Do you have a torque curve for a p-ported turbo 13b somewhere?
Thanks, Mike

No. Sorry. A lot depends on the turbo chosen.

Also how the dyno run was made. If you slam the throttle
open you will get one torque curve and if you slowly
advance the throttle you will get another.
This is because of turbo charger rotational inertia.

Is this a car or airplane? Airplanes run at
steady RPM so much of the car turbo charger
stuff is not applicable because car turbo charger
systems are designed to accelerate the turbo charger
RPM (boost) rapidly.

You can get a rough torque curve for an aircraft
configuration  by assuming the HP curve verses RPM
is a straight line from zero to max HP.

For example: Say the max HP is 400 HP at 8000 RPM.
At 4000 RPM it will be 200 HP.

HP = Torque X RPM / 5250 so torque at 4000 RPM
is HP x 5250 / RPM or 200 x 5250 / 4000 or 262 foot pounds.

Here is a dyno run for a 500 HP turbo charged
3rd gen side port engine. The torque jumps up fast
because the boost jumps up fast to 18 psi and is then
limited by the waste gate opening.
