Naturally aspirated aircraft engines typically weigh 2 pounds per horsepower. The upright versions are mostly used in trikes, light twins and replica aircraft that require a narrow engine package. Wow, whoever wrote this must be wearing rose colored glasses! The difference between maximum rated power and normal rated power is extremely important to this discussion as it directly affects reliability and TBO. Automobile engine power is quoted as maximum rated power. Torque (T), power (P) and engine rotational speed (N) are related by: T (lb.-ft.) = P(hp) x 5252/N(rev./min.) The engineering in these support systems can be considerable. However, the pump drive system should be checked to see if there are any pins connecting the drive gears to the shafts. You may buy them new from Honda but most customers opt for used engines that have been used in cars for less than six months or 5000 miles. There was a great discussion about the engine on the Zenith Engine page but it seems the moderator was pressured to delete the thread. If sealed bearings are used, they may not reach this life if the hours per year are low because the grease sealed inside the bearings can dry out. No engine will function for long without adequate cooling. Torque (T), power (P) and engine rotational speed (N) are related by: If we choose the aircraft conversion figures as an example: Interestingly, if we check the torque at the maximum power rating we find: which is 7% less than the peak torque rating.
