the revhard and drag kits come with the 12:1 disc which seems a bit high but actually works well ....if any more boost is ran, i would advise going with like a 8:1 and some larger injectors

10:1 if you want to be safe and 8:1 if you're brave......... I actually need a 9:1, at around 7psi an 8:1 gives me @ 90psi fuel pressure and the 10:1 goes up to 120. I am trying to max the fuel pressure at 100psi or slightly less. This is on my prelude though, but with all stock fuel systems, keep fuel pressures below 100psi, even if it means lowering boost..........

Re: fmu question... (loturbohybrideg)
on my LS I ran 10:1 with stock injectors. when I upgraded to 310's I put an 8:1 disk in it. It's a little rich this way but it's okay. I dont want to blow anything up.

Re: fmu question... (loturbohybrideg)
Just incase anyone is interested Vortech does not include all their "plates" in the recalibration kit. They do make odd numbers and not just the standard 4,6,8,10, and 12:1. I use a 3:1 with my 550cc injectors and use the maps on my Power FC to add additional pulsewidth. I will soon whith to the Hondata 5volt map sensor and just run everythig off the power fc. Anyway they also make a 7:1 and maybe a 9:1. Just incase anyone is between ranges.
