I was just wondering if i connected a switch to the cold start injector as a method of fuel enrichment at high boost levels?. Can the cold start injector squirt enought fuel to work as a boost of fuel for the engine. Anyone try it.
do you think it would be accurate enough to get an exact amount into each cyclinder... i think if your going to add one it needs to be much closer to the intake pipe if not on the intake pipe?
yes it would flow enough to give just enough of an increase but as Sean has pointed oyt, the dispursement wouldnt be accurate enough. Are you having trouble with leaning out at high boost? If so im not familliar with your set up but youd be better off going the more travelled paths with adj. fuel regs, dif injectors, dif pump etc

A cheaper, more reliable alternative is to use a rising rate FPR which increases fuel pressure with boost
what injectors and what boost level and what fuel type are you using? then i need to know what fuel pressure and which regulator you are using?
Standard ST185 injectors Standard ST185 boost, up to boost cut. 98 octane fuel Car has Sard FPR, not sure of its pressure. If i could gain like 5-10hp, that would be great. i'd like to gain as much power for a standard setup for the dyno. This is just one mod i'm taking incto consideration, dont know if it will overfuel engine etc.
well check your fuel pressure first and make sure it's to spec. then i'd install a FCD. you can run like 17psi on that.
