That's a lot of trouble. We just make injectors that fit with no modification and I'd sell them to you for $40 each.

Anyway that aside, ford does rate theirs at 39 lbs....you buy a 19 lb "Ford" injector it's a 22LB "GM" injector. Same injector rated at different sizes.

And finally.....

There's no such thing as a FORD injector.

There's only a few manufacturers of injectors...

Bosch, Seimans, Lucas, Delphi, Denso...one or two others.

A "Ford" injector is simply a Bosch. There is no difference. Don't pay for a name.

I sell a lot of 160 lb injectors and there was a great debate on the "white" vs "blue" top ones.....bunch of garbage. One was made for Chrysler, one for Ford. No difference between them

All that being said, I hope I helped...... I'll be around a bit.

Thanks.

$40 a piece ? thats $320 for 8 injectors, thats a rip off.

Thank god for FIC and there awesome customer support and good prices

I usually just buy FMS injectors. I don't trust most modified injectors. Spoke with too many pros like Rich at cruzin performance and it's just not a good idea. The guy at FIC melted down on me more than once. I've purchased used injectors from southbay and got a pretty good deal and they worked fine.

that's a brand new flow matched set. No so sure how it's a rip off.

I can do rebuilts for 1/2 that price......

It all depends on who is modifying them and how much experience they have.

Anyone who knows how to do it, it's not a problem

now, I will concede the point that if there's an off the shelf product, then yeah, don't modify. That's not always the case.

Additionally, there's physical modification and flow modification. Well known super chargers by reputable come with injectors, where do you think they come from, they are modified.

Bottom line is if the person doing it is experienced and knowledgable it's not a problem. There's not always an off the shelf solution.

If somebody told you that it's probably because the injectors they got were poorly done, OR they don't know how to tune a car. We put modified injectors on the bench all day long and they run just as accurately as robot made new ones.

I hear you. Just a lot of room for error.

Can you modify TBI injectors? If you could get those suckers to flow 100+ lbs per hour you'd have a market.

This is pretty funny. I make the comment "The guy at FIC melted down on me more than once." I go to lunch, and in my inbox is an email from the owner. Melting down again!

We use a lot of 60lb ls2 injectors for the vettes here in Jersey. I have installed over 50 head, cam mods this year alone. There is no good drop in for the ls2 at 60 rated at 43.5.. The Siemens don't fit[ and they have the wrong plug. I put in the mods from FIC, send him my cores, reset my IFR and the cars run perfect and pass emmisions. I know many shops that use these mods.. We love them, plus it costs a lot less than buying a new set

You can't escape the fact that the guy sells thousands of injectors..

I think I just rub him the wrong way.

Which vettes ? c4? c5?

Hey Joe, btw, do you have any idea who this is????

I am skunk working TBI injectors this week as we speak. Getting them to 100 lbs is one thing, doing it on 20 lbs of pressure is another.

I'll know by the end of the week. We wasted about 6 injectors trying to do it, we're confident it was more about us being tired than lack of ability.

Give me a week, we'll know.

all c6 stuff, there were no ls2 c5's

Didn't know if you were retrofitting cars or whatnot. I don't do vettes anymore.
Bought horses and my money went c-ya..

Absolutely. I'll pick up that imaginary 50 HP...

BTW, you still have that calpack laying around? I'll buy it from you. Sent you an emial didn't hear back. They are getting IMPOSSIBLE to find.

Didnt see any info about brand new thats why I posted the comment, now we all know they are brand new.

HEY! WE DID I!!!

We have tested and verified our new TBI injectors.

These are CUSTOM MADE and gauranteed to work in your TBI applicaitons.

Our injectors come in sizes of 85lbs, 95lbs, 100lbs, 110lbs..

all at 20 lbs of fuel pressure!!!!

Call us for details.

You can not get these anywhere else in the world except IP!


$125 each..

anesthes

iTrader: (12)

So the 110s support a little over 400hp.

How much fuel pressure can you run before they become unreliable?

You should post in the TBI forum. A twin 52mm TBI and these should hit around 400hp no problem.

-- Joe

InjectorsPlus

iTrader: (1)

Great question Joe. We tested them to 30 pounds, ran them 1/2 hour straight no problem

We can get as much as 140Lbs/HR at 30 lbs. We feel confident they will be reliable there. They will become erratic if you go higher.

Doesn't sound like much, but that's a 50% gain in pressure....

anesthes

iTrader: (12)

As long as the spray is not bouncing off the throttle blades and saturating the air filter, it should be just fine.. 140lbs/hr should handle over 550hp.

