S13 SR's actually have the highest redline at 7500 RPM
S14 and S15 SR have a redline of 7250 RPM
The S13 SR has a higher redline because it has a a "high-port" intake manifold. The higher ports give you a straighter shot into the combustion chamber. The "low-port" SR's (S14 and S15) have smaller ports and a tighter bend leading to the intake valves. That's why the S13 SR has a higher redline. Those redline numbers are where the redline starts on the tach.
