Engine Swap

[timvasqz]

what ever you do, you need a designed air path.

conventional flow like in a fc have the fan sucking air in thru the
radiator then over the engine as a secondary cooling.

if you suck air in over the engine to cool the radiator that air
is first heated by the hot engine it passes. pluss the cfm
volumn must overcome the obsticals in the way. If you suck it in
from one side then blow it out the back you leave 1/2 the engine
without any other cooling than water jacket. blowing out both side
puts the hot air back at the radiator. I dont think you can blow it
out the bottom?????

then you have the design of the charge air cooler to consider,
wonder if it was intended to get the coldest air seeing that in
conventional design, it is first to pass air (thats usuly me in big
crowds)

running cooler than 'need to be' has nothing to do with 'running
better'. if it works now, it works

LeroyE once pointed out that there may be some issue or undocument
value of running with and without a mudflap. my thinking is without
a flap, the tranny and tires would stay cooler???????
