Did Keystone explain why flat top pistons work better than the pop ups with their turbo? They should be able to tell you what their testing or the customer experience has been.
Typically, with turbo charged or super charged gasoline engines the concern is for spark knock. The high compression pop ups will have more compression than the flat tops and therefore more prone to spark knock. That is not bad, it simply means you have to run higher octane fuel. The pop ups require a higher octane fuel even without the turbo charger.
Certainly, Keystone is recommending a minimum octane fuel for use in your tractor with the flat top pistons...they have to tell you that. If the minimum octane recommended is 89 then running 91 or 93 with the pop ups should most likely be okay assuming a small increase in compression. However, if Keystone says use a minimum of 91 or 93 octane fuel with flat tops...then you are looking at race gas for the pop ups. That is not bad, it simply means you have to use race gas.
Your best information should come from Keystone based on their testing or maybe they did not do any testing....?
