G4 approach angle

[xmrider]

Any body out there try too drop and roll a new g4 and put a 8 or 9 tooth 3" pitch driver on to try and cut down the nasty steep approach angle they come with. I See they only make a 6 tooth 3.5" for the newer tracks which is about the same size as the 7 tooth 3". Would defiantly help with getting up on top. Not to sure if a different skid would help at all. Any thoughts?

I really don't know why BRP continues with the steep approach. It dose sound like it would be an easy fix for them. I have seen the older sleds have the skids pulled back and a longer track added. This reduced the angle. Just risk throwing more weight on the skis by doing this.

I really doubt that a 3"pitch driver would work on a 3.5" pitch track..
Trust me, I am sure doo experimented with low attack angles.. with a 3" lug you won't lose flotation, the low attack angle is old school technology. I myself think you would get better flotation with a sharper angle, because you push on the snow more agressively downwards..

I think your overthinking it, Not necessary and to do a drop and roll would be a waste of money on these new sleds. Track technology has improved huge with the deeper lug, bigger pitch, and lighter weight.

Im pretty confident that a stock summit would out perform a full mod skud in 4ft of powder.

I realize a 3" pitch would not work on a 3.5 track. Was seeing if someone switched back to a 3" pitch track so you could run a bigger driver. The new set up on g4 definitely works good. But when you look at the new mountain cat that has a bigger drivers and a lower approach angle that definitely improved that sled and chassis.
I have first hand experience that the cat does get out of the hole better in deep powder. That is comparing a 162 3" and a 165 3".

Its becoming a popular mod to go back to a T3 track cause of the durability issues with the 3” 3.5” pitch.

If low approach angle is old technology, is a high approach angle new technology? Maybe it's a product improvement?

I don't think so, I believe Doo just thought throwing a big track at the problem would fix everything.

We need the Freak to sort this out for us.

Come on Ken, you have been around long enough to know the answers. All my experience and knowing others that build chassis says the more gentle the attack angle the better. Please enlighten us with your knowledge.

I sold a bunch of Tom's Powder Wedges for the XP's that filled the space at the front of the rails. Many, many happy customers vowed they worked. They may have worked more by stopping the tracks from bending backwards into the void space rather than changing attack angles. 6 guys in Saskatchewan even lake raced back and forth after moving them from sled to sled and they all said they picked up top speed too. Now we have 2 things to consider, attack angle and secondly if the track is buckling into the void or not. Remember on power the track is pushed into the front of the rails and if any slack, it would buckle right there. Imagine riding into a big pillow of snow and a gentle angle and the track would climb but a steep angle and a cupped shape of the track encountering the snow would be like hitting a wall.

I think you may have missed the sarcasm in my post Chris. Yes as we all know a gentle attack angle will help the sled climb better as the sled will "plane" up onto the snow better. I think what BRP's thinking on the aggressive attack angle we see on the G4's is to keep the ski's lighter and up for guys like you that go hide in the trees and hit everything you can. Lol

It even mentions letting the limiter strap out abit for deep snow in the owners manual.

If Doos thinking was to keep the skis in the air then they hit a grand slam home run on that!hahahaha

The straps are let out more than enough out of the box. Sled wheelies far to much.

They have straight rails now! Lol

Might have been a better idea to work on the attack angle. Personally I like the idea of a tipped up rail in the rear. Keeps the sled feeling like a shorter version amd backs up so much better. I expect the flat rail will improve traction slightly.

 

[snochuk]

I thought the steep attack angle was better for cutting in when starting a side hill.
Also better to turn out with when going down hill of which the G4 does well.
But that was the extent of the advantages.
Down side of coarse was the trenching on takeoff, just general trench all the time.
A balancing tradeoff???
Still climbs really well just trenches a bit.

 

[CUSO]

and what problem is that?
The sled handles well has good power and flat out works. Low approach angles have their own problems. probably outweigh the problems of a higher attack angle..

I don't think so, I believe Doo just thought throwing a big track at the problem would fix everything.

Kenny. I put a T3 174 in my 18 G4. Big drivers
