For sure was just seeing if it was correct!
Well we got some testing in on the weekend, before we broke a tourque stop. Best run was as below winner on right.
Get that 60' time to a 1.45 and you'll be even quicker et
Yup for sure. Moving in the right direction anyway. Started with a 6.59 down to 6.44. It's to bad we ran into troubles.
Carbs are important, needs to be on the edge a little to be mean
2.10-2.22 gear ratio per track start
Sled should be 82-85 mph at end
64/44.75 cam or 54/40 full progressive
You will need to get your et lower.
The time slip I posted is stock 600. The lane four sled was a stock Skidoo 600 RS. Ran a 5.5 in 500ft.
I don't think he's racing the pro circuit?
Anyways, on the cosdra circuit here in Canada, no 600 has went under 5.8 seconds in a true 500 foot length track. Shortening the track under 500' does make times faster though as I've seen in years past . Can't go by what you've seen for et on one track vs the others . Many race in Michigan and New York and come to Ontario and have way slower times
Brock, I here what your saying but that is my time slip printed at Princeton, MN. It was a legitimate 500 ft by the SAME organization (NDRS)that puts on haydays. It's as accurate as haydays is. A lot of big teams go there to verify as it's two weeks earlier and only short distance from the haydays site.
Well if those are you're times. Good for you, and you obviously know what you're doing. I definitely wasn't trying to put you down at all. Just stating the cosdra circuit ran by Chris always had slower times then msdra or others.When Chris from cosdra ran haydays, the times were a little slower for those years too
I think this guy is just doing this for fun on an older model and would be in amateur class with trail studs, were a 6.2-6.4 is good and competitive. The 1.4 sixty foot time in your slip and 85 mph is what I was telling him to shoot for, and you're time slip proved what I was saying
Forged. I see the time slip is from this year. You still on pro circuit?
I used to race in Ontario, Michigan and New York years back
I don't think he is running a Team secondary is he? If so, never mind. If it is the old button still, 50-36 to start.
Those cams I mentioned are the old button style. Custom order from dalton
My rule of thumb for gearing is to gear for 15% more than you expect to reach in the race. So in this case, I'd be at 24/40. Mine was fastest in 500 feet with a custom cut straight 44 helix, Erlandson orange secondary spring, 10-64 weights tapered quite a bit to the tip to move the C.O.G. towards the heel. Maroon primary spring (185/320). Engagement right about 5000. That's what was working for me back then. If I were to start with one of those again, I'd be slinging more weight and a shallower helix. The belt and clutches would be so hot with that setup that you couldn't have handle them without gloves on. That tells me that there was a lot of slip, but it was fast that way... Also, depending on how warm it was, I was jetted way lower than you are. I don't remember specific numbers from the RAD gauge, but I often ran 158's or 160's and used the Keihin CEL needles. That sled ran sub 6 seconds many times, but usually 6.0-6.1 depending on track conditions. The real key to speed is all in chassis setup, and making sure the drive line is perfectly aligned. We spent a TON of time getting the driveshaft, chain case, and jackshaft perfect. Once we had it right, you could grab the track and give it a spin and it would make 2 complete revolutions before it stopped
That is Mike Rempel's 600 which is the fastest stock 600 in the world! Keep in mind that the 08 600 XP-RS he races is 400 lbs compared to the 485 of the XC7. FYI, I did a full tech on that sled at HayDays this year and it's 100% legit stock
I like how different combo’s but many can achieve close to the same times .
I’m just more of a lighter finish rate spring(light springs) and heavier weight to get competitive times.
