittle not sure this is acceptable...
