Today’s topic is fuel delivery – what to do and what not to do to keep fuel systems completely dialed in and up to snuff, especially at high horsepower.

All aftermarket parts are not created equal. Sure, a set of rims can turn a plain Jane daily driver into a head turner, but when it comes to true performance, superior quality materials and engineering are where the rubber really meets the road.

In this episode, Kevin and Willie nerd out over both in conversations with Forgeline’s David Schardt and ODYSSEY Battery’s Alan Kohler.
