try the RC engineering 75 lbs hr. ones if you uare looking for low impedance injectors.

He's not a nutcase. :D I dont blame him for needing them. Ran ot of fuel last night while tuning, either my pump didnt support the demand or the injectors went. Either way I think I hurt something. Anyone know of a good dual intank pump out there?
Who has a good set of 60lb injectors?

My 96's were rochester/delphi style, my 160's are Bosch.
I got the 96's dialed in pretty well, they idled very well. Even w/ the base pressure up to 60 (flowing about 100 lb/hr then).
The 160's are still a work in progress ;) But they work.

are these the injectors you ran? http://www.racetronix.com/17113744FM.html
got another question for ya too. i am looking ahead to a set up similur to yours, posiably twin t66's or maybe a thumper. wouldn't the 95's have fed your twin t66's? why the 160's?
is my math messed up? firgure twin 66's = 1500hp max
95lb/hr injectors at 60psi = 100+lb/hr ea, so 800+lb/hr of fuel and a .5BSFC ends up at 1600+hp worth of fuel.
even at 43.5psi the 160's seem prety large? you going larger turbos some day? :devil: twin 76's? :D

yes those are the 96's
Your forgetting RPM in your calc's, not to mention BSFC is closer to .6
At 6k RPM you get 20ms to get the fuel in, but at 8k RPM you only get 15ms. Total flow is not the issue, it's window of opportunity :)
bigger turbo's are already on the way :devil:

thanks for the info, t76's?
the calculators i see dont use rpm for calculating how much hp an injector will support. i wonder if BSFC goes up with rpm? my BSFC calcualtes out to .53 right now.

I just might need those from you. Let me know when you are ready to sell them. Also, did you get the valves I sent?

RPM doesn't figure in to supported HP exactly, but you can't run them past 100% duty cycle. And that depends on RPM.

i currently have delphi 96's after running the mototron 60 highz's to 100% on the last dyno.
a little bit of work to the offset table has brought the 96's to a nice place at 1.3ms and 0% duty cycle at idle and i daily drive on them
