SheepyRace, a California-based performance shop, eventually acquired this damaged Audi R8. The front end was fixed, and a twin-turbo kit was added. In addition, a pair of brand-new coilovers were installed in place of the air suspension. The turbocharged R8 now has almost 1,400 horsepower, necessitating a reliable suspension arrangement.
SheepyRace improved the basic seven-speed dual-clutch transmission in addition to increasing power. The normal transmission’s parts would have probably broken due to the increased power.
WhistlinDiesel brought his updated Audi R8 to some street racing to put it through its paces. These runs are significant in part because they demonstrate the R8’s twin-turbo kit’s speed in context. A twin-turbo R8 by Underground Racing managed to finish the quarter-mile in 7.695 seconds at 196.76 mph, albeit we don’t have official performance numbers.

The Audi R8 uses natural aspiration, right?
The always outstanding Audi R8 is offered as a coupe and a roadster (also known as a Spyder). There is neither a turbocharger nor a supercharger in this sports car’s naturally aspirated V10.
The V10 R8 has a turbo.
At the drag strip, electric cars enjoy crushing gas-powered ones, but internal combustion engines are still in the game. In a recent Hoonigan film, a 2021 Tesla Model S Plaid competes in a series of 1,000-foot drag races against a powerful, upgraded 2018 Audi R8 V10 Plus to discover which car is faster.
The 5.2-liter V10 engine of the R8 has two turbochargers, making it powerful. The engine is rated at 1,700 horsepower (1,267 kilowatts), and Audi’s Quattro all-wheel-drive system transfers the engine’s power to the ground. With 1,020 hp (760 kW) listed as its output, the Tesla isn’t a slouch. Although heavier than the Audi, the dual-motor Tesla also boasts all-wheel drive. The Audi weighs 1,100 lbs (498 kg) less than the Tesla, which weighs 4,828 lbs (2,189 kg). It’s a wide gap.

Instant torque is an advantage that electric vehicles have over gas-powered ones. But not even Tesla could generate enough power to repel the Audi. Both cars took off from the starting line for the first race, with the Audi pulling away from the Tesla. The EV was unable to close the deficit and crossed the finish line several car lengths behind the R8 as the Audi maintained its lead. Simply put, the R8 has a lot of power.
R8 is twin-turbo.
The car has Underground Racing’s improved DCT gearbox, which includes billet for the gears, input and output shafts, final-drive gear, and AWD shaft, in addition to the twin-turbo configuration. A standalone engine management system is also available.
This R8 is also used by Underground Racing for longer runs. Previously, the identical vehicle was capable of reaching 244 mph (393 kph) in the standing half-mile (804.7 meters).
A third generation of the R8 is apparently being developed by Audi, although it may have a significant engine shift by switching to an EV or at the very least a hybrid. However, the new model might not come out until 2022.
What model of Audi is twin turbo?
The sexiest version of the A7 Sportback, the second-generation Audi RS 7, will go on sale in Canada sometime in 2020. A twin-turbocharged V8 engine with 590 horsepower and 590 pound-feet of torque is housed under the hood.
How quick is a R8 with two turbos?
In the past ten years, I’ve frequently observed women competing in various motorsports, which may not have been the case 30 or 40 years ago. And most of the time, if their cars are prepped properly, they are quite skilled and can easily keep up with the guys. But in the end, you have to ask yourself: How many mothers do you know who can perform low-eight-second runs at the drag strip?
If I’m not mistaken, Brittany Force is the NHRA’s quickest female competitor. She enjoys Funny Car Dragsters, and I’ve even witnessed her complete runs in under four seconds at a trap speed of 338 mph (544 kph). Even while the Audi R8 we’re looking at today isn’t even close to that quick, it’s nonetheless amazing. It still has a stock powertrain, but it has a variety of modifications that enable it to run the quarter-mile in under nine seconds (402 meters).
The twin-turbo kit on this V10-powered R8 is from AMS Performance, and it costs $26,750. Depending on the other enhancements included on the application, it may produce between 800 and 1,600 horsepower. Also fitted is a Sheepey Race intake manifold, which is a billet improvement and costs a pretty penny as well. You’ll need to spend $15,000 just on one component.
Additionally, a Motec ECU handles all the computational tasks, and Sheperd Transmissions, an Ohio-based manufacturer, has updated the transmission on this vehicle. Amie Palo, a Texas native, is the current driver; Tony Palo, her former husband, previously operated the vehicle. But since she frequented the track, she made the decision to try herself. She can now let it rip down the quarter-mile after realizing that her kids have grown up a bit.
