With track/drift/rally cars the heater matrix, air conditioning and front and rear door glass is often removed to save weight and increase power.
Pro Race/Drift cars have their door glass removed and the electric or mechanical window mechanism to save weight. Pro Drift cars remove and replace door glass with clear plastic as flying stones from other cars drifting can shatter the door glass when going sideways. This can cause injury to drivers mid drift, and or cause a distraction. Door glass is replaced with a special type of clear plastic, and this leads to a hot stuffy cabin with no fresh air or ventilation. We have a range of cockpit ventilation options to help bring in fresh air into the cabin, which can be mounted directly on to the plastic windows.
When removing the heater matrix and/or air conditioning there is no climate control within the cabin. This can lead to condensation on the front windscreen in colder climates, which negatively impacts driver visibility. We would recommend installing a lightweight heater to reduce/remove condensation. Again, in colder climates a heater maybe necessary and we have a variety of different heaters which can be used to bring the cabin/cockpit into a comfortable temperature.
“Better” depends on the situation. Air conditioning provides superior cooling, which is crucial in extreme heat and can maintain consistent engine temperatures. However, AC systems add significant weight and complexity – both things performance drivers try to minimize.
Ventilation, especially forced ventilation with strategically placed fans, offers a lighter-weight solution for managing cockpit temperature. It won’t cool as effectively as AC, but it provides airflow that reduces humidity and prevents fogging—critical for visibility. For many track day enthusiasts removing the bulky AC system is worth the trade off.
We cater to drivers who prioritize weight reduction. Our ventilation solutions provide a balance between cooling, defogging, and minimizing added mass – ideal for cars where every pound counts. It's about finding what works best for *your* driving style and goals.
The cost of repairing or replacing a vehicle’s ventilation system varies wildly. A simple blower motor replacement might be $150-$300, including parts and labor. However, if the heater core is leaking, or the evaporator core needs replacing (requiring AC system evacuation), costs can easily climb to $800 - $2000 or more.
For stripped-out race cars, a complete aftermarket ventilation solution – including fans, ducting, and mounting hardware – typically ranges from $100-$500 depending on the complexity. We offer kits tailored for vehicles that have had their stock HVAC systems removed, offering a much more affordable alternative to a full system rebuild.
It's also worth noting that labor rates vary significantly by location and shop. Getting multiple quotes is always recommended before starting any repair work.
A typical car ventilation system draws outside air, filters it, and then conditions it—either heating or cooling—before distributing it through vents inside the cabin. It uses a blower motor to force air through ductwork. The key components are an intake (where air enters), a filter (to remove dust/pollutants), a heater core (for warming), and sometimes an evaporator core (for cooling, part of the AC system).
Ducts direct airflow to vents you control—face vents, floor vents, defrost vents. Modern systems often have blend doors that mix hot and cold air for precise temperature control. In performance cars, removing weight by ditching these systems is common, but it creates problems with visibility due to condensation and driver comfort.
That’s where aftermarket options come in – we offer lightweight fans and ventilation solutions designed for vehicles lacking a full HVAC system, ensuring you stay cool and have clear vision on track or during spirited driving.
There are generally four main types of vehicle ventilation: natural, forced, gravity, and mechanical. Natural ventilation relies on air flowing through openings – like cracked windows – but isn’t very effective for serious heat or humidity. Forced ventilation uses fans to actively move air, often seen in older vehicles with simple blower motors.
Gravity ventilation utilizes differences in air density; hot air rises and escapes while cooler air enters, though it's limited in control. Finally, mechanical ventilation – the most common today – combines a blower motor, ductwork, and vents to deliver conditioned air (heated or cooled) throughout the cabin.
For stripped-out race cars, where stock systems are removed for weight savings, you’ll often find drivers using simple forced ventilation fans mounted near window openings. We specialize in solutions that bridge this gap – providing effective airflow without adding unnecessary bulk.
