hey guys im turboing my b18c1 and was wondering if the injectors i purchased would be enough for wut im shooting for

like i said its a b18c1 im only going for 325-350 whp and i have 550cc rc injectors

i did the calculations through RC's website and it seems like im wayyyy short

also they give u the fuel pressure set automatically at 43.5PSI so im also wondering wut kind of fuel pressure i can make with a Walbro 255lph fuel pump on a stock fuel rail in order to compensate for my lack of injector size and also if the saturated 550's can handle and higher pressure.

since were on the topic wut break specific fuel consumption will my engine require to make the horsepower im shooting for?

mayb i should put this in engine management and tuning but i figured i mine as well start here

thanks!

 

You'll be fine

 

that's about the limit or so.

 

use .6 for the calcs and quit fking saying "wut"

 

bro no 1 cares WUT u think lol

 

from the calculations i came up with on the RC website it shows that at the 43.5psi they test at im pretty much screwed

 

unless i run ar 70! psi which, correct me if im wrong, sounds pretty high

 

Listen to Mac! The 550's will do the job but thats about all there capable of. The calculations on the RC site gives you a 30% window for a safety margin. Maxing them out or just about will get your goals. If your concerned with this then stop complaining about the rc calculations and get larger injectors

IMO go larger on injectors you wil always want more power and having larger will give you room to grow. id or fic 1000's ftw

 

I would always go bigger when buying injectors because you WILL end up wanting to make more power down the road. Phearable.net says 550cc = 330whp-380whp

 

First off who was complaining?...second off I scored the injectors for cheap that's why I got them

 

Does it give u an idea of wut kind of fuel pressure you need to run?

 

for mid 300whp range on 550's your going to probably need to run a static fuel pressure of 45-50 psi so be sure to run a walbro 255hp

thats the link i used to calculate...i calculated everything with the 80% duty cycle i heard anything over that isnt good....and i typed in 60 for the brake specific and 70psi and thats how i got into my range

 

People have made that power pushing 450's. It will be fine on stock fuel pressure

 

Like i said the RC calculations give a 30% window safety margin. Like lightning said people have pushed 450's to 350whp. 550's will do just fine. set your static base pressure at 50 psi for a little added security and your good. its not like the engine is going to blow up. you will just run out of fuel if anythign and not be able to tune past a certain boost pressure. or if your really concerned sell the 550's like i said before and go larger thats your options

 

the injectors you have now will be fine.
