Horsepower/ TQ rating
How much horsepower and torque could i expect on a 4.8 with an air raid intake tube, modded air box with K&N, descreened maf, throttle body spacer, hypertech programmer? Hard question i know but does anyone have this setup?

ur MAF 'seperates' the air going through the sensor and reads the amount going into the engine...so the computer knows how much fuel to add...without the screen to 'straighten' it out its a mess.
what makes u think a throttly body spacer will do anything? it 'spins' the air...i guess uthink the 'tornado' adds 10hp to huh? spinning air won't do anything...it will spin for the few inches until it hits the intake manifold and seperates into the runners to go into the combustion chamber...at that point it isn't spinning anymore.

And its not about "spinning the air". Giving the fuel time to atomize is where spacers on carbs are so efficient. Why do you think alot of drag guys run tall deck intakes, because it give the fuel more time to atomize before it enters the combustion chamber.

On my past 4.8 it put down 235hp and 245tq with a volant cai and a magnaflow muffler I've seen HPP's add about 13hp and around 10 lbs of tq to the wheels on 4.8's and 5.3's.
