Sly, It's hard to tell if your motor was modified without actually opening it up. Most experienced owners would be able to tell by just driving it hard especially on the track. Perhaps you could locate such a Porschephile at a track meet and ask them to take your ride out for a spin. By the way what's a 911 cp ? Never seen this designation before.

A few minutes on a dyno will provide you with HP and Torque curves that will reveal whether your engine is stock or upgraded. Might even show how well it's tuned. Much better info than someones "butt dyno".

Sylvester, there are lots of pelicans in the Houston area. Keep your eye on this board and the local board for our next get together.
Actually we are about due... maybe this is a good excuse for our next one!!

The SC stock, is rated at 180HP....engine number will tell you what it started out as. 930/04 for US 49 states, 930/06 for CA.
Number is fainter than the serial number and located near the oil sender to the right of the crank pulley.
