2018 ARCTIC CAT 800 CTEC DYNO TESTING
Just settling in from another successful trip to Jaws Performance. I can't say enough great things about Greg and the crew up there. They are some of the most welcoming, knowledgeable and passionate people I have met. This trip we dyno tested Backcountry Addicts 2018 Early Release M8000. We rode this sled last winter putting 7 hours on it and it did not dissapoint. Due to the high population of keyboard warriors these day Im not going discuss peak numbers. A dyno is a tool, none of which read the same so the important part is to talk about power gained over stock.
DISCLAIMER: Results are preliminary. More testing will be done in a colder temperature environment.
We started out by flow testing the stock pipe and can on there Superflow flow bench. Both the pipe and can flow tested the same as the Suzuki components. We then made several box stock dyno pulls. Most pulls averaging 30 seconds or longer at wide open throttle. After establishing a baseline we began to tinker. The first test was to elevate the hood allowing for direct airflow into the engine without restrictions. This was educational. By lifting the hood we picked up 4 hp consistently. Keeping that in mind we continued on after installing Jaws Big Shark kit for the 2010-2017 Suzuki engine. With some adjustment to the fuel mapping via a boondocker fuel controller we were able to pick up an additional 7hp. Greg, being as determined and passionate as he is wasnt happy with this knowing the same pipe combo produced 10hp on the Suzuki motor. We removed the Jaws pipe and sent it back to the fab shop where they made some adjustments to stabilize pipe pressure. The pipe adjustments were successful. We were able to pick up an additional 3 horsepower with the new pipe. Slight fuel adjustments were made to maintain a safe air fuel ratio. The pipe pressure stabilized and we were able to make several 30 second+ pulls at WOT. Now that we were happy with the 10hp increase from the Big Shark Y-Pipe and Pipe we went back to focus on the airflow. We installed Greg's airduct which was developed for the 2012-2017 800s. The airduct directs and accelerates the flow by providing a more direct path with less resistance. The next few dyno pulls were with the hood installed along with the NEW 2018 Big Shark Pipe and Y Pipe along with the race can. The air duct was once again a sucess! We gained back the 4 hp that we identified earlier in the testing. This made for a 14 HORSEPOWER INCREASE OVER STOCK! You can bet we were pretty excited! Thats IMPRESSIVE power from a few bolt ons. This new engine paired with this new kit is going to be a hot setup!
Tech notes from this trip:
* The Y Pipe on the CTEC has a different bolt flange from the Suzuki motor.
*For peak performance the aftermarket Suzuki expansion chamber pipes SHOULD NOT BE USED ON A CTEC.
*Suzuki and CTEC mufflers (cans) showed no noticeable difference.
*Testing was done at sea level
Thanks for reading and hope for early snow!
