adding CAC to existing dt466 motor
hello im a 40 year gas mechanic and now own a motor home with a 1979 international dt466, have been driving this thing for 4 yrs everything is fine just want a little hill climbing power when towing my boat.
i came across a charge air cooler [brand new] for a good price and from what i have read thought this could be a good idea, i fabricated different inlet and outlet tubes as well as hot and cold pipes, install went pretty well, it sits in front of my radiator and links up with about 2 1/2 foot tubes, i removed the stock cross over tube from the turbo to the intake manafold. before installing i had 15lbs of boost max now i have 10lbs, before you jump to an awnser i have checked for leaks i got ahold of a test kit and tested the thing installed with the hot and cold tubes installed i plugged both tubes and put 10lbs of air in sealled it and lost 1 lb of pressure in 15 miniuts way better than industry standards for leakdown. does this make senceto anybody any help is greatly appreciated
