Just quit banging on this CIS thing because the CIS is not providing the performance.
I have never claimed CIS provided any performance enhancements. To imply I have is silly. I have stated many times that CIS isn't as bad as many would like you to believe for a street car. I have also tried to show a reasonable option to a 3.6 transplant for SC owners.

There seems to be a lot of interest in telling us the limits of CIS.

What you missed in your "90% calculations" is have more torque low in the rev range with big bore CIS than the 3.2 does. Far away from the 5.7% gains would indicate. More like 15+% once you are below 3500. That makes a huge difference in daily drivability, and lauch, CIS limits and all. The dyno pretty much spells that out as well.

Be happy to post the numbers on a PMO 3.2 short stroke as well so you can point out the limitations of CIS there too
Not much of a limitation short of serious track time from what I have seen so far.

Goran the numbers are @ the wheels.
The 3.2 has Motec management and a complete 993 Varioram induction installed.
