Outlander slip on muffler.

[motoz/HMF]

We juuuust got the Bombardier Outlander 800 and are testing a slip on (slip on first then possibly a system) and should have some pictures and dyno runs soon.

We have the FIRST Dobeck Performance EFI tuner box IN THE COUNTRY!!!! so that we can give you "real world" results.

Stay tuned.

Testing on the dyno.

EFI machines require a different approach to tuning as carbureted versions. No more going to the jet assortment and changing a jet or adjusting a clip, we cannot write the initial calibrations for the EFI box from Dobeck at this time (we will be able to do so in the future) so we make runs, exchange emails showing power curves and air fuel readings then see where we need to add or subtract fuel and they send a new micro chip the next day. NOTE: the box IS adjustable by turning adjusters in the box but when we try one for the first time it takes testing on how much fuel you can add and where you need to start, kind of like which main jet to use. Once we get the amount of fuel needed the adjustability is quite a large range.

It was a matter of who got the machine first, but we work things out long distance. It went really well on the Yamaha Raptor 700, we made really good horsepower and were the first ones out with a pipe AND box.
I think 4~6 hp gain will be easy. The airbox is fairly restricted as to the amount of air it can pull in, modding the amount of air in will add 2~3 more hp (we can't mod this machines airbox because it is a new dealer machine).

With EFI machines we can throw all kinds of fuel at them, the problem is the airboxes are restricted as to the amount of air they can flow, this type of atv will usually find themselves close to or under water so modding the airbox probably will not be done.

Bottom line, to make horsepower you need fuel and air, without the proper amount of both power gains will be low.

I should get the new chip today (Mon Sept 12th) if so, I can post some results asap.

NOTE: the slip on IS done and should be available because the welding fixtures are done.

The Outlander results are just like the King Quad, it needs air big time.
We were able to squeeze out 2 hp with just the HMF slip on.

We got the FIRST Dobeck box in the country for testing and it showed a 2 hp gain but the amount of fuel programed in ths box was not enough, Dobeck would send out a box the same day UPS next day air.

Unfortunately, we were not able to dyno the second modified Dobeck box due to UPS losing a next day air package... FOR 4 DAYS!! The dealer needed the machine back and we were unable do do more EFI tuning.

As it stands we got 4 hp with the slip on and the original Dobeck box which needed more fuel. The NEW box that will be available to the public should add another 1~2 hp for a total of 5 ~6 hp much like the King Quad.

We are sending Dobeck Performance a slip on for testing as they have just gained access to an Outlander.
They will be able to provide us with the optimal settings for the new EFI box where we could not.


A gain of 5 ~6 hp is what you can expect to get with the HMF slip on and the new updated Dobeck box.

The key to making more hp will be modifying the Outlander airbox and or getting a free flowing air filter, it needs to flow more air, we got 2 more hp by removing the airbox cover, now you will not want to remove the cover but, by adding several holes in the top (for fair riding conditions) and adding a free flowing air filter ANOTHER 2 hp should show up for a possible total of 7~8 HP!

**IMPORTANT NOTE:
Adding a slip on/full system without recalibrating the EFI could lead to muffler and or engine damage.
Failure to add an EFI recalibration box WILL increase exhaust temperatures beyond what the muffler body, muffler end caps, powdercoating and internal packing material were designed.
Always verify any EFI changes by doing a throttle chop/plug check in all the ranges of adjustment.
Failures of this type WILL NOT be warrantable**

HP dyno run results

The BLUE is all stock as delivered. 39.7hp
The RED is with the HMF slip on, no re map.41.2hp
The GREEN is with the HMF slip on, Dobeck box original map.43.5hp
NOTE: this map was not adding enough fuel, the new box that the public will get will add more fuel and an additional 1~2 HP.
The PURPLE is whith the HMF slip on and Dobeck box original map and no airbox lid. This is what is possible with modding the stock airbox lid and a free flowing air filter. 45.1hp


NOTE: These runs were done on a new machine run on regular pump gas and the stock tires. The dyno HP results will not be what is published from the manufacturer as this is "real world" testing.
