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

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!

 

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.

 

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.

 

I would say that's a logical concern, BUT if you take the ECU out of the equation, you've got a throttle body and a bunch of sensors, that, if you're hand was forced, should be able to be made to work with just about any other ECU. Now, it won't be plug and play, but it would allow one to upgrade an older system. The ECU just sees voltage from the various sensors, compiles that information, and translates it into a fuel map based on those inputs. So theoretically, you could take a throttle body and sensors from Company A and wire it to Company B's ECU and make it work just fine.

 

FFI technology is so much better than carb technology
Why hide it
the way I see it, this is hotrodding at it best

 

Moon Eyes EFI 3x2 and a Mega Squirt ECM should get it done...

 

Carb technology really is not that bad. What makes it bad is that modern fuels are not designed to function at atmospheric pressure like you find in carb float bowls.
