I've got a fuel pump voltage booster on the way. I wasn't sure if I would be better suited to get an inline pump or volt booster. The pump in my tank is setup to feed the stock 38# injectors at a rail pressure of 62-64psi at WOT. I figured if the stock fuel systems on non-flex-fuel trucks require an inline pump with the Radix and I didn't, that my stock pump must be a little bigger than most. So I assumed that a voltage booster would get me where I needed to be pressure wise on the slightly bigger injectors. Crazy??

 

quicksilverado is using the same marine injectors and he is pushing around 550rwhp. Now he is using alky as well...m-10 nozzle that does add some fueling. I have used the 42# svo injectors myself in the past. They can do 600rwhp on a turbo f-body...been done many times and are VERY easy to tune

 

I haven't bought the injectors yet. Does anybody know where I can get a set of the 8.1 marines at a good price? The 42# Fords are only $269 and with our higher fuel pressure they act more like 48#'ers. I'm damn tempted to get 60#'ers and be done with it.

 

Get the 60's if the dude has them and they are less than $400. That's how much the 43's are. Just make sure you tune for them.

 

Siemens Deka 60lb Injectors $439, thats $170 more than I can get the 42# Ford injectors for. After the 50 shot of N2O I am done modding the engine so I don't know if I really need to go 60#'s. Never heard of this brand, are they good injectors?

 

Check out Racetronix for Delphi and Siemans (Deka) fuel injectors.
