Pulled our truck and the Freighttrain without and then with TC lifts. Tried a 3" block and it seemed better than stock but we both settled on a 2" rear blocks & liked that best. As for limiting upward travel of the front. We tried that also, We had 6" of air underneath the front tires & bent front end parts on both hooks. We couldn't get that stuff off quick enough. Just my opinion though. Air to water? Just checked my pics & that was so 2008 :roflmao: Dyno results did not confirm enough of a gain for me to screw with it. Who needs an intercooler for 300' anyway, it's only a parts catcher
Im probably going to stay air to air this year, as some of the associations i pull with dont allow w2a, and i dont want to change back and fourth. All the tractor puller guys ive talked to says w2a and how good it works all has to do with the size.
