We are producing the hidden horse power you've been looking for

 


G3 Power Curve Reed Valve:

The proper racing reed cage should have as much airflow as possible, because more air flow means more go!!! Reed cages should have long narrow easy opening petals and high air speed. Reed cages should not have inserts, boosters or stuffers as they cut the air speed and kill the total air flow. Reed cages should not have wings, bars or airfoils inside the cage itself. This makes the airflow travel a longer distance that slows the speed, and thus causes a severe restriction to the movement of air. The only function of the reed cage is to deliver the largest amount of air at the highest speed possible. Always remember that!! Do not believe the big fancy ads that say airflow isn't important, remember MORE FLOW = MORE GO!

 

With all racing engines, the more air you can flow into the cylinder at a high velocity, the more power can be obtained. Below are measurements of different reed valve assemblies measured at 10" of pressure drop, with all figures corrected for temperature and humidity. Note that CFM is cubic feet of air per minute. New designs have increased our performance with New updated CFM Results available soon.

 

For those of you who don't recall that "exhilaration", here is an example of comparative Flow Bench testing for a 250cc;

G3 Power Gurve Reed Assembly 71.40 CFM
Boysen Rad Valve 250cc 64.68 CFM
Honda CR/TRX/ATC25OR 6-petal 54.60 CFM
FMF 250cc & Suzuki RM250 1987-89 6-petal 53.26 CFM
V-Force 53.00 CFM*
Pyramid 51.00 CFM*
Yamaha YZ250 1989 6 petal 50.40 CFM

(All tests were performed in house and *calculated at 10 inches of water pressure and room ambient temperatures, to best simulate atmospheric conditions).


Why should I use the G3 Power Curve 8-Petal Reed Cage? How will it improve my engine?

These are viable questions that need to be answered with facts and not just false advertising copy. First, the G3 8-PETAL REED CAGE will improve the engine power throughout the entire RPM range, because it flows more air at any given RPM than the stock or any of the other after market reeds. This means better low-end power out of turns or hole shot, more mid and top-end speed for the straightaway. Secondly, the G3 REED CAGE will make the engine easier to start, idle smoother, and in general will make the engine easier to tune. This is do to the higher air velocity (speed) and added airflow provided by the design of the reed cage.

Well the PROOF is in the results:

Often when modifying ATV's, the first thing the owner thinks about is 'make it faster'. We don't think we'd get much opposition in saying that engine modifications are the most popular mods done to ATV's today. However, how much are we willing to spend in keeping up with the TOP of the PACK and where do you Start?

We have performed numerous "at the Dunes/Drags" Field Replacements with many Racers/Riders who want to try our G3 Power Systems (SCT Intakes, Power Curve Reed Valves and 12mm Torque Spacers). MOST of these Racers/Riders don't want to spend $5,000 let alone $15,000, however we get their Attention when offering our G3 Power Curve Reed Valve, 12mm Torque Spacer & Swirled Charged Intake for under $250.00 while delivering "Mind Blowing Results".

We feel the Root to all Horse Power is derived principally from your Intake and Reed Gage and most arguably the first place to start Performance Upgrades.


What We Deliver:

Our Power Curve Reed Valve:

· More Air Flow, 2 Strokes need to move a lot of air through the reed valve quickly. The easiest way to get the most air soonest is to have more petal area openings at every tip of the reedcage and it's proven with our sloped power groove technology. Most other reed cage designs incorporate only a 2-4 Petal design, Ours Turn on the Power with 8 Petals.· More Air Velocity, so that there is higher air flow as soon as the reed petals open (lower reed petal lifts). Since the majority of the action in our reed cage is at or starts at the tip that's were we focus our designs. · Adjustable Power, Our reed valve also comes with tension adjusting reed stops, allowing you the versatility to "dial in" the desired power. Delivering more airflow at lower reed petal lifts offers · Fantastic Throttle response· Quicker acceleration out of the hole· Hard Top End Pull · More Horsepower and Ultimately ·More GO!

Our 12mm Torque Spacers:

· More Torque, Our 12mm reed spacers manipulate intake air so you can adjust how hard the engine kicks when you slam on the gas. ·More RPM, Case Volume & Velocity, Our Torque Spacers help smooth and improve air flow into the cylinder. Moving the reed cage further back slightly shifts power toward the bottom end resulting in sharper, quicker throttle response, increased torque and added horsepower. ·More Air Velocity, Using Our Reed spacers will improve the velocity of air/fuel mixture entering the cylinder increasing low end & mid-range pulling power with overall great performance gains.
