Thank you Bj couldnt have said it better.My jeep has it and it is great. why would you want to put something on that sucks oil into your tb is beyond me. do the little experaments i mentioned,go to a salvage yard and get several of those box sytems and try those different ways and see which works best.I promise the one that works best wont cost you 300 dollars.
besides hp is for road use,you use more torque than hp off road.torque is what gives you take off power,and pulling power. most of the time you aint getting to the point where horsepower kicks in,you are not traveling that fast.the only time i seen when high horsepower is needed is when blasting through deep mud,the faster the wheels turn and keep traction the better.
