I agree with 1-ton. Nitrous is not for the faint at heart. If you do not set it up right, you will blow your engine. Also, a supercharger is rather inexpensive if you add up the price of filling your nitrous bottle often.
If you really want to beat him, get a vehicle that is not your daily driver, build a nitrous engine with the correct crank shaft, rods, pistons, cam shaft, heads, intake, and ignition system. It sucks having your daily driver broken down because your pride got the best of you.
Hopefully you are racing on a track. Street racing is not only dangerous and illegal, but it is one the most stupid thing you can do.
