Be ready for the 2027 season!

Some of our products have longer lead times. We invite customers who are considering the following products to contact us before May 15th to ensure they get their order on time for next season. The products below will only be available for those who reserve in advance and before May 15th, 2026.

Products that require booking in advance are:

- 900R Standalone engine management system (MaxxECU, MoTeC, Emtron)
- 900R and 1200 4-Tec Staged injection system allowing to run pump gas and race gas at the same time.
- 1200 4-Tec stroker kit +8mm (billet crank, forged rods & pistons)
- 900R turbo upgrade with the largest unit of the industry from Pure turbo.
- 900R custom Garrett or Xona-Rotor turbo conversion kit for ultimate power.

Again, we stress the importance to reserve advance for the selected products listed above as none of these will be manufactured to inventory for next season.

New product offering for the upcoming season

1- Our MaxxECU loom will now support Staged Injection as a standard feature. This means it will make upgrading to 6 injectors and adding an auxiliary fuel system simple and easy. We have added a connector just for that purpose.

2- Our base calibrations will feature full compatibility with multi-buttons Can key pads to further enhance vehicle function management. Can key pads can be configured to control almost unlimited features such as multi-boost setups, cooling fan control, anti-theft protection, ecu power hold, data logging, etc...

3- New Turbo upgrades featuring the largest turbine and compressor wheels in the industry while still using the factory turbo housings for a clean and totally stock look. Boost pressure of over 33psi is achievable with our turbo upgrades.

4- Newly designed intake manifold featuring an all new CNC machined fl**ge and bigger runners which will come standard with provisions for 6 injectors to support Staged Injection. It will be possible to use this intake either with 3 or 6 injectors.

5- A new 54mm electronic throttle body (instead of 48mm stock) with an adaptor loom that will make it easy to adapt to the vehicle without any wiring modification. This requires an aftermarket ECU however.

6- One piece aluminum charge tube with a standard Tial Q-BOV fl**ge to be used with our intake manifold.

We are excited to offer these new products which have all been extensively tested this past season on our own snowmobiles.

PS-6 2025 Lynx build -- Turbo and supporting hardware

We have chosen a Garrett GT2860 Gen II for this build. We feel this is the best all around turbo for high performance recreational applications. This turbo is paired with a small ar turbine housing to maintain good trail manners and spool fast. The turbine housing is a Tial .52ar V-band stainless unit.

Boost is managed using a Tial 38mm MVS wastegate. This wastegate is configured with rather stiff springs with a base pressure of 18psi. Consequently, the minimum boost will be around 19psi which is perfect for pump gas. It will also support boost pressure to around 40psi assuming there is little restriction at the muffler.

The intake is our standard aluminum unit. It is modified to accept the larger 54mm throttle body and 6 injectors. Total injector capacity is 2 x 85lbs/hr per cylinder. The internal 4 bar map sensor from the MaxxECU is enabled for PS-6

The intercooler is our standard high capacity unit which has proven great in race applications over the years. It features a massive core and large tanks with cast aluminum inlet/outlet elbows. A one piece aluminum charge tube of 2.25" is used between the intercooler and the throttle body. A Tial Q-BOV is attached to the charge tube and is loaded with the Tial white spring to avoid cruising with this BOV partially open.

A sophisticated aircraft oil vent system is used to separate oil droplets from the crankcase vent at the valve cover. This is much more than a "dumb" catch can. It is a system that returns oil into the engine oil sump and lets clean positive air pressure from the crankcase exit out in the open. It is a system similar to what is often found in performance aircraft piston engines and larger turbocharged diesel marine engines.

Finally, PS-6 is set up with our successful full V-band header kit to mount the turbo, the wastegate and the exhaust downpipe going to the factory muffler. The muffler itself has been lightly modified to enhance flow -- but still remain as quiet as possible.

This complete system has proven to be very reliable over the years. We tried longer tube headers in the past and concluded these can only be considered for applications where turbo spool is not a crucial success factor. We have also experimented with just about every turbo combinations (Xona Rotors, Borg Warner, Cat turbos, Garrett 2854, 2560, 2860RS, 2863, 2867 & 3071) and the GT2860R Gen II remains at the top of our list for all around great performance and reliability.

Our next chapter will describe the MaxxECU engine management system in details... stay tuned.
