After much debate on the forums, we at MiataSpeed decided to further investigate the differences between the two packages that come standard with the ND Miata.  Mazda lists two different part numbers.   Non-Brembo N251-33-251Brembo NA5F-33-251A All measurements were referenced with the use of a surface plate.However, based on our measurements, we have not found any difference between the two rotors dimensionaly.  The only difference we have found were the internal cooling vanes of each rotor.   Brembo on the left, Non-Brembo on the right. Each rotor is 280mm x 22 mm Offset is the same. Vane design The Non-Brembo has a...

Long awaited results are here! The below results are from our own Custom built tune, not the CARB tune. We should be getting the CARB tune shortly so we will post those results as well! Before we dive in to the results and details, we'd just like to remind everyone that every dyno reads differently. Whether it's a different brand or model and any correction factors on top of that, numbers can be quite different from dyno to dyno. What matters is the gains on the same dyno. Without further ado, the dyno chart! On our dyno, the stock car baselined...

We have a fair bit of experience with the carbon buildup problems of Direct Injection systems in other platforms, we had always been curious if Mazda had come up with any interesting solutions to combat the carbon buildup that happens on the intake valves and intake tract. Excessive carbon buildup can cause poor sealing, hesitation, poor idle, etc.  When we cracked everything open for the Edelbrock E-Force Supercharger Install, we were eager to see what we would find. The answer to our question was...nope. Our shop ND only has 19,000 miles on the clock and we were a bit surprised at what we found....
