Water Wetter does work.  I used it in my racer, also and when the cooling
system is maxxed out, it raises the Max a significant amount.
   Vanagons usually don't have an over heating problem...unless something
isn't quite right...In that situation, Water Wetter might be worthwhile,
but normally they seem to cool just fine without it.   Can't hurt, I
guess...but at the track you aren't running glycol
antifreeze/coolant...usually just water is required...so water wetter has a
real purpose...it helps plain water exchange heat better...in an antifreeze
mix, probably not so much..
