Gas Flowing

[BRUN]

what exactly is this ?

 

[ChrisB]

Working on a channel/port/tube whatever removing machining burrs, smoothing tight/poor flowing bends, matching manifolds to the head etc.

All just to give less restriction to the flow of gas in and out of the engine.

gas flowing as Chris says is the fun part of engine work. Cylinder head development is where you can make all the power as its the haed that makes the power. so long as the fueling and exhaust systems arent goint o restrict it in any way.

the more air you can flow through changing of port sizes and shapes, the more fuel you can burn.

not easy to get perfect but the most rewarding.
