I am going to be putting my d19 Diesel on the dyno this week end at the local tractor show. I am curious on how much boost the turbo is putting out, I have looked in the i&t and factory AC service manual and it doesn't list any spec's for boost. Does any know how much boost the factory TRW turbo is supposed to be putting out?

Thanks Matt

A stock tractor, I would guess around 8lbs. Turbocharging was in its infancy back when that tractor was built...they dont boost as much as people think

I read in one of the manuals its should be around 3 - 5 psi, like Don said turboing was new then.

general rule of thumb is 10hp per psi, so 66hp=6-7 psi.
