Low speed torque and driveability ?
Ive dipped in an out through out of the thread i aint read it all sorry...
torque, measurable physical unit
diveability emotive description of function of car on the street
350 ftlb or torque at 300 rpm
280 at at readline of 700 rpm
Ok that's a1930s 20 litre diesel tug-boat motor
drivability with a 3 speed box would be quite poor. unless its a road roller. or a tractor for moving the space shuttle to the launch pad.
You'd have no problem setting off in any gear but its gonna take a very long time to get there and and your MPG will be awful.
drivability with a 16 or 20 speed box might be quite good if you could put up with changing gear.
torque curve and the correct gearing for the job in hand. The aim? getting to walmart at a brisk pace... or getting to the end of the track as fast as possible
OK now we can say something about drivability... and it would be
My gearing is perfectly matched to the characteristics of my engine in an RPM range that seems reasonable for the application
if the car is designed to drag race you can't be complaining about drivaility on the street
street driving was not the application
If you street drive and your performance improvements all come out of the drag racing box
maybe that wasn't a performance improvement, it cost the same as a performance improvement, that someone might do to a drag car, but didn't improve performance for your application...
poor drivability
