ok now who is interested ??

Cylinder Head Porting Defined

Porting is basically opening up, re-configuring and re-surfacing the ports of a cylinder head. Why port a cylinder head? The simple answer is to let the engine breath easier and more efficiently and therefore produce more power.

 

Cylinder head ports fall into two basic designs; the Straight Shot port and the High Approach port. In a Straight Shot port, the design allows for a line of sight from the inlet directly to the front opening of the intake valve. Sometimes this design gives a lower flow value but because it is straight, we attain higher velocity of fuel/air entering chamber. It also creates a turbulent spin or swirling in the combustion chamber, yielding a more efficient and more complete burn.

 

A High Approach port is where a turn is necessary in the port design. The term "high approach" comes from angle of the last section of the port relative to the valve - it is more in-line with the valve stem.

 

We take advantage of this to get a full volume flow path in the complete 360° circumference of the valve. Making a turn to an airflow is problematic but we caress the turn - making it as moderate and efficient as possible - to use it in our favor. The straight shot into the opening yields a fuller, more uniform flow around the entire valve curtain. The advantage is that the complete valve opening is used more completely.

Muzzy Street Megaphone Exhaust Systems

The new Muzzy Street Megaphone systems give that pro drag race look without the right hand cornering reduction typical of Sidewinder systems. Engineered and hand crafted in stainless steel entirely by Muzzys to Rob Muzzy's own exacting standards. No other megaphone system on the market offers this level of quality and performance.

Built with a removeable baffle, this system produces the legendary Muzzy tone and a street rideable sound level. For competition use, remove the baffle for open megaphone drag racing thunder!

The Muzzy Street Megaphone comes in two varieties. A Full Stainless System with header, mid. and megaphone muffler and a Conversion Kit (mid. & megaphone muffler only) for those who already own a Muzzy Stainless Exhaust.

Must have some cost savings mah, if not bring in my own very xiong. The looks department may not be that appealing. Unique, power and noise is the selling point thou.
