Cylinder heads for Diesel Vehicles
Times have changed and technology has moved on, diesel vehicles especially bakkies have become extremely popular.
The question is, have they got enough power?
If you own one or know someone who has one, decide for yourself!
The normally aspirated vehicle may have that extra 10% or so when used at sea level but drive them up at ±5,000 feet above sea level and everything changes.
Our cylinder head conversions for these vehicle's engine modification / upgrade don't make them race cars or add enough torque to make you think that you are driving a V8 or something like that.
When we are talking turbo diesels the cylinder head conversion really gives you two options, either you can have the same power as you had only with greatly reduced EGT's, or you can benefit from the extra roughly 15% of power should you so prefer.
Few people know that a diesel vehicles cylinder head modification / upgrade can be the result of an extra chunk of power.
To find out more about this exiting new innovation or for the extra peace of mind when deciding whether or not to have your diesel vehicles cylinder head conversion done, don't hesitate to call SAC on 016 981 1033
A cylinder head conversion can make holidays a pleasure!
Most or all manufacturers today design vehicles and their engines with a definite goal in mind, sure, climb into you car on your own and drive it with no load or obscene weather conditions at sea level and you will probably be almost happy with the performance. 
Now add your family, a boot full of belongings and drive the vehicle up to Johannesburg ±5000 feet above sea level on a hot summers day and feel the difference.
We have all been in this situation at some or other time and it's almost always when you are in a hurry or frustrated.
At this stage we haven't even spoken about pulling a trailer or a caravan and driving against a 20km/h wind. We all know this isn't pleasant at the best of times.
Petrol or Diesel leisure vehicles can benefit from a cylinder head conversion and most times the power gain will substitute for the losses created by the above scenario.
We don't all want to race our vehicles but we also don't want to be frustrated.

Now imagine how good it will feel to drive your vehicle after such a long trip and you are alone in it again and you have an extra 25% of power on tap, and you can enjoy it because no one is complaining.
