Big Boost on the Pro?

[EZmoney]

My prediction is the Boosted Pro Climb will make more power, DUH, but the Boosted Poo will still be the boondockers choice. We will find out here soon.

For those of you that dont know Sam, he kinda bought one of each

Heres a question... How much better did the 2009 m8 run than the 2010 with the same turbo kits? Yes there was a hp difference in stock form, the 2010 had more compression . But after the turbo, was there a substantial difference? Just currios to here your thoughts.

Well you should have ran one last year to be my guinea pig lol.. I will start out a 8 psi and get the fueling perfect and learn the sled and then move up to 12 psi and then keep going from there. But like i said we ride at 4000 feet to 6000 feet at the very most. So i will be making a bit more hp at out elevation rather than the 10000 feet Sam was talking about and hp breaks parts not so much boost. Sled should be in and the kit will be here in about a week and the snow is deeep.

You are right there is a big difference at elevation. I bet one of these at 5000' and 12lbs would be a ton of fun! We don't get to our riding area till around 8500'
It sounds like I am still weeks out on my kit so let us know how she runs once you got it going'

You hit the elevation thing on the head. We start 10000' And go to 12-13000' Talk about a power killer!! If we had sea level HP we would probably be happy

That's why we can run almost twice the boost and get away with it.


Hopefully will know something on the Poo here in the next week or two.

Isnt that about the elevation of another sport..
I think the highest I have been is around 10500.... I could not imagine 13000!
I know that I loose about 1lb of boost for every 1000' of rise. So if I am at 12lbs at 8000' you need to run 17 +/- to be comparable......good lord I couldn't even imagine what a stocker would feel like up that high!

Im in ak, we start at sealevel and ride up a couple thousand feet, So essentially I could run 4-5 lbs and it would feel like your 12?

Yea, you ought to see ME try to breath at 12k.

The elevation not only throws a kink in power, but also tuning. Travis and Garr came out and tweaked our OVS 8s and 12s. They scratched their heads for a while. They got it figured out though.

Oh, a stocker???? Well let's just say an 8 at 12K feels like a 500 at 8500.

Yep sleds and riders alike run much better below 10k. rode with a guy from Phoenix last weekend he was sucking wind at lunch walking around his sled.

sleds dont idle well or go into reverse all the time at that elevation if your TPS is on the edge of the adjustment tolerance it casn make for a bad day. Take the same sled to less that 10k ft and it all goes away. My old 900 would foul plugs like crazy and run like chit at wolf creek same sled at 5500ft was hard to keep the skis on the ground.

Yes it would. And that is cheating! I dont know how but it still is......

Also in Alaska, My riding buddy runs his M8 at 11 lbs. with no problems, only lost a reed last year.

I know my Apex gets pretty hard to keep on the snow at 18 lbs. and 3000 ft elevation.

Good fuel is a must.

I had one of each (09 & 11, same cutler stage II) the 11 is a bit snappier, and seemed to make a tad more power at lower boost (like 11psi on both) but at 14-15, the 09 ran a tad stronger & the 11 hit the det sensor quite a bit.
Did the 12 flash to the 11 & it no longer hits the sensor as much, big improvement.

Interesting discussion about boost levels, there's really some big differences in what people run. I run 12-14 most days on both of ours, and have a few buddies who run 14 most days... 14 seems to be the limit of where people have been comfortable running on a daily basis on most of the sleds I know (RG BD & our Cutler II setups) I think the IC BD setups are capable of way more, but 14+ feels somewhat out of control when it ramps up boost, at least on my sled. My wife had the option, and most of the time she chose 12. She felt that 12 psi was a level where she could get out of anything, but when it ramped up it was a bit more manageable.

Anything above 9 is a good sled imo, but the fun really starts at 11. I would never get a kit I couldn't run at least 9 or 10 with. (at high alt I mean, I ride at or above where Sam rides... I'm sure 7 is stuperific at sea level!!!)

I find it crazy not many people have ran more boost than 12lbs. I wonder if it is because this chassis is new, and people just have not had time to try things....
QUOTE]

Nope, its because its not needed in 99.9% of riding, at a true 200 hp I can take the sled anywhere, granted i'm not trying to climb a insane chute at 100 mph but in all honesty 200 is more than enough. Why push something to near breaking when there is no reason to? Yeah when I drove promod i'd push till the rods came out, but thats for $$$$.
I'll even go futher and state that there are many times when the power will in fact hurt your riding, i'll take ya places where it would be suicide to pin it..lol....just like any form of motorsport you never want more motor than the chassis will control, smooth is fast. Yeah power is fun but give me a well balanced perfect set up 200 hp any day of the week. IMHO

LMAO! I have had 300 not be enough on some days. You can tout your riding ability all you want but there are days when too much is not enough!
And I have also never had too much power that it would hurt my riding. I know how to work the little flapper on the right handle bar called the throttle.
Some days it is not needed no doubt but, I want all I can get on all the other days....

What sled was this on?

 

[2XM3]

to each there own.... it all good.

i was wondering that as well.....300 hp ?? gotta be apex at 650 pounds

 

[JSCC]

Apex, Nytro, M1000. Pick your flavor.
It always cracks me up how people that don't ride Apex's talk so much smack on them yet sit and watch all the videos of guys riding them....

No ones talking smack, the simple reality is power to weight ratios.

200hp in a 435 pro = 2.175lb/HP ----> like a butterfly on top of the snow

300hp in a 650 Apex = 2.176lb/HP ----> like a heavy sled plowing through the snow.

Read all over the forums the pro get on top of the snow... maybe i read the wrong threads but i havnt heard the same about apexs or nytros.

The Pro dosent need the same HP to get places like the sleds you listed

This is true and I realize that. While my arms are not scales my M1000 felt lighter than my Pro moving it around in the shop and while riding. It was far from stock though. It ran with my two four stroke turbos with 2 lbs less boost. Not that big of a difference in all out power.
Someone saying that you don't need anymore than 200 hp and what not is ignorant. The same argument has been done for years yet here we are talking about turbos and what is too much.

By the way you're comparing dry weights to ready to ride weights.... Pro weighs 520ish ready to ride.

Haha caught me,

Just saying the pro dosent need the horsepower the other sleds do to do the same thing

fyi had a modded Apex for 3 years ...put over 6000 miles on it.

no need to get your panties in a bunch and start with the name calling.
Anytime you are up this way shoot me a pm and come ride with us, if the snow is good we have some interesting places to ride bout 15 min from my house, plenty of room to bunk as well.
