Motor Cars, SUVs, Trucks / Bakkies & Bikes | Petrol & Diesel | The Cylinder head for the Enthusiast | | SAC Engineering's scientific approach to gasflow cylinder heads and porting can be the result of a personalised specific head conversion on your vehicle that really satisfies you. Very little people realise to what extent we go to when we are asked to gasflow a "special head". It is not only about porting and gas flow, in modern multi valve cylinder heads, there are many moving parts - cams, valves, retainers, cotters etc. | | The flow, mass and working resistance all need to be consistent on all the cylinders and then if you keep in mind that the air flows through a port and over a valve on high rpm at roughly 800 km/h then we should understand the importance of the aerodynamic finish inside the port and on the valves. | |
| | The mass of the valve for instance multiplies as the rpm goes up and only a few grams off a valve results in far less energy being used to move it up and down. | A four stroke engine would open and close its valves 2,000 times for every 4,000 revs and how will that effect the power when there are 16 valves that open and close? It is of utmost importance to lighten the valves when in search of extra power. A 6 cylinder 24 valve or a V8 with 4 valves per cylinder are effected more by this philosophy. | | For peace of mind that everything is working in harmony in your cars engine you really need to have the head flowed and for the best result you need to ask for a special one. | | | | | We always need to achieve reliable power. | | The cylinder head has always been a reliable source of power that all successful race teams and manufacturers have utilised to stay in front of the competition, now thanks to advancements in the industry, this technology is available to the man in the street at a competitive price and can be tailored to suit any specific need. | Be it that you are looking for out and out horsepower or merely for improved fuel consumption and reliability, SAC have a cylinder head solution for your Petrol or Diesel vehicle. | | | Cylinder head conversions for bikes as well! | | SAC don't have any bike workshops but that doesn't mean we can't do your bikes head, be it a super bike or a quad you name it we can do it. Sure, the philosophy of how a head flows before and after a good porting job is consistent to almost any four-stroke engine. | | Super bike heads generally flow quite well in standard form, it's really all about a hand finished personalised head or a perfect one for that matter. Quads and off-roads on the other hand, need some attention to make them as good, so if you own one or know someone who does then you should be in contact with SAC Engineering at 016 981 1033 | | | Loose Heads & Trade Enquiries Welcome | Situated in Vanderbijlpark, utilizing state of the art equipment and employing only the best available staff, SAC Engineering has the ability to deal with loose heads and trade enquiries. | You can call us directly if you are in the trade or if you have a mechanic and or workshop other than SAC doing your work.
