Ok, so I just got my hands on a JMFab "Drag Version" intake manifold for our build and it is flanged for a 75mm TB. Now, I currently have the ETS short-route UICP, which is stock diameter. I am being told that going to 3" UICP is the best option for the EFR 9180 turbo setup we are doing sinc we will be making BIG power. Any thoughts and ideas would be greatly appreciated, ESPECIALLY with data. THanks!

 

A couple vendors tested the difference between 2.5" and 3" piping on pretty high powered cars and the difference was under 10 whp if i remember correctly.

 

aside from Boomba, what are some GOOD TB options for 75mm?

 

Turn around and sell the short route UICP to me and buy 3 inch if you want

 

Nevermind. We are doing 3" custom IC pipes and the Accufab 75mm, 4.6L TB.

 

i ran boomba tb and 3" uicp on my drag manifold also.
