“Intake, test pipe, and a tune ONLY” was my mantra. I’d just bought a shiny new ’13 tech package VRM MazdaSpeed3 with the extended warranty, 3 miles on the odometer as it rolled off the lot for the test drive. Via the web forums (back when MSF was still popular), I had performed my due diligence in terms of where I was headed with this ride. I knew what my mods would be, the results to expect, and even learned a bit about the tuning process, all with the intent to “stock out” in less than an hour in the event I broke something on the car.
But… the local Nator chapter wrapped their slithering hentai tentacles around me, and those thoughts of a mildly tuned car with the manners fully intact started to erode. The friends, the fun, and the performance results were an instant addiction.
In just a few short months I had sold that warranty back and started down the rabbit hole. Trips to Epic NATOR Meets were a terribly awesome influence, seeing cars on the bleeding edge of the DISI Mazdaspeed platform, and meeting several of the prominent people in the Mazda community that were so forthcoming with their knowledge. The hook was set!
I found myself pursuing information, and if there wasn’t any data to be had, I wanted to make it myself. I tested and cataloged a variety of items, from NVH with motor mounts to compression test compendiums (yes Cylinder 3, you deserve that BAD rap!), meanwhile moving along the mod path to a medium turbo, front mount intercooler, and a methanol kit. Once I purchased a spare long block, I knew I was getting in ball-joints deep.
Fast forward to today. I’ve been very fortunate to be chosen to test products for a handful of vendors! With an aligned focus – direct fit or minimal fabrication parts – I’ve reached my (probably temporary) goal of 500 wheel horsepower! Where I’ve tested the limits of products/parts for many companies – whether they have asked me to or not. The CorkSport 3.5 Bar Map Sensor is a solid example of exceeding the envelope, as I did manage to over boost while playing with my EBCS configuration, and pegging it at 37.58 PSI. (At 900 ft. ASL)
Corksport asked me to describe my modification journey and how their beta parts have impacted my build and decisions, so there is no slight intended to the multitude of other people involved in my project – that list is not short.
I’ve run the Corksport intake manifold for nearly 2 years and just prior to the big turbo transition.
- It gained 12 g/s flow on the identical tune and no other modifications, so I knew it was an immediate upgrade.
- I’ve been hammering 30+psi through it for the majority of that time, and my built engine is approaching 25 thousand miles with that duress.
- The spark plugs have been pristine and uniform, indicating to me the flow is balanced in the runners.
- There is no better fitting upgrade intake manifold for the platform.
