Ahh, a refreshing touch of quantitative data.  It's great that you also
dyno'd a WBX for comparison.  I'll be looking to correlate my G-Tech data
with what you've posted.

If you do any quarter mile or 0-60 work, please post it.  The weight of the
van would also be helpful.  I'm working on a simple best-fit mathematical
formula to approximate HP on the Westy.  Having a few engine combos and
dyno data is quite helpful.

And just for fun, how about doing a mileage test?  I've followed a few
posts of late on re-gearing etc on the yahoo subie list and I'm sure there
would be joy, grief and consternation at your results.
