Another video with our GMC V6 engine.

[James]

The video "The BANNED Rear Gear Ratio GM Quietly Used to Fake Horsepower Numbers". At 6 minutes and 34 seconds it will pan across our engine and at 7 minutes 4 seconds a 702 V12 follow by a diesel V6.

I'm not picking at you James, so don't get me wrong here.
What a stupid video and a load of BS. Gearing doesn't change hp.

[James]

My point was about showing our engines and not about HP.

Understood, thanks for sharing. I apologize for being so harsh.

[James]

No problem.

it's Ai slop.

This is my view on engine horsepower. Gearing does make a difference in the amount of work the engine can do. Horsepower can be rated at the flywheel or at the road wheel/brake after the final drive. As an example farm tractors are rated 2 horsepower ratings. 1 is flywheel/belt/pulley horsepower and the other is brake/wheel horsepower. In the Nebraska Tractor Testing Reviews the engineers give 2 horsepower ratings on the same tractor and the flywheel horsepower is always higher than the brake/wheel power. I believe that the car manufacturers in the 1960's used brake/wheel horsepower ratings to lower the HP to car weight ratio to get their cars in a sub high- performance class for insurance purposes. So does gearing change engine horsepower? Not at all at the flywheel - but power delivered to the wheel is a whole different animal - a farm tractor can pull a load easier in 2nd gear than 5th gear.

Don't get me wrong. I posted this to show our engines being used in a video. I know the gearing doesn't matter for HP. I view gearing as a way of multipling torque.

No problem here my friend. :thumbsup: I enjoyed seeing the GMC V6 in the video. I posted a reply relating my thoughts on horsepower and gearing. When you look into the definition of horsepower it relates to the speed the work gets done vs. torque as the amount of work it can do. We all know our GMC V6 are torque monsters but far from speed demons. Any comments?
