im getting a good deal on a BBK throttlebody. Is it better to get a 75mm or 70mm? i plan on supercharging my car in a couple of months. i will really appreciate your input.

 

if you will be supercharging it, get the biggest one you can

 

With no supercharger I would go with the 70mm but if you plan on supercharging bigger is better![sm=smiley20.gif]

 

Just to pick some figures out of the blue,
What if the discharge tube from the supercharger is 70mm in diameter feeding the throttle body and the intake plenium on the other side is 70mm in diameter what would you gain by the throttle body being larger?

well if your getting the s/c then why buy any of them til you do so you can match your parts to work as one....if you mass is stock then the T/B won't help you a bit

 

What if your going with Nitrous? bigger better or it doesn't matter?

 

it's good to wait and make your plan so you don't end up with mis match parts and end up buying more parts
