How well does it run? Are there any tuning or drivability issues with it as opposed to a GM style system with Mega squirt? Any self tuning/calibration issues on a fairly stock /6?

CAn you provide a link to a website for us to look at?

This is the same kit : http://m.summitracing.com/parts/PFS-70021

A friend of mine bought a 70 mustang with this system installed. He wants to convert back to a dual quad set up and said I could buy the FI kit from him for a price too good to pass up.

Never used it. Looking at the directions, it does appear to have a fair amount of flexibility in the tuning; and possibly some brains in its adaptive properties. If it's a good price, it might be hard to pass up. But I'd have a backup plan: what if it just doesn't work? Too much work to tune, or just won't go low enough for a low-output slant? What else will you be out, in terms of money and time, if you try it, and dislike it?

At the very least it appears it needs a four barrel intake.

Have you done any google searches to see what others think? I'm going to go out on a limb, and guess that the dominate users are V8 users, so you might not find any reviews by people running sixes. But what is the general consensus online? Good, bad, indifferent? Usually negative reviews can reveal real problems.

Of the top of my head, 750cfm seems overkill. But on EFI setups the throttle body is less important. I'm not sure how much leeway one has, as I don't think I've read any musings about using a too-big throttle body. I'm going to guess it really doesn't matter, as long as the openings can be made small enough to idle properly (everything else, like throttle opening, engine loading, etc is measured electronically; there's no need for any restrictions to provide the necessary vacuum signals for a carb to work).

Have you looked at Megasquirt's site, in particular for this setup? Often many sites will try to review the competition. Doing a google search on a site can be quite easy: do a search as "site:forum.com proinjection" or similar.

CFM of the throttle body is relatively meaningless as the number means that it will flow "up to" 750 if the engine is demanding it. It only allows air to pass, it does not force it in. The computerised metering should adapt itself.

The big thing to look at is how easily can you adapt the fuel rails injectors to an inline engine?

There are enough guys on here who have done EFI conversions that the little things like pumps/regulators will be a piece of cake to figure out.

Oh, I realize it'll only "flow" what is necessary. I'm just musing why no-one uses a sewer pipe for the application. After looking into it, it appears GM used the same two-barrel TBI for 4.3, 5.0 and 5.7L applications (don't know what the cfm was). But I'm not sure if vacuum drops off precipitously at part throttle or not.

The setup is basically a TBI.
Instructions here. Looks like the "big" steps are, four barrel intake, fuel plumbing (with a return line), O2 sensor install, and finally tuning.

Might be able to use a surge tank on this setup, and avoid running a return line.

EDIT: After some google-ing, I can't find anyone complaining about a "too-big" TBI. So I'll retract that concern, as it appears to be a non-issue.

I did soooome research on it, and wasn't able to come up with anyone that has it installed on a /6. But I've found quite a few ford straight six owners with it and they all have good things to say. One thread I read, a guy has it hooked up to a turboed 270 (? I think it was) straight six running 8 psi boost and the powerjection pretty much right out of the box with good results.

My slant is mostly stock. Its been rebuilt .030 over, stock 71 cam, 73 electronic dizzy, Clifford intake & long tube headers, Summit Ignition box and coil. Right now for fuel I'm running an Edelbrock 500 cfm Carb. It runs fairly well, but I had to go up 1 step on the secondaries and go to Max shot on the accelerator pump.

Edit: installation of the powerjection system should be fairly straight forward. The TB bolts on the same as a 4 barrel and the Ecm is under one if the "float bowls" . Fuel pump and lines are already fairly easy. I ran new fuel lines and installed an electric pump over the summer. It would just be a simple matter of swapping in a high pressure pump and adding a return line going into one of the vents in the tank?

Sdale,

My son, Ryan Covalt is running it on his Slant six car right now. He is on here a lot so drop him a PM. He also was trying to get set up as a dealer so he could get some better pricing. But you would have to ask him more about that.

I know when we went to Elk Creek this summer it got 22 MPG (I think) and it has 4.30 gears with OD.

Thanks for the info!

I picked the injection system up last week. I'm the one that had to remove it, but it only ended up costing me 450 bucks.

I'm going to hold off on the install until I get a new O2 sensor bung and the pulse width modulator for the fuel pump so I don't have to run a return line. I'll be studying the instructions and tuning guides until then.

But all in all, it seems like a great kit!

That is a great price if it is complete. If you want to talk to Ryan, I'm sure he would share anything he has learned with you. Drop me a PM and I can give you his number if you like.
