what cfm at 7psi with a 12a?
Ok I got a 12a turbocharger for my d15b7 stock internals..I need to know how much cfm can my car take with an fmu? cause with a t3 at 4psi is like my 12a somewhere around 7 or 8psi right? so its not really up to psi its in the cfm's right? so how much cfm does a t3 put out at 8psi? and how much psi do I have to go up to make the same amount of cfm with my 12a as the t3 @8psi..because just say if you get the t3 with fmu and @8psi it would put out just making up a number say 350cfms well just say teh 12a @ 8psi would only put out 240cfm..do you get what I am saying? if so would I be able to turn my 12a up to the a psi that puts out 350cfms?even if it was like 12 or 13 psi? any info would be great...thanks

actually I got it done just like 30 min ago and I looked at the turbo for some reason and seen rocks from my gravel driveway in the fu*kin turbo lol..so I have to unbolt in the morning and dump'em out..But I will let you know how it turns out at stock 7psi.but even as small as the turbo is I think it will be pretty nice increase in power that we can feel..well I am hoping it will...so nobody knows or just dont understand what I am saying?

well got the stuff on and cleaned out..lol..but my plugs are bad so I am waiting for my mother she went to get them for me..I am all sweaty and stinky lol..but its spools up pretty good, it smokes slightly, I used some flex pipe hose from lowes its 3'' flex tubing which only cost 7 bucks so I am gonna try that until I get real IC piping..I will post up some pics of my finished project..its a 89 crx dx with mpfi swap and obd1 re-wire with z6 head and p28 ecu with vtec wired into the ecu and a 5spd si tranny..I just hope this turbo will make me happy and give it a lil more umpth..lol..

Re: what cfm at 7psi with a 12a?
yeah i got the same turbo, actually building one, its pretty small what plp say, i got a zc so hopefully it runs good, did you orderd your own adapter plate? or you made it your self, i do have a HF manni layin around so i just need the adpater plate and the peace that goes around the exhuast side of the 12a, im kinda new in the tubo scene but the charge pipe your talking about is actually the tubing right going out of the intake side of the turbo right? lol, if you can post some pics up it be awesome, later