She makes several laps of the course in an effort to beat the Audi R8’s previous speed record for a stock motor car. I have to admit that I don’t recall the last time I saw a R8 moving so quickly! She does an 8.48-second pass with a trap speed of 168.89 mph (271.80 kph) during the first run that was recorded! Later, she defeats a Nissan GT-R that has a very outstanding appearance by performing an 8.46-second pass.
As she intends to take things even farther with the car and get a fully-built engine in it, her goal for this competition was to break the current world record of 8.23 seconds. It follows that she will soon try to complete a run in under eight seconds, and it will be interesting to see how fast she can push this R8. She keeps doing run after run throughout the competition, and improvement can now be seen.
She does an 8.43-second pass to slightly better her first time before stepping it up and achieving an 8.279. When kept within boundaries that won’t destroy the engine, the engine appears to be at its limit, and minor adjustments to the transmission were made to improve performance. Amie put in a strong performance right away, clocking in at 8.23 seconds and 170.04 mph (273.65 kph)! Although there was initially some misunderstanding surrounding the R8 stock motor world record, it appears that Amie was able to surpass it.
How does the Twin Turbo function?
For many years, turbochargers have been the pinnacle of the automotive aftermarket, and pushing engine blocks to their absolute limits with a twin-turbo arrangement has the potential to unleash absurd power increases. Whether your car already has a turbocharger or you installed an aftermarket system, petrolheads looking for more horsepower frequently turn to the quickly rotating turbine blades.
Twin-turbocharging has been employed in illustrious vehicles like the Mazda RX-7 and Ferrari F40, so let’s examine how it operates and the various varieties on the market.
To increase horsepower, a twin-turbocharger forces air into the engine’s cylinders using two turbochargers of the same size. Before entering the cylinders, the exhaust gases are recycled, divided between the two turbos, and often mixed in a common inlet. By forcing more air into the induction chamber, the engine is able to produce more potent combustion strokes. An arrangement like this is referred to as a parallel twin-turbo system.
Both systems have advantages, but a twin-turbo has the ability to reduce turbo lag in comparison to a single turbocharger performing all the work. Lower boost pressures are delivered by the twin turbo to lessen turbo lag, but the combined output of the two turbines is still quite substantial.
Instead of one huge turbocharger forcing air through intricate plumbing to make its way around the engine compartment to the necessary cylinders, each turbocharger in twin-turbocharged V-shaped engines, such as a V8 or a V6, is often given its own bank of cylinders. Without as much ductwork to travel through, each turbo can spool up more quickly and directly serve its bank of cylinders. Parallel twin-turbocharging, which substitutes two somewhat smaller turbochargers for one larger turbocharger with larger vanes, can help reduce lag.
There are, however, a few additional twin-turbo configurations that boost power in a somewhat different way.
Sequential twin-turbos
A small-vaned turbo is used in this configuration to provide low exhaust gas flow at low engine speeds, and a second, much bigger turbo takes over once the first turbo has had a chance to spool up.
In order to maximize power delivery at a rev range that was previously unusable for the majority of single turbocharger setups, a compression valve is positioned in front of the large turbo to ensure that all of the lower energy exhaust gases produced at the bottom end of the rev range are isolated to the smaller turbocharger. The compression valve is slightly opened as engine speed increases, allowing the larger turbine to start spinning. The secondary turbo can then operate at its most efficient level because the valve is triggered to fully open at a specific airflow volume.
Since the secondary turbo may be adjusted to exceptionally high boost while the primary turbo eliminates any low RPM lag, sequential turbocharging practically eliminates the drawbacks of single turbocharging and outperforms a parallel configuration. With a sequential arrangement, car modders may also get very crazy, changing the ratio between the tiny and large turbochargers to produce some seriously terrifying power deliveries. The best platform for sequential turbocharging is probably best pictured as the MkIV Toyota Supra.
Staged turbocharging
Similar to a sequential configuration, staged turbocharging builds air compression to extremely high levels before entering the engine’s cylinders through a “stepped” process. The air is compressed further after passing through a somewhat larger turbocharger after a smaller one. In a staged system, the final boost pressure can be significantly higher than in a typical twin-turbo system, but it is quite disastrous in terms of latency. This is why diesel engines with high compression ratios and low rpm ranges typically employ it.
Twin-scroll turbos
To avoid the bother of employing two turbochargers, you might choose a twin-scroll turbo. This design essentially combines two turbochargers into a single housing while strategically distributing the exhaust manifold throughout the cylinders of the engine. The exhaust pulses that coalesce before and inside a conventional single-scroll turbocharger produce irregular and turbulent airflow. The exhaust pulses can be kept distinct and enter the turbocharger through their own inlets thanks to the twin-scroll arrangement.
