For the mods I have listed, and the fact that I plan on being N/A for a while, which size TB should I get. It's between an Accufab 70 or 75mm. Thanks for the help.

 

Seeing that you have the C&L plenumn get the 75mm TB!!!

 

Ok some people have the mentality that if you r going the N/A route you should go with the 70mm TB. Now the flow charts indicate that the best flows and gains have come from the 75 mm accufab combo followed by the C&L plenum with the accufab 75 mm TB. All the statistics where taken form a N/A engine. Keep in mind the difference is a couple of hp's so what ever you want to do. Just gave you the facts you make the descision.

 

Just out of curiousity, some poeple say that a 75mm on an N/A kinda coke it with air, but others say that a 75mm is the way to go, thanks for the imput.

 

well your gonna get different answers from every single person. i am currently using a single 70mm TB on my s281 and a 75mm on the sa15

 

Accufab TB to Accufab plenum, 70mm. Accufab TB to C&L, 75mm.

 

Accufab TB to Accufab plenum, 75mm

 

It depends on the plenum. C&L I'd go 75.

 

i just installed my 75mm and c&l today. couldnt be happier, throttle response is much better and makes a cool air sucking and slight whistling sound. almost like a turbo spooling up

 

in the sig.... dyno proven 75mm= 1-2 more hp
