Re: Dave's Evo X Build/The Life of Dave blog
Me and Josh are both making good power on the 6466's. My car still had a stock intake manifold, throttle body, and no porting on the head, it made 709whp at 38psi on RS's Mustang Dyno. Josh Made over 700 on Buschur's Mustang Dyno.
The reason the 6466's cost so much more is they only come in Ball Bearing, you can get the 62 and 67 in Journal Bearings hence the lower price on the site, when you get up to the Ball Bearing option for those turbo's they close in on price with the 64.
My 64 actually spooled the same as my 62 did, at 35psi it didnt really make much more power. but the 6266 quit making power on my set up at that level (615whp on Ron's Dyno) the 6466 started picking up good power around there so it must have been right in its efficiency range, I ended up being able to make 665whp with 39psi, then it slowed down on making power until I went from kelford 272's to GSC s3's where it made 709whp at 38psi
