Ed A.,
Another question if you will suffer
it.
The stock 2nd gen oil cooler has a volume
somewhere around 200 in^3.
1/3 heat load to the oil
2/3 to the water
Using a core that is 9in long X 4in thick yields a
cooler stack height of around 5.6 200/(9X4)=5.5555 to
equal the stock cooler in volume (granted it may not be as efficient at 4 in
thick, but it is also moving at 200+ mph something the stock cooler was not
designed to do)
There is a really nice SINGLE
PASS 4in thick evap core that has a core area of 9X6.375
with tension straps and heavier end plates.
This is a volume of 229.5 which is around 15%
greater than the stock oil cooler.
If I use 3 of these, one for oil, and 2 for water
do you think I am pushing my luck a little too far?
Seems like it should work if the duct work does
it's job. I have a little more freedom in shaping my diffuser and exit than you
guys because I am not working around the engine and an existing
cowl.
At first they seem a little small, but when you
stick them together it is a cooling block that is 19.125X12X4 with the tanks
(19.125X9X4 without tanks) which doesn't intuitively seem so small for something
going 200 mph.
Trying to save having to drill the baffles
out, plus money, plumbing, and weight.
I think there is another 2 pass cooler somewhere
between the 8in thick and 6.375 thick model that may be a bit more
conservative.
What do you think, have I lost my mind on this
one?
