E36 M3 VELOCITY STACKS WINDOWS
Windows up, my daughter filming - it's a bit definitely louder in real life, especially with the windows down. I have a stock exhaust so the car is basically stock quiet until over 3000rpms and than you Any sound clip / video would be awesome as well 😃Sure, I'll keep you posted. I really wonder how it'll do in the longer term - please continue to post as time goes on to show the progress? Perhaps this could be a beta for a kit that you could potentially provide for the community if enough people have interest. Probably my best option is to use a CSL style airbox.so that's why BMW made that eh. I've thought about running hose into the exhaust using a venturi valve, or perhaps routing it through an oil separator/oil catch can and then into the IACV.but I'm not sure I want to route it directly into the IAVC - sounds like a great way to gump up the IACV. The stock system dumps back into the airbox so you don't smell anything, but running open velocity stacks there really isn't a good place pipe that back into the intake. I've designed a plate to go under them to help direct airflow into the trumpets, but I haven't put it on since I'm not sure if I want to keep this setup or not.īut it's the PCV system, running an open PCV sucks - just sticks. The PCV can was my first beta print, I was going to reprint one in black or paint it black - I just had a bunch of white filament.įor tuning, I'm running MSS54HP non-h-bridge DME using a stock CSL tune with a CSL MAP & IAT sensors. Literally, the only thing that cost any money was the ITG filters ($22/each) Stock thumpets out of the stock airbox - same as the CSL turmpets.Īlso designed a PCV catch can to route brake booster and valve cover vent, it connects on the bottom to the stock oil return I designed a clamp in Fusion360 that holds two trumpets together (so you need three total) so all the factory trumpets can use all the stock mounting hardware. While I've been designing a CSL style airbox in my spare time I designed I'd try the Velocity stack / open ITB setup.
