Injector Question
I have a set of 450 DSM injectors on a b16 turbo motor. I have a t3/t04e turbo, 9:1 compression, head and cams are stock. My question is what is the most boost i can get out of those injectors, will 14psi be ok??
thanks

Re: Injector Question (sleepercivic)
I think injector size has more to do with overall hp output than the amount of boost you will be running. Anyway I use the calculator at the bottom of this page to get a rough idea of what a certain size injector can support http://www.rceng.com/technical.htm

Re: Injector Question (sleepercivic)
Most injectors will max out at 80% duty cycle and this is the accepted industry standard.
B.S.F.C is brake specific fuel consumption - How much fuel you are using per horsepower per hour

and what would be my fuel pressure at the fuel rail with a high pressure walbro 255 lph intank pump?

Re: Injector Question (integra-modder)
The duty cycle comment refers to how long the injectors are open. 80% indiacates that they are open 80% of the time and closed 20%. The injectors can be made to open longer but as the duty cycle goes up so does the risk of failure. 80% is what the industry considers a safe standard and reccomends not exceeding that standard.
BSFC is a measure of how much fuel is used to make power. I don't really know much about what the value means but the tech page says that boosted cars should be in the .6-.65 range. I put it to .65 for a margin of saftey with the calculations.
To know what your rail fuel pressure is you have to have a fuel pressure gauge. The idea in knowing this number is that with a higher fuel pressure you can flow more fuel at the same duty cylce using the same injector, but there is a limit to how affective this is, i would assume.

Re: Injector Question (racerxadam)
ok so back to my original question will 450cc injectors be enough to run 14psi on a built b16 block, with a t3/t04e turbo, hondata stage 3 boost upgrade?

Re: Injector Question (sleepercivic)
the injectors will only support a certain hp. Noone can really say with confidence how much boost will be needed to make a certain hp.
