IMO opinion engines have become much more efficient. The only problem is that cars keep getting heavier due to health and safety regulations, which in
turn makes the engine less efficient...
I was in the automotive industry for the past decade or so, and all the "improvements" served was to run the backyard mechanic out of business under
the guise of emission control. Emissions have gotten a little better of the years, but not to the tune of the drastic engine and electronic
I give the car makers big kudos for safety, cars are immensely safer. Everything else is a shameful waste of technology and money!
I hear you brother. I worked in the automotive trades for almost 40 years, in dealerships and service garages, and for myself until the 1980s. It's
true that today's engines are more efficient. Toyota and Nissan uses aircraft technology, and they are very good engines, never thought I would say
that! I wish to touch on a few points here.
Cars are a lot safer now...but at what cost? I remember 20 years ago when a holiday was upcoming the Highway Safety Board would "project" highway
deaths for the day, and then later would compare the two. People got killed on the highway. Population was not as problem then. I know, a little
morbid, but it's true.
Now on the new automobile "technology." Do you all realize that all that useless stuff under the hood is designed to run the engine on a logic
computer with default settings that never change? Do you know that 1/2 of the gasoline you buy runs into the Cat? Did you know that the ignition
system on every car, with few exceptions, will produce only 17,000 volts to the plugs? Older, high performance engines had higher compression, and
high output ignition systems, and very few vacuum outlets to rob performance, one for the distributor advance, and one for the heater controls.
Most new cars have a 4 cylinder engine. These little engines use all of their available horsepower to pull the car along, with very little to spare. A
V-8 engine, by comparison may use 30-40% of available horsepower to do the same job.
I have been experimenting with gas mileage since the long gas lines of the 80s, and have discovered a lot of useful tech that some of you will
recognize. My own vehicle is a 1990 Chevy G-20 van, with 350 c.i. TBI engine and 4 speed overdrive transmission , it weighs out at 4300 pounds wet.
The engine has been rebuilt using only high performance parts, crankshaft tolerances are .003, the bore is stock 4." Flat top pistons replaced the
dished factory ones. the camshaft is a duel pattern cam, commonly known as an "RV" cam from Cam Dynamics, the valve lifters are from Rhodes, they
are three stage lifters that work on oil pressure to produce three settings automatically. The intake is a Holley piece, with a Holley two bbl
throttle body. The ignition system is an Accel ignition module and MSD 45,000 volt coil, and an MSD digital ignition box. We use Bosch spark plugs,
the vales are ground to a three angle shrouded grind. Cyclone headers take away the exhaust through straight through mufflers, no Cat and no oxygen
sensor. The van, with a stock logic computer gets 37 miles per gallon on any day. Our next step is a Painless wiring programmable computer engine
Knowing these things, I can easily see how the man can get this mileage. However, we are talking about building a hydrogen reactor for the van, so we
can run on water. We have these plans:
I know, I know, it cannot work, can it? Well, my uncle has produced hydrogen on the workbench with one of these, and I have seen it work. You can cut
metal with the gas, it burns.
Being a long time mechanic, I hate the high gas prices as much, or more than others do. I grew up in the 60s, and remember when gas was $0.35 a
gallon. America has stored fuel that could run us all for 20 years, but they are sitting on it. We were going to get cheap oil from Venezuela, but Pat
Robertson ruined that. The Middle East oil cannot last forever. so why not invent something better? Some who have invented devices that use other
means to run cars have been killed. I am an old man, I don't care anymore. So I tell everyone in my town who will listen how to improve gas mileage
in the cars, and you would not believe the mileage some cars get! I spoke to a lady at the school on Friday, she had a new Ford SUV. Asked how much
gas mileage, she replied it gets 14 mpg. she was disappointed because the sticker said it would get 21 mpg. Yesterday a lady in a new Volkswagen told
me she gets only 19 mpg. How is the possible? Cars back in the 1960s got better than that! My tailpipe is snow white with a little grey, these new
cars are black and oily. We are Americans, so let us invent!
