Is the 997.1's redline too low?

Recommended Posts

Other P-cars, and most any twin cam six have higher red lines than the 997.1. My 997.1 C2 MT is plenty fun to drive as is, but another 1000 RPM would be high on my priority list of mods. I suppose this is a question for Raby et al. What's the deal with Porsche setting or tuning the 997.1 to such a conservative red line? What would need to be done to build a proper 8500 RPM 3.6? My MY05 runs out of steam somewhere between 6200 and 6700. I'd like to feel it pull to 7500 then upshift around 8000. Maybe piston speed would be too high? Accelerated cylinder scoring from poor lubrication? Cam chain or tensioner wear?

 

Any flat six builders out there with thoughts?

If you want to shift one of these engines at 8K RPM's, you had better plan on spending a lot of money.  I don't think even Jake takes one of his "all in" big dollar engines that high.

My 2006 S redlines as all other 3.8 997.1 engines (save the X51s) at 7300 rpm.  I have no idea where people get this 7000 rpm redline figure.
