GLADIATOR™ 344ci / 390ci
Individually and custom built for each and every customer. We can recondition your existing Lycoming 320 & 360 engine and convert to a Gladiator™ 344ci / 200hp and Gladiator™ 390ci / 220-265hp.
Air cooled engines are usually run rich during take off and climb, it is not unusual to run some air cooled engines at BSFC’s of .65 and even more if turbocharged. Liquid cooled engines can be run at best power without the need to cool the engine with fuel. By running liquid cooled cylinders we can close up the tolerances and thereby reduce blow-by gases and harmful emissions, at the same time realizing higher output due to better detonation margin.
Advantages of liquid cooling:
- Increased power output
- Lightweight design
- No airflow and baffling cooling difficulties
- Uniform cooling, no shock loading
- Reduced oil consumption
- Lower emissions
- Lower fuel consumption
- Increase in detonation margin
- Better and lower wear
- Longer Service life
