Finding a dyno that allows for full power in 2nd or 3rd is very difficult, even the loaded dyno's don't generally have enough load. This is why higher gears make more power, especially on turbo motors.

I am well aware of how it works, but nonetheless your link doesn't work.

I have no idea of what you are talking about? Here are lots of people using 3rd gear for dyno'ing. No shortage of dynos that use 3rd gear. In fact, if one has lots of power and a less than stellar clutch, it is the preferred gear so it gives the clutch a little more advantage. It's also a lot safer in autos that can go 150 MPH in 1 to 1.


For the last time. Gears don't make power, turbo motors or not.

This is easy to see:
Remember that power is force times speed (distance/time). Or, more specific for our needs, power is torque times RPM. Changing the gear ratio will alter the output torque , but it will affect output speed exactly opposite, so power stays the same.

Simple example: Given: 1lb-ft @ 5252 RPM. Run this through a 2:1 reduction gear: torque doubles to 2lb-ft but speed halves to 2626 RPM. 1lb-ft at 5252 and 2lb-ft at 2626 both equal one horsepower.

NO POWER IS GAINED. None, nada, zero. I don't know how many times I have to say it. GEARS DON"T MAKE POWER! This is why the Ram would have gained next to nothing with a 6 speed and 4:10 in this test. What is gained in acceleration it is lost in wheel speed as the above math example points out.

BTW, my link works just fine. It opened up on two different computers.

Still think I'm incorrect? All you have to do is show me a chassis dyno that shows more HP with a shorter gear.
