What's the best way to launch a diesel off the line?
I've got a W204 C320CDI with the V6 3.0 litre turbo diesel. I have a DTUK tuning box and I'm now at approximately 190kw and 590Nm.
My best 0-60mph time is 6.28 secs as measured by my GPXPro I use on my track bike. I let the rear tyres down to 15 psi cold and had about a quarter of tank of diesel.
It seems to accelerate faster if I slowly depress the pedal rather than floor it. It's not a natural thing so you tend to push the pedal past the pressure point too quickly and I'm sure it slows down. This is my first high performance diesel so I don't know all the nuances yet. I know it has a fixed opening air intake and the throttle adjusts the amount of fuel injected rather than adjusting the amount of air as in a petrol engine. That's why I think you need a different technique to accelerate quickly.
Its the first 20m or so that seems to be the main problem. An LSD would help for sure.
I tried loading it up on the TC as well but I'm not sure if that helps. I'd love to crack a sub 6.00 second time.
Any suggestions or hints are welcome.
