Shhh don't tell anyone...

Chadly where are you getting your info/measurements from? You are saying the tunnel on the 155 is only POINT 3 of an inch shorter than a 163? That doesn’t sound right at all. I was thinking 3-4 inches? Same with the doo. Can you measure the tunnel length on both sleds from a fixed point that is the same on both sleds?

His measurements are in Tenths of a foot.

Both my 840s are identical set ups minus the tunnel length. One is a 155 and one is a 163. The 55 has a .3' shorter tunnel. That's all I was saying and telling people it's probably not worth the cash to turn a 55 into a 63. And yes I think the Doo Expert is over priced and feel bad for the guys who paid the extra to get one. The Doo 54 has a .4' shorter tunnel than the Doo 65. I paid 14,300 OTD for my Doo 65 and I have heard the expert has been going for over 17,000. Not worth the .4'if you ask me. There you go for useful information. What are you even doing in this thread? Shouldn't you be giving bad advice over in the Doo turbo section???

That’s nice you don’t think it’s worth doing.

Shouldn’t you reserve that judgment until you actually ride the sleds?

Otherwise it’s just babbling..........

From the 100k worth of junk sitting in my shop ?

How many little marks is that? Probably why he posted the tape measures so somebody on here could convert it to English.

I just measured a 163 and 155 tunnel. 163 is ~3" longer then 155. So... take that for what its worth. Lot more then 3 tenths.

Couple the 163/155 build with a shorter taller bumper like BM fab and you end up with a huge reduction in drag.

If you only used 30k worth of tunnels to derive that your data is insufficient. You need 100k worth of tunnels.

0.3 of a ft is more than 3". Regardless, this thread is silly. Thanks for the call back btw.

Chadly your getting slaughtered here.

That tape measure makes my dyslexia apparent to me, which as a millennial, I must say that I'm now offended. ❄ That mess mixed in with this expert skidoo talk baffles me. Judging by the fact this is the polaris forum, I thought we were all in agreement, that any skidoo purchase is silly! In a vote for theater-leader while playing nickelback "greatest hits" kind of way, ?+☻×TWO TIMES=■¿ ??‍ dang commies...

I expect better, harder hitting meterial out of a 100k shop, or at the very least a consecutive, proper, tape measure!

I am getting slaughtered because people don't know engineer's scale? Interesting...

That’s not the reason! ?

It’s .3 FEET lol. Never seen anyone measure something like that. Ditch digger math. So it is 3.5” shorter tunnel on the POO 155 against a 163. I want the portion of my life back that was stolen by this thread.

 

[sno*jet]

ironic thing is Buradnt made a video about shortening tunnels and starts a big craze, and Polaris is the last to actually make a short tunnel.
carry on

Tenths are used in excavation. One Tenth of a foot is 1.2" so 3 tenths is 3.6" .. Metal fab is right.
And big wheels cause big Damage in my experience. BUT!! .. a big wheel offset turned backwards and Assault/Khoas Rail length will put a 163 on any 155 for minimal expense. But I'm not buying a Skidonky to compare so I leave it to the "Experts"

Might not work but we ran 151s on 144s for years like that . With Triples too !! We was modders !!!

There Must not be a bunch of construction workers in here?

 

[turboless terry]

I work construction and also use english. I can convert the figures if needed. Don't cut house studs in tenths and nobody measures tunnels in tenths on here. Barking up the wrong tree here.
