Well im looking into depth on the parts im going to need in my turbo build. I have officially decided to stick with the stock cubes. I will be doing heads and cam, plus forged rods and crank. Compression im estimating will be around 9.5:1. So heres my question, what fuel system should i use for this set-up. It will be running a max of 8 pounds with maybe in the future goign up to about 12 but never going over that.
What size injectors?
Single or Dual Fuel Pumps?
any other things i may need.

All us boost guys ALWAYS say we'll never go over "x" pounds of boost, but we ALWAYS do. My suggestion is go big now and don't worry about it anymore. Definitly twin pumps, unless your thinking a huge Aeromotive single or something of the sort. 60# injectors if your staying with a high Z injector, or even the newer 70+'s that Racetronix carries. Fuel lines is a toss up. If i knew then what i know now, i would have paralleled the rails and went larger lines right off the bat instead of constantly making changes as i went. Boost referenced regulator also.

Agreed with above.

My motor is a 9.78 to1 and im gonna be running 12psi on 94 octane with Meth and an intercooler.

My setup is gonna be

twin 255 intanks each fed with -6an line to a dual-6an to single -8an. The -8an thru a inline filter to the Fuel pressure regulater. Then I have motived rails that accept -8AN fittings.

Oh and im gonna be running 60# siemens (the flow about 64#)

And run the 2nd pump on a boost switch(hobbs switch) set it to when lets say 4psi comes the 2nd pump turns on so you dont have to run 2 pumps at all times.

Well at this point im looking at around 9.5:1 compression. with 6-10# of boost, 6# being my starting point and possibly making it up to 10 but not too sure. At this point( i dont kno much about compression and what not, is that a safe area to still be running 93 octane? any write ups on compression to octane ratings or what not?
