John Everything looks pretty nominal for your set up. Do you have an thermostat in you cooling system or not? The reason I ask Is while 190F if fine, but if you are current producing 135-145HP and put a 2.5:1 on it and end up producing 200 HP then your may find Your temps are going to go over 190F. Now if you have a thermostat holding it at that temp, then it may be that you do have sufficient capacity for more HP. 200HP in a tailwind? Boy, you are going to blow most things in the sky away.

Your temps are going to go over = 190F.  Now if you have a thermostat holding it at that temp, then it may be that = you do have sufficient capacity for more HP.  =

 

200HP in a tailwind?  Boy, you = are going to blow most things in the sky away.
