how much boost can 1200cc secondary injectors support? does anyone know for sure? im trying to decide between non seq. and apexi rx-6 single turbo and i want to know if my 1200s will support the 17psi from either one or both. thanks for any help!

 

I doubt it, although they would probably work along with 850cc primaries. If you don't have emissions and are seriously trying to put that boost level down, I would just go with 1600s in an aftermarket rail.

 

I use a stock seconary rail with 1300's on my Rx-6. I get around 92% injector duty at around 17psi...It works, but I plan on upgrading in the very near future.

 

850cc and 1200cc combo will support just over 400rwhp at 85% DC

 

I am running 1200's/750's. I am making 360 rwhp at 12psi, with 90% duty cycle. This was tunned by Steve Kan. Hope that helps.

 

thanks a lot guys! your help is very appreciated. one more probably dumb but quick question. will my stock 850s drop into the primary rail with no modification?

 

slight modification...mill an 1/8 inch off the top (IIRC)

 

thanks buddy!

 

1600cc FTW
