2009 M8 162” w/ Boondockers Pump Gas Turbo -> Review

2009 M8 162” w/ Boondockers Pump Gas Turbo -> Review

So I’ve held off on getting a turbo over the years because, for the most part, they have been known to be unreliable on a 2-stroke machine. So this past year I have been riding a 2008 XP 163”, a 2006 REV 151” and a 2004 REV 159” (the 2006 and 2004 are backup sleds which are a necessity given the fact that Ski-Doo’s rank a little low in the reliability department ). I ride every weekend from November – April and many days during the week. I mainly ride in Cooke City, MT and hit up several other locations around the Bozeman, MT area throughout the year. Both this year and last have been great riding years with unreal powder that really give a stock sled a workout. So what it came down to was simple, I was just fed up with riding in slow-motion on the deep days....I wanted something that would get you out of those situations where you had to poach over and over…I wanted something that would up the excitement factor and keep me a happy rider day after day…the answer was a turbo. I decided on a Boondockers Pump Gas (not that the others are bad in anyway – the Twisted Turbo seems like a winner!)

I contacted Justin at Code Red Performance in Belgrade, MT since I've heard through friends and fellow riders that he knows what he is doing when it comes to turbos. Justin had me up and going in less than 7 days with the turbo setup. I have to say Justin demonstrates exceptional customer service…hard to find that these days!! Given my experience with Code Red Performance they most likely will be doing a few more turbo installs for fellow riders this summer/fall.

On to the riding …

I’ve had the opportunity to put on about 450 miles with the M8 Boondockers Turbo setup. Just got back from about four days of riding Cooke in some of the best powder of the season! Joining the regular group of stock sled riders was McFlatty (Ryan Clancy) from New Prague, MN riding a Sled Head Racing REV triple.

The first day I started out on 91 octane with a pinch of octane booster to keep it safe. Ran low boost (6 lbs) and was very impressed with the power. For boondocking in tight areas the sled on 6 lbs of boost is perfect. No lag what-so-ever. I really couldn’t compare against the triple considering it was only pulling about 8300 Rs (should be pulling 9300 from what I am told) and bogging due to the exhaust getting suffocated by the deep snow, which =’s stuck after stuck! The only problem I had with the turbo was my own fault – I had the PSI fuel adjustments set too high so when I turned the sled off it was somehow flooding the engine and then was hard to start – I think. I adjusted the settings and it ran perfect the rest of the weekend.

The next day we went out I mixed in some additive to get around 100 octane. I turned up the boost so it was reading around 8.5-9 lbs. The triple REV was running at full RPMs and the snow was DEEP. The group headed back to some areas that are known to hold deep snow and put the sleds to the test. We cut through some steep side hills in thick timber and blew up deep creek bottoms and finally came to a rest after about 20 minutes of straight riding. I have to tell you, I’ve never had so much fun riding in my 9 years of sledding!! Later in the day the M8 turbo and REV triple did some pulls up some wide creek bottoms with about 2-3 feet of fresh which wasn’t sun exposed. Several times I gave the triple a head start and blew by it with ease…wasn’t even a competition.

If I had to do it again, I wouldn’t hesitate to spend my hard earned cash on a turbo setup for a 2-stroke EFI sled. Time will tell how many miles I get on it without issues. But in the end it all comes down to the “fun factor” - I was starting to get bored on the stocker and the turbo opened up a whole new world for me!!

Thanks for taking the time to read this lengthy post, hope I didn’t bore you too much!

Great to hear

Thats awesome to hear! I have a pump gas kit for my m8 on order from justin at Code Red and i cant wait to get it just waitin on money. Did you do the install? When you turned up the boost did you have to adjust the boondocker box?
 
Justin completed the install. I figured that was the easiest route to go considering he's about 10 miles from me.

I did not have to adjust the bb when turning the boost up. I have it dialed in pretty well as of now. Temps are good, plugs and pistons look good. The only thing I do not like about the setup is the harsh clutch engagement...but that comes with the package.
 
