Turbo on older tractors

super99 · Nov 14, 2011

In some of the tractor magazines I get, there is a ad for turbochargers on older gas tractors, M thru 450, 77 &88, WF thru WD. Does anyone have one of these on a tractor and how you get along with it? Is it for show, pulling or working?? I have a Ollie 77 that I would like some more power out of, just wondering.

Lots of guys do it on the pulling circuit, cooling can be a problem, a friend uses e-85, and a big carb, and a turbo from a rice-burner, to boost his CA Allis, to over 75 HP. We have a guy in the local club who has turboed 2 cyl diesel JD's, Lots of good shade tree mechanics, can tell you how.

An engine needs a fairly low mechanical compression-ratio to hold up under turbo-boost. A turbine-driven supercharger (turbo) raises the "effective compression ratio."

Most older farm tractors have very low CRs, but Oliver is know for having some of the highest compression ratios ever used on gas farm tractors. Off course, not all Olivers.

I have seen a fairly stock mta gas with to4 turbo and wastegate making around 10 psi at about 80 horse on dyno.

It can be done but it isn't going to be cheap. If you are talking a work tractor I think you would be money ahead to just get a bigger tractor. The extra HP you will gain is going to be driving a tranny designed for a lot less HP and Torque. That's going to translate into breaking something......expensive!

Dad and I put a turbo on a old 88 Oliver diesel. We did not use a kit. The turbo we used was from a IH engine. NO WAY was it correctly sized to the Oliver but it did add HP because before we added the turbo you could load the engine into smoke. after the turbo was installed you could no longer make the engine smoke UNTIL we turned the pump up. It has never been on a Dyno but it was one time on my Uncles saw mill. He thought the tractor was making around 55 to 60 HP. He normally use a 190 XT Allis on this mill that had been converted from belt to PTO drive.We can not turn up the old Oliver to far because it only has splash lubed rods.

I have a turbo kit from Keystone turbos on my Super M. I use it for pulling only. Its making around 15 lbs of boost and its pulling 95 horse on the dyno. All the "inners" of the engine are factory componets set at factory specs. I have did alot of govenour and distributor and carb work to get it to 95 horse. There are videos on youtube under farmerboy2003 of it pulling. I pull form 5500 pound class up to 12000pound class. Check out the videos, you'll be impressed im sure.

As for a practical stanpoint the turboing a disel is simple but lots more to consider on your gas burner. You could better spend you time on things like overhaul, bigger valves, more carburator, improved ignition, and probably get more for your effort.
