Just wondering if anyone with a stage 2 1200 at 12 pnds boost and a apex stage 2 running 12 pnds same traction who would be faster in 1000 feet has anyone tryed this

[SKIDOOCHRIS]

the torque on the 1200 is huge and the apex needs to turn a million rpms to make power....its a no brainier

[jshepard82]

Skidoochris is right...the apex is faster after it makes its power.

[SKIDOOCHRIS]

at a wimpy 12psi even a nytro will beat a apex

the guy who makes power first wins

...ya OK Anyone else care to fill us in on there theories ? Let's hear a few real events that actually went down. Here's mine. A 1200 running 200 HP raced me and I was running 12 psi in my apex I was so far ahead after 1000 feet it could have been about 10-11 sled lengths. We did this multiple time with the same result. We will only know next year if that extra 40hp from running stage 2 at 12 psi will put the 1200 ahead. I'll YouTube it for you guys.

X2 for what PooDoo says, All things equal, yamaha 12 lbs and Doo 12 lbs. The yamaha will walk away every day. We owned 1 of each sled, stage 3 ski doo, stage 3 yamaha, and big turbo Z1. All running equal HP settings or close to 250-275hp, the yamaha had the win every time. Now set up all the way full kill, the big Z1 @ 32lbs boost was 1st. Yamaha @ 20lbs boost 2nd and the doo @ 22lbs was 3rd. This was 800-1000' races. 1200' or more and the yamaha would have been the lead sled.

This was all on snow and our 3 sleds all had very good clutching for snow drags. All had similar tracks and plenty of traction. And the results were pretty consistant across the board. Only ran on Ice a few times, but our big Z1 was set up better for the Ice then the other 2, so that wasn't a good comparison. The yamaha would MPH 140 plus, so would the Z1. The ski-doo ended in the low 130s.

From what I have seen, any sled could be faster, just really comes down to how the tune/set up is on that given day and track conditions. For example, On real soft snow, our ski doo could beat my Z1 by 1-2 lengths, but once the snow set up a bit, the Z1 was 3-6 lengths in front. Its all in the tune!

Like he said all things equal 12psi the Yamaha always walks away. If you differ I am always open to a race and help with that indifference.

poodoo82 l dont think you have been taking your medication you are not comparing apples to apples 200hp 12 psi you do the math

poodoo82 l dont think you have been taking your medication you are not comparing apples to apples 200hp 12 psi you do the math

I was thinking the same thing 200hp on a 1200 is about 6-7 IB's boost, we have made 280hp at 12 Ib's on a MCX stage 2 kit.The thing is you can't judge power by the pounds of boost, just because it says 12 Ib's dosn't mean it's making more power then at 7 Ib's.

Not long ago on the dyno there was a apex with a one off kit on it that made 330hp at 13 Ib's of boost,not a far comparison if you ask me .

my sled @ 12psi would be about 270+hp (11+hp per lbs boost) I am trying to find my video of my sled racing the outlaw stud boy shootout at lake city last Feb
I did not film it and I got 2nd, I did not save it on my youtube page
well my boost controller hose had a hole in the line so the boost was set by the spring @ 12psi
if you saw the video you would understand how fast the 1200 makes torque = power
in this race it took 1/2 the track just for the yamis to catch up some @ 40+ psi
on soft surface you could never harness the torque of a 1200
lbs per lbs the 1200 makes tons more torque than a apex and nytros will not live near 500hp
tune...it is still hard to keep my sled form slipping the belt or spinning

how many rpms did it take to make 330 hp @ 13psi .... 12000?
and what about torque?

Firstly I was stating how far ahead I was and that I can not see at 12psi the skidoo catching up that much distance. You should read the whole post before assuming.
And furthermore I think you guys conviently missed a whole post above haha. Here I will re post it for you.

Yes Apex make around 300 hp at 12-13 psi. We see that all the time. Tourque is when you launch from the starting line. Like a 350 spinning its tires off the line WOW AMAZING then it starts to accelerate and its OK....beacuse HP is all that matters during acceleration.

[powderlites]

Torque = acceceration
HP= Speed
Power to weight?
So many things but 1200 makes big torque and with proper setup can make some pretty big HP right off the start.
Rev up the 1200 to about 8750 RPM with precision injection and Ignition timing control and it can fly.
Same size turbos we have seen very close HP numbers.
This setup with a small faster spooling turbo will be quick for 1200.

Im soory but you are wrong.
Horsepower is responsible for moving the vehicle along and gives it the ability to cruise on the highway and accelerate in normal conditions.
Torque is the force that helps the vehicle start moving from a stop and pulls it up steep hills. Torque steps in again to provide power when you're hauling items or towing something behind the vehicle.

Higher torque ratings are more important than high horsepower ratings if you pull a trailer, haul heavy loads or drive on roads with long, steep grades.
If you like to see how fast you can get from stoplight to stoplight -- or if you do a lot of other quick acceleration driving -- horsepower is more important.

here is the link: http://trucks.about....ng/a/torque.htm

TQ will get you off the line AFTER that its HP that accelerate you. Dont fight on this point. TQ help with loads restrictions but a high HP regardless of TQ will accelerate if the conditions are equal.
