I have never owned one. However, the stock cooler is good for
about 250 HP. Last year the pole sitting RX-3 used the stock cooler without a
problem. His ducting is very effective and the cooler is in the stock
location on the bottom of the radiator.

By every comparison I
can make, the Setrab 634 is equal to or larger than the stock 2nd gen
cooler. The 650 I considerably larger, so by all rights it
should work for my puny little 200 or so HP. At least, as I mentioned
before, it will have to be light-years ahead of the crappy tube that was in the
Howe radiator. Maybe I can find out this weekend how well it
works.
Thanks
again,
Rusty
