Testimonials

 

R2C filters are working great! Our motors have been spotless when we have tore them down for a rebuild. We told our engine builder we have been using the R2C filters and he was going to start recommending them to everyone. The greatest asset of the R2C filter is just being able to blow them out and stick them right back on the car. No filter oil and no waiting for them to dry on race day.
I won a couple features this year in my rookie year with the late model.
 I also have won a few big mod races last year and this year. I won the UMP Nationals last year and won the Big Dawg 100 this year with the modified. Thanks R2C!

Asphalt Racers..............Bolt on immediate Dyno-proven double digit gains!

 

R2C's computer designed CFD 4150 Air Cleaner Bases and new Black Hex Series race filters provide double digit gains in horsepower and torque for Asphalt racing engines.

 

*New Black Hex Race Series Filters

  • Maximum Dyno Proven Horsepower and Torque Gains
  • Improved Booster Signal for Better Throttle Response
  • Faster Lap Times
  • Simple Maintenance and Long Life

      The Most Powerful Base/filter Combination in the World!

Months of design evaluation and flow bench testing, followed by extensive dyno and track tests (now over 1100 independent pulls!) conducted by the most respected names in race engine and carburetor assembly, have resulted in the best flowing, highest power producing air cleaner bases for Holley 4 barrel race applications. Every application from Stock Cars to unlimited Late Models and Big Block Modifieds have achieved significant gains in power and response/driveability.

R2C engineers developed each precision base shape to augment the venturi profile of the popular 4150 series Holley carburetor, resulting in dramatically smoother entry profiles and reduced restriction and a much stronger and consistent venturi/booster signal, allowing precision racing carburetors to perform at optimum levels and engines to produce increased power and torque. When used in conjuction with R2C Aspahlt Modified air filter configurations, nothing comes close to the performance advantage R2C CFD 4150 4 barrel bases offer pavement Modified racers.

CFD 4150 4 barrel air cleaner bases are offered in three configurations, allowing racers to select the precision contour that maximizes overall performance based on their individual applications.