Id be careful of that octane booster stuff. Last I heard none of them do squat and there is no amount of additive that will make 93 = 100. You have to mix race gas. Just sayin...........

99% do nothing...a couple do well...(links take you to either reviews or data showing results)

Lucas Octane Booster is one that will get you to roughly mid 90's...

Torco Race Additive- will get you to 100 octane...but it is harder to mix in gas...it does not dissolve as well as the Lucas does...
 
Clutch engagement is about 4600.

I have used both the Klotz Octance Booster and the Torco Accelarator in place of race gas...looks like I will stick with the Torco.

I am curious on the race gas vs. additive argument...how many people use additive and what octane are you trying to achieve? Is it truly safe to use with a pump gas turbo setup running 8-10 psi? What do manufacturers of the pump gas turbos have to say about it? Has anyone used it for a season or two without issues and what kind of boost do you run?

Generally I just add the correct mixture to achieve about 94-95 octane to play it safe.
 
Why do you say your gonna stick with Torco?? Find out something about the Klotz?
I was told by a couple engine builders that if you only need mid to high 90's octane that the octane boosters are fine....anything higher and a person should really use race gas.

I've been having pretty good luck with Klotz so far but I also only need 93-94 octane. Next season on the NOS will be a different story though.

Those would be great if they work as stated. id love to see an independent test done on them. The others said there stuff worked too. A local refinery here has a knock engine and tested everything available a few years back... none did anything worth noting. sj
 
Thanks for the PGTM8 info. Was the triple Rev an 809, or maybe something bigger. How was your belt life/wear on the M8.
 
Torco Review

Here is a Torco review...http://volvospeed.com/Reviews/torco_accelerator.html

***The following comments reflect riding at around 6000' or higher***

So based on my research the end conclusion is that Torco, Klotz and some other octane booster products can get you to that 93-96 octane rating for lower boost applications. If you are running higher boost (8+ psi) on a PGT you will probably want to stick with a 50/50 mixture of race fuel/PG or run straight avgas (which appears to be another argument).

So what does Boondockers or other snowmobile turbo companies think of this?? I would very much value their honest opinion! So really a pump gas turbo is not a pump gas turbo at higher boost - well it might be but are you taking a big risk??

So if it is a TRUE PGT that means I can safely run 91 octane at 6000'+ with boost set at 8-10 psi in my 09 M8 all season long...or NOT?

I could be way out of line here - tell me if I am.

I've ran my PGTM8 at 7lbs on pump for 500 miles. I cranked it up to 8lbs last weekend with no issues. And I know a guy who runs 8-9lbs on pump with 1000 miles on his sled. How much boost you looking to run?

didja click on the links? the Lucas link is an independent test done by Volvo...

the other one is a reseller and the mix ratios etc. as well as a dyno on the product...loads of miles and reviews on the torco out there...

here is another article...http://www.europeancarweb.com/tech/0503ec_octane_boosters_tested/index.html
 
I'm sure some of you have seen this chart. Who thinks this is a bunch of cr@p or does this seem legit to you?

http://torcoracefuel.net/2-docs/accelerator-blend-chart.gif

Here is from teh same Volvo testing...(link is on first few words)

Torco advertises that it can raise 93 pump to 107 when used in the highest concentrations. Tested in the highest recommended mixture we saw an AKI of ~99 though a secondary testing method. 8 full points from 107 if you assume Torco was implying 107 AKI and not 107 RON. This would mean it was raising 97RON to 107 RON. If you standardize the results on AKI you will see that 107RON is actually fairly close to 99AKI. This is much better than you could hope for with the more common additives such as with xylene or Tulene

I am no expert, and I have no clue abotu this stuff other than research, adn those using it swear by it, but some level of concern about it mixing well with gas...so you have to empty bottle in prior to filling up to ensure mixing...

I posted this on a few other forums a month or so ago, and was surprised how many people use it with bigger boost...
 
DC read 88 that day and max boost was 9.3 running on pump gas with some octane booster. So not close to maxing out on the DC.
 
If you are going to use an additive look into Toluene.

Paint stores have it.
