Great question.
Modern 2 strokes have oilers to each high demand oiling location. I can't remember off hand how many separate oil hoses come off the pump on the Polaris, but it is 4 or 5. We also ask our customers to add a couple ounces of oil to each tank of fuel so the extra oil passes through the crankcase, reeds, and throttle bodies.
As you know, the engines make much more power, but don't turn anymore RPMs then a stock sled so the crank and bearings are not at risk with proper oiling. The death of any turbo engine is detonation which usually leads to a worse outcome and that is preignition.
We always welcome anyone that wants to ride with us. Our sleds get ridden by multiple people all winter long.
Here is a great vid of how our HO kit behaves in on/off throttle situation. This was a long steep pull too.

-Electronic Boost control. We now have an electronic boost control system that increases boost as the sled goes up in elevation. This way power and clutching is maintained at all elevations and air pressures weather it is a good or bad air day. No rider input required.
-XIC fuel controller. The Engineer that designed and builds our XIC has been building turbocharged fuel injection systems since 1980. He builds full standalone systems for automobiles and turbocharged aircraft. These XICs are built in Calgary. Even though I have begged for a standalone system, he talks me out of it every time and tells me that we have the best product out there for a snowmobile. It is easily adjustable, has unreal features, and does not need a laptop to adjust.
Have you seen the pictures of the Viper that Neil builds?!?!? That is one sweet looking sled! Based on looks it would be hard not to build one! Maybe one day Neil will build a low boost kit for a XM "hint"!

We have never turned up an oil pump, but I can not see why it would hurt anything. We like the oil in the fuel because it also lubes the fuel pump.Do you recommend turning up the oil pump as well? Or is the mixture ratio with the couple ounces cut it, even for long pulls?
At this point we do not have any intention of controlling spark timing. It would be ok for the people that insisted on running low boost on pump fuel, but as you know, retarding the timing does hurt power.Probably two of the most important points here (besides the W/A IC of course, which should never be in dispute with turbocharging)
I've looked into tuning the factory controllers quite extensively. Problem is, the industry keeps changing cal sets and controllers. Only a limited number of controllers have been cracked, and the software to manage them is just a tad bit pricey! And in the case of the e-tecs, you can't stuff in bigger injectors anyway. The boost-it is by far the most practical setup I've seen so far.
Only one question - can you intercept spark signal and substitute spark mapping?

We have 11:1 turbo heads for the customers that insist on pump fuel but have never sold one.
It seems that every one of our customers would rather mix in the proper blend of fuel.
We recommend a blend of race and pump or av and pump of at least 25% up to 7 lbs at elevation and at least 50/50 from 7-10.

Just a quick update. We have revised the pricing on our low boost kit and it is now selling for 5595.00. For those that have one on order or have one getting installed, the price will be adjusted to be 400.00 less.
Thanks...Team Boost-It
The spool time between to two is almost not noticible. The 2863 GTX is more suited to boost numbers over 8 lbs because it can flow more air.It comes with the 2860 now at the lower price, and not the 2863 (500 upgrade) so what's the real difference. I would assume the 2863 spools quicker, but on a low boost kit does it make much of a difference?
Do you ship now too, or install only still?
Both kits are capable of similar power levels. The Intercooled kit does a much better job maintaining power on longer wide open pulls.How big of difference are the low boost and high boost kits? What kind of power will each make?
Pretty sure TSS has the Etec turbo dialed in. eh Mareshow??
