ACCUSIM CESSNA T182T inconsistency

I would like to report that the ACCUSIM CESSNA T182T is inconsistent with the real POH.

For instance the green range for the manifold presure values in real POH is 15-28 but in the accusim Cessna T182T is 15-25.
When at presure altitude 2000 feet, full gross weight and with MP = 20 and RPM = 2200 the TAS is about 137 knots when according to the real POH is should be around 114 knots.

Why is that ?

Operating system WIN7 - 64bit
platform FSX:SE

The :a2a: Cessna 182 is not a turbocharged 182, so that could explain the difference on the manifold pressure gauge. I don’t have any explanation on the speed difference

:a2a: Feel free to move this to the correct forum. There’s a slight inconsistency in posting a 182 matter in the 172 forum :wink:

Giorgk,

You are looking at numbers for a T182T, which is a turbocharged version of the 182T (the one we accusimmed). At low altitude a turbocharged engine will produce less horsepower at the same altitude and manifold pressure than a normally aspirated one. And the turbocharged version allows for a higher manifold pressure as well.

Nick just informed me of some inconsistencies aside from this that I'll be testing today.

Sorry dear Scott,
i thought it was the T182T version. I apologize for that.
