Hey all/robert,

I switched from a T-66 S-trim .81 AR (OC) to the identical turbo but Q-trim .96 AR... as an experiment in lag/flow.

Interestingly, I noticed that backpressure (pre-turbo) seemed to go up as we lost 1psi of boost telling me that there is more pressure on the bottom of the WG. Does this sound right?

I realize that the S-trim is a better flowing wheel than the Q, but is it so much better that a .81 to .96 actually made BP go up? None of these turbines are F1 style wheels btw.

Thanks for the help.

Yes actually the S-Trim flows THAt much better,.
