Ok, i grasp the differences between the VF30, 34, 22... but what the hell is a 23, a 29, and a few others? and what good are they for? the 34 is a typical sleeve bearing 30, only its BB correct? probably a little quicker spool and all the bb benefits.... then the 22 is like the "drag turbo" so to speak, slower spool, say 4200 so i hear, but top end like a hammer... the 30 is as responsive as the sleeve bearing turbos get, but it lacks the spool and a little efficiency when compared to the 34...

now im all screwed up, and i dont know what to do... this isnt for a target HP per say, its more to find out what each turbo is capable of, and compare em....

thanks in advance,
mark
