Limited cooling space

[Clarence Wood]

  I used the same technique on my intercooler (1982 Nissan 280ZX turbo).  I forced the air to travel across the top and then back across the bottom by putting a baffle in the inlet tank and also moving the outlet tube to the inlet tank past the baffle.  The original design had the inlet at the top on one side and the outlet at the top on the other side.  I was told that because of the air force that would be generated the original design was better; I just could not 'see' the air being cooled.  I have ran several tests and the cooling aspect is very, very good; I am running the boost at 12psi and have no serious turbo lag or any other breathing problem.
