Well to explain a few things im running an airplane fuel pump to help force enough fuel when the turbo hits boost. And the turbo's exhaust compressor is ported large and smooth for full flow and yet enough to spin the wheel at a sufficiant rpm to make power. Had a problem at first, not enough blades on the exhaust wheel, so it didnt hit boost till the end of the motors rpm's. So i added 2 more blades and that cured that problem. And yea your half right about the boost blowing right through the motor and out the exhaust when the pistons down but when it comes back up i snag at least an estimated 45% out of a 100% plus the insane amounts of fuel im dumping at the same time create the extra hp i was hoping to get out of the project. And the reason for the liquid cooling is because i figured that since i was going to ram some air into this motor that i might get a rapid change in head temps so i stopped that problem dead in its tracks with the liquid cooled idea. And after all said and done didnt even notice the measly amount of so called weight that i added to my truck.
