Im 240, I can do the hop overs but i gotta say.... i dunno if it could do it without a turbo in deep stuff. theres just not enough ponies there.

Im 230 and I can do em on a stocker. But turbo probably would be fun.

Have you factored the speed and power of added pedal stepping into the equation? What if you have 72km/hr track speed, a 85% traction ratio, a 225lbs dude pedal stepping at 30 steps per minute with 500 newtons of force on each super gay pedal step?

track speed is king... always has and always will be. It takes power to turn a track at a higher speed.

going 3" makes up for the lack of track speed when you don't have power

now following someone with high track speeds can be tough when in the rough

OP, what's the reason for even having a turbo? Don't like warranty, reliability, and consistency?

Also Caleb Kesterke is an animal and I probably have never seen anyone ride as hard as he does.

I’ve had a camo x 2.5, a conquer 280 and a camo x 3 all on the same sled and have put around 3000 boosted miles between all tracks.
He’s my thoughts.

2.5 great track in low/ hard snow as the lugs don’t fold over east and if your towing a dead sled out once you get on a hard pack trail it will pull so hard u will f**k your vei tunnel brace / bumper (pic below). Track speed is crazy fast and I’m not worried about it flying apart when it’s spinning at 80 mph trying to shake it down further in the trench to get some traction.

Conquer 280 light weight track good for going fwd. shoots snow chunks 200 ft behind a sled with a snow flap. Horrible for stopping out of control going down a packed hill. Fairly weak track as I hooked a small stump at wfo and the track blew out the back of the sled. ( pic below)

Camo x 3
By far the best track I’ve run goes like h*ll stops good. does not shoot chunks out at the ppl following. Tough as nails. I have not rode low snow with this track yet tho had a very good year last year.

Baddest 5lb turbo sled is easy and it will rock.
Let's use my 16 xm NA 174 3" as a kind of template if you will. When using this combo, with the exception of the primary clutch and hood, you must must must follow it exactly. The components are a result of 3 years of testing, over 100 changes, tons of parts from all over the country and now I finally can beat turbos in deep snow. The combo is very sensitive to small changes in components so the more you stray from the combo, the worse it performs. It will still embarass 850's but we need to stay in the beat the turbo zone. Oh, don't listen to the doubters. They think if they haven't done it, heard of it, seen it or thought of it, it won't work. Haha.
16 xm NA 174 3"
Dynoport ypipe, ceramic coated
Stock pipe ceramic coated black
Thing cooker can, ceramic coated
Diamond s mesh hood
1.5degree added timing
Tra7 clutch
9.65g, yes, 9.65g pin weight
105/390 Duane Watt TRA Red spring
441 ramps
Stock arms & rollers
Sheaves cut to 14 degrees(you must machine the bottom of sheaves to achieve full shiftout).
Paragon 6 pack, 52/42, silver spring(90/200)
Custom 23/80 belt drive pulleys using tki kit
Mitshobishi 1250 length belt i think
Machine chaincase to fit bottom pulley
8t powderfreaks drivers
Driveshaft w/drivers trued on lathe
Razorback belt temp guage.

With some effort, this combo may work for other 2 stroke brands too.
The reason this works so well is traction, traction, traction. A turbo spinning at 120km is not going 120km ground speed. It's probably doing like 50kmh ground speed on a steep and deep big chew. Here's how it works-This NA setup does 75kmh track speed but is travelling 70kmh. #'s may vary but you get the general idea. 70kmh beats 50kmh.
This combo is so crazy I really can't believe it. It beats turbos easily in the deep. It sounds nuts and I agree it sounds crazy but I dont have anything to gain or sell by sharing this. I don't think that a NA sled will touch this combo for at least 5 years I'd say.
Throw a turbo on this combo, 3" track, raise the gear ratio to approx. 2.75 area,8t drivers, paragon red secdy spring, 55/60 helix(I think)60/200 aaen green p85 spring and light weights, prolly like 60grams. I have a turbo poo and that is what I run in the p85. Put a 911 cover on but you prolly got that already. Your turbo will make other turbo guys cry.
Naysayers welcome to comment. It'd be cool to hear some comnents on this outer space combo.


You running stock plugs and wires?

Have an 08 caravan with the 3.7 in it. Switched out for some aftermarkets and definitely picked up a few ponies. Let’s keep that on the down low though.......not sure the plugs I’m running are exactly street legal.
