The torque converter stalls ~2krpm, not enough boost to do much (especially with 2.65 gears) on launch and powerbraking doesn't change that.

I'm considering a higher-stall TC as an alternative to a shorter rear screw for faster launches, would certainly shave .5-1sec from the course time IMO.

I had a 190D 2.5turbo, we didn't get them with the manual transmission over here though. The 300D Turbo is a faster car (by the numbers), one more cylinder and only 300lbs more car. The 190D did have a wheelspin problem even with the auto-transmission, I think the TC stalled closer to 2200rpm.

What's the final-drive ratio on your car? In the US the 190D 2.5turbo is also a 2.65:1.
