EVOMSit Software for 2010 997 GT3, dyno graphs and video inside
Hey guys,
Todd Zuccone from Evolution Motorsports was visiting our shop this week, so we decided it was a good time to dyno test and tune our 2010 GT3 project car.
We drove the car to Stasis Engineering (an Audi Tuner, located at Infineon Raceway) and reserved the dyno for the whole day. I'll tell you now, there's nothing quite like sitting in a room for 8 hours while a GT3 motor is taken to 8500 RPMs.
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.
Note that Stasis' dyno accounts for a very small drivetrain loss when run in AWD mode (and the Porsche running RWD in this case). 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.
You will notice a drop in torque at lower RPMs (below 3500) with the Track exhaust due to the greatly reduced back pressure, but there is a significant increase in torque after this point and horsepower throughout the RPM range. We still recommend our Street Bypass setup for most owners for several reasons, including that it does not lose torque like this (and it doesn't set off car alarms, cause your dog to run away, etc.).
I will be out of town for a couple weeks, but please PM Alex (Sharkster) or email alex@sharkwerks.com for pricing on this product. It is available now (product page).
Thanks,
-Dan
PS - Our street exhaust (SharkWerks GT3 Bypass) adds less power (5 RWHP) than the Track version, but does not lose torque below 3500 RPMs.

Outstanding.
Waiting for FVD to make me the race headers (M&M) from Germany.
When all's here, we begin.
Juan
Hey Juan, we're ready for ya.. Remember the motor is tuned for the back pressure of those factory headers (VERY GOOD ones too) and cats. After that is all fine but I've seen cars loose some etc....
