Lift, low wing vs high wing single engine

So let's say you have a single engine, high performance plane. There's some amount of lift provided to the wings via the propwash. Negligible or not there's some coefficient there.

Question is: Would the lift increase on a low wing plane, or a high wing plane.
 
It totally depends on the plane and where the props are relative to the wings.

I would throw a WAG out there that, in singles, the low wings probably get an advantage on that just because the wing roots are directly in the prop wash, but again, that's completely a WAG. It may be that the Cherokees and Bonanzas have something that causes the prop wash to not be a meaningful effect, or maybe the Cessnas get the prop wash pulled up the windshield and it gives the same lift you would have gotten from a low wing.

I will say it's going to depend heavily on the particular airplane.

Totally dependent on where the propwash is with respect to the wings. If the engines are wing-mounted, then the accelerated slipstream coming off those engines is going to significantly add to the lift of the wings when power is increased.
 
Now, what if it takes off on a treadmill, while retracting the flaps during rotation AND canceling IFR simultaneously?

JC MYTHBUSTERS, HOOOO!

Re-read my post, single engine not multi.
