I'm going to put a full length densecharger with the 85mm Pro-M maf, a new throttle body, and a C&L intake plenum. My question is what size throttle body should I go with? 70 or 75?

5mm isn't going to make a huge difference either way. May as well go w/ the 75 though unless it's a lot more expensive. IMO that is.

Don't forget that only 5mm difference in diameter makes a big difference in surface area. a 70mm throtle body yields 3846mm in surface area while a 75mm throttle body is 4415mm of surface. That's a pretty big difference. Not sure which is better for your current mods though.

you are going to be disapointed with the C&L plenum.... you will gain some, but not what you would with the accufab. hopefully i can sell my pos c&l and get the accufab... accufab... accufab... accufab....

if you are N/A, stick with the 70mm and get the accufab plenum.. i guarentee you won't be dissapointed.

70 mm throttle body - your doin it right as well - a throttle body and plenum change isn't worth the money unless you invest in something like a densecharger and an aftermarket mass air meter. You'll be happy with the SOTP difference. Oh and WHT is right on with the accufab comment - they are the best there is out right now - It will outperform C&L by a good 30% more hp - only thing is that 30% is only = to about 2.5 hp hehe.

What did you here about the trickflow plenium. Is c&L really that bad?. What about the mac. They need to test it. I'ts pretty expensive though.

Thanks, I'll definately go with accufab but as far as the throttle body goes should I go 70 or 75 and why?

Also, would there be any benefit to using a throttle body spacer?
