RS Series (Race Spec Power Plants)
The RS series racing engines represent that highest power available: RS4 400bhp RS6 600bhp These engines are only built to order.
Custom built to your specifications in the UK. The RS engine can be ordered new or send us your timed out 320/360/540 wide deck engine and as part of complete overhaul we will upgrade to some or all of our AC Aero AX40 and AX50 Components. AX50 cylinder, rods and piston kits, pressure recovery plenum, light weight oil sump, or many other items we are working on to ultimately replace the dated designs offered by current companies.
Just use the contact form below and email it back, we will then give you an exact quote for overhaul of your engine or a brand new engine built with Genuine Lycoming parts.
Valves, the inlet valve is a chrome steel variety with the back-face design optimized for maximum flow, the exhaust valve is of the “modified” stainless type 1.4882 containing Ta, Nb and W, this allows for higher temperature with greater elongation properties and improved yield and creep strength, allowing a non-hollow design. Both inlet and exhaust valves are designed specifically for this cylinder.
Springs, a single spring of extreme high quality steel that sits on a spring platform that is shimmed to obtain the optimum preload.
Ports, the inlet and exhaust ports are in the same location as a standard Lycoming™ product, however they are of a completely different port shape and design is optimized for the valve size. The exhaust port is fitted with a high temperature sleeve to reduce the uptake of heat from the exhaust to the cylinder wall.
The Cylinder, is drilled to accommodate standard CHT probes, knock sensors, and several baffling mounting bosses. Standard Compression, our pistons offer 8.75:1 compression and 9.70:1 if used with standard piston and ring pack.
