Title: Removing butterflys in plenum
Post by: SCOOMER on October 19, 2009, 01:13:21 PM
Thinking of removing the butterflys in the plenum and porting it to the size of the gasket but dont want to do this if the cons out weigh the pros.

Im assuming the idles on start up from cold will be affected is there any other disadvantages? Also apart from the obvious more air flow what other advantages is there?

This is for a FD Plenum btw.

Cheers Scott
