As with most advances with performance in our cars, it's usually one pioneer who thinks outside the box and does the homework for the rest of us. Kevin is a prime example of this with his plenum design, people are seeing what can be done and are making their own versions, even Dalke has took notice. Casey just went crazy with his setup but he too has opened up everyones eyes/minds with cam specs and head combinations. Everyone already knows what Dalke has done which is amazing. I don't have the knowledge or skills to do what they've done so I'm definitely one of the many that benefit from their experimentation in performance upgrades. Not to mention that they're not secretive with their work and inform everyone so that we as a club can improve our cars, to that I say thanks.
