engine dyno

Recommended Posts

Just thought I would post a pic of my latest creation...a homemade small engine dyno built real cheap. Its actually somewhat accurate too. Not really interested in 100% calibration but it will tell me if what I do makes an engine better or worse. And let me know where my peak torque is. Also works good for breaking/breaking in new engines! Haha

Its a really simple setup that anyone could build. Basically a brake mounted on a shaft with a torque arm attached to it that has a scale on the end. Once I get all the bugs worked out of everything I do plan on having a buddy of mine thats an electronics guru help make everything electronic. Then hopefully I can hook to the computer and graph data. So far I only have about 200 bucks in the whole setup. I figure with electronics that could easily quadruple though. Once I get some action videos I will post em for all to see.

So the other half has been out of town for three weeks now so I decided to play with the dyno a bit. Built a bone stock 12 hp and ran it and Im very close to actual dyno sheets printed by kohler. Since I had some extra time I played a bit with simple changes. First being a straight pipe vs a muffler. On a bone stocker it didnt seem to change a thing other than making some noise! But you gotta love a Kohler with a straight pipe. Then I built an E85 carb to see what kinda gains I could get from that...3 ft/lbs peak torque gain and 1.8 hp peak hp gain. Just from bolting on a carb! Made me happy enough. Next is a three angle valve job and maybe a cam. If I can get a buddy of mine to video I will try to get some posted. Otherwise I will just share what I find. Either way its alot of fun and could get very interesting.
