Very right Roy bhai. The only way by which we can minimise turbo lag and still have plenty of top end power is to do what the big guns of automotive world are doing - Sequential Turbos. One smaller and another larger turbo. The new BMW M5 uses a sequential twin turbo and pumps out, hold your breath, 650Nm at just 1500rpm! That is the power of engineering. And a mercedes V12 twin turbo petrol pumps out 1000nm at 2000rpm. Big petrols can surely be as torquey as big diesels. Gurjinder.
