How fast has a..

...stock plenum and stock throttle body gone? Or maybe a 62 mm throttle body, still using the stock plenum? I am building a TSM motor and was wondering if it is worth it to step up to the PTE plenum and 70mm throttle body?

Thanks for the input..

Talk to RA. He is an anti-plenum, anti-TB guy, and you know what his stuff runs.

Ryan Guy in OR went 9.99@136mph with massively ported 8445 casting heads and either 57 or 62mm TB. T-76 and 30psi+.

However most run a 70mm TB I imagine if 3" intercooler piping is being run.

Have gone 10.0 at 134 with original throttle body bored to 62mm and modified stock dog house. I'm sure others have run 9's.
