plug your ported track holes

[SnoPro1000]

well i have had a 4 year old track and then ported it, and now i'm on my 3rd year yes it was once a 136 1 3/4 and now 3/4s of the paddles are missing but thats not the point the point is that it didn't rip.
Also i was riding in some powder climbing some hills i had mine 2001 t-cat 136 1 3/4 and my buddy's had theirs summit (factory ported) Formula 3 (unported) RMK (unported) and every time that we would do a climb my sled would come up and so would the summit with NO SNOW what so ever in the undercarage and the 2 others were FULL! so we then took em down the river,... were there was a good 2 feet of slush... the thick ****.... once back on land we checked it out again and imagine that the 2 ported ones nothing! the 2 unported ones FULL of slush and we couldn't even lift the back of the sled because there was so much extra weight.

Long live ported tracks!

LHF you are an idiot. if you never get stuck then you never ride hard. why dont you get off the groomed for once and try 4 feet of pow.

4 ft of pow is for pu$$ies. 5 ft or more.

I would love to see you take an XP across the water,,,,, You are going down baby....
How bad could flappers be.... lets the snow out,,, but not in... DUH!

ported tracks

plugging holes in the track..........

for those who really feel that ported tracks let too much through, put your sled on a track stand, (assuming its ported) spin it up to 40 mph, and throw a bucket of water at the track face.

How much water went through?

I saw a felker "tuned" sled this year. I wasnt blow away by its performance.

So I assume, you have had your sled on a stand & run the track at 40 MPH, and thrown a bucket of water at it.... Please tell us,,, how much water goes through.

Some? Enough? 10%? What if your sled was setting on the water?

I'd think of it this way: The track is not like the hull of a boat, it isn't being dragged across the water. It's more like the prop, and all it has to do is push. And anyone that's had bad luck changing a prop out on the water can tell you that a prop don't float.

It's the paddles doing the work/lift and not the belt. The track on a snowmobile moves too fast.

Also, if your crossing water with a sled, I don't think a couple extra holes in the track are going to make a damn difference if you stop.

I know my brother saw less snow pack on his sled back in the day... I don't know much about sleds, but I nkow I can compare it to quads

I think rotating mass comes in to account, but for general riding. Id don't think it's enough for the butt dyno to even notice...

But there is a reason why people in sand drags and hill shoots run drag cut rims and tripple buffed tires. Because when you're looking into Time by the 100ths of a second... that can mean the difference between winning and losing..

my 2 cents.

 

[GMCRMK]

So, am I ok to port my chaincase just above the lower sprocket?

I figure I'd be ok as long as I don't side hill to the left too much and if it doesn't work maybe I can just buy a kit to un-port it.

 

[John Peck]

i could just sell you the ones i cut out of my track, i won't be needing them

X2 I think your on to somthing here 89sandman.

 

[unclemark]

So does any one have pics of this MOD you guys speak of

[mandingo]

that's to funny !

i've had non ported track's , IN THE OLDEN DAYS, i've riden both , i think the ported track is better , but if a guy can sell plugs to some weak minded people so be it , i think i'll go cut up the mud flap off my logging truck , just in case . lol

I ran flappers this past season. I liked the idea, and usually am open to experimenting.

I think they probably provide a hair of additional flotation, but not a huge competitive difference.

The only issue I had is that they fly off the track, release at about 70mph on the trail. The whole flapper and rivet leaves the track. Some stay, some go.

Unfortunately, we have about 4 miles of trails before we get to the good stuff. The other ideas is you're constantly careful about loading/un-loading your trailer, and trees, etc..

While it's a novel idea, I probably won't do it again.
Many other little projects that the $$$ could be spent on.

MD.

 

[portgrinder]

To clarify, it takes 4 times the effort to accelerate or decelerate 1 lb of rotating weight vs 1lb of stationary weight.

Impress me. Lets see your derivation and assumptions....

LOL That would be nice...

I do know the less snow build up is bogus , i never see any diff
I dont know about the floatation and climbing issue , and thats my question.

as far as skid filling, i should take pics of it one day. my dads 06 m7 153 is bone stock except some cracks(silly trees) my buddy has the same sled with a ported track and 2 wheel kit. riding in the same conditions you CANNOT see through my dads skid ever... my buddies has a little buildup around the suspension parts but significantly less. so i see that as a large benefit, snow isnt all that light.. especially wet heavy stuff!

as far as the climbing flotation.... there are better things to worry about then some tiny holes in your track. like clutching. good clutching wins over a LOT of other variables very often. not the end all, but sure makes an actual gain, not some tiny holes in your track. i think most of us can agree length lug height is really where the gains are.

 

[Jakepol800]

wow

I think i may have just got alittle dumber reading this. I have ported alot of tracks and never had a problem i think i may start making a kit to make sleds heavier so the skis dont leave the ground, what do you think?

 

[MtnMasher]

Just as everyone has been saying, you don't port a track for floatation, you port for snow evacuation. Porting has always worked for me so I will continue to be a advocate. On a 154x16 track you have 2464 square inches of track divide by 2 (less than half the track is on the ground) 1232 sq. in. if it is not ported. Lets say you lose 200 sq. in. of track due to porting. Sled wieghs 540 on the snow. Sled 1 (ported) has .5 lbs per sq. in. Sled 2 (non-ported) has .4 per sq in. You guys are telling me a tenth of a pound will make a difference? MM.

i thing i may start making a kit to make sleds heavier so the skis dont leave the ground, what do you think?

maybe you can sell the idea to the same nin-can-poops who make those plugs.
