my injectors were not "clogged" ,y stock multecs were in perfect working order, and getting me around 18mpg in the city if I was easy on it, and they dynod at 302 to the wheels with just my catback.

I wanted an option for injectors for LT4 guys, so I talked to Jon about making a custom set for them. He did, and I was the test mule.

His injectors look, and perform like brand new injectors, the amazing new partial throttle response, and a smoothness even my father noticed when I pulled into his driveway are all due to them.

do these look like "used" injectors to you?

 

Yes, that's a used Ford injector. It says Ford on it.

 

So ?

 

Right, If the injector works well and you got it at a good price, so what.

 

Yes,no one will put their eyes on the installed injectors and say...."hey,it says Ford on them"
i seriously doubt it

 

Jon sells new injectors too, you know.

 

Ahhhhh....now I see....its not a matter of trying his injectors....its a matter of it being a PITA just to change them.....got it.

I know my car would run better in the 1/4 with the HP its putting out....but...I am running 18 street tires that are made for looks and not traction...then, although the 4L60 is a good tranny, I lose raw engine HP from the drivetrain.

I've already had an offer to put drag radials on, but rain got us...not to mention I was sure I would tear up something.
My tune guy and other keep telling me that a good clutch, standard tranny and drag radials might put me at high 11's....very possible ...the car is balanced very well with the parts. The atomization of the des.III balanced in my mix perfectly....good atomization is basically free HP from the injectors.


See; I didnt find out about FIC from this forum, it was actually all the camaro, FireBirds and several LS guys at the track that mentioned it, since I went from TF, and Accells then back to the Mulls from my other engine...I wasnt about to change to Des.III's....then my tune guy intro's me to some fellows with the huge 4door SS Impala's that was blistering the track...little did I know they had LT1's in those.
After talking to those 4door guys that run 11 and 12's consistently; they told me about a place in GA. called FIC....I searched here, read all the results, and in all honesty, I couldnt find one person who had a bad experience...so, out the Mull's went and in with the Des.III....been night and day since.

As far as used parts?....well think about it...whether we put bolt-ons or complete rebuilds...we are working on "used" motors..."used parts" if you will.
If we rebuild a tranny; we are rebuilding a "used" tranny, same as the rear diff, the engine, heck....we are rebuilding a "used car" if you think about it....so; the "used injectors" didnt bother me a bit as long as it worked.
And like so many others; I have seen people get used parts like alternators at auto-zone or other parts houses and they are junk....but I worked at a dealership and we gave the customer an option of used or new...its the quality of parts and craftsmanship that makes a difference.


Black is the greatest color for a Vette IMO, hard to keep clean.....but I sure do like that dripping wet look of a good Admiral Blue paint job.

OK....carry on.

Kool===yeah...I have had my car custom tuned....first was PCM for less....the motor was fresh, and that was good enough for the time.

Knowing what parts that was in the engine I just started throwing parts at it (bigger #'s and name brand injectors) trying to capitalize on the bore size, the porting of the heads, forced air induction below front bumper, and the cam and rocker ratio...basically; I started going the opposite direction of how I built the motor .....*balanced*.

Then I went to Thunder Racing for a dyno-tune. in-ground DynoJet model 248 Chassis Dyno
Thats where all the info about going to the track for real world numbers, and real world performance, and tweaking came into play. You can do a computer model of an engine and the parts it has; there is nothing compared to proving it on a dyno-jet and actually hitting the track and trapping *REAL* numbers...."estimation talk" is cheap.

So;
I brought all my paperwork with my specs and lists of parts and went over it all with the tuner...he suggested different injectors then, I didnt listen.
Went back to the track I couldnt perform all that well...went back two weeks later after putting the other Mulls back in....went back to the track only this time; I was all ears...got the info and came here to read.....called Jon, ordered went back to the track....I have one more *tune only* session (by appt. only) and I am done...I'll go to the track a couple of more times cause my son enjoyed it, then I am done with that before I break something...I have to refrain from the temptation of the drag radials, its not a race car.

