Jeb,

I Still have the original PDM kit in my MXZ, except for the Secondary I have a Red Dalton (205-310). Long story short I put that in when I was chasing over gearing with a 150storm track. I got rid of the Storm and now have a 1” Rip2 (135 studs) with 27-46 gearing. Finally got it out today and got it tuned in, pulled ramps 8 times switching weights. I use an XS821 and ended up with 2 1.3’s in the heal and a single 1.7 in the tip.

Hard pack icy trail, pulled 7900 good with this setup, good backshift but an occasional hiccup (nothing serious, might have been icy conditions). Specifically it pulled real hard up top, 114 on dream meter with more left (trail riding in woods of Vermont not many HUGE straights). I am very happy up top with the grunt but It doesn’t have the snap down low I have had in the past with other gearing and clutching setups. 

I just pulled the trigger on a set of PDM2's, better bottom 1/3 of ramp pull and rpm? I originally thought between the Red Dalton and my taller gearing was causing the Laziness but it has been brought to my attention it's the xs821.
Now you have me interested in trying one of these belts. I stopped buying $200 571s because I only get 700 miles out of them and then I am dealing with fade, sled has never blown a belt though.
Any updates on WBB?
Sounds like the DBS would be a sideways move?

Thanks, always appreciate your feedback

I believe the dsb would be a sideways move, the wbb383 would be very responsive, it is a hard belt but when squeezed properly runs a fraction cooler than the 571. With 1.1 magnets, and stock sled with pdm 2s I had a really nice shift, super responsive with 4,1,4,3 with 25/45, with 26/45 I pulled the weight out of 2. I think you could also easily go to 190 305 secondary with it and still have great response and backshift. Sorry, no longevity data other than it has held up to about 40 runs from a dig and looks just fine.

Is the WBB383 and WBB383-Snow the same belt? I can find lots of WBB383 on ebay but no WBB383-Snow

I have 200 lake race miles on the WBB383SNOW belt... definitely a good belt. VERY VERY consistent.

I would have to second this as well. most consistent belt I have used. Not happy with trying tune to 571's, 391's are down to only 2 new so I spent Friday afternoon and Sat am data logging 571, 821, Gboost wbb383, and gboostdsb383. 

571 was over loading a little out of the hole and perfect on top, 821 needed -4g from 571 as did the gboostdsb383 but both loaded way to hard on bottom, would need a higher secondary start to make them work and I am not interested in that.

The gboost WBB383 needed 2.2g more than the 571 near the base and was quicker in 330, 660 and 1320, .4 quicker in fact and super consistent. All belts had same topend. .some of the gain was due to the launch being a little low with the 571. The gboost also ran the coolest of all the belts tested. temp was from 0f to 10f and all runs were were repeated on a firm well packed track and a softer snow track. No ice or fast conditions. Awesome belt if you have the options to load properly.

Did you get a chance to check the measurements on either Boost belts compared to the 571, length/width? How is the fit otherwise?

Grover,

 

fit is good same width and 441/4 vs 571 44 1/4 to 44 1/2. 571 are too long.

Posted 26 January 2021 - 01:17 AM

I have a completely stock mxz 850 tnt (129") with the 1.25" rip saw with 90 picks down the middle. I bought it used in August and have not run it yet due to lack of snow.  It has a 531 belt on it that looks it should be changed. I suspect its the original belt since the sleds got 3700 miles and the previous owner says he never blew a belt.  Should I buy a 571, XS-821, or one of these G-Boost belts?  I care about the best performance and not so much about the price.  I don't really want to change anything except the clickers.  Also, I do plan to buy the clutch vent upgrade kit since the 2018 was not vented and and I want to keep the clutches cool with this new belt from the get-go.  Most guys on here have renegades which not only have more track and weight but are geared different.  Because of this there is not really a ton of good info on this site on what worked best on the 129" sleds.   Thanks
