It’s an unfortunate fact that innovated products will be copied from some companies. Hurricane products have been copied many times over the years too. Patents are expensive and a short term solution because the Powersports industry evolves at a rapid rate. Many have asked me why I don’t try...

We have a full line of Xs belts instock https://www.hurricaneperformance.ca/products/power-sports-performance/ultimax-xs825-snowmobile-belt/

The stock manifold mod flows like the performance header and runs with the header flashes. The area that’s welded back together is strong and virtually invisible

There are huge gains in the stock manifold but they aren’t from port matching. If you look at the shape of the tubes as they are cast, you’ll see how far from even they are. That’s why it’s so expensive for us to port the stock manifold. We actually cut it apart to change the tube directions...

There is a very nice install

We generally will add quench in higher hp engines. In fact now we are machining the combustion chamber into a hemi dome. We are finding advantage to this

All things are possible. For us at Hurricane performance, hp is an ever expanding evolution. When we learn to make say 400hp, we then have learned the stepping stone to make more hp. That was the process that has led us to make over 900hp on the 4cyl Yamaha engine. Not we’ve learned to make over...

It targets the originally intended afr target for the flash

We plan to send the algorithms this week to people that own a Hurricane flasher

Actually I’m not disagreeing with you. That’s the beauty of closed loop tuning with an o2 sensor. Fuel can cause a difference in the tune. It’s not been my experience that the difference is as pronounced as humidity change but regardless, change is change and the only way to correct it...

The algorithm is added to the ecu through the flash so no flasher required for the Hurricane gap closed loop system to work

The hurricane closed loop will not add hp as claimed by other’s because the tunes are correctly tuned for fuel economy and hp to start with. The advantage of the Hurricane gap closed loop system it that the correct tune is maintained everyday to run as intended

The Hurricane gap closed look system is essentially a preset auto tune. We build the tunes to be safe and powerful on the cold air days. Thus the warm days make less power because there’s less oxygen to burn through the chemical reaction that occurs during combustion. The 998 has an baro meter...

That’s not my claims. I really don’t think it’s realistic to claim something from speculation

Hurricane - Gap 998 Closed Loop System The Hurricane - Gap 998 Closed Loop System upgrades your Sidewinder - Thundercat with the ability to monitor the AFR values. this upgrade allows your sled to self adjust the fuel delivery according to the climate of the day, everyday! the fuel...

You need the 3 bar map sensor to run the 270ss flash. The 270race version will run into the stock map sensor

Call hurricane then. Your flasher will be under warranty
