Mini Turbo

iternawheel · May 21, 2009

Does anybody know of a small turbo that would fit on a lawn mower engine. and if so does it require an oil line from the engine or is it oilless. and if it does require an oil line how would you plumb it up.

I dont know of any turbos for a lawn mower engine. Turbos require pressure lubrication and lots of oil for cooling, which are things that a small engine like that doesnt have.

Go to Ebay, and search for " Small mini Hitachi ht06 Turbo" It looks pretty small. The bid is at $20.

I stand corrected.After a little searching it looks like some have strapped these small turbos to briggs and honda small engines

Not without alot of work though and external oil pumps and sumps. Have to wonder if its worth it

i suppose there is always going to be those out there that will do it because they can.

but it would seem to me you could get the same power to weight ratios in some crotch-rocket motors or snowmobile engines.

why reinvent the wheel?

A little crude, but.............................

Really, putting that work into a lawn tractor would be better.

That video of a turbo on a lawn mower was , well , SCARY

.

At those rpm's , all I could think of was parts instantly becoming Projectile's rather than engine parts . As mentioned above , if I wanted a souped-up lawn mower , I think I would look at a more powerful type of power plant rather than try to that .

I have a Craftsman mower with a turbo out of a mazda engine. I didn't build it, and I've never started it, but I have it. I got it in with a bunch of parts from a guy in another state. He said he could plow snow at about 30 MPH with it. I'll have to take some pics tomorrow when it's light. I sure looks silly.

Here are a few pictures of the Turbo charger on the mower engine. It's goofy looking if you ask me, but it's still kind of cool.

And you've never driven the turbo'd Craftsman? I'd have made it top priority...... just out of curiousity !

Interesting.

A guy on another forum had something similar. Said it didnt add any power, but it sure sounded cool

I'm pretty curious, but I've never driven a turbo'd anything. I got the impression from the guy that I bought it from that it may be a process to get it started and running. I'm trying to find a time when I can spend some time playing with it.

Thanks for all of the input. After much consideration, i have decided not to put a turbo on my lawn mower, but if i ever come across one and the price is right, i may change my mind. for the time being, i am going to continue to fabricate my 1976 wheel horse into a garden tractor that looks like an international 1086. thanks again.

Probably smart. But, I am eager to follow the progress of your International 1086.

i fabricated the three point and made it go up and down this past weekend. i still have some tweaking to do on it as the arms only go up and down five inches so i will have to try a few different things to get it to work right. i will try to get some pictures of it. it is really starting to come together. cant wait to get it done.

How about a supercharger?; back in the 70's some go-cart racers experimented with automotive smog pumps. With the right pulley ratios they were said to actually worke ok.

Cord · Jun 14, 2009

I do recall people using the old smog pumps. These are the ones used on chevy V-8's back in the 80's.

I used a turbo from a Yamaha Seca on my little Yanmar YM1100 tractor. The turbo is small enough to fit on my hand. Yes, it requires a pressure lube and return line. I used a -3 supply line and a -4 return. The return line turned out be too small and I was blowing oil out the exhaust. I increased the return line to a -6 and all is well. Well, almost. It turns out the oil capacity is so small on my engine that the turbo was cooking the oil. I only had about 30 minutes of run time until the oil broke down and I started to loose pressure. At first I tried a trans cooler, then I added some fans to the cooler. Help, but wasn't good enough. I then stepped up and bought a large oil cooler and electric fan. That finally did the trick.
