no strange noises. no power meaning it reacts like a slow hybrid, rpm climbs but forward movement and rpm are not matched as normal acceleration for it. it's about half of regular performance. i put it in neutral and floored it the fan was so loud it sounded like a tornado and rpm increase wasn't quite as fast. sorry it is hard to describe other than saying half performance and extremely loud fan when increasing rpm level.
