Why???, please answer WHY you are not on the front page of HotRod, CarCraft, MotorTrend, etc, etc, and have your own TV show on speed channel considering your the only one in the world who can obtain these gas figures......... Why are you not a Kazillionare.......sh** even ford would pay billions to keep you hush hush.......that is if you could back all this MPG up with proof......example, HotRod, CarCraft.................................................................................... ....not typing on the net....." I got 444 MPG driving a engine with 1.000.000 miles on it, all ya need is dual exhaust and adjust the carb....theres you proof guys, I just typed it....
Tedy: Hot Rod Magazine, about 3 years ago, did thorough test of the different types of exhaust systems, moving from one to the next system on the same car, on the same dyno, with results calibrated to constant climate. There was, on their test vehicle, a very distinct difference in the horsepower and torque curves, and their conclusion was that if you keep your foot out of it, the same thing that increases your horsepower will increase your fuel economy, namely a freely flowing exhaust system that scavenges correctly. Again, it depends on how you drive, but the very things that will increase horsepower through ease of breathing will also increase fuel economy. Try it. You might be surprised what can be done.
I'm not questioning weather or not a dual exhaust will help a car, MikeT. I'm questioning what I and others would love to know....... How do you and you alone on this earth are "claiming" to get 30-40PMG in 351 and lately 400 Ford engines with zero, nada, none proof what so ever? Back up these claims with PROOF, don't avoid the question A member proved rite from the blue ovals mouth the expected MPG..... no responce from you, MikeT. You MPG claims some how remind me of this......substute engine where they say bun and MPG where they say beef http://www.youtube.com/watch?v=Ug75diEyiA0 The last coment from the old lady..."I don't think anyone is back there"
I've had my Hemi Dodge truck since late 2004. Quad cab. Short bed with fibreglas cab high topper. That should help. We added duel exhaust just behind the cadalitic converters and glaspac type mufflers. Still waiting to see any fuel mileage increase. Changed the big bulky intake plastic boxes, air cleaner box, and tubes to a simple short modern cone type filter and shiny chromed plastic tubing. Still see no increase in fuel mileage. Rerouted 16 spark plug wires according to the pros for better performance. (I question the pros being smarter than the engineers who designed it?) Replaced perfectly good regular spark plugs with four prong plugs which cost four times more! (Again, the pros spoke) One plug tip fires one charge of electricity. Four fire one charge of electricity) One bang for the buck! The gas mileage has remained basically the same since late 2004. This is small town city and highway mileage combined. On our annual migration 1000 miles north I do see a one or two MPG increase at 70MPH. 55 stay alive but get there late! On the average the little digital computer thingie shows 14.9-15.1 I drive sensible but don't baby it. Yet don't put my foot in it like my kid does when he occasionally drives. Haven't changed or added a chip, which is supposed to help a lot. I'd be as happy as a lamb if I got close to 20MPG.:confused: 30 or 40 and I'd giggle all the time I drove it. And I still wouldn't want a hockey helmet!
A single pipe exhaust is better than no exhaust. What did ya find? I've heard situations where a single pipe is better.
Well I humbly submit this: Unless you are going to spin your engine to 7500 RPM or sup3rcharge it, a properly created WYE into single exhaust pipe gives you better torque without horsepower loss and weighs less and is less complicated to set up. Oh yeah.. and its no less fuel effecient than a dual.. and no... no mega mileage either.
I agree about the diesel. If you use a 94 to early 98 Cummins 12 valve with bosh pump engine out of a dodge. It has good torque and you can run it on almost anything oil based. Have seen people change the oil and pour it in the fuel tank, also brake and trans fluid ever used fry oil just run it through a filter and pour in the tank. The engine will burn it and not care only thing is if it's cold outside like up north in the winter you have to put diesel fuel in there to keep the mix thinned out. With this you be able to find fuel for your vehicle much easier.
A possible idea (depending on what you build0, get an old military multi-fuel engine. Burns diesel, gas, or even jet fuel. Far as that goes, find an old commo deuce & a half. Already has a box on the back you could convert to a camper.
If you go down the page to where it says 'van variants', you'll see what I'm talking about. Based om the M35A2 deuce & a half. Had a box on the back fro the commo (communications) dept. http://en.wikipedia.org/wiki/M35_2½_ton_cargo_truck
SO you are saying that if it is liquid oil that cam be pumped.. a diesel will burn it? Would not the dissolved metallic solids in the crankcase oil and transmission fluid crap up the injectors? Would it not need to be filtered? What about tank sediment? SO, If I run the fuel ( as such as it is ) through a double engine oil filter then all should be good?
Zombies dont drive... getting their license down at the DL Bureau doesnt work.. the flash scares them and trhey go on a feeding rampage..
