I've driven James' RB25 Cefiro which has the 2835 Pro-S on it - all I can say is it tears balls. It's not very laggy, but the mid range and top end is massive. MKDR33 - Either your guy's dyno figures are bullshit, or it's your hectic chrome wheels adding that extra 30kw, because I doubt your car is putting out that much power in reality, especially with a stock fuel pump.
