2018 Hisun Sector 750 Crew Excessive Sound

Recommended Posts

So i have a 2018 Hisun Sector 750 Crew and while driving the noise level is outrageous.  I want to find a way to decrease the decibel level, so does anyone have any ideas!!! i was thinking about installing foam on the roof enclosure and possibly putting something around the engine bay area.  I have not found any companies that makes a suppressor for the muffler...Any help would be appreciated.  thank you

I have a diesel mule that has the intake in the rops bar. It's loud also. A back window tamed the noise to a tolerable level. Since I'm not familiar with your machine, it might not be helpful. But insulating, and deflecting that noisemaker away from the cab would be the way to approach this.

Just a shot in the dark here. But I see those black truck bedliners, on the side of the road that've blown out of a truck. That stuff would be an excellent material to fabricate what you've described.

I used this for good effect - self sticking with aluminum foil on exposed side.

      I'm new to this forum. I recently picked up a Hisun "Coleman" Trail Tamer 800 that was ran way too hard. Trying to learn as much as I can about Hisuns. I have done a complete engine rebuild, replaced the crank, con rods, pistons, rings, head gaskets, base gaskets. cam chains, U joints, front a-arms, replaced all rear pads, repacked trailing arm bearings. Replaced the rear diff with a used one, have a rebuild kit in the cabinet. Put it all together, no spark. Somehow got spark and fuel and it started and purred like a kitten. Pulled the exhaust off to replace the gaskets, replaced the battery and starting relay switch. Turns over but no spark and no fuel again. Have taken apart almost every connection and added grease, still nothing. So jumped on this forum to try and apply any learnings from here to my project. I'm about to pull all of my hair out and Ima already going bald. Any help and input is GREATLY appreciated.

      I recently purchased a 2020 Massimo 400 EFI and  began installing soundproofing to lower the overall body noise.  The model I choose is the crew cab with rear facing seat and diamond plate bed.  
      the first phase involved removing the rear deck and applying Noico 80 mil sound deadening mat over the exposed diamond plate sections of the underside.  This immediately removed the  sound of vibrating metal plate!
      Next phase is to continue this application to the interior of the plastic  around the engine compartment and then any other plastic panel that has a "hollow" sound.   It will add 2-3 pounds to the overall vehicle weight  but it makes a huge difference in noise reduction.  One question I have - there is a vent directly in front of the engine (behind a drivers leg about calf level)  I am strongly thinking about covering this as the level of engine noise here is huge.  The engine is water cooled so I don't think this is a problem as the air input is minimal - but i don't wish to overheat the engine.
      Thoughts?
