s10 ls1ers
I live in vegas and i have a 2.2l with a 4l60e that was just rebuilt... i have paper work from the shop that rebuilt it... The motor has 86,000 miles on it... it needs the plugs and wire's changed and the oil pan or the rear main seal is leaking oil... but the motor is all torn out... so thats not hard stuff to change... Ill let it go (engine and trans) fro $800 i just pumped $1700 in the transmission rebuild so thats a steal... If you are interested let me know i can take pics and tell you more...
if my calculations are correct, yes.
480hp * 0.5bsfc = 240 lbs/hr / 8 cylinders = 30 lbs/hr / 80% duty cycle = 37.5 lbs/hr
i would say that if you tune it well you can lean it out using less fuel thus needing a smaller injector

you calculations are wrong son!!!
dont you understand that duty cycle is directly related to the size of your wheels? and if your wheels are 15's then the circumfrence of your harmonic balancer is not going to let your injectors fire when the temperature of the powersteering fluid reaches the optimum temperature. thus meaning that your exhaust is too small and you need new tires.

That seems like a hella large injector compared to what everything else is doing even with stock injectors and fuel systems. Perhaps the Brake HP fuel consumption is less than what is normally thought? I mean 380 at the wheels is approx 460 on the crank give or take @ 20% loss for an auto. Still though I did the rough math and I figured that I should have like 35 lb injectors in my truck. Others who have the same cam I do are running good on stockers. Heck need to figure out what the fuel usage is. I'm gonna guess that if a stock 99-00 fbody with the 26 injectors are good with full bolt-ons we can assume the stock injectors are good to 360 flywheel hp at 80% duty cycle. That would give us a fuel consumption of roughly .46 This is just a guess though. If you want to guess 400 flywheel hp is the limit of the stock 26 injectors then you have a fuel consumption rate of .42 units of fuel per hp. This would put the stock 28.8 injectors at a limit of 430 hp roughly. Gotta know what the fuel usage is first I guess, because this is all just a seat of the pants best guess.

i could be wrong here, but this is what all my research has shown.
i do agree that the stock injectors are pushing great numbers and the calcs seem a bit high
i also believe that we dont know what individual engines are using for fuel consumption. i used 0.45 to calculate for my injectors. the calculation is based on how much power you make, which we assume this number... then were guessing fuel consumption... oh boy, what kind of math are we doing here? =]
unfortunately, i have not yet tested any of this on my truck yet.... =[

haha funniest **** ever made no sense yet flowed soo good!!
Hey guys, I have basically read the whole thread here. Lots of info there. But I have a couple of questions.
My friend has a 97' 2wd S10 shortbed. It has already been fitted with a traditional small block chevy motor and a 400 tranny. It is a ladder-bar, coil over setup with a 9". The cross-member has already been nothced in the back to make room for one of those huge 7qt. race oil pans. And it has SBC motor mounts in it. All fits well with no issues.
We are wanting to put a LS1 motor in it and was wanting to know if it would fit if we just bought the motor plates for the LS1? Also should I go to Speartech to get a harness made for the engine comp? It only has to run the motor and alternator.. NO power steering, A/C, heat, guages. This is gonna be mainly a track only truck, it might see a little bit of street time.
Thanks

The motor had a severe nitrous mishap.. And I can get a LS1 for real cheap, so we are gonna go that route. A heads/cam LS1 in that truck, it would fly cause the truck is gutted and is LIGHT.
