Automotive engineering has certainly had to change over the years, and it has advanced to such a degree now because 1.4 litre cars are delivering more power and efficiency than the so called 3.0 litre Big Six cars of a few decades ago. |
This is thanks mostly to their powerplants or engines being far better engineered than they were 30 years ago. |
Not very many street cars at all, never mind real race cars, of the era could rev to around and beyond 8 000 rpm, but that has changed, today many new generation cars rev here and beyond all the time. |
To further entrench this march of technology, one just has to look at motor bikes and quads today, which by the way SAC Engineering also has the full spectrum of cylinder head repair services and valve replacement options for. Superbikes now easily rev beyond 15 000 rpm and quads beyond 13 000 rpm in stock standard form. |
But being the cylinder head specialists means that this evolving world is nothing new to the team as SAC Engineering, because in our high tech world, precision engineering is the order of the day where the tolerances and measurements are minuscule, with the days of one tenth tolerances long gone. Click here to get an SAC consultant to advise you! |
As you can now tell, these high revving engines and technologically advanced engine control systems require tolerances around one-hundredth and even one-thousandth of a millimetre in the cylinder head and valve train. |
So understanding that minute attention to detail in measurement and machining is of vital importance in each and every cylinder head and / or valve that is produced from our engineering shop. |
And you can be assured that the same principle is applied to each and every order specifically created at SAC Engineering. |
It goes without saying that this sort of bespoke and individual quality requires extra time, highly skilled time we might add, and this costs, but no more than you would reasonably expect to pay anywhere else in the world. |
We are most certainly market competitive when it comes to engineering and performance part pricing, but we are not an over the counter bargain budget and quick fix facility. |
No mass produced items here, we carefully and meticulously engineer and create hand finished cylinder heads and valves regardless of whether it is an OEM spec cylinder head or a state of the art race spec cylinder head that can do duty on any race car at any track. |
Just as can be expected with the range of valves that we offer, these are also by no means mass produced production line quality valves. |
We make each valve to a highly technical and precise specification by hand and machine. |
Our valve making process has been optimised as far as possible but not to compromise quality. |
And speed of completion is certainly not a factor in the finished product, unlike in a production line where speed is everything. |
It is worth noting that we are probably the only engineering shop in South Africa that can produce a valve to any spec, shape or size you might require in the quickest time. |
And it makes no matter if you require a one off sample or if you need them in bigger numbers, we are still able to help you quicker than trying to source and get valves delivered from overseas. |
There are many of our competitors in the cylinder head industry that can modify an existing valve, which is where we started almost thirty years ago. |
And yes we can do that too, but in today's high performance world this is not enough in terms of the quality and precision required for a proper rebuild. |
To put this in perspective, a basic refurbishing job on a cylinder head can take up to five hours to complete while a full blown race cylinder head could easily run up to fifty hours if all the effort and time is added together to bring you what would be the best and most reliable performance your money can buy. |
Valves are pretty much the same and can take anything from one hour to three hours per valve to finish properly. |
For this process we only use the best quality parts and accessories and our valve billets or donor valves are all 21 4N stainless steel or better. |
So now when you add the cost of our imported billet valves together with an hour or two of skilled labour, you can quickly see that we can't compete with production line over the counter type products that drop in a a production bin every minute or so. |
At SAC Engineering our team ,as to be expected, are all highly trained and skilled people who are just as passionate about their craft as you are about yours. |
No hidden surprises, no matter how big or small the order, each and every job we receive gets our proper attention and is correctly costed with the labour being charged accordingly. |
We have to be honest and tell you that if it is cheap cylinder heads or valves that you are looking for, then you won't get them from us as our world class properly engineered products are not cheap. |
