High quality, performance and speed!
Made by J.H.P. Motorparts
J.H.P. Motorparts has developed and produced high-end combustion engines for the serious 1:8 model racing. The entire process of design, development and production of race engines for 1:8 scale is done in house. For this purpose we are in the posession of our own facilities equiped with several high-end, specialized machinery.
Design philosopy
Our main goal is to achieve the best ratio between available materials, fabrication technology and the demands of the user of our engines. To reach our targets we are using the latest available materials, a modern production facility and the expertise of our staff. In our view this has resulted in a very light engine, with a superb power to weight ratio in combination with a excellent fuel efficiency and life time.
Materials
By using high grade materials for all the parts even for less important parts we have created a high quality package. Aluminium T7075 T6 has been used extensively. Cilinderhead, conrod, crankcase cover, engine mounts, exhaust manifold and all aluminium parts of the carburettor are machined from billet Al 7075T6. The piston has been machined from billet aluminium containing more than 30% silicon. For the crankcase and cilinder we chose Al 356, a superior material for castings widely used in the racing industry. At last but not least: our cilinder has been constructed as a integral part (AAC) which means that a layer of hardchrome as been applied directly to the inner wall of the cilinder body. A technique widely used in the motorcycle racing industry and a must for high specific power ratios.
