anyone GUT their cat?

[Gen1GT]

It has already been proven that the first cat is not needed and the second stock cat provides enough backpressure to keep good torque on a N/A FS

THAT's how it all came from the gutted cat question.

High RPM power, is the same as high RPM torque, and low RPM power is the same thing as low RPM torque."

I stand by that. If you're making a lot of low RPM torque, you're also making a lot of low RPM power. It's the same thing. If I'm making a lot of high RPM torque, it means I'm also making a lot of high RPM power. It's the same thing. Because HP is DIRECTLY related to how much torque your engine produces at any given RPM.

=) ok, its the same thing. so, if i have torque, then that means that i must have power, correct? so, this statement directly contradicts the one you just made. "HP is a rating of how much work is being done. You can have torque and be doing NO work." so if its the same, how can you have torque and not be doing any work? simply put, you cant. in order to get torque, a force must be applied. and if you have a force, then obviously you have to be doing work applying that force. hp is simply how much work can be done(ft/lbs PER MINUTE). torque is the amount of pressure(ft/lbs) created by applying that force around an axis.

OK, I see your point. You don't have to be doing any work to have torque, no. But it's IMPOSSIBLE for our engine to make torque at Zero RPM, so as long as our engine is running, it's making torque AND horsepower. When I say low RPM torque, it automatically implies that the engine is rotating, and making it's specific torque at a specific rate. This RATE is hp. At idle, a car may be only making 70-80lb/ft, but that 70-80lb/ft at 750RPM makes maybe 10hp.

So when someone says, "my car has lots of low RPM torque." It also has low-RPM power. That's how they're directly related. 100lb/ft at 2000RPM makes 38hp. There are NO variables to that. 100lb/ft at 2000RPMs makes 38hp on every engine, at every load, in every condition. Now, if that very same car makes 120lb/ft at that very same 2000RPM, then it now makes 46hp. THAT is the DIRECT relationship between hp and torque. However much torque you make(as long as the engine is running) DIRECTLY affects how much power you're making at any given RPM.

Note that, that very same 100lb/ft, but at a higher 7000rpm makes 133hp.

=) ok, im happy now. directly related, yes, but not the same.
