Are these enough?

Im installing a vortec ho kit with intercooler in the next few days and have some fueling concerns. I already have the recetronix kit with wire harness. The kit came with bosch 38# injectors. I believe they convert to about 43#'ers with ls1 fuel pressures. Im hoping for 475-500 rwhp with around 8lbs boost. I have been told these might be enough or might not be enough. Any thoughts? I dont wanna replace them if they are up to the task as Im not looking for more hp in the near future.

If u make around 475hp it more than likely wont be enough. I had the Ford Svo 42# injectors and was maxing them out with my stock 3.125 pulley which made 6-7psi. Mods to car can be seen here along with dyno graph= https://ls1tech.com/forums/dynamomet...nod-today.html

Did you ever run the blower with stock cam? What #'s did it make? Boost and rwhp. I just ordered siemens 60#er's today.

I never ran it with the stock cam. I was going to keep the car all stock and run just the supercharger, but the mod bug bit real hard and I just decided to do the cam/headers/exhaust etc at the same time i put the supercharger on.

if you are asking me, mine was just on the stock fuel system with a inline racetronix which I am in the process of upgrading to dual in tank walbro 255's.
