My low impedance 120's are hitting 110% duty cycle with meth. I'm kind of surprised because I thought 120's could support alot more power. I don't know how much power the car is making but it runs 160mph@3600+lbs.

Now I need to have a rail pressure of at least 52psi to get the fuel transfer line to work so the saddle fuel tanks work properly.

What injector will work fine for a daily driver, I can go either way low or hi-just want the best injector.

TIA.

whats your fuel pump set up?

also I had smp 120's that flowed less than my 96's so stuck with em.

FIC has an injector affordable enough to 'try' but i have some other things to nail down first.

Hey David, running Lonnies twin 255 setup-the boost referenced pump is going to be replaced with a 340lph unit.

I have the Racetronix 120's. I have hard time believing the 120's are done, especially since I'm also spraying meth, but there showing 110%DC and running at 18msec at 7200.

I don't know if I should try the LI 160's or the FIC 160's or the ID 2000's.

Since I'm running the stock pcm I need an injector that can work with my 55 psi rail pressure.

The good thing about the ID's is they come with all the data-the price tag is pretty steep though!

High Impedance FIC 160s will work. Or if you have the budget, ID2000s. I have the ID2000s on mine, plan on making 1100ish on e85. I can get you a better deal on the ID2000s.

We have the 1600 cc BOSCH high Imp and the 2000 BOSCH high impedance with all adapters on sale for the week for $999.00 for the 1600 and $1080 for the 2000. These are brand flow matched sets that are directly from BOSCH.. prices are for the whole set. we also have the Bosch 160 lows and Siemens 220 lows.

are you able to log fuel pressure? either they arent 120's or they certainly arent acting like 120's

im at about 93% duty on my 96# injectors, 50# base pressure and 1 with boost (25#) and trap/weigh a bit more and of course also use methanol.

Dave there from Racetronix and say 120lbs/hr right on the side of them. I think I saw somewhere where you had some 120's and they didn't flow anymore than your 96's. I used to have Delphi 96's before these 120's-I'll have look into my logs and see what they were running at.

From Precision's site the 120's should be good for 200 horsepower each-that 1600 horsepower.

I wasn't logging fuel pressure but my VE is pretty consistent so i'm pretty sure everything is working. I will be logging Fuel Pressure and Meth pump pressure this season for sure.

I agree with you-if your getting by with 96's something is wrong here.

I just checked my logs from back in 09 when I was going 155 int he quarter. I was using Delphi 96's back then.

My duty cycle was 85% with and the inj were pulsing at 14.4msec at 7K.

These 120's are pulsing at 18@7200 rpm.

I'm not sure if this is a tune related issue or what? Are all 120's the same? These are the Standard Motor Products.

ID2000s , they are expensive, but they are worth it to me. I have the ID725s in my setup and i'm at ~70% duty cycle, peaking 6200 rpm

you could have 120s rated at 58psi (4 bar) instead of the 3 bar rating ?? maybe??
that would make them 104LB/hr at 43.5psi

I don't know about that... are you running a FPR?

The id2000 is an off the shelf injector, you can buy the same thing for half the price. Why would you pay an extra 1000 bucks for them to rebox something. It's just beyond me how the power of marketing works.JMO

Were are these available and is the injector data available for HPT?

ZL1Killa

iTrader: (17)

I believe they are bosch injectors?? and do they provide the data directly?

MIGHTYMOUSE

iTrader: (59)

same **** i dealt with, put the 96's back in, or better yet buy mine!

im gonna get somebodies injectors that work and its not gonna be the 2000 dollar ones, 6-700 is reasonable and they are out there just gotta find the right company to send em to me.

eb02z06

iTrader: (18)

Tell them to send you 2 sets Dave, I'll take one as long as I can get proof that they work with the stock pcm.

I can't believe someone hasn't sent you set already. Maybe they only want "dyno queens" to have them.

Are these the same 160's that FIC is selling?

Does FIC provide the HPT data for these? Will they work with a rail pressure of 52-54 psi?

corpserodeo666

iTrader: (12)

Yes and Yes. I have those injectors and FIC gives you the data for them.They just needed to be adjusted to my car a little bit. But once you put them in they are great. Plug and play. No need for driver boxes or anything like that. I've had them for about a year or so and they have been awesome! My pressure is sitting around 54 right now.

not sure if you guys have liked FIC (fuel injector connection) on facebook. but they have just recently began dynamically testing all there injectors! which basically means there is no difference between ID and them now.. i will be running their bosch 2000cc injectors.

Scorch, Z06wanted is running the ID1000's and when I compare his logs to mine with the LI 96's it looks like the 96's flow more.
