R&R heads are simply the best!
Keeping up with the Ronzellos is not for sissies! This family is
nuclear powered! In a mere 5 years what began as a father-son hobby
of souping up Jr.s’ Sporty, has evolved from Dynos in the garage and
a machine shop in the basement, into a large, bustling business (R&R
Cycle) with CNC milling stations cranking out 300+ cylinder heads a
month! Reggie Sr. is recognized by performance industry leaders as a
top expert in engine performance theory specializing in port flow.
With 100’s of hours studying (and re-writing computer programs and
code), 100’s of hours flowbench testing, over 3,000 dyno runs, Reggie
knows his shit! Period! Every R&R head he produces is CNC ported to
meet the specific requirements for a particular application utilizing
Reggie’s proprietary Cross Sectional Flow Analysis. So every R&R head
has THE perfect match of port volume and shape to meet THE specific
appetite of the engine it will feed. The result is unparalleled
volumetric efficiency (MAJOR torque AND throttle response)= an engine
that pulls hard and loves to rev! R&R heads are simply the best! One
small but amazing benefit is that your bike with R&R heads and
reasonably close jetting and timing, will require absolutely NO choke
to start and idle smoothly when stone cold. During a recent visit
with Reggie, this writer witnessed this demonstrated with several R&R
equipped bikes. Amazing! Reggie explains that the reason that most
engines require an overly rich mixture (choke on) is due to lousy
port design/performance! Anyone who has ever struggled with firing up
a cold-blooded bike can relate! So not only do you get more power out
of your ride, but it will be less temperamental and easier to start!
Very cool! |
