Top end bog issue.

[Sunvang]

Im seeing around 5psi on the boost gauge, no jumping around. I also changed the boost adjuster to a torbonetics boost adjuster. Works great.

Your problem is not Enought air flow under the hood..

Try to take away snow on your hood, and retest.

The sled is almost on choke after few sec, since its no air left.

100% its your problem

Really now thats 100% his issue? Im sure your 110% WRONG. Sunvang when you own a turbo you will have to go over the sled.

check all hoses and clamps for leaks
check your exhaust for leaks ( welds, exhaust donut, bolts that hold your turbo if there loose, springs missing?
your af is going rich or lean what one is it??? Its not staying at 12.3 like you stated its going up or down when you get the bog
Did you make changes to your fuel box? Did you try pulling a little fuel? Are you ridding at way lower of elevation then the last time? Is the air way colder or warmer than the last time? all that makes a difference
Did you change plugs? Is you plug gap correct.

You are right, that was not my issue, tested it today

check all hoses and clamps for leaks
Will do tommorow
check your exhaust for leaks ( welds, exhaust donut, bolts that hold your turbo if there loose, springs missing?
exhaust is checked, not missing any springs, no welds cracked, echaust donut looks good, havent checked the bolts holding the turbo tough
your af is going rich or lean what one is it??? Its not staying at 12.3 like you stated its going up or down when you get the bog
When riding full throttle on the road when it works im at 12-12.5. When it bogs it goes way up to 16 something before i release the throttle
Did you make changes to your fuel box? Did you try pulling a little fuel?
Tried to put green blue down from 3.5 to 2 and it didnt do any difference
Are you ridding at way lower of elevation then the last time? Is the air way colder or warmer than the last time?
Elevation is the same, it alittle colder but not much
Did you change plugs? Is you plug gap correct.
Tried to change plugs and increase the gap last time, helped alot with the bogging, adjusted the plug gap down to stock and it went into bog again. Will try with new plugs and recommended plug gap tomorrow if i can get ahold of some

So if it goes up to 16 af like you say that tells you its going lean right? so your starving fuel. Pulling fuel was not the way to go on the box. If anything green blue should have gone up. if your shure your box was correct start simple, change fuel filter if thats not it check fuel pump..

 

[piper]

I still think the problem is not enought air..

i had the kit sunvang own to day on my sled last winter, when it was alot of snow, it could start to act like the same when the hood and every think was full of snow.

i will call you tomorrow sunvang

shouldt the Afr go down if it had leaks..?

But it only goes up to 16 after it starts to bog, and while its boging. When im riding on the road with little traction on the track, its runs good a WOT with a a/f reading of 12-12.5 and rpm at 8100, but as soon as im driving on snow where i get more traction it bogs then starts to go into over 15 in a/f ratio.

Could it be plugging the exhaust?

That is what they sound like when they do.

 

[Sunvang]

I know it does sound like that, but my skis are in the air and it still happens.

you are going too rich when the engine is going on heavy load....even if you see 16 then ---- it can be rich or lean ....when you are out of max and min parameter on the afr gauge it shows ---. just by the sound of it, i can defenitely tell you you are too rich(i would also check your reeds for some litte damages). lower your green blue(fuel added per psi) and test WOT in deep snow , when you get it right, tune your green,yellow and red after that.

p.s.: if you had one of our standalone, you would simply go out on a ride and press f8 on laptop(datalog) and after a short pull with the bug coming, simply stop, press f8 again, and go to logging function and check all sensors on the sled(in graphic mode) and you could clearly see where and what is your bug(ex:real afr reading compare to afr target ... then too rich!)
please guys do not go crazy because i gave an example of how easy it is to resolve little issues like that with the standalone.....i didn't want to promote but help out.

Thanks for the tip, but ive already tried lowering green/blue but no difference. Took it for a spin yesterday and worked great on the trails, but starts to bog quick after hitting deeper snow.

Thanks for the advice on your standalone, but I still think the price is way to much.

Where is your intake at?

 

[dcturbo]

Fuel filter. would be where I would start.
We have replaced two this year already.
Not as much of a load on the trail as there is in deeper snow

 

[Sunvang]

Under the hood.

Wil check that out thanks.

WHERE IS THIS UNIT FOR THE TURBOS?????????

[theshadowrider]

Under the hood.

I had similar problem and learned it was due to me sucking snow and steam. The only way I could get mine to run good in the deep snow was frog skins, and get rid of my mesh vents. Had to go to gill vents and frog skins. You would open hood and ther wasn't snow on my prefilter covering my intake but there was condensation under my hood. The snow was coming in really fine amounts hitting hot parts creating steam them the turbo sucks in steam. Makes your sled go rich. FYI excessive rich shows up as lean on afr sometimes. I figured this out when someone told me this, but I didn't believe them. I would of thought I was getting exhaust plug but I was running tunnel dump. So to test this theory I took some heat tape riding. When it started to bog I tapped up all my vents and seams. What do you know it ran great. When I got home t took off my vents and ordered gill vents and frog skins. Just an FYI.

 

[Sunvang]

Thanks Shadow, will keep that in mind Will try to test some more today, still havent got the correct plugs yet tough, nobody around me sells them so have to order online, and that takes some time

 

[Sunvang]

Could this be my boost leak?? BOV sticking?

 

[Sunvang]

Also, tried the sled for a trip and i deffinatly leaks boost. Where i saw 5-6psi before, im now only seeing max 2psi. Checked all the hose clamps and they looked good, thats when i doscovered the BOV beeing greasy. But dont got any tools here at the moment, to open it and clean it.

 

[Boston Racing]

The BOV sticking could cause an issue.
