  • Weight and consistency drives RHM in a new direction 

  • Trades the 94mm turbos for a new NHRA legal centrifugal ProCharger

  • Bolts on a new Magnatron manifold to the existing 548 ci PLR engine. ​​​​​​​​​​​​​​​​​

The Ronnie Hobbs Motorsport (RHM) brains trust has been busy putting together a new combination to compete with the 'best of the best' Mid West Pro Mods at Keith Haney's MWPM series.

In a recent article by racepagesdigital.com and published by procharger.com, Ronnie explained "I had a talk with Steve (Petty), Jamie (Miller) and Eric (Dillard) and they're telling me there's no easier way than ProCharger".  

Although the 2017 Shelby Mustang 350GT is a record-setting car and has run 3.50s in the past, setting the RvW record with a 3.57 ET, and PDRA Pro Boost Speed with a 218mph, the RHM team has had their work cut out for them to run these times again, attributing the weight rules of the classes as the main issue.  

"Daniel [Pharris] was already headed down this road before I bought the car [from him], he had two motors and a spare front end for the ProCharger, which I purchased,” explained Hobbs. “I think it’s clear that, regardless of what promoters say, the turbos are difficult to tune and difficult to be consistent.”

Pro Line Racing has developed the ProCharger program with great results over the last few years and more teams have converted to this combination, "Although the weather will be hot, I am so excited to put this new configuration on track this week, having Petty and Miller working to lay down some fast passes and for me to feel the difference compared to the turbos!".

The pinnacle of the week will be this weekend's race at xtremeracewaypark.com and we can't wait to get back out there!​​​​​​​​​​​​​​​​​​
