>Four HP on a Vanagon is a lot...

But you aren't likely to see 4hp increase on a stock vanagon.  Results would
be proportional at best likely.  What maybe a hp or two?  Will you feel that
seat of your van pants, I doubt it, doing time on the track sure, but I've
only run a van once for giggles here in WV.
