gear ratios and torque

Now let's talk about TM (Torque Multiplication)
For a streeter (all I know)
Lets say you had those 3.23s and 145#@30mph which being 2950rpm.
And lets say you had 27" tires. So then ftpounds to the road would be
145x2.45x3.23x24/27=1020# on the tarmac, multiplied by whatever the TC is doing.
And with the 3.55s? At 30mph we had 165# @3250 so;
165x2.45x3.55x24/27=1276# to the road... and
1276/1020= plus25% !
So if you had a 273 cuber this would be a really big deal. With a smogger-teen still a big deal. But by the time you get to a hi-torque 360, it is still spinning the tires @30mph so it means almost nothing.
But when you get into second gear and the spinning stops; that 25% is now adding up to be very important, to a streeter.
But two things are happening in second;
Firstly the torque curve is flattening out so your 25% advantage is constantly decreasing; take another look at that curve; from 4400 to 5100 the torque curve is pretty flat there, so when you are powering thru there, your advantage would drop to the 10% gear advantage. So for a streeter this could still be pretty important, but for a drag-racer not so much. And then on the downside the torque advantage is again increasing.
So, bottomline is anytime you are on the steeply rising/falling parts of the torque curve, the 3.55s are doubly helping you, whereas on the flat part, only the 10% gear advantage makes it thru.
And finally, if you can spin your tires to the speed limit with 2.76s, well, then this conversation is meaningless,lol.

Ok but let's not lose sight of the big picture.
In a streeter, 60mph is 5900 with 3.23s in first gear. And 6500 with 3.55s; if you have to shift, the 3.23s could get to the stripe first. It kindof depends on the combo.
