Turbo or SLP kit

[MTN Powderhound]

Was wondering what some opinions are on either, putting on the SLP stage 3 kit or turbo on pump gas. Buddy put an SLP kit on and is running 55 mph track speed. One of the videos I watched said that they were running 60 mph track speed. Is it worth spending extra 2000$ on turbo kit for 5mph?

Matters if you want to spend $2k for performance that is a tiny bit better than stock, or $4k on performance that will make a stocker look like a 440.

If I get a turbo I would only run it on pump gas. What are the stock Pros running for track speed on average?

 

[dmkhnr]

Trackspeed isn't a fixed number. My slp piped/ported M8 usually ran low 40mph trackspeed in 2' of powder at 9k elev, where my turbo sled runs 55-60 mph track speed in the same snow.
I ran up a hill on the M8 in 6" of powder and it hit 44mph, slowly climbing to 48 mph by the top. My turbo hit 90mph track speed instantly and held it all the way over.

I'm sure the slp kit serves its purpose, just like my slp M8 sled did. 85% of the time, I could go anywhere a turbo goes, but on the 24"+ fresh powder days the modded sled is just climbing a few ft higher than the stockers (if not dead even), whereas the turbo sleds are going over the top.

If slp says 55mph trackspeed, you got to ask what elevation, what type of snow, and what mph was the stocker running?

Obviously I need to do more research. What boost can you run on pump gas? Any Idea on horse power with pump gas? Thanxs

What elevation?

slp kit will make your sled a little more fun and your wallet pretty light. turbo will make your sled wild, and the wallet a bit lighter. on pump gas, not sure on a power #, but on the hill, it will smoke the N/A mods by a long shot. the higher you go the more the turbo is gonna show its potential. same with deep snow, the deeper it is the more they start to pull away from NA stuff.

as far as track speed, unless your on the same hill, side bye side... its not worth much.

I ride 7-10k elev and woudnt think twice about running straight 91 oct non ethonal at 6#. Id say this is 160-170 hp at elev. Call Shane at hm. He's got the best setup for the pro.

I was having the same debate.. And I said 15 horse for 2g or 20-80 horse for 4g.. I figured jus go turbo , do it right the first time, and not want more later.. Nice thing about turbo is if you want more hp jus turn up the boost/ make sure fuel is appropriate.
Cuz we always know we want more..

So I'm as close as ever to pulling the trigger on a turbo, but are there any drawbacks? I like the sound of the Silber "100% bolt-on" since I can't fab the pipe and whatever else it used to require myself. Are there other options for true bolt-on turbos out there??

DO IT!

There are a couple others out there that are bolt on as well i believe.
Nice thing with the bolt on is if your motor blows up you can jus take a bolt on kit off. (and it was never even on )
But from my research no ones price is as good as silbers, also guys have been saying his kits running awesome this year.

I don't think at that elevation you would be happy w/ a pump gas setup. The 860's both Polaris and Skidoo that I've been around walk all over turbos "actually" running pump gas, mix a little race and run the boost where it justifies the cost of the setup, and things change. I realize that you weren't asking about 860 sleds, but I believe the slp stage 3 is in the same ball park cost wise, at least w/ the Skidoo. Not sure what a 860 Polaris costs, but the ones I've been around are much more impressive than the pump gas turbo Polaris sleds I've been around.

Agreed... Most PG turbos run in the 6PSI range.. They are not even close to a good running Big bore.. Once the Pro hits 8PSI then they run about even with the Ski Doo 860(At least one kit makers).. at 10PSI (far from pump gas on a long pull) the turbo will walk the big bore .

As for stage III kits.. they are not in the same performance realm as the big bores...

The Pro PG kits run well and are a blast to drive but the idea that they are killing good running N/A sleds is simply false... Despite what you may read or hear..

I would say, if you have the $$$$ go for the 10PSI boost level a(50/50 mix) and then you will have some good power .. at PG boost levels.. power is good but the extra $$$ you spent to get the turbo will not be that impressive once you run into a GOOD running N/A sled..at least not for the extra $2500 spent.. BUT..still much better than stock...

Then there is that new Polaris BB kit coming next year . Another option...

If you're the only one of your friends running a turbo and you like hill climbing agaist your friends you'll be dissapointed.

In my opinion it's alot more fun to be comparable to your friends so there is still a challenge in beating them. The turbo (I'm talking race gas cause that's what I have) takes that away in a hurry.

If it's running good. And even then I'm just waiting for it to hiccup or go down. Ask yourself is a turbo right for your riding style? My riding style has two throttle positions. One when the sleds turned off and the other is to the bar. That doesn't fit the turbo near as well as a modded/big bore.

I have honestly had a lot more fun, especially trouble free fun on a modded sled. It's usually a big bore pulling my turbo out.

Just something else to consider before you drop the cash.

We do not quote track speed because there are to many variables to take into consideration.

I have personally owned both the turbo, stage III and IV as well as tested and owned several big bores. Each kit has it's place and customer. I don't think you can say one is better than the other. A more accurate conclusion would be Kit A may be better than the Kit B for customer X but not for customer Y.

X2, All depends on what riding you do the most of? 80% trees big bore, so on and on.

860 form Carl's is about the same as a BD turbo, Priced them both a couple yrs ago for may 09, I went with the 860 and it is a blast. And with any luck jack will have the 900 out for the pro this next season, cross your fingures. Then there will be no question about it big bore.

If you do most of your riding where the hills and chutes allow you to hold it wide open in the one minute and longer range, then I would say boost it.

This is just my justifacation of my own to why I went with the big bore over the turbo.

I've posted this link before. It shows that a N/A engine with a 70 degree air intake temp takes in the same pounds of air that a turbo sled at 6 pounds boost without an intercooler, or one that doesn't work correctly(250 degree air).

In this case the big bore should win by having a bigger displacement.

LMAO at 860s keeping up with pump gas boosted sleds.
