Why Dyno ?

A dyno test is the only way to actually set the timing and jetting of the
engine to their optimum settings. You can gain 5% to 10% in HP easily, just
by getting the ignition and mixture perfect. A side benefit, particularly
for race engines, is you get to break in the engine in a controlled
environment, and you know that when you show up to run, the engine is going
to perform for you.

I found the new link:

I have a GTech and it works good enough - it's just not practical to
test small (5-10hp) changes to see if it really paid off or not...

I also have an AutoTap for my car - I haven't tried it yet but it can
record to a laptop from the VSS - I should be able to map acceleration
vs rpm and build a HP graph from that.

A chassis dyno is just easier than trying to find a good stretch of road
where you can stop, setup and rip off a 0-60 run...
