    V8 engine Cessna 172

    You are correct. They make really nice dry sumps. My only concern is the aluminum rotors and longetivity. And worst case scenario the belt comes off. The oem ls7 pumps are mounted on nose of the crank.

    V8 engine Cessna 172

    Ls7 comes with a factory dry sump pan and tank. Only rewuires changing the oio pump for the dual inline pump pressure and scavenge pump, the oil pan, the tank and hoses. How much better can you get than oem gm parts for a factory dry sump.

    Reduction drives

    Been doing my research and wondering thoughts of dual mass flywheels. Even though heavy they are designed for the engines harmonics. With the hobmnda v6 there are versions that had single mass flywheels and others with dual mass. When running a psru with an auto conversion would you run a duall...

    10/23 Raptor Video

    Even engine plain bearings would work. You just account for the percentage of oil leak from them. Look at variable valve timing , they use just the cam journals to supply oil to ports in the cam thay advance or retard the cam gear and it works fine. If he copied that system it would work. At...

    10/23 Raptor Video

    Im not going to say funny because no laughing matter. But there are plenty of sealing type devicrs used in transmissions that accomplish this. The seal rings in bmw/getrag dual clutch transmission im working on has everything he needs already made.

    Yamaha Apex internal gear reduction.

    The newer 1.8 engines do not have any reduction drive. Also the 3 cylinder tr1 in the ex and vx line of watercraft that is similar to the 3 cylinder in the yzx side by side. Also keep in mind with addition of a water pump and a new exhaust header the supercharged 1.8 ski engines make 230hp at...
