Circle Track vs. Drag Racing Engines: What Makes Them Different
Not all performance engines are built the same. The setup that dominates a circle track won’t survive long on the drag strip. At Fastime Performance in Taylor, Michigan, we build both — and we understand what each discipline demands.
Power Curve and RPM Range
Circle track engines need to make consistent power across a wide RPM range for sustained racing. Drag racing engines are tuned for short bursts of extreme horsepower and torque at the top of the RPM curve. Cam profiles, compression, and valve timing are all adjusted to suit those goals.
Durability vs. Maximum Output
Drag motors can push limits because they only run for seconds at a time. Circle track engines must endure repeated heat cycles and long races. That means different choices in materials, clearances, and oiling systems to ensure reliability lap after lap.
Custom Machining for Each Type
At Fastime Performance, our machining and assembly process is tailored to each racer. Whether you need sustained mid-range torque or a high-revving top-end setup, our shop can blueprint and balance your engine for the perfect combination of power and durability.
