Everything = looks=20 pretty nominal for your set up.  Do you have an thermostat in you = cooling=20 system or not?  The reason I ask

Is while = 190F if=20 fine, but if you are current producing 135-145HP and put a 2.5:1 on it = and end=20 up producing 200 HP then your may find

Your temps = are going=20 to go over 190F.  Now if you have a thermostat holding it at that = temp,=20 then it may be that you do have sufficient capacity for more HP.  =

 

200HP in a=20 tailwind?  Boy, you are going to blow most things in the sky=20 away.
