I just saw on FIC's website that they have a Lucas 120lb injector. I wonder how they compare the the SMP 120lbs injector.

It seems as though my SMP 120's don't flow anymore than my Delphi 96's.

Lucas is an old company that was bought by Delphi then SMP.
Lucas has not existed for MANY years.
Why do people keep calling the disc injectors Lucas injectors???
They were redesigned by SMP many years ago.

There is something funny going on with the LSx application. We have a customer making over 1000HP on a V6 with the 120's. One of Champion's customers is running the 120's in an eight-second C4 using a Big Stuff PCM.

I agree Jack something is not right-but Mightymouse is running BS3 and is having the same problem. Even though my DC was 110% there was no issue maintaining my AFR.

Now you mentioned you have the Bosch 1600cc inj. ID discontinued there 1600cc injectors due to failures with temp swings, are these the same?

TIA!

Just to show that our 120# injectors are proven to make good power, and although these are all from the same shop, few people post up thorough mod lists accompanied by dyno videos that are easy to find.

Supra 949.1 WHP & 607.9 lbft @ 25 PSI (94 oct/meth), 1207.3 WHP & 715.5 lbft @ 33.5 PSI (114 oct unleaded). Car is running AEM EMS and an AEM driver box.

Same customers Integra, This car runs our 120# injectors and our Honda injector driver box. 560whp out of a 4 cyl. (Car later made 577whp on pump gas)

http://youtu.be/o1W58FuzDaU

You can do the math on how much hp per cyl they are supporting on those two applications. Again just posting this up to document that they are proven to make good power in other applications.

Something is wrong with them in LS aplications. But dyno #'s don't impress me and I take them with a grain of salt. The track will put the real load on the injector.

There is something being overlooked in the programming or there is an electronic timing issue here. Given the opportunity to do some tests with a DSO it should give us an idea as to what is going on under the hood of an LSx vehicle. We are sure this has nothing to do with the injector itself.

Again, we have a local C4 running them with a BS PCM making some serious power.

BTW load is load and PW is PW.

Before I simplified my setup and got rid of the driver box by going to the FIC Bosch EV14 120s I had the SMP 120s from Racetronix and they both had damn near the same duty cycle at WOT with no changes other than the typical offsets, adders, etc. This means they flowed roughly the same and I never had problems with them.

PW is 18ms, DC 110% at 7200.

Other than that I figure the car is making around 1100 rwhp. It's just weird that 2 cars hare having this issue.

I guess i'm gonna have to try the 1600's.

so you are telling me that supra made 1200 to the tires on 6 120# injectors and we cant make that much with 8?

Dave I went with the FIC 2000's from Jon.

He offered a me bunch of options, one of them was even modifying my 96's, or even get some Hi Impedance 120's.

Give him a call, great person to deal with.

MIGHTYMOUSE

iTrader: (59)

what sway'd you to those vs the high z 160's? figure those would be plenty for you?

eb02z06

Jon said the Bosch 2200 are less tempermental than the 1600's. Plus it gives me alot more room to grow.

hurry up w/ results

I got these same injectors! should be here this week and should have results soon! thanks FIC!

I wish buddy, waiting on my motor, heads and new Procharger F1X.

I think you know Nick Yoskin? He's got them running like a champ in his setup. 1500rwhp!!!!

MIGHTYMOUSE

gotcha, im worried that they are too big for minimum pulsewidth of a 366cube engine with a mild cam and 800 rpm idle.

Interested in some results as well. Especially idle characteristics and tip in throttle response.

stevieturbo

At least check, but ideally log fuel pressure under load. Or if the car isnt currently driving, have one or all of those 120's sent off for independent testing.

Something is very badly wrong there.

But if the 1600cc or 2000cc are a straight fit, they work and have ample headroom...are they really that expensive given money spent on the rest of the car ?

Dave give Jon a call, I'm sure he'll work with you.
