A6 with 500+ hp?????
Greetings Fellas (and Ladies)... I'm seeing these Youtube.com clips of suped-up Mustangs and 350Z's with 500+ hp... I don't know anything about which types of engines are best for upgrading and I'm just curious, can an A6 (year 2005 and up) be modified to kickout 500+ hp? I don't much like the older A6's or I'd be interested in the RS6..
Appreciate the insight..

Almost any motor can be modified to produce 500 HP.
The questions are how much are you willing to spend and how long do you want it to last?
They get 1200+ HP out of a top fuel dragster for 7-8 seconds. 800+ HP out of a 400 ci alcohol burning supermodified, 700+ HP out of a 358 ci NASCAR motor for 500 miles, so 500 HP is easy. Just bring MONEY!
PS for every one of those hot stangs you see on Utube there are a bunch of pimply faced kids trying to figure out what they are going to tell mom and dad about their broken motors. I know I was there once!

NH USA you're definitely on point with that...All of the videos I watched had kids talking in squeaky voices...guess their voices didn't drop.
At 500 hp I would like it to last as long as possible (or 2-3 years until I can upgrade). Nothing for everyday racing....just like to have the power just in case...But I don't see many M's or AMG's on the road looking to race anyway.

If you have a 4.2, PES has the G4 whch produces in the high 400s. (reliably as well)
The 3.2 will never in its life make that kind of power.
The RS6 in a joke, too much costly to maintain. ( sorry RS owners, but they are stupid expensive )
The 2.7T will make that if equipped with K04s, but thats only in C5 generation cars (00-04)
Also could look at a C6 S6, with the V10. 435 hp stock. With a tune and exhaust, would be about 450. Close to 500...

It's actually more like 7000+ (they really don't know b/c there isn't a dyno built that can register the power)
SORRY FOR THE HIJACK, but these facts NEVER cease to amaze me!! I've went to the Gatornationals the last few years and if you've never seen a Top Fuel car run in person, it is definitely "bucket list" worthy!!
* One dragster's 500-inch Hemi makes more horsepower then the first 8 rows at Daytona.
* Under full throttle, a dragster engine consumes 1 1/2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747 but with 4 times the energy volume.
* The supercharger takes more power to drive than a stock hemi makes.
* Even with nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly-solid form before ignition. Cylinders run on the verge of hydraulic lock.
* Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.
* At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitromethane measures 7050 degrees F.
* Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.
* Spark plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression-plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting off its fuel flow.
* If spark momentarily fails early in the run, unburned nitro builds up in those cylinders and then explodes with a force that can blow cylinder heads off the block in pieces or blow the block in half.
* Dragsters twist the crank (torsionally) so far (20 degrees in the big end of the track) that sometimes cam lobes are ground offset from front to rear to re-phase the valve timing somewhere closer to synchronization with the pistons.
* To exceed 300mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. But in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8G's.
* If all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs $1000.00 per second.
* Dragsters reach over 300 miles per hour before you have read this sentence.
Did you know …
… that the nitromethane-powered engines of NHRA Top Fuel dragsters and Funny Cars produce approximately 7,000 horsepower, about 37 times that of the average street car?
… that one cylinder of the eight cylinders of a Top Fuel dragster or a Funny Car produces 750 horsepower, equaling the entire horsepower output of a NASCAR engine?
… that the gasoline-powered engines of NHRA Pro Stock cars produce about 1,200 horsepower, about eight times that of the average street car?
… that an NHRA Top Fuel dragster accelerates from 0 to 100 mph in less than .8-second, almost 11 seconds quicker than it takes a production Porsche 911 Turbo to reach the same speed?
… that an NHRA Top Fuel dragster leaves the starting line with a force nearly five times that of gravity, the same force of the space shuttle when it leaves the launching pad at Cape Canaveral?
… that an NHRA Funny Car is slowed by a reverse force more than seven times that of gravity when both parachutes deploy simultaneously?
… that NHRA Top Fuel dragsters and Funny Cars consume between four and five gallons of fuel during a quarter-mile run, which is equivalent to between 16 and 20 gallons per mile?
… that NHRA Top Fuel dragsters and Funny Cars use between 10 and 12 gallons of fuel for a complete pass, including the burnout, backup to the starting line, and quarter-mile run?
… that NHRA Top Fuel dragsters and Funny Cars travel the length of more than four football fields in less than five seconds?
… that NHRA Top Fuel dragsters can exceed 280 mph in just 660 feet?
… that from a standing start, NHRA Top Fuel dragsters accelerate faster than a jumbo jet, a fighter jet, and a Formula One race car?
… that a fuel pump for an NHRA Top Fuel dragster and Funny Car delivers 65 gallons of fuel per minute, equivalent to eight bathroom showers running at the same time?
… that the fuel-line pressure for NHRA Top Fuel dragsters and Funny Cars is between 400 and 500 pounds, about 20 times greater than the pressure on passenger-car fuel pumps?
… that depending on size and angle, the large rear wing on an NHRA Top Fuel dragster develops between 4,000 and 8,000 pounds of downforce?
… that the 17-inch rear tires used on NHRA Top Fuel dragsters and Funny Cars wear out after four to six runs, or about two miles? Some brands of passenger-car tires are guaranteed for 80,000 miles.
… that it takes just 15/100ths of a second for all 7,000 horsepower of an NHRA Top Fuel dragster engine to reach the rear wheels?
… that it's desirable for an NHRA Top Fuel dragster to race with its front wheels inches off the ground for about the first 200 feet of the run? This ensures proper weight transfer to the rear wheels, a crucial part of a good launch and quick run.
… that the nitromethane used to power the engines of NHRA Top Fuel dragsters and Funny Cars costs about $30 per gallon?

Yes, it's possible. I'd start w/ the 4.2 or 2.7T though and the 2.7 isn't going to do it w/out big turbos - larger than the KO4s suggested earlier. A 'G' series turbo for sure, but then there is the tight fit, custom exhaust work, tuning, etc. 500hp is still a lofty goal though and I personally would start to worry about the quattro system. I'm not sure what it's designed to handle, but at almost twice the hp of most stock offerings, that's quite a bit to handle. I know I can't double the horsepower in my Z28 and expect the trans or rearend to hold up to launches...

Wow thanks for the input fellas! Even though you'd have to have the engine rebuilt, it would make a difference if you had a 3.2 instead of a 4.2 right?
I don't know any shop that rebuilds the German engines, but I've heard a lot about PES.