Modern automobiles are increasingly using twin-scrolling, which has greatly improved the performance and packaging of turbocharging. As a result, even four-cylinder engines equipped with twin-scroll turbos can produce as much power as a six-cylinder engine with a single turbo from a decade ago.
It’s an incredibly cool way to boost the performance of your engine, whether twin-turbocharging is simply a pipe dream that will never materialize in your unfinished project vehicle or whether you’re the happy owner of a car that already has it as standard.
Have you given your automobile dual turbochargers? Or would a slow single-turbo system or perhaps natural aspiration suit your tastes better?
Which motor powers the Audi R8?
The Audi R8 performance Coupe was created in tandem with the R8 GT3 LMS race car and shares over 50% of its components. Its 5.2-liter V10 FSI engine, which can generate up to 602 HP, is its standout feature.
What Audi R8 V10 has the fastest speed?
The new Audi R8 is faster, more powerful, and offers even better performance. It also has a more distinct road presence. It will be offered in Coup and Spyder body styles with 570 PS and 620 PS in the performance quattro versions.
When ordering for the new R8 begins in the UK early next year, Audi Sport enthusiasts will be able to purchase one.
The current R8 range’s highlights include increased power, torque, and performance, including many models with top speeds beyond 200 mph, as well as even better handling precision as a result of suspension and steering upgrades.
In the “regular” R8 Coup and Spyder V10 quattro, the naturally aspirated V10 engine’s power has been raised to 570PS. The top V10 plus variants in each body type will use the moniker “V10 performance,” matching them with the most potent Audi Sport vehicles; they receive a 620PS power boost.
Engineeven more power and torque
Quick reaction, blazingly quick high-revving, and a distinctive sound The 10-cylinder, naturally aspirated engine is the brains of the Audi R8. The basic unit now has 30 PS more power (570 PS) and 10 Nm (7.4 lb ft) more torque (550 Nm, 405.7 lb ft), all of which are available at 6,500 RPM (rpm). The Spyder and Audi R8 V10 Coup quattro both accelerate to 62 mph from 0 in 3.5 and 3.4 seconds, respectively, before topping out at 200 mph.
The Audi R8 V10 performance quattro’s 5.2 FSI engine now produces 620PS instead of 610PS and has a max torque of 580 Nm (427.8 lb ft). An upgraded valve train with titanium-based components is what led to the increased torque. The Coup and Spyder both reach 62 mph in under 3.1 and 3.2 seconds, respectively. The max speeds of these cars are 205 mph and 204 mph, respectively.
A particle filter is included with both engines to more efficiently minimize emissions.
Suspensionrazor-sharp precision
It has been tweaked to increase stability and precision even further. Both the electromechanical power steering and the optional dynamic steering have had their assistance levels adjusted. Across the whole speed range, changes between the various drive modes and feedback from the road are even more precise.
The comfort, auto, dynamic, and individual settings of the Audi drive choose dynamic handling system are now more obvious. Three more programsdry, wet, and snoware included in the performance mode as standard on the R8 V10 performance quattro. They adjust the important dynamic parameters to account for the road’s friction coefficient. The Audi R8 V10 performance brakes from 62 mph to a stop up to 1.5 meters earlier thanks to the improved Electronic Stabilization Control (ESC), and the stopping distance from 124 mph is up to five meters shorter in each case depending on the outside conditions.
Wheels measuring 19 inches have been factory-installed on the new Audi R8 V10 quattro. Audi provides red painted calipers as standard rather than black painted calipers as an option for the steel discs.
Designsharper and tauter
The new R8 models’ enhanced design is also notable. The lines on the singleframe radiator grille are flatter and wider. Large air inlets are divided by thick bars, and the hood’s flat slots are reminiscent of the Audi Sport quattro brand emblem. The broader redesigned front splitter emphasizes the sharper appearance. The R8 appears much wider since the air vent grille spans the entire width and the diffuser has been pulled upward. The air filter is located in the engine compartment beneath a new, three-part cover that comes in plastic or carbon fiber.
Depending on the engine variant, R8 customers can select one of three appearance kits that add different highlights to the front splitter, side trims, and diffuser. High-gloss black is the standard specification for the R8 V10 quattro with 570PS, while the top-of-the-line R8 V10 performance quattro with 620PS rolls off the assembly line with a matte titanium appearance. The performance version will also come in high-gloss carbon design.
The interior of the Audi R8 with its driver-focused design, new color options, and stitching is also part of the updated appearance. Customers have the option to customize numerous aspects of their Audi R8 both inside and out thanks to the Audi unique range.
During the first quarter of 2019, the Audi configurator and Audi Centers will accept orders for the new Audi R8.
