NMCA Edelbrock Xtreme Street/Ultra Street competitor Ron Belcher and 2016 NMCA Holley EFI Real Street champion Camren Massengale, two heavy-hitting team RPM Transmissions racers, headed over to Muncie Dragway in Indiana on Thursday, October 11, in preparation for Donald “Duck” Long’s upcoming No Mercy mega race at South Georgia Motorsports Park and the results were… interesting.
While we can’t share the specifics on numbers or what exactly went down with Belcher’s C6 Corvette or Camren’s LS-powered ’01 Z06 Corvette, we can let it slip that Belcher’s currently in the process of making a big change in the boost department.
Formerly a nitrous guy, Belcher swapped to a supercharged setup in 2017 and ran a Vortech unit all throughout his 2018 and 2019 seasons. “We couldn’t ask for more power than what the Vortech delivers and can’t say anything bad about them a tall – it’s been great for our program – but I think we’re running out of volume in the hot weather,” stated Belcher, who plans to try his luck with a ProCharger F-1A-91 blower at SGMP instead.
With as much money as he’s got invested in his build – which includes an alcohol-chugging 400 ci All Pro-headed LSX block filled with a Winberg crank and aluminum rods – Belcher owes it to himself to test out all his available options. “We have not cut a single corner on this build,” confirmed the Kentucky-based racer, who relies on the expertise and guidance of his engine builder, fabricator, Holley EFI tuner, and crew chief, Kenny Johnson of RPM Transmissions, to steer him in the right direction.
Of course, Belcher also relies on an RPM-built Powerglide transmission to get down the track, and so far has run a personal best of 4.76 at 148 mph with the Vortech on board. “We also run an RPM 9” rear conversion, and we put the transmission in maybe five years ago – it’s been absolutely bullet proof ever since,” said Belcher. “Without Rodney [Massengale of RPM Transmissions] and Kenny [Johnson], our program would be way behind.”
The testing in Muncie went well for Belcher, who spent some time making rear end changes and adjustments to the independent rear suspension to try and get his 60-foot numbers down. “We’re going in the right direction for sure and saw a big improvement from the last time we went out. We’re gonna have something for ‘em next week for sure!” he stated of his plans to run in the Ultra Street category at No Mercy and earn some more glory for Massengale and the RPM Transmissions team.
