Good Afternoon,
Now that I have your attention those numbers are real but not corrected. I am posting both graphs so you can see Uncorrected and Corrected. These were also run on 93 octane fuel. I am very happy with the results. Car is running strong.
Waiting on cams now. HEHEHEHEHE!!

Very impressive numbers! Very close to Hooleyboy's numbers. Take it to a Dyno Dynamics dyno and see what the difference is. Bigger than usual difference between corrected and uncorrected numbers due to the 49 F and 38 H I guess.

I was impressed when I saw your 519rwhp figure, very impressed...then I read that you have headwork...Ilm just sayin
Jim,
The heads are stock M156 with stock valves. The heads are hand ported and gained about 15-20rwhp. We were testing them for the cams. Thanks.

There are two types of correction.
Bring RATED power up to a standard of comparison for engines at altitude or under less than ideal conditions.
Bring ACTUAL power down to compare with other engines in other conditions.
Bottom line... ACTUAL is a REAL number and is what the engine produced that day under those conditions. You can't race an uprated figure but you can sure run the actual power produced.
Also goes to show there is a fair range available on these engines and demonstrates that the feel we get on days when our cars feel stronger than normal (or weaker) is a legitimate number.
