I just had a quick squizz at the nitrous blowup thread - and nearly cacked my daks!!! Man, the thought of that nitrous letting rip just does it for me every time. Maybe I'm just easily amused...
Seriously though - why does anyone bother with nitrous? Don't people know that you can get oxygenated high octane fuel? The good stuff can help make 20->150hp on turbo engines, depending on the tuner's skill, and how wild the motor is. Not cheap at around $5 per litre, but then it runs through your existing fuel injection system - so no extra gear to install. Just hit the dyno rollers for a few hours with a laptop and PRESTO!! mmmm.... Horsepower......Torque... aaaaahhhhhhh..
