As part of a dyno-day organized by Danno on Rennlist, I had my car dynoed by DSR in San Jose, CA.
I was pleasantly surprised to see that my 944 S2 appears to be a unusually “strong” example. It achieved the following numbers (averaged over 4-runs) on the day:
| 
 | Power (bhp) | Torque (lb-ft) | 
| Rear Wheel Numbers (SAE corrected, average of 4-runs) | 187 | 181 | 
| Estimated Flywheel Numbers (assuming 15% drivetrain loss) | 220 | 214 | 
| Porsche's Specification for 1991 US Model 944 S2 | 208 | 207 | 
The following are the dyno graphs for my car on the day (for reference, you can see other 944 S2 dyno results by clicking here):
