ATI owners
ATI owners I noticed that getting over 13psi from a D-1SC is hard. Most people have to get the MMS pulley and 8 rib setup to get there. So why not just go with a F1 unit since its only $400 more and then u dont need the larger crank pulley to run 13-15psi with no problems due the better ratio right? If u think about it, its going to be the same cost for both setups after they are done right?

Re: ATI owners If I had to do it over again, and knew I would be looking for more boost, I would of gone to the F1, but I'm going to see what I can do with my bigger crank pulley 8 rib D-1SC setup...

Re: ATI owners Anybody that tells you that they do is fooling you. It varies with too many things. If I were to make a recomendation with the mods you state (headers, exhaust), I'd "recommend" you go with as low as 3.20" to 3.40". 3.40" may only get you 8 PSI max, though, with headers/exhaust.
And then, there's slip...
