What injector do you recommend for 1200-1300 RWHP on E85? Using stock ECU on a 2000 camaro.

Are these injectors a single cone or dual cone spray injector?

I have these in my car but have only made 727 rwhp through the 4L80e unlocked.

FIC, how often do you recommend them to be checked when running E85? My car sat for 6 months with the same fuel in it. It ran ok for a few weeks but I recently started having a lean issue and sent the injectors off to be looked at. I completely forgot you guys check them for free, but I sent them to a shop locally who also sells your injectors.

How have these held up? Thinking about trying a set.

Mine are doing fine in my stock PCM'd Turbocharged LT1. I drive back and forth between Albany and Rochester NY every week, 249 miles each way, and it still gets 21mpg on that trip driving at 75 in 6th. Yet they will deliver way more than enough fuel underboost. I'm still fine tuning WOT at 15psi. Not sure if my pumps are keeping up. I'm checking the fuel pressure during a pass this weekend. I've got everything in my 2 bar SpeedDensity tune spot on elsewhere. I have to play with the injector constant to be within the VE ranges in order to get the 100kpa fuel I need. I would definitely recommend them.

What's considered BIG power? I made 935 rwhp @ 83% inj duty cycle

whats your base pressure?

58 psi

So that's through an auto with 58psi base pressure?


I have a 6spd vette running these 127lb injectors at the same whp and I'm hoping they can take me to 1,100whp.

I'm running a magnafuel 4340, so not sure how much I can crank the base pressure before running out of pump.

What's the most e85 power made on these injectors?

boostedc20

I could be mistaken but I think that 127 lb rating is at 43.5 psi and they can flow more at higher pressures.

Any problems with these really wanna try a set

127 @4bar
110 @3bar

Exactly.
127# @ 4 bar (58psi)
110# @ 3 bar (43.5 psi)

Just to be more clear, how much HP are these injectors good for on boosted race gas engine?

mightyquickz28

iTrader: (8)

Assuming 58psi at the rails....
The injector calculator worksheet I see says
NA (Naturally Aspirated) = 80%duty cycle, B.S.F.C @ .50 = 1,625 hp
Turbo = 80%duty cycle, B.S.F.C @ .65 = 1,250 hp

so what would that be on e85 on a boosted motor?

mightyquickz28

iTrader: (8)

Yes.
Using the calculator here...
http://fuelinjectorclinic.com/flow-calculator

Put in,

• Number of cylinders = 8
• Fuel Pressure = 58
• Turbocharged
• @ crankshaft
• HP = 1200
• Duty cycle = 80%
• Click on 'calculate'
• Look at the E85 notation below

Can I run these with my stock ecm.... I was going to put 60 lb Siemens in my car, I have them on the side... But, I really want to spray my blower set up with a maxed out p1sc-1...

What are the 60 lb injectors good for... I think I will have about 700 rwhp when I max my blower out... I want to get 800 to 825 with spray.. Anybody running that power with the 60s. I love spraying my blower set up... Its really makes the difference up in torque, and I dont have to leave like an animal...

Hell, if I can run these injectors, I will spray my motor 250 shot...

Also, I had a turbo Buick, and had a boost a spark on it, same thing as the boost a pump..

I was going to run this on my ractronix fuel pump.. 20 volts to it, at full throttle.. At Kenny Bell, there running a 1000 rwhp on stock pumps, and set ups, with the boost a pump... Anybody running them... I have it, so I am going to run it...
