What is the maximum power capability of 630cc/min fuel injectors?

Ted.

Thanks for your honest opinion Ted. I should start saving for some new injectors even if that means I go the ID850 route. Is it still safe for me to have the tuner push my car past the 600rwhp mark with the kits 60lb/hr injectors (even though safe is relative and depends on the tune and others factors, but strictly speaking from an injector size standpoint)?

Thanks a ton JLE, I will look into these in detail.

Sorry, that link doesnt connect you to outlook. but that is the email address he will respond to

Thanks Bull. You're the man. I'll definitely be looking deeper into this and sending an email his way. By the way, your car has come a long way bud. Congrats and it looks and must perform amazingly.

I'll definitely talk to the tuner, and see what he recommends and is more comfortable with. Thanks a bunch.

I did a simple proportion math equation and assuming the 80lb/hr injectors (aka ID850's) that you used as an example and those making 1226 at the flywheel (at 80% duty cycle), I found 60lb/hr injectors would theoretically produce a max power of 919 flywheel horsepower. So, assuming a 20% drivetrain loss, a 60lb/hr injector would be able to handle 735rwhp, or with a 15% drivetrain loss would be 781rwhp (these would all be at 80% duty cycle as well since that's what the original example was). Sound Correct (even though this is in theory only)? On fuel injector connection I inputed a BSFC of .65 into the calculator with a duty cycle of 80%, with 60lb injectors we would be at 600 flywheel horsepower, which is 480rwhp assuming a 20% drivetrain loss, and 510rwhp assuming a 15% drivetrain loss. The example and calculator figures differ greatly unfortunately. I'm not sure if I did the math 100% correct, and I'm hoping you guys can shed more light on a subject I'm not as experienced in.

Ted, can you shed some light on the max power a 60lb/hr injector could handle?

How much hp do you want run for sure ?

For right now, I don't plan to go above 650rwhp. I have ADM twin fuel pumps installed thankfully, but now it's up to the motor holding up and the injectors to not be maxed out. I would like to stay between 80-90% duty cycle maximum if possible with these, but I don't know if they'll be maxed the between 625-650rwhp.

I'd say that's about right. We did 925rwhp. and I would guess that was about 80% duty cycle.

TCAT I've got a set of fic 1000's I'll ship to ya for $300.00 machined tip,flows 108lb/hr @58 lbs fuel pressure.....if you want to save about $300.00.just let me know................

I dont think the ID1000s will be enough for my final goal. Just want to make sure there wont be issues with the humongous ID2000s on 800RWHP and dont want to have to buy new injectors with the big blower

We run the 850s at that power level with head room the 1000s are fine also we made over 1200 Crank HP at 60%.

2000s are overkill and need a scaling exercise to work in the E-38 ECM

Actually You want to be well below 80% to leave room for Cold Days.

Now, I in no way want to max these injectors out, so I'm looking at purchasing more capable injectors. This will a least give me room for future power upgrades, but larger injector capability also gives me piece of mind that I'm not using them at maximum duty cycle. Can you recommend what size injectors I should look into for 600+ rwhp applications, and which manufacturer of the injector to buy. I remember reading that Ted Jannety recommended Injector Dynamics ID-850. Anyone have experience with those or any other similar injector?

Thank you!

I think your cutting it close with 60 lb injectors and 650rwhp. I had 52 lb injectors with 600rwhp and I was at 84% duty cycle. Now I have the Id 850s with 655rwhp and 53% duty cycle. I would probably buy bigger injectors before you bump the hp up to 650rwhp. Just my .02

The ID850's are actually a 98lb/hr injector - they are expensive but worth it.

Absolutely, this is my description of ID-850s

INJECTOR DYNAMICS 1025 cc or 96 LB HR AT 58 PSI INJECTORS

[Oxtar41]

I just picked up a set of id850s from ted and i have to say they are expensive but spend the money once on a good set and be done with it. People need to quit taking shortcuts and buying cheap stuff to get by. All that happens is we get more "my motor blew" threads lol. Save up, spend the money on the proper equipment and THEN tune for more power...

[camslambam]

Spending thousands of dollars on engine parts and upgrades and want to go cheap on one of the most important aspects of a build? Cmon... Save up.... Don't drive the car often until you have the correct essential parts.

Thanks LSX, I will definitely let you know when the time comes and if you still have them. I really appreciate the offer.

Looks like I'll be saving some cash for a while to ensure I get some bigger injectors to leave plenty of headroom for cold days, as well as future power increases. Thanks again for all your expertise. When I'm ready I'll buy from you sir. It nice to hear detailed descriptions in your threads and when your provide input. These injectors seem amazing, and I would rather do it right the first time, and call it a day.

I'm thinking the same thing. I don't want to be pushing my limits here, and I want to try to minimize the stress on these injectors as much as possible in all conditions. Thank you for the advise.

From what I've been reading, the ID850's certainly seem more than worth while for the price, and they are pure plug-n-play which is amazing.

I agree, lol. I'll be likely going the direction of the ID850's for my next set of injectors. I want something that will more than suffice for the future, and injectors that will guarantee to work as advertised, as well as provide a safe and easy means of tuning. These seem to fit that description.

Thanks again everyone for the advice. It really has helped lead me in the right direction and put my money where it's worth.
