Pulley swapped mower woes

[Braeden P]

I got a 1999 lawn general mower (MTD) since it has gears and not a hydro, removed the 9” rear pulley and put in a 2” pulley. Top speed was 36 MPH

Yesterday I borrowed a turbo from my friend from a 1.5L, removed the governor and put it on, went to 40 MPH then at the end of the first run, starting the second there was a loud bang and a puff of smoke, snapped the axle the transmission in half from way too much power, there was no mowing deck and my 110 lb brother was driving it. We had a hose on the turbo going into the intake when it blew up and we were getting a lot of air flowing.

I think maybe you exceeded the original design specs .....

Let me look out at the bone yard at the farm. May have another transmission. It will take a couple of weeks to dry out enough to get to.

Im looking at get a cub cadet just because they have a cast iron transmission and a real clutch, mine wouldn’t have broke if it had a clutch since you had to grind it till you find it.

Here’s the cut down video of it with the turbo connected, I run it for about 10 minutes until smoke comes from the valve cover, might need to cool it better
