Why do you need a turbocharged snowmobile engine?
Turbocharged engines are exceptional at elevation, as they don’t lose power like a naturally aspirated engine does as the air gets thinner. Until recently, a heavy turbocharged 4-stroke engine was the only way to mitigate that, but a two-stroke engine offers a much lighter alternative.
Where is the Turbo mounted on a snowmobile?
At the Alberta Snowmobile and Powersports Show in Edmonton, Alberta, they were eager to unveil their latest design—which shocked many a show-goer. Their TSS turbo appears to be mounted sideways in the sled. This unique pipe-mounted turbo enables the system to spool up quickly, again minimizing turbo lag.
Is there a POLARIS 2 stroke snowmobile engine?
It looks like Polaris is not interested in letting the Canadian manufacturer hold a turbo 2-stroke monopoly, as we found nine different patent documents related to a Polaris-built turbo 2-stroke snowmobile engine. If engine technology is something you are really interested in, you can find links to all nine of the patent applications below.
Why do I need to turbocharge my sled?
The most common complaint was turbo lag, which is the amount of time it takes a turbo to spool up before becoming responsive. Performance consistency was an issue due to this lag, for if you completely let off the throttle and then tried to go back into acceleration, the machine wouldn’t respond in time to be effective.
How much torque does a snowmobile engine have?
A “torque” engine today can be defined as an engine that will not vary by more than 2 HP within 250 RPM to each side of the power peak.
What should the engagement rpm be on a snowmobile?
I’d guess you should go with the Blu/Grn–130/260 spring. If you have too low engagement, you’ll have a serious bog. The 260 may affect your top-end a little. If you have the TRA clutch, you should be able to compensate with your “clicker” adjustments. You shouldn’t be engauging that high with that spring in the first place.
What are the features of a snowmobile turbocharger?
Turbocharger: The correct turbo in any application will feature low system restriction, low charge temperature; low RPM boost threshold and low exhaust manifold pressure.
Where does the power come from in a snowmobile?
This range of RPM usually is considered to be from engagement RPM to about 100 RPM beyond the point where peak power is produced. When working with engines of equal displacement, increases in power must come from increased compression ratios, higher port timing, more ignition advance, more efficient tuned exhaust systems, etc.
