Psi screw D rotor vrs C rotor ???

On a 481x, Is there a notable performance gain if I were to sell off my D and went with the C ? 120% over, I'll use the same hat,pulleys,etc. I know the C pumps more air, But, hase anyone ever switched and what is it worth in 1/8 mile E.T.? Is it true that the C will make 10 psi more boost ? I'm trying to decide if it's worth selling my D and stepping up to the C. Outlaw 10.5 car, 3170lbs. Thanks, Please private message me if you would like not to air out your findings on the forum. Thanks again!
