When you drop 30k on a sled I don’t think anyone cares about a $800 track...and you’re absolutely right it builds track speed

Is that your sled?
I may have drooled on it a little.

I thought so - track speed is only good if your doing grass drags - a mountain sled needs to be setup like a tractor not a race sled - ground speed is what matters - track speed at 120km/hr is no good if your ground speed is 2km/hr - this is my beliefs

You are not wrong, depends on what the sled is built for, no point in being geared for 80mph if the sled will not build it in the trees.

Nothing worse than getting on a turbo sled, and the bottom end feels like the throttle cable is an elastic band. So called turbo heads are very bad for that.

That can be fixed - powderfreaks head - gear it down to a 2.64 with a Tki belt drive - 10" big wheel kit - then watch what happens

Lol
2.64 on a turbo...ya I’ll watch what happens! Make your turbo perform like a stocker!! Pulling the gearing out of a turbo is the quickest way I have ever seen to make sure she doesn’t pull. Dave obviously knows this, that’s one factor active in his driver change.
Beautiful sled! Looks like it should rip

It is a beautiful sled.

Just conversation.
If a builder choses 2.64ratio and uses 7t 3.5pitch, at 1:1 ratio that sleds final ratio is 70mph. With full OD at 84mph.
Properly setup, a 250hp kit better reach 70mph in 2ft of snow depending on the riders intended application. 2.52 may be a better choice, but will it sustain that trackspeeds with the track loaded?

 

[TreeThrasher]

Gearing has to be adjusted for driver size for sure.

I have rode all of Dave’s sleds in recent years I will say he has his kits are dialed his ability to control stock injectors makes throttle response very quick the guy is never happy and always trying to make things better. His 850 climber that he does all the chute pulls on reminds me of the old M10 nytros feels like they will pull forever. Then jump over to his personal sled with less aggressive rear suspension and it’s fun to ride.

You my freind are not running the rite "so called turbo head".

Im not running anything actually. Just what I rode.

Whats the right pump gas turbo head??

the stock one...

 

[Caper11]

the stock one...

Our findings as well.

 

[TreeThrasher]

You mean to tell me that taking compression out of a two stroke turbo and narrowing the squish band caused softer bottom end?? Who would have ever thought it!!!!

 

[lilduke]

even with the stock head every turbo kit I've tried looses some bottom end. maybe they should try running a high compresion head. haha

 

[mountainsledmania]

well i can say that theres hundreds of sleds that come out of the same shop mine comes out of with the same head modification as i have, and NOT 1 has this so called squishy phenomenon you speak of. In fact the lag/burble/whatever you want to call it is more predominant in the motors without the head done. But im no expert.

What shop is that?

 

[mountainsledmania]

It doesn't matter what shop it is, im not here to endorse one shop over another. Im just simply saying that it does in fact help which is why alot of the big reputable players are doing it. Boondocker for instance is a great example of this with their specifically designed "idaho whatever its name is" head. same thing.

 

[oler1234]

bottom end bog or squish throttle is general a sign of poor mapping. A lot do not use enough data points to plot a proper fuel map. The bottom end of the rpm is very fuel sensitive.

That is incorrect. The stupid “Idaho” head and the “give me” head were a band aid fix for crappy running setups. Bd fkd up and charged customers to fix there own f up. Put that in yer pipe and smoke it. Haha

Im assuming you have some sort of evidence of yours claims?

This was an old Kanedog Bureau of Investigation(KBI) case. It was many investigations ago. You missed it.
