Yeah, so mine are 103lb/hr at 4 bar.I'll most likely be at 58psi, but if I can get away with lower I'll do it.

hmm every chart i show online said around 997cc at around 43.5psi for a 95lb per hr injector

Yes 43.5psi is 3 bar. GM runs 4 bar pressures.

OP, my 850cc injectors were at 85% IDC on the 578hp pull. I'm on E85 so as long as you are running meth, I think the 1000cc injectors will get you to your goal.

so running more pressure makes the injector smaller?. 95lb per min is roughly 1000cc thats at 43.5. bumping pressure to 58psi would technically make it like a larger injector

if yours were 850cc they prob were not 95lbs per hour as 850cc shows equivalent to 80lbs per min

Where are you getting your logic.... FIC rates there injectors at 3 bar (43.5psi). So I bought 850cc injectors at 3 bar. I run those injectors at 4 bar pressures, making them flow more fuel. So they are really 93.5lb/hr injectors. If the OP buys the 1000cc injectors then they flow 95.2lb/hr at 3 bar (43.5psi) and 109lb/hr at 4 bar (58psi)

no different than what im saying

if you bought 850cc injectors those are 80lbs per min, if you crank pressure they are capable of pushing more. Im just using the RC site for converting CC to lbs per hour

I guess this just confused me. Its the opposite. Running more pressure make the injector flow more fuel in the same amount of time.

New flow rate: sqrt(New Pressure/Old Pressure) * Old Flow Rate

sqrt(58/43.5) * 95.2 = 109lb/hr @ 58psi base pressure

Yea now i realize what you are talking about. Originally you said why not buy my 95lb per hour injectors and then he said 850cc was to small

So i was just stating that 95lbs per hour is roughly 1000cc not 850cc. I think we just pretty much both confused eachother yet we are on the same page lol

Different units and pressures make things confusing to talk about. haha.

for sure man. sorry to clutter up your thread. im trying to get my 05 finished soon, i have sooo much to do
