Technical So here is a question for you induction gurus or even

Guys that have hopped up new direct injection engines, have put another nozzle in the intake runner. So far no way to work with the inchamber nozzle. As far as throttle bodies, These came from a 4.6 Ford SOHC of around '02 or so. Many, many of these things out there. These are on the Plymouth. I have a bunch and would sell you 2 for $20 apiece + shipping. But you can probably find some cheaper at a junk yard. A Potvin blown Hemi in a Model A sedan would look way cool.

 

LOL I am on my way to mow as we speak.

 

Hey

Pot in setup is a thing of beauty, and I wish more people wound run them. And with the help of modern technology, part hilborn and potwin set up I bet you could make both streetable, pull a trailer and go 12sec.

You could even talk to some youngsters about how they do modern 4 banger boxers and if you can keep you self from ringing there small pale necks! LOL

Detroit Diesel made a water to air intercooler for the 2 cycle V8 and bigger 71 and 92, and some of the them running blower and turbo had two intercooler!
There might be something available elsewhere for stuff like this, offshore and truck do stuff in a way, that some guys would claim can't work at all.

 

yes Detroit made a intercooler for the factory diesels they were monster things , and either used external water for cooling ( boats ) or used the engine cooling system from the machine it was on , as it cooled the charge down to under 230* ( air to water works better than air to air ) but most stock detroit blowers are sloppy internally as they were originally just for scavanging , not extra horsepower , for that they turbo'd , a race blower the internals are way tighter so they have to be liquid cooled and sealed . do not know if the potvin can be run dry , have to ask the manufactuer as if liquid is needed , your going to score the inside of the case once it warms up if you run it dry .

 

and Beware of Lippy !!!!

 

Stimpy,
Potvin mainly supplied the drive, and there were other builders who also made drives like the Potvin. pretty much all of them get called a potvin setup even if they are not, and it is more easily recognizable when called that even if it aint. There was one company that actually made a potvine style setup with a gear box so you could change to under or overdrive. I saw one a while back on here but I don't recall who made it or even if anyone knew.

And yes Lippy is from Kansas and if you aren't careful he'll get lippy with ya. Of course that's way better then if he got jiggy with ya I suppose.

 

I know of Lippy from somewhere else , the guy is a hoot . funnier in person

 

I am pretty sure we have met and he must be alright because I don't have a bad memory of meeting him.

 

Had lunch yesterday with Charlie and Tim Markley. Also Don Jackson and Bob Dalton. The subject of fuel through the blower came up. You may know Don makes that sort of thing. Mostly for fuel cars. But anyway, his word was 90% through the blower. Port nozzles are for small changes on that one cylinder. But he is not talking about a Potvin drive. He is talking about cooling and lubing the rotors. Charlie has a shinny new looking 10:71 on the DeSoto. Tim's new lakester frame and engine were there. As usual fantastic work.

 

That is good information although a pic of the "unusual fantastic work" would have been nice.

Anyway now I know that through a roots type of blower you need coolant and it may as well be fuel charge. I was aware that Don was involved way up toward the top of huffing and injecting. Although we are not familiar with each other.

Uh next time bring a camera.

 

That was the first time I have ever been to the Markley shop. Known Charlie for 38 years. But never hung out. Might be another 38 years before I get back. Don't know if I have that kind of time. PS That was "Usual" fantastic work. Which is not "Unusual" for Markley-Hoffman projects.

 

What I think is coolist about Don, is that I believe he is The Don of Don's Boxed Rods. Charlie drug one out yesterday and they critiqued it.

 

Unusual usual can be the same word if you are mildly dyslexic. I just screwed it up and having been around for a while I know that any fantastic work is unusual.

 

I can do it, technically.

Functionally, the problem is finding a head, that fits a useful engine, where there is a straight shot into the combustion chamber, that won't collide with springs, valves, guies, etc.

 

I stole this from the 2015 street rod nat. thread. Some interesting stuff going on, no idea if or how it runs.

I was noticing the blow through carbs, not really seeing any fuel into the top of the blowers. No idea what the little tank mounted in front of the carb is for.

That little tank is water, no doubt some sort of a surge tank for the cooling system.

 

I happened to be standing next to that right now, he's local and it does run.Let

 

Let me know if you want to go look at it ben

 

That's Leroy Holler's Hudson Coupe, He builds some really Wild stuff here is a pic of the other twin big block piclup he built a few years back.

 

Wild is a word I'd use lol

 

The intakes on that hemi where they used with fuel injection in some ether application?
It appears to have bosses in the correct spots on the runner for injectors?
Maybe they are for laughing gas?

 

You lost me on this one. Can you be more specific?

 

In this photo if you look at the intake runners are bumps in the middle of each of them
About the perfect spot for an injector
So i guess my point is that these manifold may have been used or designed to be used with injection?
And these manifolds seam to be specifically designed for use with a front mount supercharger?
Also if you had the superchargers internals coated like the m62 eaton buick used on the 3800v6 in I think the 1995 riviera would that stop scoring

 

OK. I squinted enough to see the bosses cast in to the intake logs. I would guess that that is a place where you could put port nozzles. When Chuck Potvin first made these kits a lot of people used carburetors mounted on the blower intake. This particular one has the throttle plates and nozzles on the inlet side of the blower. The Eaton blower is a different animal from the GMC and it's clones. The GMC builds heat by friction of the air flowing back over the lobe trying to push it in the engine. I know that several people have thought they didn't need fuel in the blower. The ones I know, have decided they were wrong. And I don't see what the advantage would be. You beat up the fuel droplets that much and they are bound to be better atomized.

 

Vary true.
know this pick is out of place but i have always loved the idea of better atomization

Now here is the current way of mounting a blower.. No sissy 6:71 here. 18:71 for these guys. This engine runs no water any where. 60 PSI boost from just off the start to the 5. All most all the fuel runs through the blower. But it has down nozzles under the valve covers to each intake. What do you think Beaner?

 

Makes one hell of a racket when you fire it up, too!

 

Should be louder this year. 525 inch motor replacing the 498. And Bob bought Nitro. If he gets to run. Hoping for WoS or the Cook meet now.

 

Crazy. Should get up and go pretty well with that setup.

Now, if nature cooperates.
