$50 Super Charger (the strange red button explained)

Drew, you are right, I have a patent on a v-blade brush cutter and when I began building it I was told by a man who should know "it will never work, a four wheeler isn't powerful enough to push it and cut brush". He changed his mind when he watched me cut a 5" pine tree with it hooked to a 350 Rancher! Things always work better for me when kept to their simplest form. When I started playing with this idea my thinking was along the lines of even if the fan only helps to move air through the carb more efficiently there should be some gain. The main reason for building it was curiosity to see if it would do anything at all, kind of like the hydrogen "run your car on water" thing, it was a fun project. BTW the water thing is another cool idea, along with steam injection...

I've thought about mounting a gas powered leaf blower on the back of a machine and route a hose to the front of my Argo, at the firewall it will Y off, one tube will go to the fresh air intake on the motor, the other pipe will go to the brakes and will cool them and help the warm air flow out the top of the hood better. This should help the Briggs 23 considerably, since they were designed to run very lean and it has a tendency to evaporate the fuel in the carb when its being pushed.

hi
The bilge fan or similar will only be promoting additional fuel metering from carburetor and promote better cylinder filling eg normal engine operates around 80-85 %VE. Adding a fan may well take this a little higher 90-95% A turbo and super charger operate at 90-120% VE .
The moral of the story even if there is a gain some where, all be it minor ,the most likely miniumn is better throttle response from improved carby metering of fuel .

The big question is will this only work on an engine that is not metering fuel properly to start with eg worn honing marks in cylinder [causes lack of vacumn therefor less sucking on carb ,less fuel]
The majority of mower carburettors are not suitable for constantly repeated, accelerating operation eg no accelerator pump
Mower engines only have to travel across the mid range when u first start up or at the end of day when powering down
Also Compared to 2 stroke a 4 stroke is a lot slower reving and typically fitted to a heavier and or higher loaded machine

The main point is to fit a carb that is suitable for application eg with an accel pump
This may well give the same results as the blower bilge fan ??
Remember by using the bilge fan that a lean or rich condition may be occurring neither is good for an engine in the long term .

I ran across a 26.4 hp cat turbo diesel some time back, it weighed comparable to some of the big block mower engines and was listed for a tad under $2300 and... it's a CAT

Sort of on topic, I saw something in a car magazine a few months back where they took a couple of leaf blowers and used them to turbo charge a car. I don't recall all the details, but it was not impressive.
