Just to start off I did search this topic, but was unable to find much for the Baron.

I would like to add a little speed to my slow Baron 58.  I found the 'TC' downloads, but none of them have the G1000 cockpits.  I remember some discussions about people altering the Aircraft.cfg file, but I am reluctant to do so because I dont properly know how and I dont want to screw up a good thing.  Currently everything redlined I am around 145KIAS (7500'ASL), wouldn't mind 200+KIAS.

Any ideas?

Thanks.

It sounds like you aren't leaning properly.. 

I just took the default Baron up to 7,500msl and got ~170KIAS. wich is ~190KTAS ..  which is very close to realistic, maybe a tad slow...

A few years ago.. I did a turbo-mod for the Baron.. I can't remember if it was for FS2002, or FS2004. I do know, that if I had known then, what I know now, I'd have never uploaded that mod..  there are just too many compromises re: takeoff/climb performance vs cruising speed.. I mean, you can make a C172 supersonic, if all you want is speed..LOL

If you're bound and determined to get "TC" performance out of the default Baron.. a relatively simple cfg edit will simulate bolting on some turbo-chargers; that will sustain sea-level manifold pressure up to 18,000ft..  Make a backup  of the aircraft.cfg file, for obvious reasons.

This is the [piston_engine] paragraph, from the Baron's aircraft.cfg file ...

Now, of course, performance realism gets skewed a bit.. so it's up to you if you want that compromise (or spend hours tweaking things like; thrust, induced_drag, parasitic_drag, wing_efficiency)... and you still have to mange the mixture as altitude increases (or when taking off from a high-altitude airport).. 

To me, it's a solution to a problem that doesn't exist; as the default Baron is a very realistic representation (and you'll get quite a performance boost, as you learn to manage the mixture). If you want high-altitude, turbo performance out of a light, piston twin..  get a C340, or a Beech Duke
