This is a great web site on how not to make things :-)

The guy is obviously an excellent fabricator but not a wit
of aerodynamic knowledge was used when designing
this intercooler layout. He needs to spend more time in the library
or subscribe to our newsletter. He is in for some rude surprises
when he gets this thing flying.

It is a shame because a lot of what is on this web site is good.
