Q: i just got a 2001 audi a6 2.7t, what are some cheap upgrades i could put on it to get over 400 horsepower? (250 stock). Also what are some cool rims i could put on my audi.
A: There are no cheap upgrades to get you to 400 horsepower. Secondly, horsepower is an imaginary number, calculated from torque. Thirdly, you don't have 250. You have around 190 or so, at the wheels. So, if you want 400, you need to almost double your output. Not cheap. Not reliable. Not worth it. Also, the WHEELS you have on your Audi are perfectly good.
