Since you guys are such a authority on air flow and depression. I am wondering why wi choose a 500 cfm two barrel over a 390 or 450 cfm four barrel?

Because he knows little about depression..and isn't interested in yours? HA HA He chose the 500 'cuz it's a nice even number, that would be my guess. If he did it to upset you, then shame on him.

Industry depression that a twoo barrel cfms are rated at is double the industry standard depression a four barrel cfm is measured at. Apples to oranges. Give the two yahoos time to raise answere and see if they think 500 cfm at two barrrel depression standard is more than 390 cfms at fourbarrel industry standards. Sometimes what appears painfully obvious really isnt

I read that he was useing a 650 cfm carb with mods. So I searched some old posts and read that it is a Holley 6425. Who's the nit wit now? He isn't even useing the 500 as you assume. |

Ok why did he choose the 6425 two barrel attract 650cfm over a 450 cfm four barrel. I think garry got it when he said you two new little about depression. Proving you guys arent what you say you are when it comes to airflow.

All I admitted was that I have no idea why WI chose the carb he did. That's his business. I know plenty and one thing that I know is that carb he has would flow over 2x what the one you chose would.

Well congrats pankey. You have learned that 2bbl carbs are rated different than 4bbl carbs. The aprentice is learning something.

I'm sorry, I didn't get on here sooner. But it wouldn't matter. By the looks of it pankey doesn't even know what he's trying to argue about.
I had posted some pictures of the tractor over on YT mag forum about a year agoe and he was claiming up and down it's a 4bbl carb. Now tonight he's saying it's a 500 2bbl. Then in this thread Rod pointed out that it was something else. I searched those old threads where I mentioned what it was only to find pankey quoteing everything I posted. So he's seen what it is, read those posts and yet comes on here claiming something else.
So if you ever do figure out what you're trying to argue about, I can answer the questions. But untill then good luck pissin up a rope. Edited by wi50 - 29 Apr 2012 at 2:35am |

pank came lookin for an argument armed with no knowledge. Again.
So pank please tell us why you used a USX21 carb when any downdraft or injection system is far superior. Can you also tell us why you would use a large diameter main berring crank when the smaller one would have less rotational friction? I also see heavy stock Allis pushrods in your pictures,no good for such a high performance application. What is up with those heavy rods with wide berrings when so much better parts are available. Now you know I'm messin with you but next time you try any personal attacks think a little more. I know that you'll never man up to your promise to get running and make us that video, travel around and show us. |

Wi why did you choose a carb that flows less than 450cfms at wot with1.5 hg depression.its a simple straight forward question. Tell rob that updrafts and two barrels cfms are measured at the same depression so cfm speaking a two barrel doesnt have a cfm advantage over a updraft if both are the same cfm.he hangs on your every word.

I'm certain WI knows what he's doing. Weather or not he wishes to share it is up to him. But in reading those old threads he explains why. Once again we have a confused pankey. He's unable to retain information he's already been exposed to.
So why keep skateing around my questions? That carb WI is useing is over 2x the cfm rateing of yours pankey, and would be a much better match to the engine than you had. Don't worry about him. He's been out pulling while you've been lying from your keyboard. I like seeing the refrence to working on your chainsaw. You must have been reading some of WI's old posts on modifying them. |

Its pretty simple the rules said run a updraft.so i did and done some tricks to pull air from other places than the carb that i want share but i am shure you guys know them if i can think of them to do. Oh maybe not i forgot i am dealing with imbeciles.

Oh pankey pankey pankey, why won't you answer my questions?
We all know why. Next time you come on these forums asking questions and trying to insult others rember that some of us know plenty more than you do. Most of us are honest.
Now that you have admitted to cheating. I know that you are not pulling air from somewhere else. Why not show all of us some pictures. You claim to be here to help others, so please do so.
Of course you can't produce those pictures. It's another lie, and will have some bogus answer.
You really don't know anything about WI's tractor. Been bouncing around on carb cfm rateings all over in this thread. But you don't even know much of anything about the engine or what it would require. Your questions are only a desperate attempt to learn.

Pank, that carb I chose is not less than 450 cfm at 1.5" hg. You have no idea what it is or what mods it's had. So you still have no question.
But why did I use it?
For a couple reasons, I could give some scientific ones on carb signal, the benifits of annular fuel metering.
Maybe I used it because it fit nicely, with no fuel bowl on one side it mounts nicely and keeps my intake runner length correct.
But maybe the real reason is that it was really cheap, and with all the money I saved I could pay for pankey to have a psychiatric evaluation, that's $355 an hour with my friend Rockin Rodney Bender....... or any other mental health service providers.
No problem Carl, lust call sometime and we can test those parts for you, and show a few tricks and easy places to gain. I've got adapters made for everything so it takes no time to pull some tests on the flowbench. Saturdays or rain days work best.

rod I didnt admit to cheating . the rule say updraft I run a updraft . nothing in the rule book said everything has to be sealed up tight so i didnt. my motor displaced over 400 cubic inches of air with the throttle closed does yours? carefull the answere could be tricky. Wi you started with a factory rated 650 cfm at 3 hg two barrel .

He also started with a factory 201 cid engine rated at about 30 hp. Has about the same merrit pankey. Please answer my questions, as you seam to be avoiding them. I'll answer yours, no it does not displace over 400 CID with the throttle closed. It displaces 212 CID inches of air with the throttle closed at any one time, as that's the volume of air held in all the cylinders combined at any given point. But displaces a whole lot more air when it's in rotation, so with a CR of 12 to 1 you have a math problem to solve.Why did you sell your parts after promising to put it togather and show us? Why will you not answer my questions?
I have delt with many patients like you over my career. Most of them never amounted to a hill of beans.

I'm pretty busy and don't have much time to check in here, but your math is still off, as are your concepts of airflow.
We would use a simple conversion factor of 1.414 when compareing the 2bbl and 4bbl carb rateings. So you are saying (above in the post I quoted) that the 650 cfm 2bbl flows less than 450 cfm at 1.5"hg. Which is not true, it is really rated about 460 cfm @1.5hg
Above you tell us it's less than 450 at 1.5"hg , but it is not.
The one I was running ran around 730-740 cfm on the flowbench, so in turn would be roughly 540 cfm on conventional 4bbl rateings.
That makes it a real good match for my engine displacement and speed at where I built the other parts for, but then again how good of volumetric effiency can I achieve? I'm dealing with a siamesed port engine, and poor design to start with. I did cut the ports out of the head and build new ones to help, splitting the intake port as far out as I could to prevent overlap, but I can only do so much work in the casting that I have to start with.
It really is a simple question, but not the right question, I never did chose a carb of less than 450 cfm rateing......which is the question you asked.
The diffeerence is that I did not have to get all bent out of shape and insult people.
I'd love to see Rod's questions answered.

Wonderfull post Marty. That is what seperates you two. One of you knows information, has logical reasoning, has the tools, and the experience with these engines. The other is nothing more than a bumbling idiot who has now learned the difference in carb rateings, the conversion factor and that more than a 500 2 barrel carb exists.
Next time pank wants some information he should ask the right questions to start with.
