so you have seen plenty of sti's dump the clutch and go, yet youre asking me if i'm sure they can do it? i'm confused. and noone is comparing an sti to an a4... we were just saying why that kid doesnt beat sti's.
ORIGINAL: chaos92287
that kid has various videos of his car on youtube, he's done 6k clutch drops before and they've all gone well, but that vid shows what happens when your an idiot and think your STI's tranny is gona survive repeated 6k drops. i can do 6k drops no prob tho
but its not the best way to launch
honestly tho, a4's shouldn't even be compared to STI's. two totally different cars built for totally different purposes.

WHat, you telling me i can have my ko3s hold 20psi at 7k
I love when diluted people. This guy is now in with kemp, same with the dood that think he can pull on sti's.... sorry, modded sti's

heres a lesson for you...
Air density decreases 3% at each 1000 feet of elevation above sea level. As the air gets "thinner", the compressor wheel must spin faster to maintain the same psi of boost, however, this often makes the turbo run a higher rpm than is efficient, which makes you lose serious power... ever notice how youre turbo stops pulling when you are at high engine rpm... its because its running out of its efficiency range.

Actually bud, go check your facts; you will find you are very wrong.
A little common knowledge about FI and compression will tell you all you need to know. There is less air for a N/A engine to run. Since there is less air obviously less power, however when you run say 10 psi; you're still compressing the air to the same exact PSI you would be at sealevel. While the altitude effects all cars, it has far less effect on FI cars.

Wow, mis-information like this is why audiforums is the butt of audi community jokes. There is a reason why things like planes and Hillclimb cars are turbocharged as opposed to N/A

Spoiler: Oxygen is flammable.
Spoiler 2: Oxygen levels decrease with higher elevation
Spoiler 3: Turbochargers in jets compress what little air there is, thus more "bang for the buck" than a N/A engine which would provide so little oxygen, it wouldn't make as much power.
Spoiler 4: Turbochargers on jet engines use alternate technologies and are probably quite a lot bigger to maintain efficiency.

Uhh, no ****? Provided you're not maxing your turbo which they certainly arent from the factory it can compensate when a N/A engine can't.

Why don't you read what you're own people have to say before you call me dilusional! You're the dilusional one, prove me wrong. Otherwise i'd expect an appology for calling me out when you don't know a damn thing about racing or building engines.

There are many other sites and links out there I can post for proof of this; if you're dilusional mind requires more links and proof please let me know.

RE: How fast is your a4?
didn't I say a lot of threads ago, I have nothing to prove? I certianly don't need to explain myself. You guys do an awsome job trying to figure it out and argueing with each other.It's funny listening to you guys trying to figure it out. By the way, "all" things done are not listed. "Checkmate"
