Dune buggies have a cooling problem with type 3 engines, in that they generally suck in hot air at the back of the engine and expect that to "cool" things. Unless you make some provision to actually provide unheated air, souping up such and engine will just make things worse. I was considering the following modifications. > a..

Larger pistons Can be done, and this will still fit in the shrouding. > I am also planning to do the full flow filter. A very good move, but requires a complete rebuild on a type 3 engine. > Is the type 3 engine worth more than a type 1 if I leave it alone? No, probably less. There's not much market for type 3 engines. > Would I be better off to sell my engine and get a type 1 to doctor up? It is generally easier to get cool air ducted into the intake of a beetle engine in a buggy. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
