Message I flow tested three TBs today.


58mm, 58mm ported to 61mm and my billet 62mm TB.
Tests were done on a SuperFlow 600 @ 28" H2O

Untouched 58mm = 484.16 CFM

Modified 61mm = 566.98 CFM

Billet 62mm = 598.83 CFM.

So here's the entire rundown.

350.62 CFM = Stock 50mm INCREASE
468.28 CFM = CNCd 54mm (33.5%)
484.16 CFM = 58mm (3.4%)
534.26 CFM = Stanza 60mm (10.3%)
566.98 CFM = 58mm to 61mm (6.1%)
598.83 CFM = Billet 62mm (5.6%)
656.08 CFM = Stanza to 63mm (9.5%)

I should have some photos of the 62s for you guys in a day or so.
