200H

M -- 206mm Billet Rotor -- Marine or offshore blower originally manufactured and set up for gas boat racing

C -- driven rotor lobe thickness .483" - .485" - 476 cu.in. per/rev or 7.616 liters per/rev ---> 210mm rotors
 --> "D" at 125% =approximately a "C" at 104% /  2.25/2.04 = 1.102 - 1 = 10.2%

D -- driven rotor lobe thickness .594" - .596" - 422 cu.in.per/rev or 6.752 liters per/rev ---> 206mm rotors
 --> Top Alcohol Dragster =  422 cu.in. x 2.15 or 115% = 907.3 (NHRA-1996)
 --> Top Alcohol FC =  422 cu.in. x 2.25 or 125% = 949.6 (NHRA-1996)

Whipple 601 cu.in x 1.60 or 60% = 961.6 (1.2% advantage in swept volume however just as before based on the math 9.8 liters or 612.5 x 1.60 = 980 (3.2% advantage in swept volume)

Weld Replace Inlet


Note : long Double Bearing Shafts


Quick Removable inspection - Lubing top cover
Tight blowers Must be lubed every time it is started

and of course you can get a billet version.
