We obtained a bit of throttle proud of our 2023 KTM 300 XC-W check bike. To our shock we managed to log virtually 200 hours (191 to be actual) of path time on the utterly inventory unit in a few seven month timespan. We nonetheless can’t imagine it however all these missed deadlines make sense now. We teamed up with AEO Powersports, REP Suspension, Race Winning Brands, Bulletproof Designs and a bunch of different trade main firms to utterly rebuild this 2023 KTM300XC-W. Here are the primary studio photos of our completed challenge.
Ray Rodden from Kinetic Ride Company was the person behind the wrenches on this challenge. Usually after we begin a construct the bike is torn aside, assessed after which the choices are made what stays and what goes. With this construct due to the sheer period of time on the bike just about all of the transferring and put on elements had been changed aside from the precise transmission gears.
Bulletproof Designs gives all kinds of things out there within the that division. We put in their billet aluminum radiator guards, chain adjusters, rear chain information swingarm mount guard and an upgraded set of wheels that changed the used up inventory models.
We went with a full Rekluse Core Manual clutch that options their Torque-Drive expertise as a substitute of the total auto model as a result of we appreciated the OEM clutch motion however wished a bit of extra adjustability and optimistic traction to the rear wheel. The engine obtained some further bling with a Specbolt Nickel Wurks {hardware} package.
Brad at Para Pros dealt with the engine tear down and rebuild. The crew at Sano Metal Finishing did all of the Vapor Blasting and specialty coatings. Seal’s and bearings had been changed internally utilizing kits from Pro-X, we used a Pro-Lite piston package from Wiseco and Andrew Langston with Langston Performance rebuilt the crankshaft.
Kickstands are a should on path bikes and the Fastway/Pro Moto Billet kickstand is likely one of the finest available on the market.
Another firm huge within the safety sport in TM Designworks, we’re utilizing a full protection skid plate , entrance fork lug protectors, rear brake caliper safety, rear rotor safety, rear chain information and chain sliders for one motive . They all work flawlessly!
The Seat Concepts ribbed gripper seat matches the Backyard Designs customized graphics and can hold us from sliding of the again of our newly refurbish path weapon.
The Scalvini exhaust is simple on the eyes and gives noticeable efficiency positive factors.
Increased gas storage with an IMS outsized tank means extra path and that makes everybody completely satisfied.
The most superior triple clamps you should purchase; the Luxon Gen3 clamps are full artistic endeavors developed with prime racers utilizing superior engineering methods distinctive to the motocross trade. Lighter and stronger than inventory they function adjustable offset and adjustable stiffness to high-quality tune your trip. Bores are end machined from the 7075-T6 aluminum after anodize guaranteeing exact alignment and eliminating slippage.
Mark Johnson and his total crew at Research Engineering Performance or REP for brief dealt with bringing our suspension again to life. Even with virtually 200 hours we once more had been shocked how dangerous the general situation wasn’t when every little thing was torn aside.
ICW straightened and braced up our inventory radiators making them off-road prepared.
Here is a bit of driving motion of our 200 Hour KTM300 XC-W. Stay tuned for a full overview.
Its improvement was stringent. Tests included 100 hours straight at full throttle and a deep thermal shock take a look at through which it was run at full energy to a coolant temperature of 100deg C earlier than being shut down, flushed with -30deg C coolant after which run straight again as much as 110deg C no fewer than 400 occasions.
The engine has three separate cooling circuits and two separate exhaust assemblies, whereas its administration system has some 42,000 parameters.
Fuel-saving expertise consists of environment friendly twin-scroll turbochargers and cylinder-deactivation expertise that on six cylinders shuts down the consumption and exhaust valves, gas injection and ignition under 3000rpm and 221lb ft in third to eighth gear.
By the time manufacturing ends, greater than 105,000 examples of the W12 could have been constructed at Crewe – greater than every other 12-cylinder engine within the fashionable period. The whole output of these engines shall be greater than six million horsepower.
