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 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.

I clicked your link, nothing on the page was a turbo diesel.. what type of engines is this thread about??? Turbo Diesel's don't dyno in lower gears for a reason. We are not talking about NA gas motors that have power come on much quicker.

Additionally, 3rd gear of how many? 3 of 4 is a VERY different game than 3 of 6. Use ratio's, not gears.

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

Duh.. it increases wheel torque.. as stated, and has been what the discussion is all about. I mistyped power AND then corrected myself.. scroll up and re-read.

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.

Again, DUH... But which one does more work??? HP is the rate at which work is done, torque is the amount of work. The 2:1 gearing does 2x the work in the same time. How does that not make a vehicle accelerate faster?

It is a simple example, look at your own answer. 2x the torque for the same hp.

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

It didn't open on my ipad or computer??? Not sure on that one.

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

As I already stated.. DO NOT confuse hp for torque.. get off the HP kick, we are talking torque. Both are important when talking towing.
