Comes down to weight and balance. Mark did some mods to his corvair aircraft and gained about 10 hp. On the other hand you could compare a VW powered KR2s vs on powered by a corvair and the weight difference is offset by the increase in power and the fact that your not working the larger engine as hard therefore the reliability should go up. With the corvair engine hower you have to worry about the crank breaking. THe crank issue however has been resolved with the new 4130 crank. Regards Stan
