my engine is far from stranded, and has massive torque from 3000 rpm to 6500rpm ( goto love turbo L28 ), I have no dought it will do 250km/h as I have had my 260z do 240km/h with worse aero and a lot less powerful engine, im fairly sure that It would never do 290km/h as im not that stupid to try, I was just shocked that it could potentially go so fast, its quite scary really.
