Diesel Performance Podcast

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!

We've now utilized 6.7L Cummins engine; LBZ, L5P, and 3.0L Duramax engines, and soon a Powerstroke 6.7L engine. If you like data or carnage, you will love this episode!

You have to see Patrick Brown's Cummins he is bringing to his first run at the UCC event. Chris sat down and talked with him about what he expects to see it do. Patrick is no stranger to competitions with having his eyes one time set on the Diesel Power Challenge nd having competed at King Of The Streets, he's ready to throw down at the UCC. Humble, determined, and doing wild things with such a cool Cummins, we are stoked to see what Patrick accomplishes this weekend!

One of the show's favorites is back, Robby Garcia joins Chris to discuss what he expects of his truck at this years UCC! This will be his 4th time competiting, a seasoned vet, and continually improving his results; these factors position Robby to finish quite high this year. One thing we know will happen, Robby will have a blast and bring that vibe to the whole field. Good luck, Robby!

Cody Hawk sits down with Chris on this episode! We get the scoop on the new competitor, from his roots with 7.3s to his preferred Duramax platform. He breaks down what he wants to see out of his truck at his first event. The man is in hustle mode and it's hard not to admire the drive and work ethic. Last year two spots on the podium were grabbed by rookies, will Cody continue the trend? We hope so, good luck Cody!
