Hi, will a TD5 intercooler fit a 300 TDI ( front mount ) and will it give more power ?
Surely a larger IC would increase the volume of the pressurised side and cause a little more lag?
Not as much as you'd think.
If you can imagine a drain pipe full of tennis balls you put a ball in at one end, a ball comes out of the other, not the same ball so you don't have to wait for the ball to run all the way through the pipe.
Same sort of thing with an intercooler its already full of air when you start so when it comes on boost you just move the air that's already in there
