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 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... Ray |
