Alright..



IM shooting for 400rwhp. already have turbo, and everything else required Would 2X720 and 2X1000 be a good setup w/o using a fpr and a new fuel rail? most i'll ever go is 18psi.



I already have brand new in the box ford 1600cc's and 550cc also have brand new in the box aeromotive fpr which im not sure at this point if im going to use it.

I dont want over kill mainly because i want a good transition between primary and secondarys. I'll be using a power fc for my 1990 turbo rx7.



Thanks

im using 1600cc secondaires and 550 primaries. do you have a standalone ie. haltech? microtech? to control the duty cycles and such?

I have a power fc for fc3s being shipped to me right now...

well if you have something to control the duty cycles, theres no reason transitions shouldnt be smooth, you just need someone who knows how to tune. i ran my 1600 and 550's with a stock turbo and the haltech running the 1600's at like 30% duty cycle...it was fine.

I run 550/1600 with a power fc in my FD. like stated above, it's all about using the ECU to control the injectors

thanks for the info, i'll go ahead with this setup and see how it is.
