Another chainsaw dyno...

[7-pin]

Rings yet to seat?

Saw had maybe 20 tanks through it before porting. (Unless I am missing something fundamental about porting that alters ring seat?)

Oops…I had assumed rebuild, hence, new rings.

That was my thought but I’m sure the porters can elaborate on this…

Well been holding out.

Finally got tired of cutting wood.

Wanted to share my new tool with the class.

First few runs after getting everything all calibrated.

This has a built in weather station, to keep track of temp/humidity.

Those are the sae corrected numbers. Very close to the 660 book specs.

Last week's project making the "bench" and jackshaft.

This is a 30hp rated waterbrake, 17k rpm

Have A 2:1 reduction. Helps smooth out the runs with low tq saws.

Adjustable power head rest with a thick rubber cushion.

Designed it to work with Any power head I could think of. Even raise up enough for belly pipes.

If it can run a std 3/8×7 rim I can run it on the dyno.

Thoughts?

Thanks for the work . we all benefit !
