As far as larry, have you read the update article (on his website, regarding the softhead? Seems to me like he's sharing quite a bit!He makes the point I made earlier, that performance improvements are about improving efficiency, and so are mileage improvements. In fact, even tho he's building race engines, he says his work actually improves the gas mileage.After all, if an Indy car can get more laps out of a given amount of fuel, thats how races are won.Wish I had the resources, (Knowledge/ability,$ etc. ) to incorporate his work, but with the emphasis totally on economy, and performance-wise only looking for street type acceleration and top speeds.As far as emissions goes, he's talking about very complete combustion,=low hydrocarbons, and very quick combustion= low NOX, so I suspect even his race cars might do really well, considering, and a car built using softhead, where the emphasis was on mileage might be phenomenal!Jim

It's been a while since I read any of Widmer's stuff, do you have a link?

I agree that there is a lot of room for improvement, and if all of the effort that has been put into hi-performance had been put into efficiency I believe we would be far ahead of the game by now.

Its on the carb screens thread, by coincidence. :beer: Also, I've added something on my "new" thread.Like to hear what you think. Jim OOps!Getting my own threads mixed up! Look up about 5 posts,on THIS thread, my message to Stranger ranger. Thats the link to the Larry Widmar updat article.Pretty meaty, I thought.
 
I"m a little late on the thermal efficiency portion of this discussion. But I just thought of this and don't know if it's being done or would have greater negative effects than positive effects.

Would anodizing an aluminum head help to insulate the combustion chamber from the head, and also the head from the atmosphere. I know alum. oxide will form in the matter of seconds in atmosphere because the oxide is a problem when welding aluminum. But would creating a thicker layer of alum. oxide through an anodizing process decrease the thermal conductivity of the aluminum at all? And if so, would this help the thermal efficiency?

Also, question about aluminum heads in general, not to derail your thread Divco man, but why do aluminum heads seem to be preferred for high performance applications? Is it because they can transfer the heat faster from the combustion to the coolant? This makes me contradict my initial question, unless you just 'spot anodized' the combustion chambers so that the heat that was transferred to the head is still easily transferred to the coolant.

And now I've confused myself. :oops:
 
Aluminum heads act as a heat sink. They don't tend to develop hot spots that can be the origins of pre-ignition and in general they will support about 0.5 higher compression ratio than will iron heads. They are also substantially lighter and weight is the enemy of performance.

StrangeRanger,
Do you mean that aluminum heads will generally support 1/2 a point higher compression ratio or 50% higher compression ratio. Half a point makes better sense in my head but I'm curious.
Thanks,

"10 or 15 years ago I spoke with a gentleman named Mike Brown who then (probably still does) had the patent rights to manufacture the Fish carburetor. He told me, and no one can likely dispute this, that neither he nor Mr. Fish EVER made the outrageous economy claims that have been bandied about concerning the Fish carburetor."

JW, gotta call ya on this one, at least a little bit. Admittedly, you don't define "outrageous", and the info I got doesn't make specific mileage claims, outrageous or otherwise.

Just got in the mail today some documents I got off e-bay on the fish carb. One is a brochure for the original 'fish' carb, and includes a letter inviting the reader to be an "Emmissary"; basically, multi-level marketing. You try out the product, and if your "sold", you get a salesmans kit to sell to others.On the front of the brochure, it does say;
MORE POWER-MORE MILEAGE-UNIFORM PEAK EFFICIENCY.
"After studying the phantom photo of the Fish carburetor, it is easy to understand why it gets more power and greater mileage out of the fuel used through the entire range of the motor."
In the salesmans kit, he has another of his inventions, actually a great idea;Its called a Fish Mileage Tester. Its a transparent container which holds 1/10th of a gallon,, and has suction cups to mount it to any smooth surface. It has tubing, and a little valve.
"Mileage tester is automatically filled from gas tank.Speedometer reading (actually, I think it really means Odometer)is taken when gas reaches "Start".When gas drops to (2) on scale operator again reads speedometer....If car has travelled two-tenths of a mile on one-hundredth gallon of gas, mileage rate would be 20 miles per gallon."

2 of these are included in the salesmans kit. Overall, as I said, he doesn't make outrageous claims, but its obvious that he's saying his carb will get better mileage than stock ones.

The second brochure is from the "WHITE EAGLE" co. on accesories for the Brown (Fish) carburetor. Says in part; "We handle the popular Fish carburetor which has been reinvented by Mike Brown. You can purchase this item directly from the Brown carburetor co. (address included) or from us. Either way, you will protect yourself from the high cost of gasoline and allow yourself to operate on alternate fuels plus contribute to a cleaner environment."

Maybe Mike Brown had no control over what White Eagle was saying, but it sounds like they were an "authorised distributor", and while they were making specific claims, they were definetly marketing it based on economy. I assume the reference to alternate fuels refers to the claim I've heard that with a Fish carb, you could run your car on kerosene. I don't think they had ethanol or E85 then, although theres no date on the brochure.Maybe by the time you talked with him, he had gotten frustrated with people who thought it was gonna give them 100 mpg, when it was (maybe) giving a 10-15% improvement. And, in fact, he may have gotten tired of the whole thing.

Neither brochure makes specific claims, and I'm sure after the postal service business Mr. Fish had, both he and Brown were very careful NOT to make specific claims, in order to avoid charges of fraud.

Still, theres a gray area between salesmanship and fraud, and if with a wink and a nod you allow the customer to believe what they want to believe, well,...Something like "Look, I'm not gonna stand here and tell ya you'll get 100mpg! If I did, and you only got 80, you could have me charged with fraud, and thrown in Jail! It will definetly improve your mileage, try it and see." Leading someone who's gullible, and foolish, to think they might get 80, especially if you wink or raise your eybrows when you say "80". Anyway, not wanting to start an argument. :D Jim

I would probably spring for one if it actually improved my mileage by 10% :thumbup:

So is this White Eagle outfit currently in business?

If a given engine with a cast iron head is maxed out at 10:1 compression, then going to an aluminum head will allow 10.5:1 compression ratio, all else being equal. This is a generally accepted rule of thumb, YMMV.

On White Eagle, Don't know if they are still in business.Heres the contact info, from the brochure, which isn't dated.
White Eagle
Rt.1 Box 279
East Bernstadt, Ky 40729
Ph. #(606)843-6126
If you do a search on e-bay "Monarch Fish Carb" you'll find an auction for one.Called the guy up and talked to him for awhile.His Dad is 81 and dieing of Cancer. Son never was very interested in Dads business.Apperently, Dad bought the 'Rights" to the Fish carb, he was a machinist, and he did his own modifications to the original design, which are listed on the auction. They also list a traditional fish carb on another auction.Wants $550 for the "Monarch", $350 for the fish. Says the fish's are a pain to keep adjusted, but swears the Monarchs are great. Now that Dads dieing, the son is selling off his inventory, and also trying to sell "The Rights". I assume he means the copyrights to the name "Fish Carb", since the patents would have expired long ago. I don't know whether Dad bought the business from Mike Brown, or from someone who bought them from him.Anyway, unless someone buys it from them, looks like this is the end of the "Fish Carb".
I'd like 1 of the Monarch, just for the historic curiosity, but not for $500! (He'll knock 50 off if you don't want the adaptor).He has 5 or so monarchs left, don't know hoe many Fish's.Jim
