Default I don't know what to do.

Probably a fuel forum topic but this is a boosted car. What fuel injectors do I need? I just pulled a 124% DC with 72# low Z injectors rated at @ 3 bar. What size are some of you higher boosted guys running? Im thinking maybe 96#, but Im kinda at a loss. I guess I could up the fuel pressure, and retune, but how much fuel pressure is too much? Right now fuel pressure is 43# and rises to 65# @ full boost, and I don't know if I want to go any higher then that. How Accurate is the HP Tuners calculations of Injector DC? help.....

96lb fuel injectors http://www.exoticperformanceplus.com...html?item=1079 and an AEM Driver http://www.exoticperformanceplus.com...html?item=1103 is what we generally use for the higher horsepower builds. If you went with a BigStuff3 computer http://www.exoticperformanceplus.com...html?item=1237 then you wouldn't need the driver, and the BS3 does a lot more than the oem computer can. Bob

You can try 65 base pressure and that will get you a flow rating of roughly 87.5 lbs/hr. They will run just fine at 65psi too.

I had PM'd you a while back on pricing and availability, but you didn't respond. How do the Delphi compare to the Siemens, as I have had pretty good luck with them, until now? I am running the Versafueler so I am covered for driving them.

I thought of that, until the boost referenced regulator shoots the fuel pressure to 85+psi.

So do you guys think 96#will work out?

I am sorry about that, I try to get back to everyone who pm's me. The Delphi 96lb injectors work quite well with a good tune. Bob
