On the Dyno
As we stated in the text of this article, we performed several dyno pulls comparing the PurePower filter to a standard oil filter but didn't see conclusive proof that the filter made horsepower. Still, we thought we'd show you a comparison of two pulls where the oil and coolant temps were the closest so that you can draw your own conclusions. Still, if the PurePower can help a race team save money while also improving its ability to monitor the engine's health, we think it's probably a good investment.
