Its a 65mm. I need to change the sig. lol. I gave the poor guy a hard time.

it breaks down into this ...

if u have a stock or any other plenum , 70mm is the way to go

if u have a c&l plenum , c&l and only c&l will get more power with a 75mm , even if ur n/a, like those links jdan posted, c&l has done testing showing that 75mm and their plenum gives higher #s than their plenum with a 70mm tb

so if ur going with a c&l plenum get a 75mm , anything else stick with 70 mm

That's exactly what I read.

like anything else it is going to make more top end power at the expense of the botom end

Most racing is done through the top of the power band anyway.
