I know that i probably sound like a newbie with this question...but i need to figure this out and the best way is to just ask so please dont pick on me or anything. I keep seeing you guys talking about the FMU(im guessing you mean the vortech...does anyone else make it?). When i read you guys' post about it i always see you talking about what disk you have and what the ratio is. My question is, what is the ratio and how do you know which one is right for your setup....i mean ive seen guys on here with crazy cars that had like 8:1 and ive seen other guys that had like 12:1(i think i even saw a 4:1...but im not sure). And what is the disk...im guessing that it has something to do with changing the ratio or something but i dont know how it works? Im about to put a b18 in my rex(just got to put the clutch in it) and i plan on turboing it sometime early next year. Im planning on a mild setup(t3/t4, drag mani, big front mount, RFL BOV, and custom hard piping) ...what fueal setup would you guys recomend? I was thinking DSM 390's with a FMU(thats why im asking about them) and an inline fuel pump until i have enough money for HONDATA...does this sound ok to you guys? Sorry if this is a stupid question but i just wanted to know so that i dont use the wrong fuel setup and blow my motor. Thanks.

12:1 means for every PSI of boost, it will raise the fuel pressure 12 psi above idle. (idle, i think....i just got done studying my *** off for econ, thats all I can think about)

 

Thanks man...that would make sense. LOL. Anybody have anything to say about the other stuff...like my planned setup? Thanks alot.

Seems like the larger the injector, the smaller the ratio.
So with stock injectors people use the 12:1... with upgraded injectors maybe 8:1.

 

yeah i wouldn't go with the RFL, personally. a. it's ******* ridiculously loud. like, annoying. and b. sometimes it gets stuck, so bust out the wd40
IMO the greddy type s sounds a lot better, or even better, the HKS ssq.
