Default Lloyd, look at this!!!

Bwahahahahahaha!!!!



Quoted from Stangnet.com:

---------------------------------------------------------

Exactly

Here is the formula P=T*w P=Power(HP) T=Torque(ft*lbs) w=rotational speed(RPMs) The motor power output remains the same so as rotational speed decreases torque must increase.

If power is conserved then (T*w)(in)=(T*w)(out)

I will use the stock Mustang at peak torque in forth gear with 3.08 gears and 3.73 gears.

300*(3200)=T*3200(1)(1/3.08)

Total torque at wheels=924ft*lbs note: That is total torque measured by a dyno to determine transferred torque (RWTQ).

300*(3200)=T*3200(1)(1/3.73)

Total torque at wheels=1119ft*lbs

So yeah you will see more torque with a lower gear.

P.S. Sorry to open this back up, but I had too <img border="0" src= smileys/smiley4.gif>

Right. Just not HP they are two different measurements.

BWAHAHAHAHAHAHA LOL

But HP=TQ*RPM/5252, so HP is directly related to TQ. As (RW)TQ goes up, so does (RW)HP.



Sorry, I just like arguing with moderators.<img border="0" src= smileys/smiley2.gif>

Without changing flywheel horsepower? I dont think so. Ive said it once and I'll say it again. Gears dont add horsepower they just bring you into the powerband quicker. THINK ABOUT IT

I have been, and I'm sorry to say, I still think that I'm right. I get your point about bringing it up in the RPM's quicker, and I understand the concept of 3.73:1 ratio (driveshaft spins 3.73 times for every once the wheels turn, motor spins more according to tranny gear ratios), but RWTQ/RWHP differ from FWTQ/FWHP because of several factors, and I think one of them is the rear diff gear ratio. RWTQ/RWHP is how much force the wheels are putting to the ground, and if you're gonna go faster, you need more force to the ground, therefore when you're going faster because of gears, MY belief is that your putting more power to the ground, i.e. power=TQ/HP.



Seriously though, this debate could last forever. I guess it's all in how you look at it. I have yet to see any dyno results proving this, though I hven't reall looked.

No problem. It is kinda childish to argue over it, who cares as long as it makes you go faster!! I'm sorry for my part in keeping this going.
