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.

Auto Mechanics: Water Cooled Engines: "Water Boy" 1936 Chevrolet 11min

"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...
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.

132702 / 1975 Chevrolet Vega Cosworth
For more information on this vehicle visit http://tinyurl.com/7ls72l8
This all original 1975 Cosworth is one of 2,061 cars produced for the '75
model year, has only 291 actual miles, and has all of the rare and
difficult to find Cosworth Vega parts right where the factory installed
Assembled at GMs historic Lordstown, Ohio manufacturing facility, and
finished in standard issue 1975 Cosworth Vega code 19 black acrylic
lacquer, CV number 1094 is every bit as clean today as when it left the
showroom floor. The car has remained in all original, non-repaired
condition thanks in small part to GMs anti-rust improvements, and in large
part to immaculate maintenance and care given by loving owners throughout
its life. Today, it features an old school factory appeal that you just
can't find in its restored peers.
With 110 horsepower and a 6,500 RPM
redline, the Cosworth Vega was one of the hottest performing cars available
in 1975 and featured a hand-built mill from GM's Tonawanda engine plant
that was individually signed by its builder on a sticker that occupies the
cam cover. Measuring in at 122 cubic inches, and wearing a correct partial
VIN of 40392, this Vegas DOHC inline-four features sturdy forged aluminum
pistons, a heat-treated forged steel crankshaft and forged connecting rods
that both reveal the engines racing ancestry and assure high performance
durability. To meet ever increasing US emissions standards, a custom
designed stainless steel Exhaust
header and Bendix electronic fuel injection with pulse-time manifold
injection, four injector valves, an electronic control unit (ECU), five
independent sensors and two fuel pumps were installed. Thanks to this
revolutionary engine, the Vega was the first Chevrolet car to feature
electronic fuel injection which warranted an HEI distributor for increased
spark and a heavy duty radiator for increased cooling.
At the bottom of this sophisticated Chevrolet, an original Saginaw 4-speed
manual transmission, which wears a correct 338835 casting number and a
correct 15U240392 partial VIN, sends power to an original 10 bolt rear end
that's packed full of stout 3.73 gears. Holding that sports car drivetrain
off the ground is an original F41 heavy duty suspension which includes a
'torque arm' rear end for optimum rear axle power control, larger rear
stabilizer bars, Vega GT springs and shocks, provisions for the Vega's
"fast Steer" option and front disc brakes. At the center of the car, an
original single pipe Exhaust system
snakes spent gases along the floorpan to a factory replacement muffler
which barks an exotic four cylinder growl through two polished stainless
tips. And at the corners of the car, 13 inch British-made, gold-painted
cast aluminum wheels spin correct BR70-13 Goodyear Custom Steelgard Radials
around chrome lug nuts and satin finished Chevrolet center caps.
Take a look inside this pristine Cosworth Vega and you'll find the typical
all business/no compromises black interior that these cars have built a
reputation for. The custom bucket seats, which are completely fresh and
display no signs of wear at all, nicely complement a 100% straight and
crack-free dash. Inside that dash, an engine-turned gold bezel houses a
Cosworth exclusive 8,000 RPM tachometer between a 120 MPH speedometer,
gauges for the engines vitals and a gold-plated plaque which is branded
with the cars 1094 build sequence number. Below those gauges, a correct
radio delete sits next to the cars original heater/defroster; and in front
of those gauges, a familiar black steering wheel is centered behind a blue
Cosworth Vega horn button emblem. At the floor, the booted shifter for the
Borg Warner T10 transmission springs up from like-new black carpet which is
protected by color-keyed floor mats. And at the roof, the cars original
mouse fur headliner stretches tightly around vinyl sun visors and a bright
courtesy lamp. The door panels, which look as good as new, are decorated
with attractive stainless trim and chrome handles for both the doors and
windows. And the hatch, which is lined with the same black carpet as the
floor boards, appears to have never been used.

unique, here's your opportunity to own one of the nicest and most
underappreciated cars on the planet! Call, click or visit