An perception into the world of whisky
Macallan is the Bentley of whisky makers, in order that they inform me, and from the proof I’ve seen, I’ll gladly take their phrase for it. It is 200 years outdated this 12 months, and on its 458-acre property opened a brand new distillery in 2018 and a 12 months later a customer centre that’s a cross between a Bond villain’s lair and the Willy Wonka manufacturing unit.
The distillery homes 36 stills that make 12 million litres of spirit a 12 months. Just a dozen of the 270 folks working at Macallan are chargeable for making the 63.5%-proof spirit that gives 20% of the flavour of the whisky (it could actually solely develop into a Scotch whisky if it has sat in an oak cask for greater than three years), the remaining coming from the sherry-seasoned casks. At anybody time, 450,000-plus casks sit on the Macallan Estate, a few of them as many as 81 years outdated.
It seems that the world of high-end whisky has lots in frequent with the higher echelons of the automotive one. There are points round counterfeiting that require fixed developments within the cap and seal used on bottles for safety and there are speculators who will purchase uncommon, limited-run whiskies from Macallan after which flip them.
It will tighten its line on the throttle (though not by you coming off it, not like the 911) however doesn’t accomplish that as naturally as any longitudinally engined roadster from Affalterbach ought to.
It clings doggedly onto that feeling of stability that appears to be its chosen calling card. It’s all very ‘fast grand tourer’, moderately than ‘proper sports car’ and once more makes you surprise: the place’s the AMG-ness? Meanwhile, the 911 is trickier to steadiness however rewards precision and is prepared to bounce. It’s extra enjoyable.
Mercedes-AMG SL 55 vs Porsche 911 Carrera GTS Cabriolet: verdict
So the place does this go away us? It’s fairly clear-cut, I might say. One approach of framing the decision is to ask: does the reinvented SL get nearer to being a sports activities automotive than the 911 will get to being a long-legged grand tourer? Because if it does, chapeau AMG, because the end result could be fairly compelling, even at £150,000. But no.
The AMG is a tremendous cruiser, however the 911 is not any horse and cart and even in Cabriolet kind has the area and beauty for day-long drives. Then, on these final half-hour from motorway to in a single day, it is going to take the SL aside in nearly each measurable approach, and in a number of methods you’ll be able to’t simply measure, too.
That stated, there’s clearly fairly a little bit of potential within the SL. If AMG may give the Mk2 GT the identical dealing with aptitude as its predecessor but additionally the highway manners of the SL and, say, disengageable entrance driveshafts? What a factor that may very well be.
Mercedes-AMG SL 55 vs Porsche 911 Carrera GTS Cabriolet: winner
1st. Porsche 911 Carrera GTS Cabriolet
Road roar hampers its GT credentials, nevertheless it’s stunningly full in nearly each different respect. Subtler than the SL but additionally extra detailed and rewarding.
2nd. Mercedes-AMG SL 55
Fantastically succesful in isolation however considerably confused. Loses some GT slickness in an try and chase the 911 however by no means lands any convincing blows.
Similar to naturally aspirated engines Supercharged engines provide quick throttle response and smooth, linear power delivery.
Superchargers are mechanically driven by the engine and work more effectively when the air is cooler.
Supercharged engines offer increased power and low-end torque, making them a cost-effective way to enhance vehicle performance.
Superchargers have been around for much longer than the automotive internal combustion engine. The supercharged engine was first built in 1878 but was later used in airplanes in 1910. The main aim was to compensate for the power losses at high altitudes. However automotive superchargers would not become available until 1923 first used in Mercedes cars. Since then, they have evolved from the less efficient blower style to the more sophisticated twin screw and centrifugal supercharger used in modern automobiles.
In the modern era, supercharged production has become less common in favor of turbocharged cars. Having said that, it still remains a very effective way of making power without having a bigger engine. Just like turbos, superchargers can also be applied on almost any configuration from inline-four cylinders to big V-12 engines. In this article, we will take a look at the advantages of having a supercharged car, how they work and the types of superchargers available.

