Doh!! Wiseguy! Well, its not like we were in the big boys of racing where
when they are not actually in the car (which is a vast majority most of
their time) they lounge in their trailer or are out signing autographs or
something. No, we pretty much worked on everything. Hell, I even bolted
the heads on the motor we used. 
Do you wanna hear technical, hows this. One day of testing, (it was
before our second event after building the car) We started having fuel
problems. (Alcohol, not the drinking kind) it would start fine, do a nice
burnout and when I launched off the line, it would stall! 6500 rpm to 0
like that and I would roll about 3 feet. We called in all of our fuel
injection friends to take a look at our car and try and figure out what
was wrong, ect. It took all day long until some little Poindexter looking
dude (That was his name too, we called him Dex.) is looking at a check
valve and then says we have the pill in backwards. (Pill= a little PCV
looking thing that has a little ball bearing in it that acts like a check
valve. its an intricate part of the fuel injection system we were using.)
Anyways, he uses his thick glasses to see this microscopic arrow on the
pill and says we have it in backwards. Flip it around and we run a 8.60
@150mph. 
It don't get more technical than that!

That was my question. What was different about the intake he saw on the
eurovan? it may have had the same size runners but a smaller plenum?

Right, but the variable manifold will give you power throughout the whole
rpm range. If you built an intake manifold to produce the power at top
end then the low end WILL suffer. If you can compensate for the low end
loss and actually gain performance with the use of this overpriced
manifold, then its definitely worth it. even in the drag racing world. 
Id love to see some comparisons (dyno charts) between the stock and
Shrick manifolds. :)
