A2A Supercharged Intake Options

Rough look at some comparison logs and where I'm at currently with setup yields very promising results.

Topz says that I should be getting 15-16 psi with my setup (he's seen more results from his kit than I have, so I trust him on this). Setup is Si impeller, 9 psi pulley serp-side, and 3.15-3.00 high traction pulleys SC-side.

Filter off datalogging netted me about 12 psi @ 6200 RPM
OLD filter on datalogging netted me 5 psi @ 6200 RPM
NEW intake setup datalogging netted me 10.5 psi @ 5600 RPM

I can't find evidence of tubing collapse in the recent logs, but I thought I saw it, so I immediately eased off the throttle.

Have you thought of using a spring inside the silicone tube? It works great with radiator hoses to keep them from collapsing.

I did think about that, but I was scared that the spring may come loose if jostled, so I shied away from it. That was me thinking of a traditional spring though. The PVC looks to be doing its job of keeping the tube from collapsing, so I may be finished! I've cut another piece of PVC to put between the SC and the pass-through rectangular portion if I feel like I need to.
