Hi! I've been doing a lot of info digging on twin screws (Autorotor/Kenne Bell, Sprintex, Lysholm, Whipple, etc), but I can't seem to find any flow maps for the whipple units. Lysholm has some great flow maps for their 1600 and 2300 units, but Whipple claims much higher adiabatic efficiencies.

I'd really like to see some maps for the W100 and W140 units. I've got a desire to put a twin screw on an old 200" Ford Falcon motor, so it's not just a case of look and see what other's have done.

Can anyone help? Thanks!

John
