14 pro bully dog silber bogging
- Thread starter jason leckner

That is why I recommended trying to either a quick bypass of the tether or check the adjustment of it. My Pro Armor did the same thing.
Did you install the Polaris replacement TPS connector/harness from the older IQ's or did you replace the whole harness?
mine now only bogs after a long wot pull goes fat. I think all the low bogs are over rev . 1 turn of my boost controller I can get the bog every time. if i run 8100 on the trail for my boost i am good in the deep for the most part. i still want a new mapp for the long throttle bog
I don't think I agree that all are bogging due to over rev, I was running lower boost to keep my r's down in the 7900 range to test that and it still did it. I think Corey has explored this possibility as well. It might have been the issue with yours but I don't think it is the issue with all of them, something for people to try though. Has anyone else tried the clutching mentioned in page 3 from ephrafarmer? He went to the other angle on the helix and a 180-300 secondary spring.
I still have the bog but not near as bad when I set up my sled to pull 8200 on a full heavy pull. As soon as the track lets loose it will over over rev, period.

Here's an update on my search for answers...
I took my sled in to have the TPS adjusted on Monday. It was out... We also realized that my Pink primary spring was broken. Replaced it with a Red/Almond and now it engages much smoother. The Pink slammed in and would slip the track too much which can make you trench.
Rode yesterday in plenty of fresh medium to heavy density fresh snow. Here's what I noticed...NOTHING. Sled pretty much ran the same as before. Moments of arm pulling glory sometimes followed by a studder or bog that sends you over the bars.
I rode with a buddy who has the same kit and his runs AWESOME! Perhaps some silver lining...My other friends that were with us pointed out that his sled (the one that runs awesome) has a much louder pronounced sound coming from the BOV. After paying attention to that I would agree. So on the way home I took my sled back to the installer (the same guy did both) to see what he could see. One side note that I realized as an issue...When I turned my boost up from 8.5 to 11 I would see really no increase in RPM.
After inspecting the BOV my installer just told me that you could blow through the BOV like it wasn't even there. He said it had garbage (aluminum shavings) in it keeping it from closing and spring that was so weak that as the boost would come on it would just open the valve further. This possibly could be playing some huge games with what the ECU is reading and what the motor is actually seeing.
Has anyone else checked their BOV? Perhaps there are some quality control issues where they are made that are contributing to the problem.
Unfortunately, I will have to wait till this weekend to verify further...

The surface area above the piston is larger and therefore creates more force Than the same pressure in the charge tube. I actually put lighter springs in them.....

Just to clarify...Is it your opinion that based on what I wrote, my BOV is acting as it was designed and setup in this application?
If you can blow through it from the charge tube side that's normal. If you really want to test it apply the same pressure to the fitting and the charge tube side and see if it seals. Blowing through it from the charge tube is is just overcoming the spring. Boost pressure is what seals it. I just took a spring out all together and the blowoff still works
who is did you install? has anyone done a leak down test? where did you ride last week end?
I've tried springs thatvblow off with 2psi, 5psi and 10psi boost. It does change the sound but made no difference in how it runs. But in an older kit I had the valve would stick from the oring being too tight, needing lube; And that caused issues. So if your blowoff valve wasn't seating properly maybe you'll have some luck and that's ur issue.

This is blue mt escape. I am still having issues with my 13 pro and silber turbo. I have been to the dealer many times and you think you find something and change it and it still does the same thing with the bog. We are in Togwotee right now and it is deep and the thing runs like ***. Would better off with a stock sled than this thing! Very tried of the problems, not what I paid For

I can't believe Justin has not come up with a fix. I am sure its not easy, but he rep is on the line now with more than half the season over. It will be hard to sell kits next year with no fix in sight.

I agree, I have been trying to stay very optimistic about him and the rest of the guys working towards a fix before the season is out.. In hindsight I should have listened to all those that warned me about going this route.
Expensive lesson learned I guess

Who makes his BOV? My sled ran great yesterday for half the day. It may have been a fluke, but I think the bov was functioning properly and then started to stick. Once it was stuck open it my theory is that by being stuck partially open it is calling for more fuel than it actually needs. Therefore loading up by the ecu dumping more fuel than is necessary because some of the boost is blowing out the stuck valve.

The piston on my bov doesn't move very freely. Feels a little scruffy. I really think it might be sticking. I pulled it apart today, pulled out the spring and stuffed a little rag in there to seal it off. I rode a little bit today from the cabin and it ran great. I do want to stress that I only rode a little bit. Probably not the best indicator if this fixed my problem but it's a good sign...
Does anyone know if any of the sleds that Silber took out that had problems blocked off the bov to see if that made any difference?
