I was curious how many guys run egt gauges with there turbos. I am getting everything together to do my install on my 2012 pro and was thinking of putting a koso gauge on, but from alot of videos that i have seen with silber turbos nobody really seems to run them. thanks
koso egt gauges on silber turbo

- Start date
I wouldn't buy a set but if you had one then it cant hurt. I bet if you had both you would watch the AFR 99% of the time.

I'll be running one on my Silber turbo this season. Last year I just had the AF. I'm doing this more out of curiousity than anything. I kinda what to know if its running on the ragged edge or if Its really safe. Maybe I will have something to gain who knows. I feel the sled runs good, but AF only tells part of the story.
I'll post some results when I have them.

I run them and them only on mine. EGT probes don't burn out when you use leaded fuel and I can see what each cylinder is doing independat of the other. Personal choice I guess, but I just got use to EGTs on the big bores and that's what I prefer.

I'd like to here some more feedback from people who have run these on turbo Pro's, especially Silbers.
I got mine installed the other day and was able to test it out last nite and this morning. The mid range runs hotter than I'd like to see. I knew I would see it cheap up running down the trail in the mid range, but even holding it steady half throttle sidehilling or carving through the powder it gets over 1300 deg pretty quick. This is happening at times were I ran the sled all last year thinking things were fine and dandy. 1300+ deg isn't fine & dandy in my books. Ignorance is bliss! Wideband A/F's are spot on perfect. I have to really chop the throttle to keep it under control. Under WOT it is fine, 1200deg at most, usually around 1175deg.
Is there any settings I can adjust to help this?
Anyone else experience something similar?

Up your green and see if it takes care of it. Best thing to do when you see the 1300 is too look at your fuel controller and see what lights are on then adjust those light for more fuel.

That's my plan the next time I get out. I was doing this testing back at home at low elevation. I didn't want to do too much adjusting since I normally ride 8000'+ in the mtns. I have a trip planned for next week so I'll do some tuning then and report back. I have a feeling that I'm going to see similar #'s out west though. We'll see.
There is tons of timing in the mid range thats why you see a spike in temps. 1300 can still be safe depending on where your probs are in the exhaust. 1350 is around the point to start worry.
you dont want egts on a turbo sled. 
..lmao.... tune with the plugs and the piston colors.....
but actually if you have the sled spot on and you then add a egt, its pretty nice because you then know (be it 900 or 1500) where it likes to run. And btw in 30 years of this stuff ive seen engines run perfect at 1450* and melt to the wrist pins at 950* Just like anything else its just a tuning tool.

Absolutely correct 1300 isnt scary ,neither is 1150 midrange with your fuel setup on EGT ---
