The numbers are listed in the Haynes manual. The only thing I dont know 
is that the numbers are listed at a given rpm, but since the T1 has 
different sized pulleys, I dont know if the T1 is listed at crank rpms 
or generator rpms. I presume it is crank rpms.

Anyway, 
T1 65-up 1300 is listed at 550 liters per second at 4000 rpm
T1 65-up 1500 is listed at 575 liters per second at 4000 rpm
T3 is listed at 580 liters per second at 3800 rpm.

It seems that the T3 pushes a bit more air than these two, but sinc I 
dont have specs for the T1 1600 Doghouse style cooling system, it's a 
bit hard to say. And the Doghouse system is what most performance people 
uses anyways. Anyone have a 1302/1303 Superbeetle Haynes manual look it up?
