Kevin and Willie are joined by Glenn Rains of Rains Precision Motorsports (RPM) to discuss the reality of four-figure horsepower. Glenn breaks down the brutal realities, headaches, and triumphs of running a 10-employee, full-service modern muscle shop. He talks about doubling factory Hellcat numbers, the critical nature of EFI tuning, and why he gives customers an honest talk about "informed consent" when pushing stock internals to the absolute edge for their builds.
