AND... a small kink in the aluminium recirc fitting is an amusing resonator for bypass noise. I gotta say, it makes a gentle but effective bypass chuff + flutter at modest throttle i.e. driving in traffic. In these bypass conditions, it's sounds....just like a vent-to-atmosphere blow-off, with the all important key difference of a socially acceptable decibel level. The noise disappears with high boost bypasses, but is effective in "gentle squirt" driving. Leadfoots won't hear it. Nor will you hear it every time you take off; there's a sweet spot and rather excellently it's somewhere you can make it heard without being a mind numbingly repetitive noise every time you change gears.
All that for a beta testing model made some months ago. I'd like to suggest more than just a larger pipe although I expect that will make a difference to the response, top end etc, I've something more exotic in mind that is a more complex manufacturing construction, but I expect would "solve" the response and give more flow beyond what just a bigger pipe would, if practical to manifacture and viable to make fit in the available space. I'll post my uber inlet idea later.
I have various ideas like that and right now I amused at the thought of making a blowoff/bypass resonator from a coke bottle, too.
Some might laugh hard at this, but actually think the inlet I currently have installed could benefit from a well designed hiclone installation. I'm tempted to contact them and see if they'd put it up for dyno test. Give me one for post MAF, that gets the air spinning all the way down to the turbo - in sympathy with the turbo's spin. Part of uber inlet design, which I'll post later. Or maybe keep secret and give only to Troy.
