SharkWerks 2010 997GT3 On Ze Dyno Hey fellas, we're still working on the video for this but a while back we spent some time with Todd@EVOMS tuning our 2010 997GT3 and in the meantime here's a few shots
On the way to the dyno... we brought Kermit along for some "extra-curricular activities":
Strapped on and ready to go:
Running along..
Checking some scores...
With interest...
We made around 60+ pulls throughout the day with various configurations, and Todd made adjustments to the EVOMSit software throughout the day. We also used this time to dyno our upcoming SharkWerks 997 GT3 Track Exhaust system.
Here are the results. The top line is what the car put down with the Track exhaust and the EVOMSit software. The bottom line is the baseline.
We were most interested in the delta, or difference after the fine tuning and exhaust swap, to see what changes were made to the car's power curve as Todd continued to tinker with the ECU.
Here's another graph, showing the result with software alone as well (in middle position):
The tuning involves a more aggressive fuel map, timing advance optimization for specific grades of fuel, and a more responsive accelerator pedal.
A summary:
With software only, the 2010 GT3 went from 392 RWHP to 404 RWHP at the peak. The car gained about this much horsepower for most of its RPM range.
The car gained over 10 ft-lb of torque at its peak around 6600 RPM and more torque throughout the RPM range.
With the exhaust and software, the gains were higher, bringing it up to 414 RWHP at the peak (22 RWHP net gain), more torque at the peak, and a large gain in torque between 3700 and 5400 RPMs.

There is more about the EVOMSit software tuning process here, and a video coming soon.
Before leaving the track (Sears Point) had to get some good gas to go

Great stuff, Alex... That's a pretty impressive improvement with the exhaust and software on an NA engine that's already well-tuned. Damn, I need to get a GT3. Thanks for sharing!!

Actually, we did meet at the dinner at Cibo's... You were a little frazzled, so I'll forgive you.
