Philip Delaney - Rage Wraps

I have had the fortunate opportunity of working with Rich Groh of RGR Engines for almost 4 years. Within that short amount of time, our racing program has progressed substantially. Thanks to Rich, not only did I go from #8 in 2007 to #2 in 2008, but I also won the 2008 BFGoodrich Factory Stock Shootout. Rich is always researching for innovative ideas to give his customers that extra edge they need to beat out the competition. He is an engine builder above the rest! Not only does he build the fastest engines on the market, he also assists his customers at the track when they need him most. I owe my racing success to Rich and will continue to support his cutting edge ideas. Thanks Rich! - John Leslie Jr. NMRA Factory Stock

Bruce Hemminger - NMRA Real Street Champion and Record Holder 2008

Rich Groh is the baddest engine builder on the planet. I was the ET and MPH record holder for the 2008 Pure Street season and its all thanks to Rich. I honestly owe my entire racing career to Rich Groh. RGR Engines builds the baddest most effecient engines any single racer could ask for. Rich, Thank you for everything you have ever done for me and my racing program.

I feel Rich @ RGR Engines builds the most powerful and innovative engines on the planet. He built my 2 time Factory Stock World Championship engine which also posted the quickest ET in Class history an 11.07. This same engine posted 10.96 @ 122mph on BFG's at a non sanctioned event. Even more improbably is the fact is sports Unported E7 factory casting heads Rich did his magical valve job on. I can't say anything more about his work other than the Records and Championships speak for themselves.
