my W5’s were the first set Ryan( Shady Dell) ever did.
Brett actually, from what I understand, did part of them and Ryan copied the rest.
kinda interesting, those heads ultimately ended up on a very reputable bench( Best Machine) later on, and another set, done the same way, ended up on another reputable bench. Very well known guy
on both those benches, both sets struggled to get over 300.
that said, mine ultimately ended up going right at 140 mph in East coast mineshaft air, at 3220.
that is a VERY honest 700 horse.
Moral to the story, flow numbers definitely aren’t everything….at all
