By almost anyone’s standards, Audi’s R8 with the Lamborghini-derived 5.2-liter V-10 is a fast car. The engine puts out some 525 horsepower and 391 ft-lb. of torque, which is enough to get the R8 V-10 Coupe from zero to sixty in 3.7 seconds, or 3.9 seconds for the R8 V-10 Spyder. Top speed on the coupe is said to be 196 miles per hour, which is annoyingly-close-but-just-shy-of 200 miles per hour. If you’re lucky enough to own either version of Audi’s 5.2-liter equipped R8, it’s easy to understand why you’d want to make it just a little bit faster.

Enter Heffner Performance, a tuner with a significant history of making Audis, Lamborghinis, Ferraris, Ford GTs, and Dodge Vipers faster, yet still docile enough to drive on the street. Their latest bolt-on package for Audi’s V-10 R8s - the Twin Turbo "bolt on" system with twin Garrett GT35R turbochargers at 6 psi - will get you 725 horsepower at the wheels, on 93 octane pump gas. That’s an increase of 200 horsepower from stock, yet the car retains its sophisticated, grand-touring demeanor.

Full story after the jump.

In Heffner’s own words, their upgraded R8 is the “most refined aftermarket twin-turbo car we’ve ever experienced,” and the tuner describes the onset of power as smooth and linear. That’s a very good thing, since we’d hate to experience a car that delivers a “harsh and abrupt” 725 horsepower, even if it did include Audi’s superb quattro all-wheel-drive system.

The exhaust note can be tuned to each customer’s expectations, which means you can have a 200 mile-per-hour R8 without setting off car alarms when you drive by. Heffner Performance sells the twin-turbo setup through its network of dealers, and each kit includes a 12 month, 12,000 mile warranty on the Heffner-built components. The company doesn’t list pricing on their website, but adding a reliable and well-sorted 200 horsepower to Audi’s R8 doesn’t come cheap. Still, if you’ve got the money to buy an R8, adding enough horsepower to get you past the 200 mile-per-hour mark seems like a reasonable investment to us.

It really looks filthy on its back part. However, I must say that I’m so impressed on its engine, which has an output of 725 horsepower, but I still noticed that there are lots of more powerful sports vehicle out there.

The R8 with Lamborghini derived equals a 725 horsepower at the wheel and a great engine at the back. Well done for Heffner performance.

Well, I would agree with that. The car is very powerful having almost 200 mph. I think the horse power will be about 700+. Insane right? But this is what we are waiting for. By the way, having this kind of power will surely consume a lot of gas. Hopefully, they can minimize that thing.

Wow! This production really shows on how reliable is the standard version of the Audi R8. The increase in the speed performance of this car is very impressive!

Wow. The top speed of the car almost reaches the world record for coupes. Having 198 mph is not a joke. The boost of the car is really impressive. I’m sure that its competitor is now shaking because of fear to lose the competition.

The styling of the car is quite impressive and I really like it more since they have upgraded the engine into higher speed performing vehicle! I would say that this is the most impressive aftermarket version that I have seen so far.
