Im seeing about 14psi and it falls off 2psi in higher rpm's. I have some slip though, need to go down about 1/2 inch on the belt 74.5 with 2.8 and 100mm idler, gettin some dust in the spokes.

I am seeing a steady 13lbs with little to no drop off...the needle just pegs 13 psi. is this because I have the TB and plenum? I can't see my 2.93 putting down 1 less psi than a 2.80....

broke7 Wednesday we need to go on a run, you need to film my gauge during a 3rd gear pull, I am very curious now

On a 4th gear pull on the dyno you will see drop off.
In 4th under load you will actually see more boost and also more drop off.

thats cool.

I was seein 14psi today maybe 13.

The charger has a real cool whine/whistle now at cruising speeds and part throttle with the tighter belt. I think my slip is gone finally.
