Ferrea valve seals are made of rubber compound material for intake application and special hi-temp compound for exhaust application.
Victory’s titanium valves have been a mainstay in the racing industry for over two decades in applications such as drag, dirt, oval, marine, karting, Formula 1, road racing, and more.
Manley Pro Flo valve designs are available in the Severe Duty series of stainless steel valves, the “Race Flo” for moderate competition and the economical “Street Flo” models.
Manley’s Extreme Duty valves have been a mainstay of drag racing’s top Pros for decades.
Just keep in mind your application, your rpm range and horsepower goals. The valvetrain puzzle falls into place from there.
When it comes to engine cooling, the radiator is kind of a showoff. It sits right up front, catching the best breeze, dominating the conversation. And when it erupts in a cloud of coolant and steam, everyone knows about it. However, the engine valves (particularly the exhaust valves) shouldn’t be overlooked for the role they
The valves and seats in an internal combustion engine play a central role in engine breathing, compression, performance and longevity. It doesn’t matter if an engine has two, three, four or even five valves per cylinder or if the engine is gas or diesel because the valves all do the same thing: they open and close to allow air into the cylinders and exhaust to exit the cylinders.
If you’ll recall, in the January issue, we got into the nitty gritty details of what makes a camshaft the “right” camshaft. In this issue, we’ll continue the education. Cam class is back in session! Remember the camshaft makes one complete revolution (360°) while the crankshaft rotates twice (720°) for a complete engine cycle. Camshaft
When it comes to engine components working together, there are few areas that share the same level of relationship as the valves and valve seats. The factors that affect this duo’s ability to reside in harmony inside an internal combustion engine encompass everything from material compatibility to thermal conductivity. In regard to the actual physical
