I am putting a pyrometer gauge on my 4020 that has an m&w turbo on it. what is going to be better, probe before turbo or after? and what will the temp difference be between the 2 two locations? directions for gauge says it is better after the turbo but their is a spot before the turbo where their use to be one. thanks

I always refer after turbo! If and when the probe brakes or parts fall off they wont cause any damage to the turbo. I can't remember exactly but 300 degrees is what is stuck in my brain.

Did you get any instructions?
I would put it after the turbo. I believe there is a certain distance that each manufacturer wants their probes/thermocouplers installed at. (5 inches, behind turbine fins; is what comes to mind)

I have personally never seen a probe after the turbo. Doesn't mean it won't work but there must be a reason so many are placed in the manifold.
Also, I suppose things have changed but back in the day when that tractor was the work horse, there were two kinds of 4020's with turbo's, ones that had blown up and ones that were going to blow up.

i bought this tractor to mostly pull my 1750 no-till corn planter, occassionally to work some ground. so i it is not the main work horse. so from the responses i have recieved i am going to assume to put it in the spot that is alrady their, before the turbo. I was told 1100 was the temp i didn't want it to go over. is that with probe before or after the turbo since their is a diiference in temp reading between the two. thanks again

I would say that 1100 F would be the spec for After the turbo. (Most semi-tractors, are after the turbo and rule of thumb is not over 1200F)

I had a 4630 that would bump 1100 F, the probe was before the turbo. I was told by the mechanic that intalled the pyro not to exceed that for any length of time. Given the issues 4020's used to have, I don't think I would push it that far.

I would put it before turbo....more accurate measurement and you know what your cyls are standing up to and you know what temp air the turbo has to deal with.
