What is a 350 Ram Jet?
The Ram Jet 350 combines the classic look of the original Rochester mechanical injection system with the dependability and optimized performance of contemporary port fuel injection.
How much horsepower does a 350 RamJet have?
350 hp
At 350ci, the RamJet has 9.4:1 compression, iron Vortec heads with 1.95/1.60 valves, and a mild roller cam with 196/207 duration at 0.050 tappet lift and 0.431/0.451 lift. They are rated at 350 hp at 5,200 rpm and 400 lb-ft at 3,500 rpm.
What is a RamJet car engine?
The Rochester Ramjet is an automotive fuel injection system developed by the Rochester Products Division of General Motors and first offered as a high-performance option on the Corvette and GM passenger cars in 1957. It was discontinued partway through 1965 in favor of the Chevrolet Big Block as a performance option.
What is a Ram Jet 502?
The Ram Jet 502 blends the legendary torque and performance of the Big-Block with a modern port fuel injection system and tunnel ram-style high-rise intake manifold. It’s a combination that offers uncompromising performance – including 502 hp and 568 lb. -ft. of torque – in a visually stunning presentation.
How does a ramjet work?
ramjet, air-breathing jet engine that operates with no major moving parts. It relies on the craft’s forward motion to draw in air and on a specially shaped intake passage to compress the air for combustion. After fuel sprayed into the engine has been ignited, combustion is self-sustaining.
What is a scramjet and how does it work?
A scramjet (supersonic-combustion ramjet) is a ramjet engine in which the airflow through the engine remains supersonic, or greater than the speed of sound. Scramjet powered vehicles are envisioned to operate at speeds up to at least Mach 15.
What are the disadvantages of ramjet engine?
Disadvantages Of Ramjet Engine: It requires a launching device at supersonic speed. It is unsuitable for subsonic speeds. It has low thermal efficiency and high TSFC. Its maximum operating altitude is limited.
Is the ZZ502 fuel injected?
DESCRIPTION. GMP-19331576-1EX – Pace Fuel Injected CPP ZZ502 502HP Fully Assembled Deluxe EFI Crate Engine Includes: Pace engine prep and oil priming service.
Is mechanical fuel injection good?
Mechanical Fuel Injection Is Not Just for Race Cars Anymore Idle or wide-open throttle, there’s no in-between. Great horsepower or horrible driveability, your only options. Since its ’40s conception, mechanical fuel injection (MFI) was strictly reserved for race cars. Street cars need not apply.
What is the minimum speed for ramjet?
A ramjet can theoretically be started at speeds as low as 100 knots but it does not start to produce any significant thrust until the airspeed reaches approximately mach 0.5. Even at this speed, efficiency is very low and peak efficiency will not be attained until reaching supersonic speeds in the realm of mach 3.
How much fuel does a ramjet use?
In a typical engine, 100 pounds of air/sec. is combined with only 2 pounds of fuel/sec. Most of the hot exhaust has come from the surrounding air. Flame holders in the burner localize the combustion process. Burning occurs subsonically in the ramjet and supersonically in the scramjet.
What is the difference between a ram jet and a scramjet?
As in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion (hence ramjet), but whereas a ramjet decelerates the air to subsonic velocities before combustion using shock cones, a scramjet has no shock cone and slows the airflow using shockwaves produced by its …
What fuel does a scramjet use?
Hydrogen
The Scramjet engine designed by ISRO uses Hydrogen as fuel and the Oxygen from the atmospheric air as the oxidiser.
How do ram jets work?
What is a ram jet 350 fuel injection kit?
The Chevrolet Performance Ram Jet 350 Fuel Injection Kit is a retro-fit fuel injection kit that can be used on any small block Chevrolet engine with Vortec heads. This is the same unit used on the Ram Jet 350 crate engine. It does not include the ECU or wiring harness. The same as used on Ram Jet 350 engine – 809-12499120.
Why buy a ram jet 350?
Free Shipping! Chevrolet Performance’s unique Ram Jet 350 combines the classic look of the original Rochester mechanical injection system with the dependability and optimized performance of contemporary electronic port fuel injection.
What is the Rochester Ramjet?
The Rochester Ramjet is an automotive fuel injection system developed by the Rochester Products Division of General Motors and first offered as a high-performance option on the Corvette and GM passenger cars in 1957.

How does a ramjet fuel injection work?
Unlike electronic fuel injection systems that would become common decades later, the Ramjet is purely mechanical and relies on vacuum and pressure signals to measure airflow and meter fuel. In the early 1950s, fuel injection was the topic of a significant amount of research by the auto industry in the US and internationally.
