BUT, that is probably because most draw thru systems are based on carbs and older design turbos.
If you setup a more modern turbo with a just a throttle body in front of it and injectors in the manifold - I'd bet the difference would come down to turbo sizing and tuning. But, then the issue is coming up with a carbon seal for the turbo to be used in vacuum situations ... or move the throttle body downstream and end up with a draw-thru "style" blow thru ...
I "think" I like both styles - but haven't ridden either yet!
Quote from: Bones on Yesterday at 03:46:21 PMThey don't have to be just the blue spots either, the later silver or gold spots fit as well. A lot of different model Yamahas used them so just a matter of picking what colour you want and source a pair. They have to be axiel mounted though not the more modern radial mounted.
