Message	I've done three different (style) TBs now. Z32 50mm, Stanza 60mm and 348 54mm. All TBs flowed on the (exact) same machine, Superflow 600 @ 28" H20. Z32 50mm = 350 CFM CNC'd 54mm = 468 CFM 34%/236 CFM increase overall (dual TBs) Stanza 60mm = 534 CFM CNC'd 63mm = 656 CFM 23%/244 CFM increase overall (dual TB on Z32) Ferrari 348 54mm = 458 CFM CNC'd 348 57mm = 557 CFM 22%/198 CFM increase overall (dual TBs) I'm glad that my 54mm Z32 TBs outflowed the stock Ferrari 54mm TB's. My 57mm 348 TB outflowed the stock 60mm Stanza TB as well, that makes me feel good. ;) People have asked me about the Z1 58mm TBs. I have not flowed one (I will soon) but if I had to guess I'd say somewhere between 500 and 575. This is just a guess based on the numbers above. Thank you.
