Quote from: NMKawierider on May 17, 2021, 08:21:42 PMFinally got to test the Donaldson a little on the last trip. Did this "UN-sientific" review on the findings. Not bad! If this think keeps working like this it will be a while before that S&B sits atop all that plumbing...lol. UPDATE: On 5/27/21 we went for one of the dustiest rides I have ever and although I was able to make the entire day without cleaning the filter there was several times near the end where I needed the booster fan. However, to the Donaldson's credit, I did make it where otherwise there would have been no way. I am however going to down-grade the amount it removes in this application ...to somewhere between 55-65% instead of 80+ %. This may be because of the slower speeds which slows airflow which the unit needs a certain volume to separate and remove the dust. Still...better then nothing....and the first engine air filter still doesn't need cleaning..but I'll probably do it anyway UPDATE 6/4/21: Out of curiosity I wanted to know at what RPM does the spinner in this unit start to rotate. Although all it does is help move dust out the discharge port it does help guide the vortexed air. I slipped one of my bore scopes just slightly in enough to view the spinner's paddle and cranked it up, put it in neutral so the CVT would spin, flipped the pod to read RPMs and up we went. To my surprise it didn't start spinning until 5700 RPM. Hell I never run it that high so it has never spun. I then flipped-on my CVT booster fan to see what effect it would have. It then started spinning at 3500 RPM. Big improvement. I wonder how much better this Donaldson would work if the spinner worked all the time. I could mount a 3.5" fan just under it and blow all the time...but that means moving more air through the CVT then it needs...which also means moving that extra dust through to the filter...shortening the time between cleanings again...defeating the reason to have the prefilter in the first place. So. Either it stays as is for now or...the S&B is in the very near future. NMK I just watched your YouTube 2021 year in review and noticed the Topspin mounted on your intakes. It's been awhile since I've been on here so I had to check it out. As far as I know I was the first to try the Topspin and the Enginaire brand particle separators, my issue is I sold my z500 to my brother in law and he's yet to update me on his filter conditions after at least 200-300 miles. No news is good news I guess lol! Glad you are testing the set up. I paid close attention to the rpms when the separators started turning and mine was i think around 2600 rpm for the cvt and 1800 rpm for the engine intake which assured me they were functioning most of the time. Hope it works out for ya. I've since purchased a 14 RZR XP900 and am fixing it up. I'm entertaining the topspin set-up on it as well. I may return to the CFMOTO product, thinking the cforce 500 or 600, some day...

Seriously impressive!, I would love to have a particle separator and setup like that. Unfortunately, my state is very restrictive with snorkels. I still want to get replace the narrow factory tube with a intercooler pipe and adapt it with silicon elbows to the plastic intake grate or figure out some other stealth solution. Kinda winging it here because anything will be an improvement over the stocker.https://www.maine.gov/ifw/atv-snowmobile/atv/laws-rules.html"26. Prohibited equipment. A person may not operate an ATV that is equipped with a snorkel kit or other equipment designed to allow the ATV to be used in deep water except with the permission of the owner of the land on which the ATV is operated or as provided in section 13159."
The SB seems like the way to go. These have to be wired in right?
How long is the flatbed on your truck NMK? Do you have photo's of loading / unloading?
