Stock gearing or change it?

[1CrazySledder]

I tried to research this question on here first, but kept finding all the wrong threads. Anyway, below is my set up and I'm just curious if I need to change my gearing. I have it all apart now, so now would be the time to change it.

2007 Attak GT
MPI Supercharger running 22/26 ( 7.5 lb low boost, no motor mods yet on pump fuel)
Clutched to hit from 10,100- 10,600
9t Wahl Bro extroverts
144"x1.5" Camoplast Crossover ( clipped every third, all windows open )

Thanks,

-Vince

Gearing is not a question that can be answer with one simple "use X gear" Everything has to do with it. Questions like, how much power, how long of a distance, what kind of snow conditions, How fast to you want to go in that distance, weight of rider, weight of sled, traction avialible, clutch ratio at full shift and more. Factories give you gearing that they know you can go over so as to keep you from overreving at full shift. When stock clutches on a rx1 or Apex go 1:1 your done. they won't overdrive so the RPM would then continue to climb if you have enough power. Generally speaking the more power the taller the gear you can pull.
Attack gearing is 23/38 and is I believe a good all round gear. Tell us what you have to answer the previous questions, and what you are trying to do an Maybe someone can give you better gearing for YOUR application.

I suppose I did leave most of the story out.lol

I'm going to running around 210hp at first this season. I ride 50/50. Trail/boondocking. On the trail, I want this sled to snap my neck, I'm not much of a top end guy, I'm more of that corner to corner trail rider. I want to try to get all my power at low and mid. What I plan on doing is use the 144 for trail use and switch to a 136 for radar/ice drags. For that, I'm sure I will change gearing/clutching for the 1000ft.

I was just mainly concerned that the size of the 144 will effect something. When I change over to race.

I don't think you will have any trouble snapping your neck LOL. I have the 25T top gear and off the bottle underrevving I still thought it pulled damn nice, not as nice as a well set up 800-900 but real close. I stayed even with a mach z off the bottle up to 75mph. I would leave it stock and see how you like it.

If you were a corner to corner guy you should throw a 22/40 combo in there and give the SC to me, it will acclerate the same up to 90

LMAO.....

My next thing is adding N20 to my blower. That aught to be fun.

One step at a time here. Low boost to start, then max out the stage I, then go to Stage II maxed out, then add N20.
