An added bonus of the fart can is an insta-orgasm every time you goose it. Vibrates them cojones pretty good, so I'm told.

Seriously, though, Streets has the right idea. Learn to drive good, save you money til later. Then when you hit 18, fix it up like you want to. Then you will have the money to do it. Take a few auto tech classes to learn bout it, then by the time you are allowed to do it, you will be able to.

Depending on the year of your car, this may work or not. The later the year, the better. You have probably seen those instant 10 HP boxes you can use on your car on ebay. It amounts to a $.50 cent resistor jobbed into the air temp sensor available at radio shack. Fools your car into thinking it is getting cooler air, so it will run richer. Look it up on the internet. I'm not going to post a link cuz I don't want to be the one to get you in trouble. Fast, cheap, easily reversable if your mom wants to take a look.
