(OP)
Can anyone tell me what is Soft Turbocharging?. Any material related to Soft Turbocharging available on the net would be useful.

RE: Soft Turbocharging

At a guess, I would suggest it is a bulls**t marketing term to try to promote very low boost systems, without implying low or weak, but to imply gentle and durable, kind of like 95% fat free vs 5% fat.

This was classed as a soft turbo installation and it was done this way to increase the torque of the engine. Soft turbo charging is a way of getting a little more out of the engine without going whole hog and trying to extract every horse that they can.
