Maybe not "afforable" but definitely more aforadable-er

What do diesels do on the brake for spooling? Lots of fuel and retard timing? Or do you oscillate the timing?
On gas applications I use as much timing as possible to hit the 2 step on the transbrake as fast as possible, then slowly pull timing as boost comes on. It's a bit different though we pull spark but not fuel on the limiter. It lights in the exhaust manifold.

Yes, seems like even diesel guys are finally starting to understand how turbochargers work.

I mean after all, even the most advanced gas motors are still behind the curve compared to most diesels.

Rpm makes power, diesels cant make high rpm so they dont make power. Gassers are running 100 psi boost single stage these days, at 10000+ rpm. Formula 1 engines did 80 psi already in the 80s.

Actually TQ makes power, HP is just a calculation. But who's counting?

My Snap On guy said my engines are RPM limited because I use a Torque wrench to assemble them and need to upgrade to one of those fancy Horsepower wrenches.

You need horsepower to move your vehicle.

I thought torque was the force to move an object?

I like the saying, horsepower is how fast you can hit the wall, but torque is how far you move the wall after you hit it..

How about.... horsepower is the ability to do work, but torque is how much work you can actually do....Or BIG TORQUE MATTERS.....

NOPE! I need tires and wheels to move my vehicle! Right now it's missing both and it's stuck on jack stands

That and "horsepower sells cars, torque wins races" make me laugh. Whenever it's uttered I immediately know that I'm dealing with someone that has no clue what they're talking about.
Ever wonder why the ET calculators use HP and not TORQUE?

Not exactly.
Horsepower is a function of torque and rpm. Both are equally important. Double either and HP doubles. Double both and HP quadruples.
Shift points match the horsepower curve, not the torque curve, ever wonder why?

That's the most idiotic explanation I've read in a while.

And the HP curve is calculated from the TQ curve. Can't just spin it to 10k and expect to make awesome HP, the engine needs to produce some tq up there (obviously less than you need at 5k like you are getting at). Being that HP is a function of said tq, the shift points will match BOTH
