wow. if i can gain 30hp from new coolant, what if i put in two radiators? that would be like 60hp!!!!!!!!!!!!!!!

no. coolant keeps an engine cool, it does not increase horsepower. if anything, flushing out the cooling system and putting in fresh coolant might restore a little, minut bit of horsepower, but it will mostly ensure the life of ur radiator, and keep u cooled better.

an aftermarket exhaust isnt going to od much for you, and if u think its gonna give u 15hp like it states, im sorry to tell u, but u might get ant the most 5hp. heres what u do. buy some honda performance books and get to reading. go over this forum and several others such as honda-tech and homemadeturbo to see how everyone else makes power. afer all of this, ur gonna realize that u know absolutely nothing and u better keep researching.
