1 question and 1 report here.

I want to increase the torque and response of my CLK320 Cab esp before 3000 rpm. After 3000rpm, it's great and I dont need better.

Any exhaust fit for this purpose? As I heard, most exhausts increase the middle power band but decrease the low power band.


And, I installed the water injection system. I'm now testing it with water and later will try methanol/water mixture.

I feel the car faster and the response much better esp during start-up and uphill. However, no increase for 0-100 acceleration.

Will try methanol/water mixture later and stay tuned.

What is the water injection system??

I put the photo and comment ther.

Am i the only one who thinks that is the most ridiculous thing ever created?

Water Injection, or alchocol/propane injection is really only necessary on turbocharged or supercharged cars, I see no real need to use it on a normally aspirated engine. The purpose is to cool the intake charge after it has come through the intercooler. With this, in general you are usually able to run a leaner A/F ratio, more boost and your engine is less likely to detonate. Propane or alchocol injection can effectively actually raise the octane of fuel, once again allowing higher boost with less detonation.

I would have to agree with "J Lucas", I do not see why you would use this on a normally aspirated engine, especially the 3.2L V6.

I read many documents and research papers about Water Injection. They DO also help NA engines, but not as much as Turbo engines -- that's true.

Adding water, theoretically, can save some fuel. But I havent tested it on my car yet. Adding methanol/water mixture, by theory again, can increase power. I shall test this later and
let you know.

But it's certain that the response of the car is better after installing the water injection.

supercharged ie clk 230k in EU or the new 209 clk 200k might have a bit of a use for this water injection. Would like to see some results off one of those cars.
