Just a Thought.. EFI on a Flathead???

Now this is what I’m talking about!! I’m even digging the extra details that I would never had thought about. I thought the engine in your’34 was about the prettiest I’ve seen, but this one is a sight to behold

 

One of the Snipers we installed was plumbed as returnless. I used an LS regulated filter at the rear of the car and ran the supply line to the Sniper. The return from the filter went back to the tank. Capped off the regulator at the throttle body. The filter is regulated at 60psi and the Sniper worked just fine in that configuration.

 

Thank you. The "art" of my cars lies in what is not seen by the observer's eye. All the toys and twists I have hidden are what sets my cars apart from the m***es. It requires a lot of planning and creativity to pull it off. I never thought the HAMB would allow me to discuss it. I hope Ryan lets me renew my membership this summer.

 

Oh Lordy I didn’t even think about that……This might be the way the boss weeds out the “Rats” Oh Meeeeeeeeeeee

 

Holley is the only EFI system to use. All these other brands are not worth the trouble. For a carb replacement, use Holley Sniper EFI and be done with it.

 

I have no personal experience with any of these systems but I do ask people what their experiences are like when I see they use them. A friend of mine in Canada took a 6-pack set up off of his big Mopar to put a FAST system on, only to put the trim-power back on when he had persistent issues that couldn't be rectified. I also have a buddy in Delaware who built a big inch Clev-or Ford engine (Windsor block, Cleveland heads) for his 73 Mach 1, and used a Holley Sniper. It it honestly one of the fastest street cars I may have ever been in. A full bodied, full interior, street trim car with nice driving manners, and can get close to a 10.0 et with the T56 trans. He has no issues whatsoever with that fuel delivery system.

 

I’m definitely going with the Sniper setup, all I’ve heard from you guys and others that has them say they are the best hands down. And thanks to Billy I am going to start looking for a 312 so I can have a cool looking engine bay!

 

And you are very good at it. I've seen LS engines disguised as smallblock Chevy's and most of the time they are easily seen as fakes. The "art" as you put it is in making something look real by incorporating your own creativity and building skills. I plan to use a 2x4 set up atop a blower but it will be injection. Not sure if I'm going to hide it or just be happy with how it looks on its own with a big scoop on top of them. Wanted to use multi-point injection and a couple of gutted carbs as throttle bodies, but I need the fuel to come in above the blower to keep the rotors cool.

But that's the nice thing about injection and its sensors, you can make a potentially problematic grouping of components actually work better if not perfect because you can sense what is needed at each rpm level.....just find a creative way to hide it. Your a talented guy, who dreams about wild projects and likes to find unique solutions....so this should be one more challenge that you conquer.

Converting a Y block should be much easier than a flathead. I imagine you would have the quickest starting and smoothest idling Y block ever. Good gas mileage and added performance as well. Like Billy, find a way to hide the display panel with some fold out part on the dash and you can tune it for both daily driving and an alternate program for racing......best of both worlds.

Yes, I've seen that done before and it can work well. I think as much as we want to attract newer/younger enthusiasts into the group..........we may also entice some of the older guys to consider this stuff as well.



Just pull out slowly guys............. Come along for the ride and you may learn to like it.

 

This is a buddy's Flattie with his own build EFI

 

Any idea what he dyno’d at?

 

Did that on a Chrysler. Like you said, not sure if I'll go through the trouble to totally "hide" it as it's pretty tall as-is and I don't want to cut the hood of the '40...

 

And if you REALLY wanna hide it...

 

I'm not sure if I'd be satisfied with it even if it's an ****og system built in discrete components! I've got an obsession with codelessness. If code wants to talk to my stuff, it can talk to me, and I'll decide whether to p*** on the message.

 

The sensors vary the voltage rather than send an actual code. The computer sends out 5 volts and the sensor only allows a portion of it to return to the computer. Then the computer takes all those sensor voltage inputs and goes to an engineered table and decides how much fuel (and maybe timing) the engine needs. Generally people call the inputs "codes" but its not like you have to be a programmer.
A person does have the ability to change the values within the tables to suit thier purposes, but it's more like putting a different number in a column or row on a spreadsheet.......just enter a different value and see how the engine reacts.

There is a system used in homebuilt/amatuer built airplanes called "Simple Digital Systems" that might be worth looking into. Its more barebones than most systems, but I think if you like to tinker, you would enjoy an electronic fuel injection because it doesn't cost any money to change the fuel and timing inputs like it does with a carbureted engine.

 

I mean, I don't only want to create the inputs; I want to create the operating system! And make the hardware transparent. I'm difficult like that

 

305 Torque, 204 HP

 

Over 200 HP without forced induction, very cool.

 

It's very streetable and he drives it a lot

 

It would be interesting to street drive it against my blown flatty. I make 100 more HP but that is at WOT, light to light is what I am talking about. No lag, power down low, I bet it is a lot of fun.

 

Check out both March and June 2023 Cover Hot Rod Magazine. The 32 and the Hollywood are both his cars.

 

I needed to lower the idle on my PU yesterday and couldn't find the manual so I looked it up on line. I noticed that holley now has their 2nd gen units out that are blue tooth tuned on your smart phone so no screen. While I like that idea I would rather have the screen. Too many apps depend on my phone and if it takes a **** I can't fill my overload bags on my daily, set my home alarm, open my gate, log on to my work computer...too much reliance on that iphone.
But they do have a carb look alike model. The Holley Super Stealth.

 

My only concern is that Holley has made how many FI systems over the years and how many do they still support? Their business model is not great for older, outdated stuff.

Sorry, I'll take this out.

 

I know how it works. That's not the issue, for me.

 

Around 15,000 miles on my sniper. Won't go back to carb. I have 2 other cars ready for it. Need to order one more. Yes it set in the rain. 2 weeks outside.

 

Here is one of my other setups. Hopefully next year.

 

My wife and I took the PU to dinner the other day and the idle speed was 1200 ish. Yesterday I dropped it to 700 and we took it to lunch again, a bit low so I increased it a few hundred. All of this through the touch screen and set up wizard in the LCD screen. No screwdriver or opening the hood required. What is this black art? Oh, BTW, the engine must be at 165 degrees to adjust the idle and you must have the throttle position indicator adjusted within tolerance which I believe is less 0-2.

Weird saying stuff like that on the HAMB. I am ridden with guilt. Does @Ryan have a confessional? Say 10 Our @Moriarity 's for atonement?

 

Yes 160 degrees or above for computer to take over. I drove truck for around 500 miles before it settled on adjusting.
I gained 4 mpg. Starts easy ,runs smooth.
Set it and forget it.
Most annoying thing is waiting for pump to prime. It's only a few seconds.
It won't start up if you just turn the key. Easy to flood. So I wait till screen lights up then hit starter.

 

Now this is plumb ***y!!

 

I'm a believer in continual learning. To stop learning is to begin dwindling away.

 

You might take a look at "Simple Digital Systems" to get some ideas. Its basically for people wanting to use car engines in airplanes. Not suggesting you buy one, but it might give you some ideas.

Or maybe some of the systems that reprogram OEM computers.
