Racing snowmobiles is like Golf .. In golf everyone thinks they play faster than they really do.. In sled racing everyone thinks they are faster than they are… Lots of claims of the latest and greatest and sometimes they are true but most of the time they fall short of their claims.. If they Spend enough time testing and throw enough money at it and sooner or later they will run right by you… as they should… Old saying goes, nothing last forever . Hopefully we get some winter and some ice to sort it all out… Gotta love the sport to be reading this … lol….

It really, really, really is all in good fun. At least for me.
I like going over on Polaris & Skidoo groups and see what's going on with them.
Mostly Amazingly honest people in most of the groups.
However, you are correct.. marketing runs rampant, as to what's real & what's blown out of proportion.
However, we were enticed with the same dream. Lol.
And it's like you say, as we get closer & closer, we shall all find out what's what.
All we can do is dial in our sleds the best we can. If you take a beating, my hat's off to the guy!

So the only two changes I've made this year is the gap innovations Ram Air & a primary spring change.
If you decide to do this mod take your time with the Dremel and clean some things up, for a better fit.
So I'll be switching the tune 250/275/290 to verify my findings. Is the extra boost worth it?
I'm not saying 290 is not quicker than 250. But is it worth a tenth of a second, 5/10 of a second, in the short run (660) Then I'll move on 1,000 foot runs.
Most 850 two strokes like to keep things short and don't like to stretch their legs like we do. Lol.

With everyone's help here I was able to prove to myself that a tune and good traction can go a long way (6.34 660'. Could be worse lol)
I don't really care about going faster, I care more about doing things efficiently, and run straight pump gas, no Boostane. With that said I'm heading forward. Was able to purchase everything you see here + gap ram air... Very very thankful... I want to nail down mpg as the sled is today, then pull the old switcheruski ASAP.
At that point I'll get back into draggy runs @ 660' & 1,000ft

Was able to purchase everything you see here + gap ram air for less then what it costs to purchase a new TD gen2. (TD gen2 header used w/200miles) Very very thankful... I want to nail down mpg as the sled is today, then pull the old switcheruski ASAP.
At that point I'll get back into draggy runs @ 660' & 1,000ft

Going to header tunes and utilize AFPR to dial things in.
No closed loop.
Sound good? Lol

You are 100% lack of snow in my area means no testing/playing. Family crisis is keeping me grounded from heading north.
