My guess is the hart style will out perform the st escos inlet at higher power levels say 500+.
Do bear in mind that i,m just an enthusiastic home bodger and get all my info from the interwebs so could be complete tosh.


I am running the AS hart style with good results - i have mild porting, ab07 inlet cam and the plenum. MSD said it was breathing rather well.
I guess the plenum would contribute towards that. With a old school setup on a L8 & TT T35 i,m making 360bhp at 21psi on msd's rollers. So not to shabby.
