c-90 cam in 0-200 engine

Post by JJJones »

I know this is an old subject. I need a new engine in my champ and chose an 0-200 to build for it. does the c-90 cam actually move the o-200 power to the 2500 rpm range ? Does anybody know for sure ? Is it worth the hassle ? thanks

I don't think it would be worth the hassle. You could make up any losses by lightening up the airframe.
There are three cams available for the C90, p/n 530788 35 deg overlap, I believe, and the 531076 & 531146, 24 deg overlap. The later require a slightly different hydraulic unit for a 3 to 6 second bleed down rate. I'm not sure if the FAA will allow any mismatching of parts without TCM approval.

For your info: I have the 0200 in my L16A (basically a military Champ) with the Buzz Wagner STC. I think it performs pretty well considering it wound up weighing about 950# when I finished which doesn't leave you a lot of room when the gross is 1300#. Technically I could go to 1350# because I have the no bounce gear but decided to keep it at 1300# for light sport purposes. Just doing the STC seems to add a lot of weight as you need additional fuel so the tanks added around 18#, metal prop, Cessna or Halon-Wilson exhaust, etc. I also opted for a battery starting system, Sky-Tec starter, new .032 ribs, heavier leading edge, Lexan greenhouse..you get the idea it all adds up. I was hoping for around #900 but no luck so if you can find some way to lighten it up you'll obviously increase the useful load.

Now I'm a pretty light guy at 160# soaking wet and I mostly fly alone so the extra weight is not a problem. Put someone else in and I look at the amount of fuel I'm carrying.

Anyway, I though the 0200 was a good match and the installation wasn't that bad either. I have a information sheet I wrote up after I competed the conversion if you decided to go that route.

Do you have the big tail?
Keep the pointed end forward--
The dirty side down.....
And the blue skies on top....

Grumps, yep....also a big tail although the Wagner STC 'recommends but does not require" the big tail for "spin recovery" (their words). Overall I find it a pretty good conversion although it leans toward 'nose heavy' CG even with a 24 battery behind the rear seat. At least parts are still available for the 0200 while they seems to drying up for other engine like the C85 cams, A65 cylinders, etc.
