question asked Charles of the design;
''Looking at your ASP 4-2-1 budget header does it matter that the runners are paired different to most other 4-2-1 SR20 headers?
These runners are paired for best mid to high RPM scavenging. It is designed and built this way ie as a long runner setup''
sam - it's a 4-2-1 header not 4-1
dale - Clearance is fine it sit maybe 5mm higher than the lowest point of the engine cradle. Which I don’t have a problem with on just spring.
