Howdy
all,
Well, I took a couple
intercoolers to the hanger, and tried them on for size. The FC model would
probably go in the right cheek, without too much effort, though I'm worried that
I'll pressurize the back of my radiator and oil cooler if I let too much air
flow through it. What to do, what to do...
I also did some more
research on charge temps, and intercooler effectiveness. It seems that 70F
is about the best temp drop that you can hope for with a good intercooler, at
high boost. Unfortunately, size counts, and neither the FC nor FD
intercooler is what would be considered "good". Adequate might even
be a stretch, especially for the FD model. In the scheme of things,
<=70F really isn't a deal breaker, and I'm starting to believe it falls in
the category of refinement, more than necessity, when talking about 10 psi
or less of boost, particularly when the higher boost is only used at frigid
altitudes. Turbo Tom considers it a necessity, but I have to wonder what
his criteria is. If I had a car, and were limited to X psi of boost,
I would consider intercooling necessary to make the most power possible.
Since I should easily have more power than I could ever need, I don't see
the intercooler being quite as essential.
What does this all
mean. Well, I'm going to fly it like it is, and use up to 5 psi for
takeoff. At altitude, I'll go for the gusto, but will try to limit
myself to 50" MAP, or 12 psi of boost over ambient, whichever comes first.
This should make a world of difference, and I can move on to something
else.
Cheers,
Rusty
