Moteur Model Engine ASP Radial F400 AR Etape 18 UPGRADE

Introducing the new CNC-machined "upgrade" rear intake flange for ASP/SC/PH/MAGNUM F400 AR Radial 5-cylinder engines. Direct intake of the fuel-air mixture into the crankcase provides optimized lubrication for the crankshaft and valve train, with five intake ports for each cylinder. It installs directly in place of the original flange without modification, reusing the original brass guides and gaskets. It allows the engine to run on a 7% oil mixture. New CNC-machined aluminum "upgrade" rear intake flange for ASP/SC/PH/MAGNUM F400 Radial model engines. The intake mixture now flows directly into the crankcase for improved lubrication (conrods, camshaft, ball and needle bearings, piston crowns, and sleeves), and the intake pipes draw the mixture directly from the crankcase. Installation requires absolutely no modifications and reuses the original carburetor pipe, intake boots, and intake manifolds. Less weight (30 grams), Better lubrication and corrosion protection for all internal metal parts, you can now use a methanol fuel with only 7% lubricants (5% synthetics + 2% castor oil)