-- Joe

InjectorsPlus

iTrader: (1)

They spray perfectly at that pressure.

Yep, and it's far less expensive than changing everything over to an MPI setup.

anesthes

iTrader: (12)

My intention is to provide a bolt on solution with guys that have a working carb setup.. Say you have a performer RPM or a victor or something, and want to control your fuel with a laptop but not retrofit EVERYTHING.

-- Joe

InjectorsPlus

iTrader: (1)

I have one of those. 100% made in America. Bolts right up. We have a tune DONE for the 7747, we provide the chip and everything. All you have to do is add the ECU, they go for about $50.



Is this what you were thinking?

anesthes

iTrader: (12)

Not exactly, as that is 4 port injectors. How are you driving those with the '747?

I had an idea similar to that a while back, but for a number of reasons it just won't work.

Merged these posts into a new thread as they were not really related to the previous topic.

-- Joe

InjectorsPlus

iTrader: (1)

Since the 7747 is batch fire, doesn't matter if it's 4 or 8 injectors.

Sure, link me to a place more appropriate.

'747 is usually tbi, which fires bank to bank. You guys modifying them to run batch port injectors?

yep. I don't do it personally. If you want I can get you details on Monday. It works, it's in a lot of cars running around out there.

Joe,

The guys that do this for me have a custom harness. Simple, just plugs right in.

iTrader: (1)

I didn't mention it because I didn't think it applied, but I also have a 6 injector version if you just can't get enough power out of four injectors...

anesthes

iTrader: (12)

I'm trying to figure out how you guys are "making it work"..

I'm decent at tuning. but Rbob is the electronics and ECM guru. If you or him can explain to me how it 'works', I'm interested.

Based on a previous discussion with him, I abandoned my idea of running injectors like that because of the reasons listed in the thread I linked you.

-- Joe

InjectorsPlus

iTrader: (1)

I called and spoke to them, they "splice in" four caps so you get a 2X2 batch fire solution.

Using the big TBI injectors like that how are you going to get around the fact that TBI squirt is per DRP and the big injectors will have too small PWs at low RPM cruise and idle? Can these things go sub-500us PWs?

InjectorsPlus

iTrader: (1)

That is why RBOB is trying them. We don't know. We will find out. If they work, he gets to keep them, if they don't, he sends them back for a refund. We don't have the R&D resources of GM. We're on a budget... That's about $1000 and it's almost reached...

Idle is always the problem with big injectors.

We can do a lot "in theory" but when it comes to implementation, that's where the rubber hits the road. And remember bigger engines need more fuel to idle, so may not be too much of a problem Bottom line is we just have to see.

junkcltr

iTrader: (1)

I hope it works out. One of the problems that has plaqued TBI is the available injectors.

Yes, fueling modes need to be more advanced with larger injectors (e.g. bank, SEFI)

Not true. Keep in mind the engines with air compressors feeding the intake. We can run a small ci V8 with a tiny cam and still require enough injector for 800+ bhp. Lots of people with TBI want to try turbo/supercharge, but it is the fuel system that always hold them back from making power. I think a lot of these people would be interested in these injectors.

InjectorsPlus

iTrader: (1)

Thanks. I appreciate the input. Just saying that sometimes what looks right in the lab, translates differently in practice. I hope people would be interested. I try to build to niche's...

I just happen to be in the market for a high flow TBI injector now. I have an '89 formula with the stock l03 305 currently that is converted to run on E85 so I run 30psi pase fuel pressure which is about 22 at idle ( for a better idle) since the regulator is plumbed to intake vacuum. I have 2 vortec 350's sitting in the shop now both slated to be installed in the car. The first I am going to overhaul and drop in bone stock as I need to replace my tired 305 soon, and the second will be built to run 450-500hp and swapped in later. The first and possibly the second I plan to run TBI until I can afford a nice MPI manifold setup. I feel that the stock engine will need more flow than the stock injectors can deliver since I am running E85. I could simply go to 454 injectors for the stock vortec, but the modified engine will need bigger than that for sure and 454 injectors are scarce and cost nearly what you are charging for your units. I will be running a 4bbl style intake on the stock vortec with a TBI adaptor since those intakes are cheaper than a TBI intake made for vortec heads and they also appear to have more plenum volume and better runners as well. Also, does anyone think that with the right injector size and a 54mm tbi unit the tbi unit can handle up to 500hp ? If so then I can focus my money on the engine internals and keep the TBI and convert to MPI later.
