Today Kitfox Aircraft announced that Rotax has just released their 916iS ... 160HP, 2000 hr TBO.

Sounds like we have another option. The planform is similar to the 915iS. Same displacement (bore and stroke), same rpm ... so where did they find the additional 20 horses.

Turbocharger, stainless steel exhaust

Dry sump forced lubrication with separate oil tank, automatic adjustment by hydraulic valve tappets

Intercooler

TBO 2,000 hrs
