Hello everyone, i have a question I hope someone can help me with, I recently put together a 56 apache with single zenoha 25, and all enforcer guts- I was running about 35-38mph, I added a big bore carb and a dry pipe, problem is I have no increase in top speed at all. I am using a prather 275 prop, I have tried smaller and larger props, didnt do anything, i am stuck, someone please help me get the speed i want, wich is around 45+mph- can this set up get up to 45 or not?? any input will be greatly appreciated...THANK YOU very much, steve...
