To make power in your normally aspirated engine, you need
the air moving through the engine, to have VELOCITY. Especially in the
intake tract. Volumetric efficiency = Flow x Velocity of the air. Volumetric
efficiency = The amount of air that becomes captured in your cylinder
for combustion. Volumetric efficiency is directly related to TORQUE. Torque
is what you care about. Horsepower comes from torque. What we do to "reshape"
the intake tract, involves the adding of material and then redesigning
it to increase the velocity of air into the engine up to 30%..
No one else offers this to the public. It is left for the top teams from
top engine builders, but not neccesarily in motorcycles. The same cylinder
head design that we used to set the land speed record on the CRF 450R
with 63 HP, and make over 40 HP on the 08 YZ250 F being built for Malcolm
Smith, we offer to you, on all modern four strokes. |

| After the intake tract, we fix the combustion chamber. The incoming air still needs to get past the intake valves and distribute in the cylinder in the right areas. If not, they spill out into the exhaust pipe during valve overlap. Then, with a properly designed combustion chamber, the fuel and air, burns more complete, ensuring the highest power. And last, but not least, is some reshaping on the exhaust. Although, the final shape may not look optimal, it is. You need to have a shape that not only evacuates the exhaust quickly, but also keeps "dirty" exhaust from returning into the combustion chamber where it can retard the power made on the next combustion cycle. If all this sounds overwhelming, don't worry about it. It's not your job. Your job is to remove your cylinder head and send it in so you can have more instant power from bottom to top than you ever thought. |
