Pro Mod Sound Testing at Fontana

With the newly constructed sound wall in place, it is time to find out how well it actually works. NMCA WEST recently posted the following:

"The results of yesterday’s sound level testing at Auto Club Dragway in Fontana indicated that Blown Roots combinations with Zoomie Headers are over the track’s decibel level limit for 2014.

 

Therefore, the Blown Roots combinations with their current exhaust configuration will not be able to run in NMCA WEST Pro Mod Competition at the three Fontana events. They will be able to compete without any issues at both Pomona and Las Vegas.

 

“The Pro Mod Class will still be contested at the three Fontana events with Turbo, Naturally Aspirated, Nitrous, and Centrifugal Supercharger combinations,” said Rollie Miller, National Event Director at NMCA WEST.

 

Miller added, “If Blown Roots Blower combinations can modify their exhaust and come in under the 85db limit, they may compete at Fontana in NMCA WEST Pro Mod. John Scialpi is currently working on several header and exhaust baffle/muffler combinations with Flowmaster and will attempt a sound test in coming weeks to see if any of his combinations will adhere to the decibel limit.”

 

Roots blown Pro Mods may still have a chance. Weeks later, Flomaster steps up with new mufflers.

With the help of Ronnie Olson and the entire staff at Flowmaster, John Scialpi's blown Pro Mod has passed the stringent sound test at Auto Club Dragway in Fontana.

 

Any other Pro Mod competitors with roots-type blown combinations can contact Ronnie Olson at Flowmaster by calling (707) 540-9448 or sending an email to Ronnie.Olson@flowmastermufflers.com."
