i'm thinking of either the 8 inj setup or better yet the emanage(may not be any better for fuel but has the timing and all the goodies as well)...i know that if i run the 8 inj setup that i could use the ford #30's as the secondary and that would be big enough for what i need...i plan on 15-16 daily and maybe up to 20 during races....i have a guy who will sell me some 440's and i am interested in them...if i go emanage i can just have the emanage take care of the bigger inj's and not worry about a second set..if i stay stock then i can tap in the 2 extra inj's...all this equals that i need a ass ton of fuel to run boost, we all know this...there are plenty of guys running 440's at 15-16 psi...what i want to know is there an equation that i can use to figure out how much fuel that i need per psi or hp rating so i can figure out what inj's to use...i would like to tap in the two ext inj's w/ the emanage but there are hardly anyone using this and how to know which size to use as the extras....its easy to figure out your fuel needs when you run 4 extra inj's w/ your stockers, just add what you have to see the total cc's of fuel your engine is getting...but in that relation would you just divide the cc output of the 2 extra and add in the stockers to figure out the total amount of fuel...i have read post after post on inj's sizes and what guys are running on them...just wondering what some of you expert tuners think about this....i'm doing a rebuild and have the money for pretty much anyset up i need...i can do emanage w/ the goodies and bigger inj's, i can do afc plus bigger inj's w/ a ignition retard controller(msd or crane)...i can do the 8 inj setup w/ some form of ign retard....for 16-20 psi what have you guys found to be the easiest to tune and to maintain...thanks for your guidance...

400whp or bust.

Ok, I only know of 1 person who's tried the e-manage, Armond. I don't think it ever made it in the car correctly. So the jury is still out on that thing. Corbin is the 8 inj. guru. he also has injector size formulas on his site. http://www.geocities.com/vttalon/ The 8 inj setup is new but has been proven on a few cars. I would say it's reliable, I've seen it in action. The afc route has been proven many many times. there are drawbacks to every setup I would reccomend you do some reasearch to find the best setup for you. just read all the posts relating to fuel and you'll find your direction. I personally (as of right now) will go with the 8 inj. setup with the crane system for timing when I'm ready to rebuild and up the boost. Now depending on what options are available when I do it I may go a diff way when that time comes. I can't wait to see what the e-manage is capable of because that way it's all one unit rather than seperate systems. We'll see what the future holds but if this is a right now thing for you IMO I would go 8 inj. setup. I'm not sure wich one is cheaper when it's all said and done though. With the 8 inj. you have to buy a laptop (if you don't have one) plus the eic, the injectors, and the labor to have the injectors mounted, plus the ignition. With the SAFC you need inj., ignition, and the SAFC.
