Some of you may have misunderstood my intent.
I calculated the hp per the usual rules, and inserted the numbers to be meaningful, in terms of understanding acceleration, an understanding of which is harder from the torque numbers.
As soon as the car is moving, torque turns to horsepower.
The result are the same either way you send it.
For example;
171 hp at 3000rpm is 300ftlbs. and 300 x 9.14 = 2742 ftlbs, into the axles, and
149hp at 2600 is still 300ftlbs; and 300 x 10.71= 3213 ftlbs into the axles, an increase of 17.2% with a stall reduction of 400; and
144hp at 2800 is 270 ftlbs...... and 270 x 11.23= 3032 ftlbs into the axles, an increase of 10.6% over base 2742, with a stall reduction of 200 from base .
Looking at the Torque numbers belies the horsepower delivered, which is all over thev place from 144 to 171, yet about the same into the axles, namely 1592+/- about 1.6% which is the point I was striving to deliver. Thus you can see that, for a streeter, that rarely exceeds say 65mph, it does not need a lot of power to get going if it has the range of gearage dialed in. And the A500 has a lotta of range; going from
2.74 to 1.00 to .69od, is a gross range of .69/2.74= 3.97 (Compared to 1.0/2.45=2.45 for the A904) which is a lot of range, almost more than you need. and LU being worth another 3% or so;
so because of all that, the engine does not need a lot of stall. Proving that, with numbers, is the point I was trying to make.
My hope is that this makes things easier to understand.
There is no trick math here;
(Torque x RPM)/5250 = horsepower
(HP x 5250)/ rpm = torque
It's just math.
