Best Boondockin Turbo

SnowSnob · May 30, 2009

It seems the best ALL around turbo sled is either the M or Dragon. I would rather do the xr1200 but until they come out with a long track and make the weight a little better it's out.
So what are the pros and cons of the Turbo M8 and D8?
I don't want this to turn into a pissing match so if you don't have any useful info don't bother posting.

It sure seems that the top dogs prefer the M but is that just because of better sponsorship? I know a TM8 won king of kings this year at Jackson but that hill comes down to rider ability and would it matter what Tapio is on?...again is he riding an M because of sponsorship?
Its sounds like the D8 handles boost a little better with the bigger injectors, I probably don't need over 250hp so should that matter? I'd probably like to just run Av Gas since it's really easy to get here and the price is usually tolerable.

2010 will be a new ball game but I'm looking getting a used already turboed sled, I think that's the only way I can afford one. So let's assume you were gonna by a used turboed 09 all stock. I think I already know the answer so lets throw in an aftermarket skid and see what kind of answers we get.

brent,
if you are going to get rid of your sled send me a PM. might be interested in it...or the motor

I feel that if your main priority is easy sidehilling, the Dragon is on top. My main reason for not going polaris is the decreased reliability motor wise compared to the cat (800 to 800)

My two choices for best reliability would be a D7 or an M8, both are great sleds.

I was reading a post somewhere else from Ken Climb and he claimed that the Polaris 800 turbos have no lag what so ever. If that is the case, and the cat does have lag, then as far as the best boondockin turbo goes, the polaris would get the nod. Throttle response is super important imo and the chassis are a wash imo. Therefore, the poo would be better for boondocking. But, I would say that the kitty would be more reliable, so if that figures into your equation heavily, then go cat.

All just my opinion, I dont own either sled so take it or leave it.

Did a '09 D8 with Aero66 setup. If you can cure the heat issues they may make a great boondocking sled, but if you ride like we do, I have yet to see a turbo setup that can dissipate enough charge tube heat to make more power than a stocker.....while in the deep in the trees at low speed. On a open hill or when temps are down it's another story. We had a good intake and ALOT of venting too. I would not do it again for the type of riding I like to do. JMO-

The more boost you run, the more "lag". Pump Gas anything's have no "lag".

haha, where'd ya get that idea

Anyway, Like he said I would have to agree, the D8's run strong on boost but they are also fairly prone to motor failures, even in stock trim. Heard of some issues with some cats too but it was all here say kinda thing. Either way it really comes down to setup and making sure you know what your doing when your tuning it. Take your time and learn it before you start pushing the sled hard and you'll be fine.

Other than that I'd say pick your poison between a Poo 7 or a Cat 8 based on what you like for feel of the chassis. You'll be able to make a little more top end on the Cat but due to the short charge tube ability on the poo, you can get a faster spool time with it thus making it better for the boondocking.

And Deffinately, since your fairly close in proximity to Bozeman, Get ahold of SnowJW here on the forum, he can give you a lot of help/insight on the BD kits if your looking in that direction and I think He's selling the OVS now too.

XC700116 · May 31, 2009

Oh and HP diff from the poo 7 to the poo 8 is a total of about 3/4 of a pound of boost. so don't let the 800 is gonna make a ton more power thing stear you away from the 700

The button not enough for you, hahaha.

Right now I'm just doin some lookin. If the stars align just right this summer I can upgrade but for now I thought it would just make for a good topic.
Don't mean to get anyones hopes up for selling or even buying.
Hayden WHEN I sell my sled you got first dibs....but I'll probably sell it out right FYI.

So I've heard a few times that the 700 Poo motor is better for boost then the 800.
Is it just because it's more reliable?
Is the 700 Poo more reliable then the M800 motor?

If you have no lag you have no turbo, there is no such thing as no lag especially on a 2-stroke turbo. If it is set up properly it can feel like the lag is not there but if you watch the boost gauge you will see the boost is not there when you crack it open off of idle.

I have built a few turbo systems on 4 strokes the can make boost with no load on the motor and at low rpm, you can not do this with a 2-smoker because you can not undersize the turbo on them

As buddy stated above the more boost you run the fatter your clutch weights have to be and the less low end responce you will end up with.

The trick is fuel managment, a good clutch setup and keeping it under 12 pounds of boost, the lag will still be there but it won't seem like it is, just don't say there is zero lag because it is not going to happen on a 2-smoker.

I'm not real sure on the M8 vs Poo 7 motor comparo, but from my experience the 700 poo has just been a near bullet proof motor. On a couple of occasions this season mine should have blown up but didn't.

Another freind of mine with an 800 had like 7 burn downs this season. same kit. I think that the biggest problem is that the 800 is already a struggling platform in comparison to the 700, then complicating it by throwing boost at it probably doesn't help. JMHO

The 700 responds real favorably to boost for whatever reason. My biggest reason for going to the 700 was the price factor and the fact that the 08 800's were already showing signs of issues.

I've also heard that the 600 CFI is a real buzz saw on boost too and I'm betting isn't too far from the 700 or 800 on the HP scale either.

Guess you should ride a Twisted Turbo pump gas M1000 then.

I must not get it. If a sled feels like it has no lag and has lag then my nytro feels like it has lag so there must not be any lag. I guess i've been looking at things backwards.

Yeah, that sounds about right...

Just for comparison sake, is lag a drag on the motor from spooling up or just simply the point in the motor where the turbo hasn't hit yet?

I don't think anyone expects to see 8 lbs of boost at 4500rpm, but there are some sleds that have so little lag that it's essentially imperceptible. Our M feels like a stock 8 for about 5-10 feet (from a stop) then you feel the boost, but it doesn't feel like the turbo is lagging on the motor like some of the earlier generation turbos I rode.

Changed my vote. Dave Halverson XP 800 turbo is going to be the best boondockin setup built!! Sick setup, beautiful quality, and a top notch guy behind it. Not to mention it will be on the best chassis in the biz. R&D Custom Turbo Works. And we will have go faster parts available to take your ride from wild to wicked!! A couple of these alterations should make it one bad setup in the trees. Stay tuned!!

The turbo XP looks good in the pics.
Does Dave have any footage of his turbo XP on the snow by chance????

SnowSnob · Jun 2, 2009

Two problems I see with a turbo xp, carbs and TRA.
If they can get the DPM to still work with a turbo then it shouldn't be AS finiky but I still think the EFI's would be more friendly.
I also thought that the TRA wasn't holding up to boost very well which is ONE of the reasons Doo isn't coming out with the xr1200.
Personally I miss the built proof P-85.

This is a Dave Bell turbo kit. Looks real good!
