What horse power does a Jabiru 3300 give at 2600 rpm?

FYI
See http://www.matronics.com/photoshare/charles.long(at)gm.com.10.23.2005/ for some good ideas on cooling.
Also, at 2600 rpm per the Jab manual's performance curve graph, available online from Jab USA at http://www.usjabiru.com/), H.P = about 105/ torque about 203 ft-lbs
Hope this helps.

With any engine, name it Jabiru, Rotax, Corvair, water cooled auto conversion (all and any of them). We needs a well designed cowling for the engine and/or the radiator.
Is not easy, is like choosing or carving a propeller, -- If we are going to carve it, we need to start with something that is working in simlar aplications before doing our own, or buy one of the advised brands (Sesenich, Warp, etc to name only two) --
To get a good working cowling, the best route for us homebuilders, I think is to buy a Firewall Forward kit for your airplane (includes the cowling), Then do any little mod needed, in case the temperatures are not the perfect ones, using the advise of REAL flyers in type, from this lists... (Not from me yet, will start my first Jabiru instalation in a 601 XL in a few weeks).
I have already installed 5 Rotax 912 engines, only two was in the numbers for temperatures since the first flight, the other 3 needed a little tweek (sp?) in the cooling system, finally all work perfectly in our area and altitudes... Same happened with the propellers (performance), they needed to find the perfect degrees in each aplications.

Jabiru’s are not any harder than any other engine to cool and probably easier than corvair’s and VW’s. Install them with the same differential pressure between top and bottom cowl and you will get the same cooling performance as a Cont or Lyc. Provide less than required differential pressure and you will have inadequate cooling on any of the engines. Provide adequate pressure drop across the cylinders and any of the aircraft engines will cool well.

But it seems to me the Jab. is a lot more trouble some than most.

[quote] Here's one of those "I haven't done that exactly" replies. There seem to be a whole lot of differences in Jabaru installations concerning "how hot they run". I've found that is the case with most aircooled engines. Some "experimenters" just don't understand the critical nature of the differentual pressure required to cool and air cooled engine. The smallest changes can have large effects on that differential pressure and the resulting cooling of the engine. bob U.
