Helmet Care

Off-Road races are some of the most grueling, demanding races on earth. Extreme temperatures, remote mechanical fixes, tire changes, dust, mud and sweat. When you get to the checkers it is time to celebrate and your gear is usually just thrown in a bag. When you get to the next race, your helmet is gross. Here are some tips to help keep your helmet feeling as fresh as the day you got it.

  1. Never put your helmet away wet (Not sweaty, not from washing, not from a wet race).  Always leave the shield up and let it dry before storage.
  2. Wipe the helmet down after using it.  Inside and out. Including the shield. A dirty shield will scratch during storage or travel. Use water only on the shield, some cleaners will damage the shield coating. Shields can be protected by using tear off’s or Cruz Armor.
  3. If you have removable interior, remove the pads and liner and wash them.  When the interior gets really bad, you can purchase new cheek pads and liner.  If not removable, wipe the inside down with a damp rag and let dry.
  4. Store your helmet with a spritz of Febreze, Molecule helmet spray, or leave a dryer sheet inside your PCI helmet bag to keep it smelling nice the next time that you use it.

Should I keep my hand mic plugged in?

You just got your new Ultimate package installed in your UTV. As you go through some of the extra parts in the box, you notice the hand mic hanging out there. Your radio connects to your intercom so it may seem like you don't really need to bring along the extra parts, but we have some points for you to consider about that!

We understand that you will be wearing headsets or helmets (both of which have microphones built in) while you are riding.  The hand mic comes into use when you are stopped, resting, waiting or making a repair and you don’t have your helmet/headset on your head.  You can simply plug the hand mic into the front of your radio and communication with your friends or help is much easier.

That said, we DO NOT recommend you leaving your hand mic plugged into the radio at all times. Every time that you push your push to talk button on the steering wheel/grab bar the hand mic will be activated in addition to the helmet/headset mic.  This will introduce unwanted background noise into the system.  Simply keep your hand mic in a tool bag or storage area until it is needed; and you will be happy that you have it with you. 

We also recommend keeping the mic jack cover installed on your radio when you don't have your hand mic plugged in. This helps keep dust and water out of the inside of the radio. Lost your mic jack cover? Buy a replacement here

Microphone Placement

Most people don't know, but microphone placement is one of the single most important components of your communication system. At PCI, we use noise canceling microphones that are specially designed to pick up your voice - not your engine, wind or shock noise. For the microphone to best determine what noise is what, the mic literally needs to be touching your lips. If you are having a hard time hearing anyone over the radio, ask them "how far away from your lips is that microphone?" If their answer isn't, "It's touching my lips!" then it is too far. When a co-driver has a microphone that is too far from their mouth, drivers will often turn up their volume, introducing other noise into the intercom system.

Always have the microphone centered left to right and top to bottom directly in front of your mouth and project your voice directly at the microphone. This is even more important for soft spoken people and children. DON'T YELL! You should never have to yell into your microphone, in fact yelling or excitement often makes you even harder to understand. Try to remain calm (which can be tough in a race environment), relax, take a deep breath, know what you want to say before you begin speaking, and clearly talk out, directly into the microphone.

These tips apply to anyone with a helmet or headset, get some mic socks and get comfy with your microphone - it will make the person on the other end of the radio a much happier person!

The truth about CFM

Fresh Air systems in the racing industry are measured in CFM because that's the number printed on the fan. That number may be accurate at the business end of the fan out of the box, but a lot more comes into play when you add a housing, ports, hoses, how it's mounted and how the hoses are run.

Different motors and housings create different torque and will more effectively push air through a hose and into your helmet.

Part Velocity (ft/min)
RaceAir Boost 3200-3600
RaceAir Max SingleDual and Quad 2700-3200
RaceAir Flow Single 2400-2800
RaceAir Lite 1600-1800
RaceAir Mini 1200
Competitors M3 3000-3600

All numbers above are measured using a digital anemometer at the end of a 6' RaceAir hose. The range is due to different angles/bends of the hose we tested during the study. Keep in mind when mounting your RaceAir hoses, several bends will decrease airflow. RaceAir Mini number is measured at the output as it is mounted directly on the helmet without a hose.
