What's the difference????

[syang]

I been doing a lot of reading lately on the forum and have was just wonder what was the difference in HP... like how they some may say hp at the wheel and at the crank... what's the difference???


when they do the commercials of have 260 hp in the car is that at the wheel or on the crank???

oh by the way what's does IMO mean??? sorry still can't figure it out...

[syang]

almost forgot how much HP at the wheel does a stock 1mzfe engine has???

HP at the crank is the power output being measure by the rotational force of the crank alone.
HP at the wheels is after it has been delivered thru the drivetrain..that is...gearbox, diff, axles etc. There is always a loss of power from engine to the actual wheels.

IMO = In my opinion.

Stock 1MZ = 180-200HP?? I'm not sure about that..but somewhere there.

In terms of commercials reporting power figures..really depends on the manufacturer, but I would say they'd report it at the crank..makes it sound better than it actually is.

194 HP @ 5500 RPMs. Definitely lose some of that with an automatic...

That same question always puzzled me.

[04sev6camry]

jetspeed- the 03 and newer 1MZs have 210hp

syang- FYI, the average amount of power you lose on an automatic is about 20% from the crank to the wheels
for example, my 3MZ has 225hp to the crank and probably 180 to the wheels + or - a few ponies cause i also have an intake and exhaust

[syang]

thanks alot guys...

[Xevuhtess77]

copmanies tend to report the crank hp numbers.... cause they're higher, to make it sound better

really depends on the car, I've heard rumors that certain companies report certain cars at figures that are dumbed down to lower insurance costs, I believe it was said that this was done with the SRT-4 and so on.
