Looking to make a dyno with no clue at all ?

Anyone got any links to making a dyno for 1/5 2wd and 4wd. I have no idea where to start ?

You can buy framing extrusions from grainger.

I made the prototype on 3/4" plywood ! I have quite a bit of mass in the brake disk and axle , it needs some weight to be stable , beside I ran my motor on it and a small light frame is not what you want for these motors IMO.

However the frame can be secured. Aluminum frameing would be much safer then plywood though I would suspect these cars aren't putting enough power to brake wood either.

This is a Brake DYNO not a intertia dyno , it requires larger components for these motors. I also want to be able to run 10+ HP

If you don't sort the fuel supply to that engine you won't be doing many more test runs, it's starving ?

I've plug checked it a bunch of times , I'll fatten it up once I get the carb rebuilt , broke the damn fuel inlet pipe off the carb. BTW a properly tuned 2 stroke does not always smoke , I ran carts at max tuning for 5 yrs , when tuned to the max power they do not hardly smoke BUT you have to be careful !!!!

we used exhaust gas temp sensors to max out tuning.

It wasn't the lack of smoke why I commented, it was the engine note??

Oj It was just getting on the pipe never really revved it up , Plus I re-tuned it sense then ,

BUT I will keep a close eye on it THANKS !
