BLOODRAGE Posted March 3, 2012 Report Share Posted March 3, 2012 just wondering,with porting its all about air flow,with boysen rad valve it looks as if there is restriction compaired to a stock reed cage,whats up with that? Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted March 3, 2012 Report Share Posted March 3, 2012 I don't have the boysen, just the vf but I think its basically a venturi effect and acts as an accelerator. Just guessing tho Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted March 3, 2012 Report Share Posted March 3, 2012 i had good luck with the cage but i also took a dremel tool and opened it up a little bit. it was for a blaster.. before and after Quote Link to comment Share on other sites More sharing options...

camatv Posted March 3, 2012 Report Share Posted March 3, 2012 there are 2 diff styles of rad valve the old ones are very rare. they dont have as much of a velocity effect to them.. one of my favorite intake set ups was a set of 28mm pwks and some highly worked rad valves there are all kinds of mis matches int he castings and i feel there is a lot of good in them that said a set of vf3's work just as good if not better with much less work.
