Will 160's be enough
 

I used the fuel injector sheet above, but I was not sure if it is different for low Impedance Injectors. My goal is to make 1300 rwhp. So I put 1500 bhp in there and it says that I need 150lbs a min.

Again just trying to confirm that low imp and high imp use the same chart.

Thanks in advance!

This what I come up with



Fuel Injector Worksheet

Actual Desired Crankshaft Horsepower B.H.P. 1800

Number of (same size) injectors to be used 8


Brake Specific Fuel Consumption desired 0.65


Maximum Injector Duty Cycle you will see 80%


System fuel pressure @ fuel rail 58


PSIG
(Static flow) injector required @ test PSI of 43.5

158.32 Lbs/Hr 1664 CC/Min

i have made 1100whp with 96's and 2500bhp with 160's.They will be more than adequate.You could use 120's with the right fuel pressure and regulator

I have been talking with a few e85 guys and it's looking like we can see upwards of 1400fwhp with E85 and the right fuel pressure using 160s, but they will be almost maxed out... I think he was around 1200fwhp at 80%DC . Remember E85 takes 30-40% more fuel than non alcohol gas...

I have heard of there being 210s in the bosch style as well, but I dont know anything about them...

Thanks very much, thats what I wanted to know.

"I have heard of there being 210s in the bosch style as well, but I dont know anything about them..."
I had 2 sets on the bench, and found them to be at least 210.. Closer to 230#.
Story I heard was, they were not supposed to be sold, but got here anyway. Supposedly no longer available. They were in the $850/set price range. Last set I saw were $1200.

This is true about the 210's.

And the 150's are now also discontinued and selling for a VERY high price at most places (read $200 per injector)

We still have a couple sets and have them for $79.95 each flow matched.

When you say the right regulator is there a special one. I am using an areomotive one right now. It is also the vacume regulated one also. If I can get away with 120's I would love to

Does anyone have any that they want to get rid of!

I'm running 120's +1000rwhp (T400 automatic) with a weldon regulator(best imho) and the duty cycle is in the low 60's at 55psi base pressure ramped up with boost 1:1. 120's are a great street/strip injector.

When i say correct regulator i mean a rising rate regulator.The 120's will easily supply enough fuel for your hp goals

Thanks, again

Who did you end up going with on your injectors?

At the time I bought them only Racetronix carried the Standard brand injector in a 120lb.

I bought the Trick Flow ones from summit. I could not really beat the price for 400 shipped.
