horsepower is just a measurement of heat. How many hp do you estimate your engine is? You stated aftermarket injection, what brand? a 22" 2 row b cool(i disagree) is not going to handle much more than 250-275 hp freeway or not. If it gets hotter in traffic then thats a pretty good indicator that a, you need a shroud and b probably a larger radiator. If it wont come down from 195 then thats about all it can handle. FYI we only used b cool 3-4 times in my shop at customers request, rich jeep guys that thought "more expensive means in must be better ". They all overheated and had issues, then at my insistence, they used my less expensive and not as "race car looking" radiator and fan combo. No more problems at all, never even a thanks! In my experience, be cool was exactly the opposite, over priced and over rated all while being under cooled.
