I've seen many postings of dyno results on threads on dyno results. I'm curious that my results conflict with many that I've seen here. What I've seen are results in the 195 bph range.

I had my totally stock S2K dyno'd about four months after I received it with about 5K miles on it. The only difference was a change to Mobile 1 Synthetic Oil - which obviously wouldn't make a difference in the world. Here were my results:

75.8 degrees
Measured:
Max Power = 205.5
Max Torque = 138.3
Corrected:
Max Power = 201.7
Max Torque = 136.5

Any ideas or am I reading the results incorrectly?

If my reading is in question, I'll be happy to scan the data and post for someone to correct my reading.

 

I dont really see anything wrong there, I think Mobile 1 is one of the few synthetics to actually show a gain in HP because of it being easier to pump.

 

Sounds about right. On two different dynos on two different days, my car has registered 204 and 196.

 

it's all about how much the ECU is retarding you because of heat soak and other factors.

 

Dyno variations, operater variations, fuel variations, weather variations, etc. Up to 5% could easily be something other than the engine tune, so it is very important to control test conditions as closely as possible. A few HP one way or another is really pretty meaningless.
