Diesel Performance Podcast

We got a bonus episode! Anthony Bruneni and Chris Ehmke are joined by Charlie Fish of KC Turbos. He called in to discuss a new diesel class he created for this weekend February 26-28th, The Average Joe Blue Collar 2WD No Prep Diesel Truck Class. Why did he create this race? The spirit of racing isn't how much money you throw at a truck, it's about the passion. Charlie breaks down the rules, what drivers and spectators can expect, and what this class means to the diesel industry. Oh, we forgot to mention that $20k goes to the winner!

Anthony Bruneni and Chris Ehmke are joined by Lavon Miller to discuss what he's been up to, but really they had to get the scoop on what's up with the Seventy2fast race going on this year down in Indy during UCC weekend. The amount of interesting aspects and the amount of money that is on the table for the competitors is mind boggling. The Seventy2fast has $500 callouts, where racers can target a specific driver to beat after putting down their money and the target matching, winner of a head-to-head race takes the money. Contigencies for Powerstroke and Duramax, Powerstrokes can win an extra $11k if they take home 1st place and Duramax drivers can earn an extra grand per round if they beat a Cummins or Powerstroke and an extra $3,000 to a winner racing a Duramax. $70k goes to the winner! Lavon walks us through everything about this race and we have to be honest, we haven't been this excited for an event in a while. Check out the event by visiting www.seventy2fast.com or following Lavon Miller's social media channels. Take a listen!
