“Very impressed that I am now running 15º cooler and my kids and wife no longer run it hot!”- Lonnie Liermann
Nothing is more impressive than a clever idea that no one expected. MSV Racing pioneers powersports cooling
The MSV Racing Banshee Impeller/Shaft easily outflows and out cools any other Banshee impeller/shaft on the market and achieving +2.0 GPM more average flow vs OEM and +1.5 GPM more average flow vs the aftermarket AND outcooled them by up to 14ºf.
Increasing flow reduces the cycle time between the engine and the radiators providing far better engine heat removal.
Let us point out the trick features that made this happen:
- The impeller was designed to optimize the banshee’s volute area boosting flow, efficiency, and is made from 7075 T6-511 aluminum.
- Precision ground 304 stainless steel was used to make the shaft which incorporates a reduced shank at the cooling port pass through. Specifically designed from FEA testing to maximize flow through the inlet port, reducing back pressure, and turbulence into the impeller while not compromising required strength.
- We DLC coated the impeller shaft for extreme durability. This very hard (2500HV on the Vickers hardness tester is three times the hardness of heat-treated steel and over two times the hardness of a hard chrome coating.), self-lubricating coating ensures zero shaft wear, ultra-low seal drag, and prolonged seal life. The shaft will never wear out!
NOTE* For every 1 HP added to the stock Banshee engine you are introducing 2500 BTU into the OEM cooling system. So, add 25 HP to the stock Banshees 35 HP and you introduced 62,500 MORE BTU’s of heat. That is a 40% increase in heat added that the OEM cooling system must try to remove. Keeping your Banshee out of heat soak is key to maintaining max power longer!
MSV Racing Banshee kit includes impeller and shaft, Custom laser cut gasket and the Koyo Bearing.

I built this Banshee for my wife and kids. When I ride the temps are fine but when they ride it they tend to run it hot. I run the Macdaddy impeller and after reading about this impeller and talking to Jason I wanted to give it a try and would report back. After testing I found out the Macdaddy was far from the best!
Oregon Coast Sand Dunes, Winchester Bay:
Banshee Hill
Ambient Temp 64º
Mostly sunny with very light breeze
Banshee Build:
T-5 Pipes
Keihin carbs with pod filter
4º advanced timing
Dune port
Stock radiator
Cool Head
Inline heat sink with temp gauge
Sonoco 110 w/Yamalube a 40:1
Warm up to 140º
Five hard pulls up Banshee Hill back-to-back-to-back….. with no cool down.
The ATV got no hotter than 165º.
This ATV runs consistent 180º with Macdaddy impeller!
Very impressed that I am now running 15º cooler and my kids and wife no longer run it hot!

was running vitos but the shaft wore out. the black msv coating is super smooth. first ride over the memorial weekend. ran cooler than I remember. winner

I have the MSV Racing impeller in my CR500 that works awesome so it was a no brainier for me to buy the Banshee impeller. I bought the Banshee Impeller kit, optiflow Radiator Cap, supercool, and the redline gear oil all at once. Fast shipping and now my Banshee runs cooler in the desert.

I needed to replace my impellar shaft because my oem was groved. I never want to replace the shaft again. I saw the msv kit and talked with Jason he said to read about diamond like carbon DLC and after that i was sold.

I did the initial testing on this impeller at the Oregon Dunes. A few things impressed me. The part is beautiful! Hate to hide it away. Funny how no one else thought about the reduced shafts size and the DLC coating on the shaft is amazing!
Doing the hill shot testing and then riding the dunes with the MSV impeller the Banshee never lost power when being mercilessley flogged by my 315lbs where my P.D impeller would show power loss due to engine progressively getting hotter and hotter after the second long hill shot. If the shaft never does wear out this impeller/shaft is a steal.
