Default Re: Injector Rail

RCEngineering injectors for LT5s are available in a couple of different flow ratings.

I see some people here are using the SL4-205s.

I used the SL4-210s in the 500-hp, Automasters Street Skinner engine I had in Barney. At 43.5-psi they flowed 200-202 CCs per minute.

Don't forget the rail pressure is regulated to 350 kpa (50.8psi) not the standard 43.5psi rating pressure. That brings the injector flow capability closer to the calibration value.

Hi, Thanks for the reply!!!. The corrosion in the rails is next to none...when I pulled the rails a little bit of water got absorbed into my towel.Then the rest smelled (and tasted) like raw fuel. The tank was removed and cleaned the year prior. The secondary injectors look like S#$T!!!!! I filled the tank full of premium and put a fuel treatment in for any remaining condensation... I plan on running the pump via the red jumper to clear the lines before firing the beast up after I go through the engine.

Excellent results w/ Accel (150821 from Summit). Purchase new Viton (sp?) O-rings from Jerry's Gaskets.

FIC, a supporting vendor: Ask Jon for new stainless injectors kit (includes gaskets and O-rings from Jerry's too. I've no personal experience w/ these, but those that do, seem to like them fine.)

Marc Haibeck put Accel injectors in mine. That is pretty much all the endorsement I would need to use those again..

One last point. If anybody uses the ford motorsports injectors and wants the injector characterization data converted to our GM calibration, that is a service I can provide. I can recommend a suitable model if you aren't sure.
