there are a few well tried "tricks" to improve both power delivery and fuel consumption on V8's. I have some 34 years experience in this. There will be no earth shattering difference, but you will end up with a more responsive car and have more fun from it.
I assume, that your V8 is a Manual, here it goes:
1. Make sure that the suppressor plugs (the one that fits on to the spark plug) are in good condition. Measure these for resistance hot and cold
2. Fit NGK plugs with the "ET" suffix, the "T" stands for three mass electrodes. They will give better flame propagation and perform better especially under heavy load. On my MB 560SEL I get some 0.7lt better consumption just from these plugs.
3. Treat engine, transfer case and diffs with Poly-TFE "Engine" and the manual gearbox with Poly-TFE "Hydraulic". This will add some 10% more power delivery at the rear wheels. It takes some 4000km for this to work properly and has to be repeated after 80'000km.
4. Use 93 Petrol at the Reef and 95 Petrol at the coast. There is no benefit to use 95 petrol at Reef altitude.
Poly-TFE is available from Seydlitz Werkstatt in Constantia Park and also from Dirk van der Westhuizen of Forktruck Solutions in Bellville.
I trust that I have been able to assist you. The above tricks have been well proven and are currently used in all our vehicles locally and in Switzerland.
