Our idle warmup provided a nice baseline test to evaluate the benefit of the stock liquid-to-liquid oil cooler. From what we saw in the conditions of our first test, warmup is not greatly affected by this component. In this second portion of product testing, we will be evaluating the impact of this heat exchanger on cooling performance. More importantly, we will be evaluating the cooling benefits of our liquid-to-air cooler.

We also hinted at the use of shrouding to direct airflow properly through our cooler. Optimal airflow through a heat exchanger is vital to the efficiency derived from an oil cooler system. In addition, we see value in retaining the stock engine undertray, which aids in … Continue Reading ››

The Mazda Miata MX-5 is the most-raced production vehicle in the world. It’s a great top-down cruiser, features low entry-level pricing, and it’s inexpensive to modify and repair. Fuel mileage is fantastic. Saying the Miata is the end-all and be-all vehicle would be a stretch (it has its limitations), but it is one hell of a car and an amazing bang-for-your buck regardless of use.
