How about RAM air? Is that even worth considering? Ram air is not effective at low speeds. "Andre" wrote in message ... I operate off an airfield with a ground elevation of 5327 feet ASL. Obviously my engine (VW 1835cc with Zenith Carb) feels the altitude somewhat. Just somewhat?? :-)) I am thinking.... Would Turbo charging help? Probably turbonormalizing...It's not as hard on the engine and would give you take off power at 5300. With a carb it get a bit complicated as the carb needs to be in a pressure box. What about an electric blower to increase manifold pressure maybe? Not familiar with them. Or how about a NOS system? NOS needs a rather healthy mixture to begin with (As I recall it helps with cooling)...I'm not sure about the higher altitude effects.

NOS needs a rather healthy mixture to begin with (As I recall it helps
with cooling)... NOS adds a bunch of heat to the engine, so no, it doesn't help with cooling. Basically, it's a safer way to add oxygen to the incoming air than injecting oxygen directly... so since the incoming air is now much more oxygen rich, you need a bunch more fuel, or your mixture will go very lean. In that sense, it's an alternative to turbocharging... but the NOS bottle will last a minute or so, OK for one takeoff... then what? :-) Paul, turbo Cardinal mode |

Ummmm..no, that;'s not what I said. I said it requires a rather healthy mixture which helps with the cooling (need created by the NOS) Roger Halstead (K8RI EN73 & ARRL Life Member) www.rogerhalstead.com N833R World's oldest Debonair?

complicated as the carb needs to be in a pressure box. No pressure box required for Marvel Schebler / Precision Airmotive carbs... just installation of a third throttle shaft seal (did it on my Cardinal when I turbonormalized it). Paul |
