120's are done-need something bigger for a DD
#81
EDIT: Just got off the phone with Jon (Fuel Injector Connection). He is running the 160s in a big nitrous motor with a sheet metal intake and no issues and has yet to see a problem with these injectors on an LS car. However, after talking to him for a good half hour we determined I am way over-injectored with the 160's (due to me using pump and meth vice E85). Jon is overnighting me a set of his new 120s to throw in and do some testing on. I will let everyone know what I think of these new injectors. Should be cracking 800rwhp on the low boost street tune.
Here are the new dynamically flow matched injectors. They flow 127 at 58psi and are NOT converted CNG injectors. Nice thing about these is they're compatible with all fuels including Q16.

I'll be running 93 and meth as I can't get E85 here. Wonder how much of an impact the E85 has on keeping those injectors in check.

Its not a moot point at all, because they had no idea there was an issue until ID recalled them. The fact remains that they do not have as much knowledge about these injectors as they claim they do. I think that they would continue to sell these injectors today, if ID had never found the problem first. This is based on the fact that they still sell these injectors, and recently had a group buy LOL. They are hardly steering customers away from them and if anything, trying to unload them onto customers.
Hell when I first starting to talk to Jon he offered to flow my 120's and upgrade them to flow more-I'm the one that said the fug it and send me some 2000's.
He was trying to save me money, and help me out to see what's happening with the 120's.

There is NOTHING wrong with the 120's. The problem lies in the control system. To determine what the problem is we would have to use a DSO to monitor the injector PW vs. the commanded PW vs. the actual injector on-time using the same PCM/driver/wiring configuration. An on-car test would be required as well.

Either the injector works for the application or it doesnt. If it doesnt, why is it sold for that application ?
Ive had similar with RC750s where they didnt offer me any more fuel than the old 600cc Siemens I had. The only difference being they performed worse at lower rpm's
It's ultimately why I opted for using 16 x Siemens injectors as finding a single injector that was big enough and worked well enough a few years ago was almost impossible.

I think it's fair to say we shouldnt have to change the control system just to make an injector work in the vehicle.

The 120's will work with the proper configuration/programming.
The RC750 (SMP 01D129x) is a slower injector than the Siemens/Continental FI114961/2 so the dynamic fuel delivery per PW will be lower and the idle characteristics will not be optimal in some applications.

I recently purchased a set of SMP 120s used from a member of the Turbo Buick community for my Ttype. I know they're 120s because they say 120 LB/HR right on the side of the injectors. They work perfectly on E85 when I use my 72 LB/HR gasoline chip. How can that be? Because they are 30% larger than my 72s.That puts them at 96. Is there something wrong with our three cars? Only when we install these injectors.
The reason I asked you about part number and a picture is because I can't find any info on these with a Google search and they are different in appearance than the current SMP 120s offered at Racetronics.I have to think there was a mis-marked batch and we got screwed. I found out today that my injectors were made by SMP and a search led me to this thread.
Now for the big question. Is the part number 250R160A with a 0600 printed above the part number? Is the plastic upper half of the body black and rounded on top with a stainless steel lower half that is squared off?

If they walk like 96s and quack like 96s,they're 96s even if they have 500 printed on the body.

You say your injectors have 120LB/hr printed on them... honestly, unless there is a part number and a record of everything I wouldn't even believe that, albeit apparently they are 120s but I don't believe it nor like it when **** gets changed from the manufacturer as it then start to become this black hole of he said she said and this form says bull.

You've misunderstood my post.They say 120 but they definitely aren't. I'm having the same experience as two others in this thread. I called FIC and he said that he was unaware of any problems with these and he definitely had the same injectors as mine in his hand. Says many ricers have used them .I would like to find out if the ones the OP is talking about are the same type I have. I can only find pictures of the new design(Lucas looking) when I Google SMP 120 LB/HR injectors. My injectors look like the 19.8 and 20.5 injectors on the Racetronixs site.

As we stated before there is nothing wrong with these injectors. This is a driver control issue and/or something with the LSX control algorithms.

The only thing I haven't determined is whether or not his injectors are the type I have or your 01D134x.
