I would like to know the advantages of porting a track compared to leaving alone. I want to hear from people that have ported and also people that have both and whats best way to port a track?

i have an 02 mtn cat that came stock with a 144, we changed that to a 151 that was ported. the new track weighed less than the one we took off, so less rotating mass was an advantage. id not change gearing or clutching and still had same rpms available. But a negative was lots less floatation. But the track that was ported was done incorrectly and had ports on all available sections. Instead of the ports only behind the paddle configuration.
lets here some more comments and opinions!!
I ran a 159x15x2 Poo Series IV track last year, no porting. Worked well, ran scratchers with no bogie wheels to keep weight down, and it flicked plenty of snow. It did seem to hold alot of snow.
This year I have a 174x16x2.5 Camo Extreme with rectangular ports down the center. maybe 3"x2" rectangles. I didn't do the porting, bought the track used and the previous owner had done this. It still throws plenty of snow for cooling, I still run scratchers and no bogies. Doesn't hold as much snow as the non-ported track.
I don't think it makes sense for me to comment on flotation between the two tracks just for the shear surface area differences.
Haven't noticed any issues with tearing or anything in the durability department.

thats good that was a big factor to me by this summer i plan on having a m8 and i want to put a CE 2.5 on it and port it i think theres logic behind it less weight and rotating weight and it seems to make you have alot less snow in the skid/track and lets face it thats never a good thing especially when you get stuck and our tracks are filled with snow it no fun. I dont see anyone loosing a ton of flotation unless you went crazy on the porting i was more worried about durability dont want to throw $700 on a new track and port it and it start ripping.

The only reason I haven't done it to any of my tracks since my 05 is I would not recommend doing it on a sled without no-slip drivers and I have not added them to my last couple. The added flexibility of a ported track will allow it to ratchet much easier on a standard driver.
Thats an interesting point. I am running anti ratchets and an anti stab kit. I did notice some ratcheting while braking downhill when my track was a bit too loose, but I tightened it and all is well.
