This article describes the process of fitting a nose block to the wheelwell and A-pillar of a race car. The author explains the importance of proper fit and the steps involved in shaping the block to achieve an aerodynamic profile.
The first step in fitting a nose block is to create a template of the wheelwell and A-pillar. The author recommends using a paper template or cardboard cutout to ensure accuracy. Once the template is created, the nose block can be cut to size and test-fitted to the car.
The author notes that the nose block should fit snugly against the wheelwell and A-pillar, but also have enough clearance to allow for suspension movement. They recommend leaving a small gap of 1/8 inch to ensure this clearance.
With the nose block in place, the author then plots the profile points on the side of the block. These points indicate where the surface of the block should be shaped to achieve the desired aerodynamic profile. The author emphasizes the importance of accuracy in this step, as even small deviations can have a significant impact on performance.
The shaping process typically involves using a hot-wire cutter or other cutting tool to remove excess material from the nose block. The author advises working slowly and carefully, constantly checking the fit against the car to ensure proper clearance and aerodynamics.
Once the nose block has been shaped to the desired profile, the author recommends using a sanding block or other smoothing tool to achieve a smooth surface finish. This is important for reducing drag and improving airflow over the car.
In conclusion, fitting a nose block to a race car is a complex process that requires careful planning and attention to detail. By following the steps outlined in this article, however, racers can achieve optimal aerodynamics and performance on the track.
