Force Fuel injection in Miami FLa..TopSportsman916 said:Jerry, who made the sensor set up for you? It looks good. Who is the rest of the build coming? If you are like me. it's slow!! :lol:
My 160lb/hr injectors are gray, and came from Ford.
Green is usually 42lb/hr, but it's usually a brighter green than that. I've never seen a 160 that color.
Also, if you want a starting point or want to swap notes about injector pulsewidth, I might be able to help you...it's very critical not to wash the rings when using squirters that big.
Make sure your low impedance injector driver is supplies a full 4A peak current to open the injector and a 1amp hold current to keep it open. Some of these injector driver boxes don't do this...and with the 160's, it's imperative or you will not achieve the short-duration response you need to make the engine idle. You have 2000+hp worth of injector there...making it idle lean requires sub-1ms pulsewidths, and anything other than a true 4/1 driver won't cut it...I've been there.
Also, if this is bank fire, keep in mind that at WOT as the rpms get high, there are short periods where all 8 injectors will see 4A peak EACH (32amps total)...so don't skimp on wire gauge. Most guys build their harnesses from 18ga or smaller wire. This is not appropriate for this type of current consumption. Mine is 16ga and I have a voltage drop on the injectors when they're all on. 14ga would be better...and the main feed going to the 2 banks should be more like 12 or 10ga. If there are any connections involved between the injectors and the harness, check the current rating...make sure you have at least enough connector for 40A or you'll have a problem brewing there as well. I actually melted a weatherpak connector rated at 30A peak.
The car will run if the harness isn't optimal, but injector response time (idle mostly) may suffer. I can't idle mine down below 850 or I get into a gray area where the injectors don't reliably respond.
Those 160's, with proper wiring and control, respond as fast as 0.3ms with 40psi of fuel pressure; and even faster if you drop the base pressure. I run mine at 20psi; I have no need for a true 160lb/hr flow rate.
