Proclimb M8 turbo. 2871 or 2860?

[Wheel House Motorsports]

I also know that burandt tried running the the 2867 and ended up swapping back to 2860 because it wasnt responsive enough in the trees!

Well ****, Burandt tried it, I guess its been decided!!

I ran a 3071 on a 700 with great response.


hell, of the 2871, 3071-wg,full 3071, and aero 66. the best response, SURPRISE... was the fullsize 30. BUT, we must not forget, there is more to a kit then just the turbo. it all has to be working together to make power well.

as for tight trees and throttle response.. its sorta all i do. have a hard time keeping people riding with me because of the nonsense in the forest i like.

I think I need to come ride with you and just let these guys run there mini kits because they obviously don't get it.
But really, what your doing is every bit my kind game!

Your supposed to forget all of this info so our secrets dont get leaked out!
come on now

doesnt matter!! lol, i can tell people the answers and they dont listen. dont even have to hide the secrets!!

 

[WyoBoy1000]

The best place is in plain sight! My best secret right there.

 

[Crusty82]

So..are you guys saying if I would replace my 2860 with the full 3071 on my BD kitt I would get better throttlerespons and better top end?
Or do I need to make other mods to the kit asweel to make it work?

 

[WyoBoy1000]

I think I would start by throwing away the whole BD kit, I'm not sure but I don't think any of it is up to par with what would be needed, not even sure if its up to par for a 2871

 

[Crusty82]

Okay..
We are alot of guys up here that are really happy with our BD kits at 10psi. But I would sure like to learn about why BD isn't compatible with a bigger turbo.
I will rather not use another kitt than BD. Mainly because of good experience with BD, and that we are so many up here that are getting familiar with the BD electronics. It's easy to share experience. Also, the BD and rktek dealer here is very helpful and knowlegdeable.

Then stay with them.

The bd kits are the same tech other than the controller since how long ago?
They change the control, wiring harness, everything almost every time you look except the turbo??

First off the charge tube is to small, you don't need a cooler, the controller is getting much better though. The whole system is just weird, IMO the 2011 kits where some of the better ones and seemed to me stronger IMO. Not impressed with the new power on the new ones. Its just straight up different and if you don't know turbos then stick with your dealer. Its really all someones opinion unless your going to do it yourself. But almost everyone I hear from says a bigger turbo on a bd kit is worse, so the kit just isn't compatible.

 

[mattymac]

charge air box volume has a really big effect on bottom end response/on and off throttle as well! Dont just expect to throw a bigger turbo on and expect it to all of a sudden rip your arms off outta the hole!

People wonder how some of these turbo kit manufacturers get the prices they do for their high end turbo kit! Parts are a big factor obviously but theres also alot of trial and error, learning curves, R&D that go along with those nice top dollar parts!

Ive done a few small things to my impulse kit to make it even better yet! You dont have to be a 4 stroke turbo die hard to know how well pauls kits, knowlage, customer service, and him as a person to know how well his kits are in the snowmobiling world!

What are you using for fuel control

 

[Firecat162]

You guys are all so focused on turbo size, turbo flow, turbo this, turbo that and in all honesty, the turbo itself is such a small piece of the puzzle to a GREAT running sled. The AVERAGE tuner can take the best running turbo sled and in a couple rides have it running so poorly that its nowhere near its full potential. Its not even a fair playing field when your comparing Joe Shmo's poor running turbo to MR TUNERs sled. Way too many variables to make a fair comparison to one turbo sled to another unless they are built and tuned by the same guy , the same day on the exact same conditions and even then there are variables that factor in. I think the bottom line is...if you think the big 3071 does it for you...ROCK ON!!! if your happy with how your smaller turbo is working for you..RUN WITH IT! Ive had BIG Turbo sleds and LITTLE turbo sleds and they all ran great once you have the fuel,Air,Venting,Clutching,Gearing,Skid,and snow where you want it. You can flame away but these discussions have been going on for ever on this site and its still a go nowhere!!

So how much experience do you have when it comes to multiple turbo setups, did you miss the part where the ones saying run a bigger turbo are the ones that have rode both setups and do there own tuning. So it is actually a more controlled test than most other cases.
I tend to listen to the ppl that have actually done the testing and ride like I do, the ones I trust say go with the bigger turbo,

 

[Firecat162]

Like I stated above...this is a go nowhere because theres no RIGHT answer! As far as my personal experience, I think I have enough to have an opinion wether you agree with it or not. Your preaching Turbo Turbo and you dont even have one on your PC....do you??

 

[Crusty82]

Maybe there is no right answer. But I definatly see the benefits they are talking about.
"A bigger turbo will produse less heat and It will have more power on top. Even with less boost.... if setup right"
Heat is always a problem..especially with tree riding..
So if it's actually possible to keep the throttlerespons, or even make it better.. well, then that would be the right answer for me.
It's a shame it cost 6000dollar to confirm it myself
Learning alot by reading this kind of discussions keep it going

 

[Wheel House Motorsports]

I will agree, for the most part, if its got a turbo on it, i will enjoy riding it! BUT, I am a hard person to separate from my money, and I also LOVE to learn and KNOW what I have and how it can be better (read - addictive modifier) although i have a lot more time into most projects then most people have into sledding for the whole winter, I like to be able to say with confidence, X setup is better then Y. and in the case of turbos, the bigger ones are more fun.

I figure, if your gonna drop 5-6k on a kit, it should be the best it could be! Its damn fun to show up and lay the smack down on half the boost as your opponents, and have half the money into it. Some days we get home under our own power, some days on a rope, BUT, those of us who test and experiment end up with powerful knowledge you cant buy.

I asked a question you did not answer directly, what is your experience?

I don't need one on my PC to know what it did on my M, same motor, let alone I am around many turbos. It is proven. and the bigger T's dont need pointless IC's either.

Correction, more power everywhere, not just on top.

All things the same; at elevation, at 10 lbs of boost, the 2860 wins. Better throttle response and nearly identical power. Cutler's, ovs, Boondockers, etc will tell you the same. I've not tried a gtx turbo so I can't speak for them. I would give Dale Cutler a call. I've never ran his setup but he is a straight shooter and has tried a bunch of stuff in controlled tests. He'll tell you his findings. Pretty tough to beat the laws of physics. Keep in mind, bigger turbos, external waste gates, different turbine housings, etc cost more money which results in a higher profit margin. Don't let marketing make the decision for you.

Well got a good deal on a GTX 2863 for less then what a gt2860 usually is. Getting the TSS turbo kit with Boost-it fuel system, C3 belt drive with oil delete and TAPP clutch! It's all getting installed next Monday. I'll try that out for size and see how she works Sled should rock!
