Default Audi A4 Increase speed

How can you make an automatic '01 Audi A4 1.8T with AWD go faster? If someone says chip what is that ?? Also how much $$ is it to speed up a car? Thank you!

1) Drive downhill
2) Have a tail-wind
3) No fat chicks in the car
4) Helium in the tires to lighten them up
5) What kind of a question is this?

ummm....step on the gas pedal harder.
good question though...really.

for the record, more weight doesn't make you go faster downhill. no matter the weight, gravity is the same.
a little physics knowledge for yall.

Actually, your physics knowledge is a little incomplete. When going down hill, gravity is not the only force. There is also the friction force of the road surface and the vehicle surfaces within the drivetrain, and the normal force which is equal and opposite to the gravity force on the road. Greater mass within the vehicle will cause the force of the car due to gravity on the road to increase, which will increase the normal force of the road pushing back on the car. This increase in normal force, based on Friction Force = Coefficient of Friction x Normal Force, will increase the force of friction, causing the car to not just be as slow, but actually slower, because the gravity has more friction to overcome.

I won't yell search at you cause I can tell your new to any ideas of modding, and you didn't bring up a BOV. So heres the low down...

The best way for you to speed up your car is a chip, a chip is just a re-flashed ECU. Some companys you can look into are, APR or GIAC, possibly even REVO. Now a chip will run you $500 dollars and its best to have done at a local dealer with the brand names I listed, just go to there sites and find one near you. With a chip you will need a Diverter Valve which will run you $35-135 depending on who you go with, you need that because the chip will make your turbo run a little harder and give you more PSI that your stock Divrter valve can't handle, chips are reliable and safe and offer 30-45hp... There is a big difference in speed and its the best bang for your buck.

Now with a chip most people will say you need a full cat-back exhaust to offer less restriction and give your car that flow it needs, especially since its chipped. That will run you 800-1000$ for the exhaust and an install. Companys for that are, Milltek, Borla, AWE. Good luck and I hope that helped, if you got any more questions just post up and I'll be happy to help.

thanks. you just brought back some pretty painful memories of 11th grade physics. [:@]

Thank you Amze for your help! And yes I am completely new to this didn't realize there was a hole info section for newbies.
I'll check out the info you gave me see who around town could do it for me =)
I've been challenged to a race against a firebird TA and the individual constantly trashes Audi's really annoys me anywho figure I should tune up my car before such an occasion. It might take a bit of $$ to get it up to a TA hp but I'll find out
Thanks Again
