Jay -
There is a guy here in Detroit that has a really sweet dyno at his race shop.
I will get his name and email it to you so you can discuss what you would like
done. He is a really nice guy and would most likely help us out! I only have
to go through my archives to see if I can locate his email address.

No question that dyno testing would be a good idea if we could get
someone to do it. Ken Brown (former SCCA club racing technical
director) started to go down this road before he was replaced. He
actually got some dyno data that showed that a 493 had 2 more hp (I
think that is what he said). The problem was that the testing was done
on 2 different dynos by different people. So that result is essentially
meaningless. Plus/minus 2 hp is not much variation & is within
repeatability ranges for many dynos. The only way to do this is to pay
a dyno house to really work on this & that would be just as expensive as
car testing. Or we get a volunteer with a dyno to spend a few of days
to do this. Is there anyone out there with the facility & interest to
do this?
Thanks ... Jay Novak

Don't get me wrong, it was only a suggestion in an attempt to get
something
that would satisfy the concerns I saw raised on the list. I wasn't
suggesting that anyone was getting rich on F500 sales! : ) Thanks for
the
breakdown on costs Jay, although it would appear that some of these
costs
have already been incurred since Don has done some testing previously.
Anyway, maybe it was a dumb idea, I've had one or two before! But
maybe
dyno testing would be better, I don't know. It would be nice to get
some
type of comparison that could be shared with the community that is
trying to
decide the acceptance of the engine. If we wait until it is on the
track
(regional or national) there will always be the question of the
influence of
all the other factors (chassis setup, clutching, aerodynamics, weight,
and
so on) on the actual performance.
I know F500 sales are not some lucrative form of business and I respect
the
guys doing the car building. I do see the other side of the coin
though,
and that is the guy paying out the cash for parts, including engines.
If
there is any possibility that a new engine will obsolete an existing one
(one that for many of us does not present a current problem) or reduce
the
value of the existing cars/parts, then it should concern a lot of people
enough to ask questions and seek answers. Maybe the 493 is the best way
to
go for the future and maybe the data from regional races will show no
significant difference in performance, but you can't blame the people
with
money already invested in the current engine not to be concerned. And
with
the number of "performance" changes made to the 494 rave engine I
believe it
is naive to think the 493 will not go through the same cycle.