Supercharged Engines Are Similar To Naturally Aspirated Ones
One of the major advantages of an NA engine is its quick throttle response. Once the gas pedal is applied the car responds instantly with no delay in power delivery which is smooth and linear. The same power delivery applies to a supercharged vehicle, a supercharged car responds instantly and delivers its power in the same manner with no sudden surge or drop off in power. This is made possible because of how a supercharger works.
How A SuperCharger Works
A supercharger works in tandem with the engine, unlike a turbo which is driven by exhaust gases. Supercharges are mechanically driven by a belt connected to the crankshaft, this means they come on as soon as the engine starts. Once on, it forces cold air from the environment air into the engine which is used to create more power. Just like turbos, superchargers work more effectively when the air is cooler.
There are three types of superchargers:
Roots
Twin screws
Centrifugal
Roots: This is the oldest supercharger design with rotors inside that just trap air and send it directly into the engine. The pressure is determined by the amount of air being moved into the intake manifold. It is the least efficient form of supercharging and is the least favorable design. The roots superchargers are big, and bulky and stick well above the hood, they are mainly employed on old muscle cars and drag cars.
Twin Screw: This is the most common style of supercharger used in production cars like Hellcats, Mustangs and Camaros. These also have twin rotors that have a screw-like design meshed together. The air is compressed inside the rotor housing and sent through a smaller intake tube into the engine. This style of supercharging is more efficient and widely used among OEMs. It also creates a distinct whine which can be heard from inside and outside the car.
Centrifugal: This is the most efficient form of supercharging and looks very similar to a turbocharger. It works by powering an impeller which is smaller than a rotor and spins much faster. Impeller speeds can reach up to 60,000 RPM which is much faster than the engine speed which means it allows for much more airflow into the engine making much more power.
This style is famous among aftermarket tuners as it is used to build very powerful cars for drag racing. Most people commonly refer to these as Procharged cars because of the ProCharger branded centrifugal superchargers.
Supercharging is an easy and cost-effective way to get more power from your vehicle. Adding one would give you an average power and torque increase of up to 45 percent from the standard engine configuration. Since most of them are already made with a particular engine specification in mind, they come complete with supporting accessories to make the installation easier. The biggest advantage of this application is a healthy increase in torque compared to an engine with similar horsepower.

Supercharged V-8 Vs. NA V-10
A good example of the effectiveness of a supercharger is the C7 Chevrolet Corvette. Supercharged versions make more power and torque than the base NA V-8. Even in the world of supercars, the supercharged Corvette makes similar power but much more torque than a V-10 Lamborghini Huracan.
The added power is always available from start to redline just like a naturally aspirated engine. There is no drop-off in power since it runs off the engine’s crankshaft. As long as the engine runs, the supercharger is always ready to deliver the power needed.
Power At Any Altitude
The biggest advantage of this powerband is felt at higher altitudes where the air is thinner. NA engines suffer from power loss at higher altitudes due to thinner air but the supercharger greatly compensates for this loss by forcing more air into the engine. This ensures consistent performance in every situation.
This is one of the biggest advantages of a supercharged engine since they are mostly built with the capacity of the engine in mind. Almost any size of turbo can be put on an engine as long as you’re ready to build the internal components to match the power output. But superchargers have slight differences as they’re built with specific engine capacities in mind. This means before installing an OEM or aftermarket supercharger on a vehicle, the engine can already handle the power boost with minimal changes needed.
These minimal changes mean your car’s maintenance will likely be very similar to its naturally aspirated counterpart. There’s no doubt the maintenance cost will slightly increase but it is very similar to maintaining a regular engine since most components are still the same. Most OEM supercharged cars have base versions of the same engine and installing one later on won’t void your warranty when using a manufacturer-suggested supercharger.
