I'm having Jeff Evans e-tune my car. I have the old kraftwerks supercharger 10psi.

Now I assumed that the RC 650cc injectors would be fine for my setup but Jeff said that they are at 100% duty cycle at 7k rpms..

I'm surprised but now in the market for new injectors.

I do like the RC injectors, they idle great and work fine.

Would 750cc or 1000cc RC injectors be an okay next step? Or what would you guys suggest?

Keep in mind the blower is already maxed out and the car will only be seeing 370-390whp (according to Jeff Evans).

1000cc would work well.

Wow...mine was high too but not maxed. It was either 92% or 98% but I don't know for sure. I wasn't on the 650's for too long before I switched out to the ID1000's. I know I'm out of fuel now at 7000rpm with the new setup. I'm planning to get a return setup very soon to correct that problem but I don't know why you should need that now...interesting...

How's she running otherwise? ...good I assume?

Other than this minor issue I love the kit. Thanks for making everything simple for me. Would've taken me a lot longer if I didn't know what bolts went where. I am still surprised that these injectors just aren't doing it for me and were working fine for you.

I guess I'll be going with the RC 1000s. I am hoping I won't be needing a return fuel setup at only 380ish whp.
