What injectors do ya'll use???
 

I was wondering what size injectors do ya'll use? My buddy at work said that the 8.1 injectors, which are 31 pound, will not support 550hp. I was also wondering when is it time to update the stock fuel pump?

Re: What injectors do ya'll use???
 

Well im using the 42lb svo's
think there rated around 600rwhp, well the guy who owned them before me pushed them to 576rwhp

myself and 2bseen use the foed/svo/green 42# injectors.

lol...started wiring up the 83s on Sunday...should finish up when I get home on Saturday!

Prior to that 38 lb/hr.

Here is a fuel injector calculator.

Just going by your name I'm assuming these are going in a truck. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> The car injectors have different plug harnesses and might be a different physical size also(not real sure about that). Parish8 over in the truck forum got some 41# injectors from www.rceng.com that are a direct swap in the trucks. I forget who but, somebody else cut and spliced car harnesses onto their truck so they could use different injectors. Do a search over there and you'll find the threads. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

yeah, those ones that parish bought for his truck were direct replacements. BUT... if you try hard enough im sure you could modify your fuel rail to sit a little higher and then just buy the harness adapter from shaun (valvegod) to use ls1 style injectors on the truck.

btw, i have seen it done before, so i know it can be done <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

What #injectors come stock on a 2000 formula LS1? I've got a 5psi procharger > should I change my injectors? If yes, what # injectors should I go with, and will my computer know what to do? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Cool!!! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Yes these injectors are going into a truck. LS1, small cam (205/212lsa116.5), ported heads, forged pistons 9:1, and a Vortech. I hope the fuel pump holds up.

PS - truck, it sounds like you got a cool project in the works. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
