What moline tractors had a factory turbo kit that you could
have a dealer install back in the day? Thanks for the info.
 
From what I have heard, the factory turbos were mostly for higher altitudes for the LP models....Not 100% positive but that is what Ive heard..unless there were add ons later. I think there might have been on the A4T's. Someone on here will know more about them.
 
I dont think you will find any real "factory" turbos as production models (maybe expirmentals). You could get M&W's and possibly others but the Hi cube low rpm hi torque engines MM designed were not real turbo friendly and not designed to be.We ran one on a M602 but not for long. It seriously did nothing for that tractor. Oh I know they are out there just not factory that I ever heard of...Im sure somebody will argue
 
Weren't they called altitude compensators, think they were dealer installed on the g1355, and the a4ts, might be more those are the two I know of.
 
I think you are right. When I was in Vo-Tech I rememeber seeing an MM service manual that listed turbos, but only for use to restore horsepower to original specification not to increase horsepower. I think at that time, mainly on the G1000s.
 
Yeah, I think your right, they weren't using them for power, know out in Colorado and out that ways there pretty common.
 
I've seen turbos put on the 504 and 585 for pulling, there's a bunch of them on youtube
 
I have what is left of a vista that had an "X" in the serial # that had one on it, I have also seen them on 1050's and A4t's
 
Do you have a picture of that turbo one with the x in serial? And im trying to find one that i can run in a farm stock class type. Its either gotta be factory or add on. Like m&w
 
The only ones I know of that show a turbo in the parts catalogs are in the A4T repair parts and supplement. The 504 diesel used in the A4T-1400 used a turbo on all of them. The 585 in the A4T-1600 had an "Altitude Compensator" that could be added & was listed in a supplement. The MM Engine Company that built 800 pwer units in Russelville, Arkansas offered a turboed THD 800 LP or NG engine.
M&W offered turbo kits for M5 thru M670 diesels as well as for G1000 thru G1050's. I never saw or heard of one for the 900 thru 950's
 
A4T-1400 with D504 engine had "factory Turbo" aka "Altitude Compensator" availble. also some G1000's and other "late" tractors got them added by dealers, as well as some LP-Gas models. the "factory" MM Turbo, was a M&W unit.
 
Here's one on a g1355, 585 diesel someone made found this picture awhile back, the guy said he made it himself and the turbo was from a 1086 ih.

I will give my opinion. I think the turbo or altitude compensator was designed for the 504 diesel engine of the A4T-1400. I read somewhere a few years back that the A4T had a stronger (maybe thicker) crank than the G1000, 1050 etc. and only the A4T crank could take a turbo for prolonged periods such as farming. There are lots of pulling tractors out there with the 504 or 585 engine and a turbo. My cousin has a G1000 that he has lots of fun with.

Only 50 of the 247 A4T-1400 produced came factory equipped with a turbo charger and those were all at the end of 1970 production. I'm sure many more were installed by dealers to increase power of the D504 engine in those tractors. I'm not aware of any other factory installed turbo chargers on Moline tractors.
