Rep Power: 0 Horsepower, and Automatic vs Manual transimission's...
Just wondering something. Is there usually more power loss through an automatic transimission vs a manual, or is it the same? If it's not, why is that?

Rep Power: 314 well automatics use a hydromatic torque converter and manuals use an actual plate that physically transferrs the rotation from the crank shaft to the gearbox so there probablly is more hp loss

Oooh ok, but it's not THAT much more loss is it?
Does anyone know how much hp the Si (EX in the US) puts out at the wheels?

Rep Power: 0 Your joking right spider??? you think a automatic tranny shifts faster than a manual tranny???
I'll agree with you, the auto shifts faster than some people but there are some people that are able to make a shift quicker with a 5spd than with a auto. It may not be as smooth as a auto but it is faster. Also if you think about it the transitition of the shifts from gear to gear in a automatic is almost always slower than the transitition of shifting gears in a 5spd.

Rep Power: 0 Ok guys calm down here, I didn't intend to start a flame fest. So if the power loss through the transmission in a manual is about 15%, an automatic would be about maybe 20%? Or not that much?
Anyway, putting aside that a manual is faster or whatever, it doesn't mean an automatic isn't fun.

Rep Power: 0 Yes, I modded my previous car's automatic transmission. Shifting between gears was nearly instant. At WOT, 2nd gear engagement was enough to give whiplash to the driver. Damn I miss that car.

Rep Power: 0 You might want to check out the HX's CVT. Automatic functionality without the loss caused by the torque converter in a normal auto. A couple CVTs here have beat 5-speed EXs.

Rep Power: 0 Now your talking different things, shift kits are not standard or stock options on most vehicles.....The way the person asking the question was talking, he wanted to know stock for stock. Yes definetely aftermarket transmissions, and aftermarket transmission add-ons can make a automatic faster than a manual, that is no argument, but stock for stock not all autos are faster than manuals.
And for the record I used to work for a speed shop called Speed Inc. based out of Schaumburg, IL located right off the Elgin O'Hare expressway, so I do know about fast cars.

Rep Power: 0 Must be nice. For some reason Honda chose not to sell the CVT's here in Canada
Can someone tell me what they sound like? Because I mean I wonder, seeing as it's only like one gear, so does it rev up like a normal car, or is it just a constant sound? I have no clue what I'm talking about as you can see

Rep Power: 0 Auto and sticks both have thier place. Auto's are used in drag racing because they shift quicker. Manuals are used in road courses because you have more control over how much power is being delivered to the wheels. I myself drive a 5speed because it's just more fun. Untill I have to sit in traffick..then I wish I had an auto. I test drove the mazda6 with the sport auto shifter..that seemed like a decent compromise between the two. But on a stock vehicle..a 5 speed will usually (and I strees usually menaing not always) take an automatic with the same powerplant.
