you are doing your math wrong.
you need to add the number to the crank number.
let's say that there is a 15% driveline loss at the wheels.
I'm going to use the LS3 as an example.
426 hp - 15% loss = 362rwhp
with the LSXr manifold and throttle body it adds 14 hp at the crank.
so that would be 440hp
now 440 hp - 15% loss = 374rwhp
so in reality there is a 12rwhp gained.
but remember the point of this mod is not to gain horsepower, but to reduce weight, heat, and gain better airflow. Which means a cold air intake would gain a huge advantage out of this. So people might see higher numbers with their intakes.
