The reason why I said what I did was for the simple fact that on stock compression the octane wall is around 700whp with 93 octane. So if you don't plan on supplementing with meth or c16, then dropping compression would be required if you plan on going over 700whp with pump fuel.

That being said I would run E85 at all costs and leave the compression alone unless you plan on building a 1k whp monster, then it might be a good idea to go ahead and lower the compression a point .
