I assume you mean a Boxster S. I base Boxster would not hang with the SS. In that speed range, a 986 S would probably run about even and a 987 S would likely outrun the SS. What's interesting is that putting headers and exhaust on the SS does very little. The SS has pretty open breathing system. The HP difference in the Z-28 and SS is due entirely to intake, header and exhaust. There are not many aftermarket products that actually out perform the stock SS set-up

I have an slightly modded LT-1 Z-28 and am in a club and attend events often. My best friend has an LS1 Z-28 with I/H/E modifications and I drive it often. My opinion is based on a fair amount of experience with those cars.
