Innovative High Performance drive components made by Mercedes-AMG, electrified turbo charger


Dear Sarge,

Recently I received in my e-mail box a UTV Action news story about an electric turbocharger. While that is interesting, isn’t the unit acting as a “supercharger” until the exhaust flow increases beyond the capacity of the electric motor? Inquiring minds want to know!

Private Worthless, you must be referring to UTV Action’s report on electric turbos: https://utvactionmag.com/will-electric-turbochargers-boost-utv-performance/ Obviously, you have an intimate knowledge of internal combustion engines. Essentially, until exhaust pressure exceeds the capacity of the electric motor inside the turbocharger, it is acting as supercharger. For the E1 boots, a supercharger pushes air (boost) into the intake and is powered by a belt from the crankshaft. The main difference with this electric-motor-powered turbocharger is, regardless of the exhaust pressure or crank speed, there is constant boost pressure at the intake that gives the operator instant throttle response. This innovative setup eliminates the main problems with both the supercharger and turbochargers—throttle lag at low rpm. The supercharger has low boost at low rpm because the crankshaft pulley driving the supercharger isn’t spinning fast enough. But, the supercharger will respond quicker to throttle up than a turbocharger, which has to wait for the fuel to be burned and exhausted to power the turbocharger. Boot, if your MM score from the ASVAB is at least 95, then I strongly recommend you consider an MOS change to 1341, 1345 or 2146. Dismissed!


Dear Sarge,

For our farm, we purchased a 2019 Mahindra 750b XTV at a farm auction. The auctioneer couldn’t start the XTV because there was no battery installed. We pushed it to our flatbed, winched it on and brought it home. The next day we went to the local Mahindra dealer and purchased a battery and installed it, but after installation, there are no lights or display, and the key appears to do nothing. We checked the cable connections, and they appear to be correct—red to positive and black to negative. Next, we checked the fuses and everything is good. Our local dealer isn’t really oriented to UTVs—more tractors and farm equipment—so they are not much help. My son suggested I turn to you for a manual and correcting our power problem. Here’s hoping you can help us.

Private Rusty, the 750b’s have an unusual battery cable setup, and it’s really not surprising that without a manual you would get the cables wrong. However, it is surprising that your dealer couldn’t even provide a manual for you. So, here is where you can download not only an operator’s manual but a parts manual, too: https://intimidatorutv.com/owners/manuals/2019. Yes, Boot, your Mahindra was made by Intimidator. Now, to correct your battery wiring problem, because there is most likely nothing wrong with your Zooter; it is just the battery wiring. Generally, a red wire on the battery indicates (+) and a black wire indicates (-). But, not on your Zooter, Boot! There are two large black battery cables—one small black battery cable and one red cable. The red cable and a large black cable are connected to the (+) side, and the other large black cable and the small black cable are connected to the (-) side. As you have already noticed, the black cables that are zip-tied together do not go to the same (-) terminal. When you get the correct black cable on the (+) battery terminal, use some red electrical tape to indicate which one is (+) and re-zip-tie the cables together based on function. I hope both you and your son are ready for an easy five-mile march with full pack. Move it, Boot! Dismissed!


Dear Sarge,

Back in 2018, we received the Marine utility task vehicles, and we have been using them in Australia since. It is my understanding that we will be getting new, improved utility task vehicles to solve some of the problems we have experienced. Do you know what has been fixed and what has been ignored? I am sure you have access to most everything available, and we were just wondering what helmet do you prefer to wear, because we have a pool going in our unit as to which helmet you prefer?

Boot, you are correct. The Polaris MRZR-D2 and D4 Zooters procured, in some ways, simply didn’t cut it for Marine use! Because you Boots insist on hitting every rock you can see, and some you can’t, high-clearance A-arms will be installed. The plastic floorboards will be upgraded to aluminum to prevent punctures (again, from you Boots hitting everything you see). Polaris is stepping up with an upgraded clutch kit. All the Zooters will be fitted with upgraded BFGoodrich tires, and these tires will be fitted with 16 Tireballs to prevent flats. Polaris will also be providing an “environmental protection cover” (read as a roof) to each Zooter. Each Zooter will also get a kit containing turn signals, a horn and a rear-view mirror for road marches. As to your last question, Boot, yes, I have tested many helmets. Some I like and some I don’t. If I have a rapid deployment, I would go old school with a PASGT style, LWH, first generation, upgraded with the PASGT Parachutist (PIL) foam impact liner. Not the answer you wanted, Boot?! You asked and I answered! You and your platoon can count off 25 for each question! Dismissed!
