Power mods for the I-5

HP is not the limiting factor, unless you are talking about heat rejection due to internal friction, or a design limit for maximum internal rotating speed.

Most engines do not produce their peak torque at maximum RPM as you are implying here.

Check the manufacturers specifications for drivetrain components. They do not list horsepower. They do list torque.

Come on...... do you even know what HP is? HP IS a measure of torque.

No, it is not. It is a measure of power.

I bet you are one of these uninformed people who thinks the faster car always has an engine which produces more torque.

brain trust going at it! I like it!

Mostly useless info, still no proof of significant power increase to the I5 without s/c or turbos.

Where did you hear that? From a horse?

Ok, sport. Here's a little lesson for ya'

Torque is tangential force TIMES the distance from the fulcrum or a measure of force at a single moment in time. HorsePower can be defined as work (force over distance) per unit time.

Applying 1 lb of force 1 ft from the fulcrum for a complete revolution will lead to;
W = F*2*Pi*r = 1 lb * 2*Pi * 1 ft = 2*Pi lb-ft = 6.283 lb-ft

If it takes one minute to complete this revolution, then the power is;
P = W / time = 6.283 lb-ft/min
1 HP is defined as 550 lb-ft/s or 33,000 lb-ft/min

Therefore, applying 1 lb-ft of torque in one minute (1 rpm) = [6.283 lb-ft/min] / [33,000 lb-ft/min] = 1/5252 of 1 hp.
From this you can then calculate the number of hp from any given torque and rpm:
HP = Torque * RPM/5252 or
HP = Torque measured over time and distance.

Therefore, HP is a measurement of Torque over a given time and given distance.

First off, I don't need your lesson.

Second, that's not what you said. You said it was a "measure of torque", not a "measure of torque over time". You've just proven my point that horsepower is a measure of power, not a torque measurement. If horsepower was purely a measure of torque, then how is it that 1 horsepower = 745 watts? Just because torque is one variable in the equation of horsepower, doesn't mean it's a measure of torque. That's like saying wattage is a measure of volts.

Ok,

do you attempt to think with that thing you call a brain or does it just occupy space. Go the fck back up and look at my posts. My first post in this thread where you have spat your ignorance contained this little gem "Since HP is the measure of torque over time, HP is just as limiting a factor as torque. You can't have HP without torque."

To which you disagreed.

Care to try some more?

You absolutely do not know what you are talking about. Show me one, just one specification sheet from an OEM manufacturer of transmissions or axles which has a limit on horsepower.

The problem with your brain is it can't distiguish between "power" and "force". Pity.

The other problem with your brain is it just doesn't have any class. You come on here trying to insult me and everyone else, while doing your little chest thumping routine. We're not impressed.
