Amateur Race Car Interior Preparation: Acura Integra : New Acura New car review 2008
by Craig Markusic
One of the most crucial factors that will make a race car competitive on the race track is the weight of the race car. The typical race car, however, that is used in amateur auto racing is a street car that undergoes modification. And one modification is the removal of many parts of the interior, which may reduce 10 to 15% of the curb weight of the car. When parts of the car’s interior are removed, horsepower is freed up to add speed. But speed is not the only basis for the interior preparation of a race car. In this article, I will describe the preparation of the interior of the Acura Integra that will race in the Honda Challenge 2.The Acura Integra has raced in the SSB (Showroom Stock B) category in the SCCA (Sports Car Club of America). The SSB rules require that the majority of the interior be intact with some allowances for installation of the roll cage and a racing seat. The Honda Challenge rules allow the removal of just about everything with the exception of the instrument panel. This meant that all of the carpet, front passenger seat, trim pieces, and mounting brackets can be removed. The HVAC (Heating, Ventilation, and Air Conditioning) stuff under the instrument panel can be removed also. This adds up to a lot of weight reduction.I’ve talked to some guys that like to leave these systems intact to keep the windows clear but the potential weight savings was too tempting and I’ve had good success keeping my windows clear with anti-fog treatments. The sunroof looks great on a sports car but unnecessary in a race car. The sunroof can also be removed for a substantial weight savings. The rules allow the opening to be covered with a metallic panel.The sound deadening material under the carpet can be removed for further weight reduction and for a cleaner interior appearance. Even without the need to reduce weight, the deadening material should still go because it is a hazard in the event of a fire. Removing the sound deadening material can be greatly simplified by using dry ice. I’ve tried this in the past with minimal success but the alternative is not viable. The thought of sitting in the car for hours with a scraper and a torch, exposing myself to a potential fire hazard and toxic fumes, led me to try the dry ice again. I’ve also tried wire wheels and chemical strippers. None of these methods were as effective or as fast as dry ice. The key seems to be applying liberal amounts of dry ice over a large area and allowing it at least 4-5 minutes to work its magic.I made some cardboard dams to try and keep the ice in contact with the vertical surfaces around the tunnel. This seemed to work pretty well but may not be absolutely necessary. Once you hear the insulation start to pop and crack a few strikes with a dead blow hammer should be enough to dislodge the material. Be gentle with the hammer as the floor is probably less than a 1 mm thick and can be damaged easily. The remaining residue can be easily removed with a grinder with a sanding or wire wheel. This process also helps to prepare the surface for paint application.
