Rob - I am totally unfamiliar with the set up you have.Never heard of K&N
but I have never understood why we need to filter the air once airborne.
My plan was to go with the Silver Hawk injector, mostly because that is what
everyone offered if FI. Reason for going FI was here in the UK carb ice is
frequent and I presume the injected engine is smoother and more frugal on
fuel. However the things stacking up the other way are:
- I really prefer the look of the O-320 cowl
- the air inlet is presumably matched to the engine
- VANS can supply the brackets for the carb but not FI and the O-320 FAB
will fit
- there are not so many aircraft to copy how things are done near me. I have
built a carb -9A before and feel more confident.
- there was also an interesting old post at Vans Airforce "Carb vs Fuel
Injection" by Stein Bruch which go me thinking that perhaps the money is
better in my pocket.
Feel free to tell me I am making a mistake if you feel strongly.
If I go back to a carb I guess I have to understand if I want a Marvel or
someting else. Is there any other carb I should consider? If so what does it
offer?
Cheers, Steve.
