Staged Dyno Results for 2010 MazdaSpeed3

We have received a lot of questions regarding the dyno numbers for our products for the 2010 Speed3. So far we’ve only released a Stock vs. (Intake+RacePipe) dyno sheet, and I figured it was time to add some clarity to the questions and comments in a centralized location instead of replying on specific forums and leaving other people in the dark. In the end, our Intake + Racepipe + Downpipe give customers the ability to crank out 51 more horsepower for $687. The key to getting the most out of your car isn’t just to make ample power increases, but to have money left in your wallet to add more options sooner. CorkSport has you covered at a cost of $13.74/hp with a peak gain of 51 Wheel Horsepower and 47 Ft Lb of Torque.

The 2010 Speed3 has a lot of power left on the table, and our product development has really brought that to light. Unfortunately, we stage build everything -starting with an Intake, adding a RacePipe, then the DownPipe…and Dyno and labor hours add cost to parts, so we try our best to get the data we need to validate our products without adding a lot of cost to the parts based on a variety of test iterations and combinations. This blog post details the results of the staged build on our 2010 Speed3. In addition, it makes some details clear about comparing our systems to other options on the market -what’s included in intake and downpipe packages to provide detail to costs vs. gains.

Stock vs. Power Series Intake System
Our $239 intake system includes our aluminum turbo inlet pipe, billet MAF housing and CorkSport Dry Flow Air Filter. Again, this package includes the turbo inlet pipe -it is the only system on the market that is packaged including the inlet pipe -all others are marketed separately. The torque gains were nearly 20ft lbs increase on average. We also saw large sections of torque gain that were up to 33ft lbs of torque. The horsepower gains were equally impressive with the largest differential being a 36whp gain over the stock numbers. Our system works great, we have put a lot of time into the design and validation testing of it and it generates some serious power…at $6.63 per horse at the wheels.

Racepipes and Downpipes…*
The CorkSport TurboBack Exhaust packages are broken into three components: The Downpipe which evacuates exhaust gasses from the turbocharger into the main exhaust system; The Racepipe (available with or without high flow catalytic converter) which replaces the factory secondary restrictive catalytic converter; The CatBack Exhaust System which is comprised of the primary 80mm (3.15″) exhaust pipe and resonators and the dual 80mm tailpipe section. The main component to discuss is the comparison of the CorkSport Downpipe and Racepipe to other Downpipes on the market. A few other Downpipes cost substantially more -due partially to the fact that they include what we sell as a Racepipe. Despite our separate packaging, our pricing is still competitive at $448 for the combined package, and allow our customers to swap in the wide open 80mm Racepipe on track days and retain their factory catalytic converters or choose the Racepipe which features a high flow spun metallic catalytic converter (an additional $200). Whether you choose the Downpipe/Racepipe combination with or without a high flow catalyst, you’ll find our prices aggressively competitive.

Stock vs. Power Series Intake System + Power Series Stock Fitment Racepipe
This stage adds the Power Series RacePipe to the 2010 Speed3 w/ CorkSport Short Ram Intake & Turbo Inlet Pipe. Power goes up nicely to a combined gain of 41whp and 33ft lb of torque at peak and a blistering 50ft lb of torque at 3000rpm. Where the intake alone dropped low end (1600-2900RPM) torque by a few pound feet relative to stock, the addition of the racepipe puts the entire torque curve higher than that of the stock setup. If you’re running a rally car or just want blistering torque -this is your prime combination.

Stock vs. CorkSport Intake + Racepipe + Downpipe
This stage adds the Power Series Downpipe from CorkSport to the 2010 Speed3 w/ Short Ram Intake & Turbo Inlet Pipe. The CorkSport downpipe features a divorced wastegate dump design -providing a separate outlet for wastegate gasses and avoiding disruption of the primary exhaust pathway when the wastegate cracks open to bypass excess exhaust pressure past the turbine wheel. Adding the downpipe to the previously detailed combination of intake and racepipe, power jumps another 10 horse at the cost of a little bit of peak torque, but the low end of the torque curve increases nicely. As a combined package, the CorkSport Intake, Racepipe and Downpipe put down 51 horsepower and 47 pound feet of torque at the wheels. Watch for the release of our downpipe for the 2010 Speed3 in the coming weeks.
