I'm in the process of designing a build up from a chevy 400 block that i have in my garage, and ive decided that i want to go with some sort of electronic fuel injection. The general concept behind this motor is for it to make ~ 500 HP and possibly have either a turbo (maybe 2) or a supercharger. many of the aftermarket EFI setups that you see through JEGS or SUMMIT have a limit of about 400 to 500 HP. I dont want my injection to be my bottleneck if i decided that i need more power. I'm basically looking for any, and all, suggestion on how to approach this, or setups that are known to handle this kind of power.

 

Lingenfelter had some similar combos. Here was some stuff taken from his self-titled book on Modifying and Rebuilding SBCs.

Are you set on using aftermarket as opposed to factory ECMs? The limiting factor in higher-HP vehicles appears to generally stem from the injector driver limiting the injector used. 50 (?) lb-hr is the highest generally that you will find in the 12-15 ohm variety. Do a google search for -> "cherry driver" injector <- and then select the "Cached" option on google...some of the DIY-EFI topics will show up that way. It at least gives you an idea.

 

500 is very doable.
And to mention T/C, or S/C makes it rather easy, but it will take some money to get it right.
You can do it with all oem bits, and save a fortune compared to the aftermarket ecm stuff.

The info's here, and you might spend some time, searching the archives for here, and the Power Adder board to get some ideas an what you need to do.
