This is a schnieder cammed,ported Vega engine on 12 PSI Boost. It uses a Corvair Corsa turbo in a "draw through" design.
The rubber hose you see expanding and contracting is just a radiator hose we used to fire it up. That is being replaced with hard tubing.
The nasty idle is the cam..I am going to have to run it at about 1000 rmp idle.
Boost comes on at 1200rpm. Any questions,just email me.
I have been keeping Vega engines in vegas for years.
1972 Vega Wagon 1st Drive
Just got my 1972 Vega Wagon going after a lot of work. Currently running
open headers. It has a small block 350 and a TH350 Transmission. 12-bolt
rear-end and 5 lug front end conversion.

"A DRAMATIZATION OF THE COOLING SYSTEM OF THE AUTOMOBILE, SHOWING HOW THE
WATER CIRCULATES AROUND THE CYLINDERS, COOLING THEM AND IN TURN BEING
COOLED BY THE AIR DRAWN IN THROUGH THE RADIATOR."
Public domain film from the Library of Congress Prelinger Archive, slightly
cropped to remove uneven edges, with the aspect ratio corrected, and mild
video noise reduction applied.
The soundtrack was also processed with volume normalization, noise
reduction, clipping reduction, and equalization (the resulting sound,
though not perfect, is far less noisy than the original).
...Cars and trucks using direct air cooling (without an intermediate
liquid) were built over a long period from the very beginning and ending
with a small and generally unrecognized technical change. Before World War
II, water-cooled cars and trucks routinely overheated while climbing
mountain roads, creating geysers of boiling cooling water. This was
considered normal, and at the time, most noted mountain roads had auto
repair shops to minister to overheating engines....
... The subject of boiling engines was addressed, researched, and a
solution found. Previous radiators and engine blocks were properly designed
and survived durability tests, but used water pumps with a leaky
graphite-lubricated "rope" seal (gland) on the pump shaft. The seal was
inherited from steam engines, where water loss is accepted, since steam
engines already expend large volumes of water. Because the pump seal leaked
mainly when the pump was running and the engine was hot, the water loss
evaporated inconspicuously, leaving at best a small rusty trace when the
engine stopped and cooled, thereby not revealing significant water loss.
Automobile radiators (or heat exchangers) have an outlet that feeds cooled
water to the engine and the engine has an outlet that feeds heated water to
the top of the radiator. Water circulation is aided by a rotary pump that
has only a slight effect, having to work over such a wide range of speeds
that its impeller has only a minimal effect as a pump. While running, the
leaking pump seal drained cooling water to a level where the pump could no
longer return water to the top of the radiator, so water circulation ceased
and water in the engine boiled. However, since water loss led to overheat
and further water loss from boil-over, the original water loss was hidden.
After isolating the pump problem, cars and trucks built for the war effort
(no civilian cars were built during that time) were equipped with
carbon-seal water pumps that did not leak and caused no more geysers.
Meanwhile, air cooling advanced in memory of boiling engines... even though
boil-over was no longer a common problem. Air-cooled engines became popular
throughout Europe. After the war, Volkswagen advertised in the USA as not
boiling over, even though new water-cooled cars no longer boiled over, but
these cars sold well, and without question. But as air quality awareness
rose in the 1960s, and laws governing Exhaust emissions were passed, unleaded gas
replaced leaded gas and leaner fuel mixtures became the norm. These
reductions in the cooling effects of both the lead and the formerly rich
fuel mixture, led to overheating in the air-cooled engines. Valve failures
and other engine damage was the result. Volkswagen responded by abandoning
their (flat) horizontally opposed air-cooled engines, while Subaru took a
different course and chose liquid-cooling for their (flat) engines.
Today practically no air-cooled automotive engines are built, air cooling
being fraught with manufacturing expense and maintenance problems.
Motorcycles had an additional problem in that a water leak presented a
greater threat to reliability, their engines having small cooling water
volume, so they were loath to change; today most larger motorcycles are
water-cooled with many relying on convection circulation with no pump...
Jabiru turbo engine walk around and
running with "draw through" with carb. I will try a Aerocarb 45mm.
first start up 460 turbo blow thru turbo sleeper maverick 91mm grabber 73 big block c6
this is the first time it has been started with the turbo it did good it is a totally stock 74 truck
460 only mods are ported exh. side of the heads and a .500 lift summit cam
and arp rod bolts it has a 2 barrel on it just to start it , it will soon
have a 800 holley , just to help some of you guys out the manifolds will
not work upside down the ports are offset between the bolts i will have to
make headers soon for it to perform

Home built electric utility vehicle update
Its the nerdiest thing I have ever built but its for taking to the
campgrounds with the wife because we are too lazy to walk everywhere. If it
being electric helps the enviornment one bit let it be known that I will
sneak up and run over a spotted owl if I ever see one.
I have seats and a cargo box that mounts on the vehicle and the front will

The Unfortunate History of the AMC Pacer
Behind all the jokes and insults, the AMC Pacer is actually a car with a
great deal of history. It began as radical new design from an underdog
company. In an attempt to combat the big, bland, boxy cars from Detroit's
"Big Three," little American Motors Corporation decided to build something
a little different. Their one-eyed car stylist Dick Teague proposed a
small, wide car with big windows and smooth areodynamics. Americans had
never seen anything like it.
This in-depth documentary tells the true story of the Pacer. Unbeknownst
to many, the car persevered through manufacturing setbacks, government
regulations, and many other troubles. Featuring a ton of old car
advertisements and rare footage of AMC's factory, the film helps paint a
picture of the Pacer's world. Director Joe Ligo sits down with AMC stylist
Vincent Geraci, author Patrick Foster, and television personalities John
Davis and Pat Goss from PBS's MotorWeek.
