on a NA 12.5:1 motor. i plan on putting about 215 whp. what size do i need? 310, 370, or 440
thanks

 

370's of 440's should do.. might as well get 440's, you od'nt know where you'll end up.

 

440 may be too big.

You'll be approaching 100% duty cycle with RC 330's at 215whp n/a. 370's get my vote.

 

so 310's are too small?

 

that would depend on injector duty cycle.. what type of fuel managment are you planning on running.. my original plan was for 200whp n/a with 370's.. i ended up doing that with turbo and duty cycle was like 60 or 80% at 60psi.. but a/f ratio isn't as low with n/a so you might be o.k. with 310's

 

370's are the ticket. Above 225whp 440's wont hurt though.

 

i will be using a vafc and FPR to control fuel

 

???

 

also do i have to replace my clips? anyone know where i can get these?

The clips or the injectors?
Same place I'd guess.

 

yea, im looking for somewhere to buy both, i should have explained myself i guess. maybe someone here has a set, or knows a shop that has some kind of deal going

No such thing as too big when it comes to fuel.

 

sgt, will the 310's get the job done up to about 215whp?

 

stand alone = 370s - 440s

chipped w/ vafc - 310s max

270's will be enough, anything over 310 is overkill.....

 

I was using prelude injectors when I was at 218whp. They were uncomfortably close to 100% duty cycle. When I changed my pulley, I upgraded to 440.

totally agree. 310 is all that you need. over that idling issuses can occur and possibly harder to tune
310 the way to go for your power

 

if you have a standalone go with bigger injectors like 440's because then you can just downtune them and you will not have idling issues I was running 550's on my setup and they were fine now I have 440's though sold my 550's. But if your running a vafc get the 310's

 

310cc should be suffice in a all motor app.
