RC 550cc injectors = max hp????

I got a great deal on some used rc550cc injectors and I'm hoping this is enough for 500whp. I also will be running AAM stage 1 return line and 255 walbro pump. I believe it's plenty but I just dont want to loose sleep over this.

Can someone shine in as to what the max hp for these injectors?

500whp may be pushing it. If they are bigger than what you have, just go ahead and put 'em in. It will all depend on duty cycle in the high RPMs. RC is prone to lock up (stick open or closed) if the duty cycle is too large for them... so I really wouldn't push it... maybe on a different brand, but not RC. I'm on 750cc and 350whp... room for improvement and never have to worry about overworking them! I have a return system too.

depends how rich you run your tune. i maxed my 600cc DW's with under 450 DJ hp and a richish tune. went with stage 2 RFS and now at 85%

Blowers create alot more crank HP than turbos. You just lose alot more in parasitic loss.
