Hello guys! I looking for 50lb fuel injector for my 500efi I called marren at fuel injectors.com and he said they don't make them anymore. I'm kinda lost right now and any help trying to find a set would be very appreciated! This is for a procharged motor. And I did call pro charger and they're no help.

Be careful. I had Procharged 500's years ago with AC Delco 50# injectors and 2 failed....at WOT. Marren was the one who test/and confirmed, that the injectors were junk right out the factory. He sold me 2 complete sets of replacements but I don;t remember the brand.

I really don't want to use anything fuel related with pro charger. I wish they made a substitute or something.

Try RC Injection out of Torrance, CA. They make some high flow Kehein style injectors that may work. I've used them and a few others on the boards have as well.

Holley has several sizes. I just put 48lbs in my 500efi.

You can also try injector dynamics use them in all my forced induction engines have some supercharged ls engines making over 1500 hp never have had a issue

How much horsepower are you making? Do you think you need 50lb injectors? I've got built 540s with vortec chargers running 43 lb injectors that make 800 hp. And I'm good up to 950 with them.

I'm trying to make around 700. I'm having Mark do the ecm flash for me and he said to get the 50s. And thank you all for the replies

Raizorsedge. How do you like your holly injectors?

PM Arcticfriends- I think he is set up as a dealer for a brand of injectors and can also flow test. (I'm not 100% sure he does it for business though) He really seems to know FI.
