Sprint Car Header 1-5/8 -1-3/4 Crate Engine

The Sprint Car Header 1-5/8 -1-3/4 Crate Engine from Schoenfeld is purpose-built for high-revving sprint car applications where extracting maximum horsepower from a crate engine package is non-negotiable. Designed for racers and fabricators who demand precision-engineered exhaust manifolds, this header is engineered to optimize scavenging efficiency across the RPM band, reducing backpressure while maintaining proper flow velocity.

The 1-5/8 to 1-3/4 inch primary tube sizing is engineered for small-displacement crate engine platforms, providing the ideal balance between scavenging velocity and collector design for high-RPM operation. Schoenfeld's construction utilizes mandrel-bent tubing and precision-welded collector sections to eliminate dead zones and turbulent flow patterns that rob horsepower. The stepped primary design transitions from 1-5/8 inch runners into larger 1-3/4 inch sections, optimizing pulse energy management and improving cylinder evacuation efficiency.

This header is ideal for racers building or maintaining crate engine packages in sprint cars, midgets, and specialty racing platforms where Schoenfeld's proven engineering standards are expected. With its focus on performance and efficiency, this header is a critical component for any competitive build aiming to maximize horsepower and improve overall race performance.
