Throttle body size
 

I'm looking at putting a P1SC kit on my '98 Ram V10 (8.0L). I'm just going with the 8psi kit to help with towing. Exhaust is a no-brainer but on the intake side it turns out the V10 uses the same TB as a 5.2.

What confuses me is the TBs are flowed using vaccuum, not boost. If the procharger puts out 1200 cfm max, which of these TB's would you guys suggest? A little smaller to retain velocity or bigger to allow max air through there? These are my options:

980cfm
1050cfm
1100cfm

I've never messed with forced induction before, so your help is appreciated. Thanks!

I would probably split the difference and go with the 1050CFM.
With the increase in boost increasing the fuel injector flow will be something to address as well, it all has to work together.
Goodluck, Charles
