Sheldon, I have used the same dyno shop as have about 20 other porsche owners I know.

In 4th gear as close to 1:1 gear ratio as possible the drive train and tyre power loss was worked out at about 34%. Which is what our club basses power figures for our club championship.

Whatever the true power is our motorsport committee will look at the figures and class you accordingly. I suspect they will put you at around the 220hp.

Oh well I guess it is time to work on the suspension.
