How much HP would 42's and a FMU support??? Has anyone done this. I know they make 50's but they are EXPENSIVE!


THANKS

I think 42's alone are good to over 500HP....so with the FMU I would say 575-600+.... but you'll need plenty of supporting parts in the fuel system to go to that level... the stock rails are maxed with 42's and you will need a serious pump as well.

with stock lines and rails I have seen 485-500rwhp Safe,
but maxed.A fuel system will help,but still maxing the injector
at that level.The fmu will help for sure to get away with more
I would go with bigger injectors?I seen 530-550 with fmu!
Good luck man.

ys-trim blue 89lx are you sure about that. Im at 420 and only on 30#'s. I would think you could get higher 500's with 42's.

Has anyone ever tried this?? By looking @ the charts 42's and a fmu Should be enough to make 650 to the tires (my goal).... It will probably run pretty rich though, oh well...
