Aftermarket EFI systems.....My practical experience

[DocMel]

Since EFI is/has been a hot topic, thought I'd share my practical experience.    I'm not here to state which one is better, only share my actual experience.  I'll keep it brief, to the piont.......

1.  E Brock multi port w/distro set up: 
   Pros: Ran EXTREMELY well
            Set up/installation fairly straight forward
            Distro conversion was pretty much a direct bolt in
            Plenty of settings to save or choose from

   Cons: Lots of wire looms/hoses.  Allot of clutter to deal with
            Expensive
            No choice of returnless.
            tech support fair-poor

2.  FAST  (1.0)

    -I really cant say anything positive.  I could never get the system to ever run right.  I'm a guy that spends allot of time going over manuals beforr I install, and stumbling, cutting off, and overall very poor performance was the order of the day.  Net forums of variuos types seem to support the same
    -Expensive
    -tech to me was south of poor
    -Wire and hose clutter, large ECU to mount

3.  FI Tech (Go street).  Just installed on my 440.   
     -$800  (Does not include fuel pump, regulator or fuel lines) 
     -MINIMAL wires/hoses, no large ECU.  Installation was as simple as installing a carb.  VERY clear instructions
     -Tech support is very good 
    Was surprised kit didnt come with AN-6 fittings for the inlet/outlet fuel lines, so add another $40 or so bucks 
     -EVen came with a suction cup/stand for the hand held device that programs it  (no lap top needed) 
     RUNS LIKE A CHAMP.  I am talking no burbles, pops, stutters, clean crisp accell/decell and it runs like a modern engine
     Absolutely the easiest set up, basic and and advanced tuning out of the three:  Plenty of settings to save if desired
     Has a returnless fuel option if desired
     I used my existing fuel lines/filters/pump, regulator I used on my FAST 1.0, and no probs
     I would call this system a true "install, spend 5 mins tuning (easy) and forget its there"

My advice to anyone considering fuel inj, whichever system you choose, look close at what is included in the kit you desire:  Fuel lines, pump, regulator, fuel filters can add up to total cost.  I would also highly recommend an in tank pump (although not required) as frame mounted pumps tend to be very loud

Installing the fuel lines, to me, is the most time consuming part

DocMel, I believe the Go Street does have a built in regulator. According to the instructions it's included in the throttle body. When I was shopping for all the fuel line parts for my kit (Go EFI 8 PA) I thought I needed a regulator like the fast kits but then realized it's built into the throttle body. Another cost saving compared to the other kits. 

I'm glad to hear the performance of the Fitech unit is as good as it is. I'm hoping to fire up my motor for the first time with it by the end of this month.

Thank you for the write up. Placing an order soon for FiTech. That way I can start the install while the engine is out getting machine work. Can't wait to try it out.

I spoke to FiTech a couple weeks ago and they confirmed they are coming out with a multi port system for mopars after the first of the year.

When I ordered my kit (February of this year I think?) they said the multiport system would be out in "a couple weeks". If I would have waited to order my kit, I'd still be waiting today. Not necessarily a bad thing considering I still haven't started the car, but just saying you might want to take their time estimates with a grain of salt.

Great info, I'm torn between going straight to Gen 3 Hemi conversion, or dumping money into the old 340 for FI
Any idea what the total cash outlay is for the FiTech system with all the extra needed?  New tank, fuel lines, etc.....

What is a multi-port?   I'm thinking of one for my 383 automatic.     

Aside - Don't these also have the ability to run your timing if you buy a lockout distributor?

Injector in the intake port, also known as sequential fuel injection since it hits each cylinder independently. Fi Tech is nothing more than compressed late 80's early 90's Throttle Body Injection [TBI]. A smarter carburetor. I like the idea and it should be stupid simple to setup, but it is crude and limited in it's capabilities.

But some of the posters are discussing the fact FiTech is supposed to be coming out with port injection...

and? I answered his question.

I looked at FI Tech at SEMA, looks very cool and if I ever go to put EFI on my 52 pickup, that will be what I will use. I have a Holley system (harness and distro) with a F&B 6 pack system on my Challenger and a Fast Harness and distro on my Cuda, since the Cuda isn't running yet I cannot comment on that, however on the Holley system, I would say it definitely isn't "plug and play", however I think it is a good system. That said, I think the EFI crowd thinks everyone going that way needs all the versatility that Holley, FAST and others gives them, however I think that in many cases the simplicity of the FI Tech is more than enough for the casual user. I really like the idea and application of the FI Tech and if it was available in a 6 pack configuration, I would have bought it.

My wife has FAST XFI Sportsman on her '57. When the shop rebuilt motor ... well ... while you're at it.

They run XFI 2.0 on all there strip cars.

I can't speak to install as I didn't do it. But I like port injection vs TBI.  It runs as smooth as new cars. It's got a moderate marine cam. Starts right up. Idles well.

Not sure if anyone has considered this set up. But at least we can give it a  in our experience.

Great discussion - as far as the cost I've been pricing around $1500 all in. $1050 for the 800HP TBI, and $450 for the Sump Fuel tank with inline HP Pressure pump.

Speaking of the latter, has anybody used the inline sump tank. I like the idea of not running new lines and external pump from the tank/in the tank. Should be a simple swap because the low pressure lines will feed the Sump, likely swap my fuel regulator out, and mount the sump bowl there. Then you run High pressure lines to the TBI. Seems to me that if you're doing a long 1/4 mile pull it may drain that bowl pretty quick, but I'd have to imagine they thought of that?

Type FiTech Problem into google search... 99% of all the problems people have experienced are related to the Command Center, which your referring to is as a sump...
