Underdrive pulleys

HI!... Actually this RANGER has never been on the dyno. Never said it was. My other vehicles have countless hours on the dyno, either chassis or engine dynoes. To me 1/4 mile times tell everything I need to know. I used to data log on the dyno. But my new set-up, I can data log on the street which is more accurate. It gets more real world data. You have no rolling or wind resistance on the dyno, and more of a true LOAD factor. I might throw it on one day for giggles though. lol!

oh got ya. i misread it. i just thought it would be interesting but i agree with ya on the real wold performance

Ok my 2 cents take it or leave it. when it comes to any engine the better the flow in to the cylinder and out the better the numbers. so yes open up the in coming air and the air leaving but it is only as good the smallest bottle neck along the way. my credit being a diesel tech and two gens of techs before me in my family. oh ya working with a couple different pull trucks.
