My initial thoughts were to use a Garrett GTX3071R for its broad PR range and space saving size. I'm most certainly hoping to get our awesome fabricators the go ahead to design a kit that would be best suited for the car. In this case, the first step is tuning, the second step is a FMIC with supporting mods, and the final step in the stock turbo configuration would be to finish it out with the downpipe. We have done the research and fought with the car to tell us what it wants, which translates into a straightforward modification path for our customers. This would be reserved for Stage4 at this point. Your results may vary depending on octane available and dyno configuration.Ĭlick to expand. Here are our current packages and a representation of their power as measured on our dyno. This means the engine will be happy to give you power as you rip through the gears, and continue to give that power with less cool down time. We were awarded with more consistent power from pull to pull, as well as a larger gap from the knock threshold. The car was much "happier" with the loss of back pressure and additional exhaust flow.
That's not to say the downpipe doesn't play a supporting role in all of this. We also engineered an excellent replacement for the downpipe, but found that it wasn't going to continue to give these massive gains as the turbo was simply done flowing usable air. We already knew the FMIC was the biggest restriction on this car and made some massive gains by engineering a phenomenal replacement. I ended the day with a better understanding of just how much different this platform is from anything else we've supported in the past. It further goes to show how the typical cookie cutter "Stage" theories just don't work for this car. While it wasn't an earth shattering amount of power, it ended up complimenting the overall curve. I even went as high as 25psi to see what might have been available, nothing! (Don't try that at home) Eventually, I ended up with a mix and match of what worked well out of all of the changes. Some of these netted results, but it was nothing spectacular. I tried boost down low, boost up high, more timing, less timing, more fuel, less fuel, more VCT, less VCT. I went through everything in the arsenal to try and produce the big gains we all want. The car simply wasn't responding as I had hoped.

What happened over the next few hours was a bit of confusion, and a lot of trial and error. Shortly after I was back on the dyno ready to make power! We pulled the car off the dyno and back into the shop for a quick replacement of the coupler and clamps (Thanks Evan & Billy!). Sure enough, on the next dyno pull one of the charge pipes blew off and negated all of the previous results. Power was a bit under that of Stage2 and everything seemed to be working a bit harder than it needed. Within the first few dyno pulls I had a feeling something wasn't quite right. I setup the car with our Stage2 map to get a baseline with the newly added downpipe.
I began the day with high hopes of making bajillions of horsepowers with the Stage3 configuration. So today was a bit of good and bad, and a bit more of a learning experience for this car.
