<div id="yiv2545859906yui_3_16_0_ym19_1_1524306353326_16260">IMHO, you do not want the fan that close to the radiator
because it will predominantly pull air from a smaller area in front of the fan
instead of a distributed area of the entire radiator. The fan blades rear
edges should optimally be exposed outside the shroud rear edge by about 1/2
inch or 10-20% of the blades' front to back width. The radiator needs a
means of venting any trapped air. That is what the small tube's function
was on the stock Tiger radiator, venting to the expansion tank. I know
these details about fans because I designed cooling fans for 14 years for the
Ford F250, 350, V10, Dodge Cummins diesel and many other applications.
Many owners have had a major cooling improvement with the Griffin radiator.</div>
