Can you use a BOV if you wanted?
Tial Bypass Valve- TREADSTONE PERFORMANCE
I am dumping to atmosphere pre-intercooler. No filter since it will be blowing any debris away and can not ingest anything.
Good call on putting in a safety setup for that pump. I still have the oil pan spacer and a fitting for you. |
I think he was referring to something like the synchronic diverter valve, which actually open at vacuum so that air can have a shorter route for greater response. Genius actually, but for a supercharger i don't see the use. The annoying lag and slow response of a turbo I get though...
the only time you'd want recirc is to keep your car from leaning out too much when not on boost. Pre-intercooler, post, or even on it I don't see as making that much of a difference, except for maybe putting it post to make sure your pressure drop across the intercooler isn't as much of a factor in tuning...or at least that's what was explained to me before.
At 20 psi 1" diameter means there's 15.7 pounds of pressure on the valve, and at 1.5" there's 35.33 pounds. 1" and 11 lb spring is 14.013 psi. 1.5" and 11 lb spring is 6.227 psi. So when do you want it to vent is the question?
EDIT: This is all provided i didn't jack up my math somewhere...I've been paged out for work twice in the middle of the night this week so my math may not be trustworthy until the weekend
