In my humble opinion torque is what gives you acceleration not BHP. BHP is simply a mathematical figure arrived at by multiplying the torque by the RPM then dividing by a constant. It is therefore pretty meaningless in terms of acceleration. High BHP figures are often achieved by using high revs, great for a circuit car but not much use on the public highways.
My aim is a fat torque curve with a smooth, progressive delivery across the rev range which is why I'm chucking a V6 24 valve Cossie lump in mine. I recently saw a BHP/Torque graph for a similar engine that gave over 180 ft/lbs of torque at just 2000 rpm and just climbed in a near straight line from there to the 5800 rpm rev limit, max BHP at 5800 was a healthy 233BHP.
Could be fun
