Yeah that's why I was asking how you did on snow. You must have made a bunch of runs with the snow we had.

Zero! Lol. My fuel line popped off that day, after 3 passes and had to abort.
When all the snow came I decided just to go trail riding. As now I've got 8" on the ground. No good place for me to test any further.
Sleds on a hoist right now, greasing brgs and putting in a new snub shaft.

Bare ground is not a good indicator for et's as it's about as good as it gets for traction half frozen, but it makes for great testing grounds because it will expose the weaknesses in your clutching. If you don't get slippage in those conditions you should be golden moving forward. That's the beauty of testing in many conditions, you gain knowledge and can utilize that info moving forward. Don't be afraid to test if conditions are not optimal. If nothing else it helps to get out there and go through the motions so you can develope good testing habits. You will never go away without learning something.

Well....I asked a pro as everything was considered. As he (running sub 6's) explained it would not change much, if any. As he tests on same ground situation then dragys hardpack. Possibly the slightest decrease in ET and the slightest increase in mph.
As you know, Steve...I ran on a stock 35° helix @ 2600 engagement. An argument could be made that had I had my 3800 rpm spring in there & Dalton Helix I could have really taken advantage of things. But, it is what it is.
Yes, with your assessment of clutch slippage. I had none with XS825, stock helix, 2700+/- Blu/wht/Blu Yamaha spring & Dalton B/O 80°
Note: I keep changing engagement because it's really hard to see the tach as it doesn't hold steady when I leave, on the break. But it's low.

 

[Doc Harley]

Steve, I'm explaining to guys that don't have the dough, they can run good strong sleds on a budget. That's all.
I'm just having fun, bud. lol.
Pic of spring. I'll pull it out in favor of something a little more robust. I'll get numbers on hardpack when available.

 

[Doc Harley]

Either way I'll be met with some sort of ridicule, by one or another.
I'll show numbers and someone will find a way to discredit.
I would have been in St Germain for the radar runs. But I'm guessing that's cancelled. Would have been nice as I know at least one person would have been there, possibly two or three. It'll just have to wait till next year when I'm going even faster, on a 275, 91 pump, zero Boostane, non header tune. What's funny is the naysayers won't be there. That's honestly the ironic part. Lol.

 

[Doc Harley]

Steve, You have me thinking....I'm kinda glad I didn't have a higher engagement spring in the primary. Cuz honestly that would have really tested my cheesy clutch combo. That would have went south....quite frankly.
You understand 4,000rpms with traction. Yep...haha.

Why new Stub Shaft? Hurricane?

 

[Fast]

Case in point...do more, spend less. Believe, you can do it!
To none-believers, please just keep scrolling. I can show results like these all day long.
Im just getting warmed up.
Him:6.64

me: 6.34

Is this a boost your running against?

 

[Trailleader]

not thee boost
Lol

 

[Doc Harley]

Nitro 1049 shaft, new brg, etc. just waiting on a seal.
It's been claimed to have a tighter tolerance then the 998t. We shall soon see.
It's a little risque, not as promising as the Hurricane hub. But Id like to give it a try.

Is this a boost your running against?

Stock boosts are running 7.5's @ 88mph in the 660', And I'm not afraid of the garden variety 20hp pump gas tunes either.....But I'm (we) are no match for a turned up Boost. Haha...I'm not sure if guys are paying attention or not. They are running 110+ in 500' on elevated octane, of course. They're in a whole nother league. Im just not sure of the maintenance schedule, at that level, as far as cranks, pistons, turbos, etc.
They come to St Germain to dominate (trail ridden 998t that make less then 350hp), plain & simple.

 

[Doc Harley]

not thee boost
Lol

Ya know something, I'll never have to worry about seeing a turned up Boost out on the trails or perhaps when I stop and quench my thirst.
Cuz the poor Boost thirsts for something that the local pumps cannot provide. Hahaha...
I'd have better luck seeing the loch Ness monster coming out of lake gogebic. Or perhaps a unicorn in the woods. Lol!!!

So your telling me a 998 on elevated fuel can't beat a boost in 500'

 

[Doc Harley]

Sure, it can. Somewhere in the neighborhood of 400hp 998t will beat it. Anything seriously less, and I'd have my doubts.
All it takes is money.
I'm not bragging them up!! As all they're good for is the short run. They know that. And it helps with longevity. Who in God's name would want to take a two-stroke Turbo to 1200 ft and not expect some sort of repercussion, at some point.
St Germain looks like a bust. But I'd have loved for a 998t to show up and sit back and laugh....being 100%
Cuz that's when the Boost's would just sit there and say "naw....I don't want none of that." That's a fact! Lol.

 

[Doc Harley]

Question, how much is .5 seconds in sleds lengths to 660'? Say carrying speed is 105 on top...
