I'm using a three rotor Mazda in my plane. Since it came with turbos it has the low compression rotors. 9.1 ratio. I can use non turbo rotors and increase this to 9.7. But, I found a company that will increase the compression to anything I want (10.5) and rebalance the assembly. And ceramic coat them. Since I'm not using turbos, I want the extra hp. But I notice most "airplane" motors run very low compression. I'm sure this for a safty buffer for overheating an aircooled engine. So......My question

Any reason I shouldn't raise my compression to 10.5 to one?
(I will be running av fuel)

Thanks
