Sorry for the late reply gents, for some reason I don't always get an email when a reply has been made. I'll answer your questions, but only to an extent as there are plenty of other turbo kit manufacturers on this site and we're not about to divulge all of our secrets. We've worked hard to get to where we are with this sled.
If you are turboing a 600 you don't need very much extra fuel to be added into the motor because the etec injectors will flow almost enough fuel to handle the turbo with out secondary injectors. now when you get to the 800 making close to 215 hp it is a diffent game.
Almost enough isn't enough. Even if it's just a little bit more fuel needed, it's still extra fuel. We built the kit to be low boost our of the box but we built the fuel system to handle higher boost levels the end user may want to run further down the road.
What was detonation like? from my experience you can't add alot of fuel into the motor through the expansion ports because the squish band in the head is to small and if you take out material in the sqwish band then the flame will be to close to the piston edge and cause problems
We didn't have any issues with detonation in our testing. The factory detonation sensor never gave us any trouble.
what was your fuel mileage? Why own a etech turbo if you fuel mileage is is going to be the same as a carbed xp
Let's not forget the power and tunability that can be had with a direct injection system over a carbed setup. Improved idle, easier starting, and better oil efficiency are other advantages. Now our fuel economy didn't exactly suffer immensely, but one would be foolish to expect any turbocharged sled to get incredible gas mileage. We all know how people ride turbo sleds. However if you were of the mind to conserve fuel on your ride you wouldn't have a hard time doing so. Remember, our turbos actually use 100% of the exhaust energy unlike conventional turbos. So efficiency is a top priority with us.
Is your controller able to add fuel with the etec injector or is everything still just a stand alone system? because if you can do it with the etec injector you are way out in front of anyone i know of.
Our system stands alone leaving the factory fuel curve intact. However we do pick-up where the factory system has it's lean spots as well.
how many miles did you put on that sled? i am having a hard time with fueling the crank talk and hoping that it will stand up with out premixed fuel.
As much as we possibly could.
who is your factory go to guy? there are some big names that have been working on this with no help from brp because of the EPA hold on the factories
I don't think they would appreciate me spreading their name all over the internet. We have a deal with them as we make turbo systems for various BRP products.
are you reflashing the ecu in any way to take fuel away from the bottom end?
Again the stock map is completely intact.
what elevation were you riding at?
Right about 9,500ft
