998 Winder Weight Reduction

[sideshowBob]

Lite weight?
141" X-TX LE with an Earth X battery, header, lite weight drive shaft, cold air intake with under hood ducting removed, one ply Back Country 141 x 1 3/4" 43lb track, and that's about as light as a Sidewinder gets without spending mega bucks.

How do you save 25lbs moving to a longer skid?

If you're refering to the 141, they were lighter as far as I know, especially the one like I had with fox floats.
Even without the floats, there's one spring at the back compared to two torsions.

No torsion springs, fox floats, less wheels/mounts, less shafts... I'll post pics of both when I get the 141.

I have had my 141" skid out of my X-TX a couple times but unfortunately I never weighed it but it is def the lightest skid I have handled since maybe my 121" 1990 650 Indy.

Reverse delete maintaining the stock jackshaft is 4.22 lbs, eliminating the actuator motor is another 2.38lbs.
BDX lightweight driveshaft 1lb.
BDX lightweight rotor 1lb over snopro vented rotor, 2.5 lbs over solid rotor.

I've eliminated 7.5 lbs of rotating weight so far.
24 lbs of static weight not counting my side exit exhaust. Expecting to lose another 25 lbs going to a 141 skid. My 137 skid weights 67 lbs. I'll know more in a couple weeks when I pick up my 141 skid.

I took 33 lbs off my Pro-Stock 800 one season. 10 lbs of rotating weight in the cleated track alone. Went to Titanium cleats and studs. Didn't pick up even a hundredth of a second in 660 foot! Man I spent major bucks to lighten it up only to be severely disappointed. I often wondered if the titanium cleats caused more drag, so I had them coated where they slid on the hyfax, still didnt pick up a thing, then I polished the titanium, still didn't pick up even a hundredth. I built special brake discs and ever thing over the years, more often than not they exploded so I quit doing that too.

Lol!
When I was snow dragging my 1995 VMAX 4 866 Mod I had the sled on a serious weight reduction program trying to make it as light as possible.
One thing I did was build an ultra light all aluminum brake disc and at the end of the first race it spun on the jackshaft when the brake was applied and jammed against one side of the brake calliper...not good! I scrambled in the pitts hammering it away from the pad and finished the day with no brakes.
There is good weight and there is bad and the SW doesn't have a lot of "Bad Weight".....except maybe what we riders have!

BDX lightweight driveshaft 1lb.

Be careful of those with a tuned sled......

I picked up my 141 today. It weights 17.84 lbs less than my 137.

Both were weighed without the rear axle and rear wheels. I've managed to shave off 50.59 lbs, 7.84 lbs of that rotating weight.

That 141" X-TX skid is relatively light for sure and also makes a great skid for snow drags but probably too much weight transfer for high traction drags with studs ect.
I always suspected my 141" X-TX was probably the lightest SideWinder.

I had a quick look at the parts catalog. Is it only the older XTX that has this much of a weight difference? The newer ones have torsion springs, longer front arm, one less shaft (no front slide action) and what appears to be the normal shocks. The older ones had the same longer pivoting front arm, but float shocks, no rear torsion spring, and it appears to be one less shaft in the rear. The X-TX rails seem similar across the years with much more empty space (more holes, less frame) than the comparable LTX rails.

 

[DMCTurbo]

Just realized I didn't have all the pieces on my 137 when I weighed it. 59.34 lbs without the rear axle and wheel. Meaning the 141 is 20.73 lbs lighter.

 

[earthling]

wow, does that include shocks?

Yes