Its just too bad your car is a biotch to change the injectors...I bet the Des.III's and another good tune would really make your day






Jim

 

Work well ? Used? Its remanufactured so it dosent really matters. because you got 3years warranty. much longer then brand new ones.. Accel crap have 3 month and crap Ford got 1 year... and they still dont wanna help you if the injectors are bad..

You wont get any better injectors then Jons injectors.
The Bosch III sprays like no other injector.. And the service you get from FIC is really good. (Phone, 770-888-1662)

If you looking for really good injectors for your car buy these : http://fuelinjectorconnection.com/sh...&productId=134

you will be a happy man if you do.

Dont bother reading the hole thread (theres alot of talking that dosent even mention injectors so...), just Call Jon and he will help you out with your injector problem.

 

I'm planning to get a new tune soon. If the Trick Flows don't work out I'll take Jon up on his offer.

 

Wouldnt it be better to r/r the injectors and tune the engine then?

I ask cause I honestly dont know the parameter characteristics of the L98 and mini-ram set-up.

But...


In my hard-headed mistakes/experience I found that each time I swapped injectors without a re-tune, my air/fuel ratio changed making the computer have to unnecessarily adjust....I even had to clean sooty spark plugs, and a loss of 14.7/1 air to fuel ratio.


So, if I was you (and had the $$$$); injectors and all the gaskets (of course)....and anything that was in reach with the top half of the motor clearer, I would do some "maintenance replacements before failure", just because they were in reach...you know, other gaskets, spark plugs, sensors, spark plug wires if needed, time to look at motor mounts and inspect, hoses, vacuum lines, ect....you get the idea.
That way; a lot of wear items and old rubber has been "freshened-up" while clearance was not an issue.
By the time you are done, it would of only taken an hour or so more to have these items replaced...did I write that correct?
Its just an idea to not have to go there a year or so later for a simple part that takes hours to replace

Then its the new injectors and another good tune....basically; you would be tuning/balancing new fuel parts with new ignition parts if they were replaced (the ignition portion).

Post your results....I know a lot of L98 guys would love to hear how the Des.III's work with your mini-ram, along with all the other improvements and bolt-ons you have already made.

This is basically what this forum is about....those that ask; are hoping to get members with experience to chime in, especially when they have a set-up similar to what they are reading about.
Kool---your testimonial when using the DEs.III's will be very valuable for other members....you could do a write up with your specs, procedures, tweaks, and final outcome for a lot of L98 guys for years to come.

I can write about my 96, but it wouldnt help the L98 guys in so many categories, of course; the OP asked about the used injectors and I could chime in on those.



Actually; this whole thread is a pretty good read....the Des.III's in this thread covered a lot of different makes and models...there are some SS Impala and LS forums with a lot of good info on tuning I read there too when making a decision), and achieving a perfect 14.7/1 after a tune-up, injectors and tuning to those....

ohh...and having headers/free-flowing exhaust, and a good air intake system is a must to unleash all the HP...not to mention fuel efficiency with $4 per gal. fuel....but, everybody knows that...right?

Update -

I had the injectors installed on Thursday and the results are outstanding.

The car no longer backfires. The gasoline smell is gone. The exhaust isn't nearly as smelly as it was before. My gage that shows mpg works again and the car runs stronger, and much more smooth.

Total cost was $190 for the injectors shipped plus $77 for the gasket set plus $250 for my mechanic to do the installation.

The only issue we ran into was that one of the o-rings on one of the injectors had a miniscule crimp and we didn't see that until after the injectors were installed. We had to tear the top down again to replace the o-ring then everything was fine. It added about an extra hours worth of work.

Below is a picture of the new injectors installed.

Thanks for all the help guys.

 

we are glad you are happy. Again, thanks for the business
Jon
