Mono skid faster than pro active?

[snowrules]

I have an 07 apex rtx and my dad has an 06 rtx. 06 has the mono 07 has the pro active. Had them out on the lake this past weekend with only about an inch of snow on the ice so great conditions for some speed runs. both sleds are virtually identical. both have 24-38 gearing, 1 1/4" predator tracks with the same 1.325 woodys studs with the same pattern, ram air lids, same heel clicker setup in the primary, both stock secondary set at 60 degrees, 06 has a gutted stock exhaust and 07 has an excell. lined them up numerous times on the weekend from dead stop to rolling starts at different speeds. the 07 will take the 06 off the line and in the midrange everytime and jump ahead by about 8-10 sled lengths probably because the pro active skid seems to get better weight transfer than the mono. but at about 150-160 kmh the 06 reels me in fast and blows right by me. by the time we are both topped out he now has about 8 sled lengths on me and his speedo is reading about 206 kmh and mine is reading only 198. is the mono skid that much faster than the pro active? and even if it is I can't see how he can make up that much ground and continue to pass me so easily. it's almost like his set up just makes that much more power than mine but i figured power wise they would be just about dead nuts even. also while doing some other testing on the same day i ended up putting his sled back to stock, stock exhaust stock airbox and he was still able to catch me and pass me this time by only about 2 sled lengths and it took him a bit longer to make up the ground. any thoughts i really didn't think the skids would make that much difference but it's really the only thing different between the two sleds . help can't let my dad keep kicking my *ss like this

It wouldn't surprise me if it is the skid that is making the difference. However the other variables that could effect the racing are; rider weight, belt ware, condition of hyfax, and track tension.

Either way, at least you'll be able to have far more fun when the trails get bumpy.

i live the same senario last winter...i have the pro skid also and i cant beat a buddy with the mono...i think its the lack of wheels causing to much friction...so during a drag as the hyfax heatup they would slow you down...low snow wheels and 4th wheel kit would even you out i think. I am installing these kits right after christmas.

Maybe you need to ditch the Excell? You said both were the same then one has a stock gutted exhaust and the other aftermarket?

Yes, but who rides at top speed all the time.... For trail riding, your sled is better. The mono does work better for top end. But, it tokk him to almost 100mph to pass you.... I would think that if you went to a 135mm idler wheel and add a couple of more sets that you maybe able to close the gap, plus still kill him out of the hole...

we both had new hyfax, we weigh within 10 pounds of each other, we both have 4th wheel kits, 3 small extra wheel kits installed on each and oversize mid and rear idlers to the point where our tracks barely even touch the hyfax anywhere. we had also just set track tension the same on each sled as the tracks are both brand new and we kept checking them all day as they broke in and stretched a bit. now that i think of it i did have a brand new belt on the 07 and his 06 had about 2000 kms on it. so maybe just that combo of different skid and thinner belt was all it took. also may try ditching the excell for stock against his gutted and see what happens. thanks for the input guys keep it coming.

What lake were you on ?
Should of traded both drive and driven clutches. Would have been interesting to see if there was any difference. I bet there is.

 

[Frozenstiff]

Your sled should have a 22 top gear. Maybe it cann,t pull the 24 ? Do you have a 23 to try ?

 

[snowrules]

it was at my cottage on sharbot lake. i don't see why it wouldn't pull the 24 it's the same motor and the 06 comes stock with a 24. just ordered 2 23 tooth gears to try gonna try them one at a time switch the 07 to 23 run them see who wins then switch the 06 to the 23 as well then retest. the 06 had a 23 tooth in it last year and seemed to run even stronger with even more top end. why do you think swapping all the clutches would make a difference? maybe something worn in the 07 you're thinking? both clutches are running the exact same weight and both sleds are hitting 10600-10700 rpm

I owned both sleds at the same time 2 years ago and same thing the 07 holeshot 06 top end it is definatly the skids that make the differance.

You just got a slow one.

 

[Frozenstiff]

I suggested changing out the clutches because it is a very easy change and will rule out any problems in that area. I think you will like the 23 in your 07 Rtx. It works well in mine. Are you running the stock 82 gram weights in yours, with the stock belt ? Have you tried the white secondary spring, @ 6 ?

Get rid of all the extra wheels on one of the sleds. Every bearing takes energy to spin. You don't need all these wheels if you are running on snow. Let the hyfax do its thing. It is more efficient than wheels.
