@Stan Galat, I agree with your assessment of the “new” turbo development. My 997.1 TT has that variable turbine turbo and it is amazing what it can do for torque in the 1st gear off of a standing still. Specially when that “Sport Mode” button is pressed, allowing that over boost. Personally I notice no turbo lag at all. I AM the only lag in shifting to 2nd gear. 

Not young any more!

In my simple mind, I always thought horsepower gives you speed, but torque gives you acceleration.  I wait to be corrected...

In my simple mind, horsepower is how fast you crash into a wall. Torque is how far you push that wall when you do. 

Smiling like he always does and cruising down PCH 1.

Inside the head of @MusbJim.   Yeah, I think I have enough sun screen on to make it to Pismo Beach. ,Yeah, if I bring a cooler of water, I wont have to buy an overpriced soda at the surf shack taco bar.

There's a lot more truth in Jim's graphs than some people realize...

Thank you Ray, Al, Stan.  Yeah I know a little about this and the reference you referred to, Ray, and your explanations, Stan,  are correct. For me, Horsepower rules, but only from the application of it in a vehicle. Torque exists with out RPM. Electric motor torque is measured at stall speed for example. So are Gas Turbine engines. When torque moves, such as with RPM, then work occurs. When work occurs from torque and RPM, Horsepower happens.  But, torque is useless to produce work without some movement. When movement exists Horsepower happens. Marginally, horsepower wins with RPM. Torque numbers are a dynamic function of the moving mass. For example, a Diesel engine has extremely heavy moving parts and usually, the torque is high at low rpm. Horsepower is low.  

Torque can occur without movement but work happens with Horsepower derived from RPM. In Physics terms it would be the "rate".

I venture that a fuel dragster accelerating 1000 ft in 3-4 seconds didn't happen with torque.

Ok, that's my take. If you'd like to beat me up, go for it ! This Quarantine is driving me nuts anyway and I can't do any of the real work around my home until my knees get a little stronger.............Bruce
