gear ratio related to horsepower?

[word]

will my gear ratio effect my wheel horsepower?

such a n00b question.

I'll take a stab at it, I don't think so, what it does effect is getting from A to B due to certain gearing. :unsure:

times two.

Gear ratio will affect how your car accelerates though. 1st gear redlines at 40 mph in my Escort GT, same in my new Si, but 2nd gear redlines at 65 mph in the escort and like 60 in the Si. It just matters how it's geared.

The dyno reads your engine rpms for a reason. Ever notice how you can't get a torque curve without having the engine speed read? You'll just be on a different scale if you don't measure it- you'll have a readout vs speed, and the speeds may be different depending on what gear you chose, but you won't get a torque or hp vs rpm graph. If you are reading the engine speed, then gear ratio doesn't matter.
