Thread: Has anyone Used RC injectors? Few Questions...

OK so RC has High Impedance top feed 750cc injectors. I plan on getting a set. But Im wondering if anyone has used RC's and if they can be run at four bar. My plan is to not have to upgrade my fuel anymore. Ive got MSD 50lbers now. But I was maxing those with my same setup even before all the other upgrades and they cant run at 4 bar so Im going to wind up selling them.

just get some 1000cc biznatches and run them at 3 bar

Any reason to stick with RC? You can grab Siemens injectors for pretty cheap and they offer 80 lb/hr High impedance injectors for around $50 an injector. These in my opinion are a good injector with behaved idle characteristics.

Have you used those before? Damn they are cheap! I was just using RC's because they are High impedance.

Damn I might have to change my JWT order for 80lbers! It says they are modified injectors though. Wha does that mean?

It means that they are aftermarket modified. Usually this means they have drilled out the holes. I've only used Siemens when I go top feed for street cars.

Try Racetronix thats where I usually snag mine.

You can run the rc's at that fuel pressure.

So you yourself have ran these injectors at 4 bar?

I think im going with the 750cc RC's.

Im going to be running 550cc Rc injectors at 4 bar I emailed rc and they said it would be okay.
