70mm is great unless you plan on using a S/C someday then a 75mm but only then...

I would also base my decision on whether or not I was ever planning on replacing my Upper Intake Plenum. If you have that mod planned as well & you're going w/ say Accufab get a 70mm TB. But if you're gonna go w/ a C&L Upper Intake Plenum get a 75mm TB.

A throttle body alone isn't going to make much difference, but matched with an upper intake plenum, like Dragon or C&L you would probably want a 75mm.. for Accufab plenum, a 70mm t/b. Those will make a difference.. REad the article on plenums on www.modulardepot.com. the test throttle body was in favor of the Accufab plenum. With a 75mm T/b it would probably be fair to say that the Dragon and C&L would have put down higher numbers
