How much boost does a M90 supercharger make?

The boost pressure you make on a 3.8 pulley Gen 3 M90 will vary greatly on mods and how high you are above sea level. So it depends on multiple factors. Somewhere in the low to mid 20’s.

What did the M90 supercharger come on?

The third gen M90 first appeared in late 1996 on some Bonnevilles, in conjunction with the introduction of the Series II engine. It’s real introduction appeared in 1997 on the Grand Prix GTP, Bonneville SSEi, Regal GS and a few more obscure models (i.e. Park Avenue Ultra again).

How much HP gain from supercharger?

A supercharger is connected directly to the engine intake and could provide an extra 50-100 horsepower.

At what RPM does a supercharger kick in?

The supercharger begins increasing intake air pressure just above idle. Between 2,500 and 3,500 r.p.m. both blowers work cooperatively to boost the intake air to a regulated 22 pounds per square inch above atmospheric pressure.

How much boost can a stock 3800 handle?

The n/a motors are proven to easily handle 6-7psi of supercharged boost without any problems, while the stock L67’s cant handle much more than 10, so it works out right when comparing to a turbo setup.

What does a M90 supercharger fit?

The M90 unit is designed for gasoline engines from 3 liters to 5 liters in size. The M90 may be used in other sizes, depending on the application requirements. It is designed for passenger cars and truck engines.

What cars came with M90 supercharger?

The M90 is designed as original equipment on three vehicle types. It is used on the Ford Super Coupe car series, and the General Motors 3800 Series L67 and L32 engines. The engineers at Ford and GM rely upon Eaton’s expertise in the design of the M90, and incorporated it into their engine designs.

What is the best supercharger?

The two best brands we use for these types of setups are Procharger and Paxton. These superchargers do not create heat as much as the roots blowers. We’ll get to those in a minute. Houston weather isn’t very “roots blower friendly” which means the centrifugal superchargers stay nice and cool so more power is made.

Can a supercharger be turned on and off?

A Weiand supercharger can’t be turned on and off in real life, but so what? However, there is a commonly available supercharger out there that has an air-conditioning-compressor-style electric actuation clutch: the Aisin blower used in U.S.-market 1994-1997 Toyota Previa minivans.

Why is the Eaton M90 called a supercharger?

M90 Designation. When an internal combustion engine pulls in air, it loses horsepower because of the effort. A supercharger, being an air pump, pushes air into an engine. The amount of air Eaton superchargers moves is in the name. In essence, Eaton superchargers are designated by the amount of air it pumps.

What are the specifications of an Eaton supercharger?

Specifications of the Eaton M90 Supercharger. Eaton is a large and well-known manufacturer of superchargers, and provides specifications for its M90 series. A supercharger is an air pump bolted to the top of the engine, and driven by the engine’s crankshaft. Because it increases air pressure, horsepower is increased significantly.

How many cubic inches of air does a supercharger move?

In essence, Eaton superchargers are designated by the amount of air it pumps. For the M90, it moves 90 cubic inches of air per revolution of its shaft. Suppose an engine is turning at 1,000 rpm. With a pulley, the supercharger might be spinning at 1,500 rpm.

What does a supercharger do to an engine?

A supercharger is an air pump bolted to the top of the engine, and driven by the engine’s crankshaft. Because it increases air pressure, horsepower is increased significantly. Unlike a turbocharger, no transient time lag exists until it “kicks in,” so horsepower increases right from engine idle speed through the engine’s rpm range.
