97cobra s trim....what size injectors?

sn95gt19 · 03-05-2003, 01:31 PM

this is actually for a good friend of mine...

he has a 97 cobra with bbk longtubes, 4.30 gear, and an s trim
he just bought 42# injectors but is also going to use the fmu, do you think he will still need the fmu even with the 42# injectors. he is looking to get 14-16psi out of it. he is also getting the car dyno tuned w/ custom chip from alternative auto (lidio)

i would use the fuel system analyzer but i have no idea what kind of power he would be putting out with that combo. do you have any guesses on how much power he will be putting out?

thanks

I would also use the 42 lb/hr ionjectors, but without the FMU. Both the supercharged Lightning and the supercharged 03 Cobra come from the factory with 42 lb/hr injectors. If a custom chip is being "burned" then have them do it for NO FMU! The driveabilty and tip in throttle responce will be much better.
