2018 ZR / XF / M 8000 / 800 C-TEC2

2018 ZR / XF / M 8000 / 800 C-TEC2 Performance Products & Parts | Speedwerx Inc.

The wait is over! The all-new 8000 Series C-TEC2 794cc engine with Dual-Stage Injection (DSI) delivers increased performance and rideability in the 160-hp class. It provides crisp throttle response, outstanding mid-range and class-leading performance in addition to improved fuel mileage and reduced oil consumption.

You know we can't leave well enough alone though- we're already hard at work developing many performance parts and accessories for the new models with the same quality, durability, and of course the Straight-Up USA Horsepower that has made us known as the Worldwide Leader in Arctic Cat Performance! We plan on offering all of the same type of go-fast parts that turned the 800HO into a whole new animal, so stay tuned for further announcements on new products as the development continues...

  


April 2017- Supercharger Testing with Rob Kincaid and Dave McClure!


November Product Updates and Dyno Testing Info-


The early release of the 2018 8000 C-TEC2 models allowed us to get a jump start on all of the parts and accessories for this machine. In addition to the videos we showed you last spring where we were field testing the Supercharger and our Exterminator Kits, we had logged many miles testing clutch kits on the early build machines and have since made hundreds of pulls on our engine dyno testing various components and configurations.

After months of work, the cold air needed to finalize the specifications on components like the pipes and heads has arrived, so you can be assured all these new parts have been 110% tested and proven to meet Speedwerx standards before they reach your doorstep. Most of these new products are available for pre-order now and will ship once production parts are made in the coming weeks, but some parts are in stock and available for purchase right now. Here’s a rundown on the testing process and the parts are offering…

One of the biggest hurdles in building power on this new engine package is developing components that will make power without triggering the stock knock detection system correcting and detuning what are trying to do. We have the capability to monitor this type of data that is being read by the stock ECU and see potential problems before the ECU starts to make corrections (adding fuel and pulling timing)- this is well before it would trigger the deto light on the gauge and you notice a loss of performance in the field. This capability lets us know that the upgrades we are offering will be 100% safe and reliable and we will not be fighting the stock knock system with our parts. We test with 91 octane ethanol gas straight out of the pump from our local Holiday station, so it’s representative of the fuel you would find anywhere else around the country. When making runs on the dyno for comparison purposes, we make sure to get the engine and pipe up to full operating temp and make several back to back runs to ensure we are simulating real world conditions and to verify there are no significant losses on longer, hot pulls. When running the Exterminator Kits to establish the numbers seen here, we retested the stock engine to establish the baseline for comparison and it came in at 152hp @ 8200RPM with 97.4ft-lbs of torque @ 8100RPM on our SuperFlow engine dyno.

Our Stage 1 Exterminator Kits are a great choice for easy bolt-on power and performance at a lower price point, and you can easily upgrade to the Stage 2 spec down the road if desired. The Stage 1 consists of our Stealth Head Mod, all new VForce3R Reed Valves, a 2.5° Timing Key, a Hypershift Clutch Kit , and our new Aluminum Panel Vents. The Stage 1 peaked at 155.6hp @ 8100RPM with 100.9ft-lbs @ 8100RPM- that’s an increase of 3.6hp and 3.5ft-lbs at the peak, but it was up 4-5.5hp with a corresponding increase in torque throughout the midrange all the way up to where the gap started to narrow within the last 100RPM. This will translate into better acceleration in the field to quickly put you out in front of a stocker and keep you there.

The Stage 2 Exterminator Kits include all of the Stage 1 components, plus our Fat Daddy Pipe and Y-Pipe combo, a Dynojet Power Commander V Fuel Controller, and a High Flow Intake Vent Kit. The Stage 2 peaked at 164.3hp @ 8300RPM and 103.9ft-lbs at 8100RPM- an increase of 12.3hp and 6.5ft-lbs at the peak. The higher RPM and much improved over-rev power approaching 8500RPM means it will be much more forgiving on the clutch setup than the stocker and will have bigger wheels on the top end for the long pulls on the lake or the big climbs in the mountains.

The Stealth Head Mod with billet dome inserts is the key to unlocking maximum power and performance from the 800 C-TEC2. As previously mentioned, we are seeing a 4-5.5 hp gain in mid-range RPMs on pump gas with the stock pipe in our Stage 1 Exterminator Kit. At higher elevations, we expect gains to be in the 6-10 hp range on pump gas depending on the elevation and compression ratio. The head design allows us to add a 2.5° timing key while reducing knock readings detected by the stock sensor even with a compression ratio similar to stock, and without the need for a fuel controller when using the stock pipe.

The new VForce3R Reed Valves tie the whole package together with nice gains throughout the RPM range- we saw an improvement over the stock reeds of 2.4hp at the peak in the Stage 1 kit and 4.1hp with the Stage 2.

Our Fat Daddy Single Pipe and Y-Pipe combo with the Dynojet Power Commander V for the required fuel adjustments is what sets the Stage 2 apart from the Stage 1 and puts the big gap in the numbers over the stock machine on the big end. We tested about a dozen different configurations of Y-Pipes with the stock pipe and saw little or no gains, so we will not be selling the Y-Pipe alone.

As with the 800HO, we will be including a Cold Air High Flow Intake Kit consisting of easy to install Frogzskin vents as standard issue with the Stage 2 Exterminator Kits. We all know cooler air equals more power so they will be part of the complete package.

An Aluminum Panel Vent Kit in your choice of colors is included in all the Exterminator Kits as well. These are made from heavy gauge laser cut aluminum backed with stainless steel screen, so they look great and are very durable. They rivet in place on the front of each side panel and help reduce the heat underhood, which is especially important when it comes to belt life.

Testing with our Hypershift Clutch Kits on the stock machines was completed in the spring, however the recall replacement and fall production clutches are slightly different than the clutches used on the early build machines. Because of those differences, we will be testing them again very soon and will likely making some slight calibration changes to ensure the best performance with the latest production clutches. We will also be testing clutch setups with the Stage 1 and Stage 2 Exterminator Kits to make sure we are taking full advantage of the increased power. Whether it’s a stock machine or a fully modified race machine, putting the power to the ground is a critical part of getting maximum performance, and we truly feel we have the best in the business when it comes to dialing in the correct setup. Our Hypershift Weight selection is the largest on the market and they are machined in-house along with our custom cut helixes- coupled with the large range of our exclusive H5 Alloy Springs, we have the ability and knowledge it takes to get you the right setup the first time and eliminate the guesswork and time spent adjusting weights that might come with other kits on the market. The Hypershift Clutch Kits are available for pre-order now and will ship after field testing is completed.

Speedwerx Lightweight and L2 Mufflers have been tested, the fit and internal specs are the same as the 2012-2017 models. Exhaust pressures match the stock system, so there is no power gain or loss and performance is consistent across the board. Mufflers are in stock and available for purchase now, and there is additional savings offered if you purchase them as an option at the same time as a Stage 1 or Stage 2 Exterminator Kit.

Bored Throttle Bodies and Ported Cylinders are still being tested at this time, and may be offered in the future as part of a Stage 3 or Stage 4 Exterminator Kit, or as an upgrade from the Stage 2.

We will also be developing a 900 Big Bore Kit to meet the new ISR Hill Climb rules for the Improved Stock and Mod classes- this will surely be a stellar back country engine package as well!

Stay tuned for further updates...
