i have a 129 model 500sl
i love the car and it works great 50K on the engine and the only thing ive had to do is change the clutch fan because it was running a little hot in traffic.
now as with every good thing, i wanna a little more juice on the stamp down.
are there any performance chips out there for this model?
a turbo or supercharger?
any help will do, as each extra horse will count
thanks
ryan
