Since the rev limiter can be set for every gear on a manual, the system could be programed to limit rev's at 5470 in 6th thereby limiting the car to 150-155 range. Which is where everybody seems to agree it tends to fall.
6,000 RPM as posted in whatever that "factual" document is would put top speed at 164 MPH (262 KPH) which we know is not the factory limit.
I stand by my numbers. 5470 RPMs was likely the rev limit on my car when it first went on the dyno. Just like Jake told me.Since my rev limiter is now set at 6300 RPM in 6th gear my theoretical top speed would be 172.76 MPH (272 KPH). Assuming the HP and the torque can get it there over wind resistance.I know last week I was bumping 160 on the speedo. Car wasn't even panting.Just sayin'roadster with stick
