its always fun racing something that turns out to be faster than you as it makes u want more power, glad to see u didnt slag the nova off just cause it beat u like most people do
just worked out what power to weight ratio the nova and impreza would be and if u raced from a rolling start u can see why u got beat
a 700kg 150 bhp red top nova has a power to weight ratio of 217 bhp per ton
a 1400kg 230 bhp impreza has a power to weight ratio of 166 bhp per ton

and they are flywheel figures so once you take into account drivetrain losses plus the nova was stripped out you can see why 16v novas are so quick
