More power and better MPG Hmm I see a conflict here.
The plan of mercedes was to reduce the low end grunt and give better top speeds Good in Germany but not fantastic over here - if you are willing to sacrifice top speed you can do something here.
(You could get an ECU remap for Super Unleaded and this should yield better power and could potentially, as the engine burns more efficiently, bring down your MPG. You may like to try a split approach - better MPG (Lower power also) at low revs and push the torque envelope further up the rev range so you have more power on tap and less MPG at higher rev ranges. This is what most manufacturers aim at with their mapping.
You could bolt on some NOS - this will give a phenomenal power hike on your car. I also recommend a cone induction kit with a cold air feed - this will free up the top end revs a little although big engines like this are never particularly revvy.
Getting the head cleaned out and skimmed would increase compression but this is expensive for a V8 engine. If I were you I would speak to Brabus and see what they can offer you The AMG CLK55 shows what you are missing out on.
Weight reduction will also help you - these cars are extremely heavy. |
