I know what you're saying....and I'll say this too to remind everyone who
is nitpicking minutia until our deaths (instead of pointing out possible
discrepancies respectfully and just dealing with it).

The problem with modifying a car is that there always seem to be different
formulas that work well together .... those of us in Southern California
who have seen Joe's Pinto run (or XR4Ti-powered Ranger for that matter)
know Joe has an excellent formula. And we do keep in mind that part of the
reason he's getting the times that he does is that the engine IS in a Pinto
.... he's got a lot of work into that car with its rear disc brakes and C4
tranny (and his driving skills). He knows he couldn't do the same times in
an SVO that would still be an SVO (a corner carver) when he got done.

The wall that Joe has hit (as I see it) is at this point what other single
mod does he make that won't screw up his great formula and require him to
make numerous other mods. A similar problem we all have at some point.
There's several different ways to get x-amount of horsepower, and the wrong
add-on or two can prevent us from making more without numerous other changes. 

Example: if we take a stock SVO and add a header (or ported exhaust
manifold). We're not going to see drastic improvemments until we add a K&N
(or other air box mod), flow more air; do a downpipe, make changes to the
exhaust. And maybe THEN we will reap the total benefits of the header.
Maybe it's not a perfect example, but maybe you get the picture.

Unfortunately the only REAL way to test exact formulas (and that's what
some of you want) is to start with brand new blueprinted and balanced
engines and then all things will be created equal. Unfortunately it is not
a perfect world. In the meantime I think we should accept (to a point) and
take whatever dyno runs that ARE done and evaluate that information and
make whatever inferences that can be made until such time someone will
create a perfect world.
