HM Turbo Days ---> Thumbs up!!

Now you are pushing boost numbers. Shane was running 7psi according to the video, not 6, and Matt was running 9psi not 10 psi. So there is a 2psi difference not 4 so at best 20hp.

And a few posts prior you told EZ that a 6psi vipec HM would absolutely smoke a 10psi Silber, but a 7psi hm vs a 9psi broken primary spring silber lost by 1-1.5 sled lengths, lets keep to the facts.

I have always said its a big advancement and have said in any thread you guys have posted I think it will be the future, but YOU have to acknowledge its not at that point yet or if it is it is simply not that much more impressive than other stuff out there for its hefty price tag. I totally understand that it is a very advanced system capable of doing almost anything you want to a sled, but just because you can change all parameters on a sled doesn't mean it will SMOKE anything else.

Does it idle great? Yes. Does it run great? Yes. Does it run 1.5x as good as just a silber turbo since that is how much the setup would add to a silber kit? I'm not so sure yet.

And to think it is not a product for me you are missing my point. ANY snowmobiler would love a standalone that you never have to touch, but so far you guys continue to tweak on the laptop between runs, or when adding or subtracting boost, etc. And no mountain rider will want to have to do that, drag racing is different because you have time to tune between runs. If it were truly a plug and play system that someone bought and never had to "fine" tune their sled with a laptop would be a lot more appealing.

To much misconception, the kit for next year was also there. If anyone knows Shane and I we are never done tuning. On turbo day I ran 6psi,7,9, and 10 psi and moved the fuel pressure all over because I was testing for the limits on the injectors for next year. I also had a 2012 with the kit that will be sold for next year and it works flawless. Guys Im sure will chime in about that kit also. Lets not get into a pissing match it was all in all a awesome weekend and we appreciate all the attendance. Hopefully next year will be another hoot!!:face-icon-small-win

i am not pushing numbers. read a bit below, jake 6 psi , turbomatt not sure but around 9 maybe more......but what the hell?? do we give a sh!t ??

fact is primary spring broken....not sure about that...but who gives a sh!t !!

lots of kit can be 4500$ with ECU in fact most of them.

that is when racing...he just add a tin y bit of timing to beat the guy by a sled!! beside racing no need for a laptop(on hm for now)

from cooke to my place and a month of riding after ....0 tuning done and needed.

HM Turbo Days

Shane's 162 3" track isn't made for the hard pack your running on. A shorter, stiffer lug track will always out shine a 3" on hard pack. Horsepower isn't the only variable in this situation.
 
I have attempted to remain positive, and not get into the whole Vipec shiz show that now is the norm on snowest. I was there, rode all the sleds, watched the race, and ate the barbeque.

It was a great event for many reasons. The hospitailiy, and willingness to share information and hand over the keys to big dollar sleds for anyone to try was priceless. Days like that are few and far between for a turbo head from Wisconsin. If it were up to me, I would do that every saturday. The knowledge at the bottom of that hill on Saturday is not something you come across every day. Spectacular to say the least.

This produc (ie Vipec)t is really intriguing. It clearly can be made to work. I love what the ultimate goal of the product is, but to claim that it is the perfect solution for two stroke turbos in general, at this point, is premature IMO. It could be in the future, and probably is (IMO), but its not there yet.

After ridin all of the Vipec turbos that were at Lolo Pass on saturday my opinions are as follows:

-Good low RPM response, and the sleds did not load up on down hills etc. I never once felt a low end stumble on any of Shane's personal sleds. I have read that the Vipec makes the sled rip on the low end like a stocker. You can pin them WFO from a dead stop, and they would not stumble which is impressive to me. But they still launch like a turbo sled, which will never be equal to NA sled IMO.
-I felt mid range stumbles on a few of the sleds when getting into and out of the throttle on climbs quickly and repeatedly. They were slight stubles and would pull through it very quickly, but they were there. I have faith Shain will dial this out over time, and my throttle habits can really test mid range fueling.
-Top end power was not what I envisioned after reading the many posts regarding huge track speeds and power at low boost (6-8 psi). The power was good for the boost levels, but was not the huge increase I had expected.

My opinion on turbo two stroke runability and power is based on these past experiences:

I ride a 2010 Boondocker M8 Turbo. 7-9 psi. It runs very clean in my opinion, but the ocassional stumble happens from time to time when I apply WFO from a dead stop. Other than the instant WFO from a stop, I do not have any hesitations, bogs etc. I run the same fuel numbers at 1000 feet that I do at 10000 ft. EGT's and A/F remain consistent, as does runability.

I have ridden TurboMatt's sled many times, and have been around it regularly since he bought it. His sled could be cleaned up a slightly in the low rpm range by pulling fuel but otherwise runs well and is very responsive.


Now its time for some Q & A

If I owned turbo sled that had the runability, response, power, and realiability of the two piggyback 800 turbo sleds I have experienced would I upgrade to a Vipec for next season:

Not a chance.

Would I buy a HM Kit with a Vipec if the money and situation allowed?

Heck Yes.

Why?

After meeting Shain (HM), and riding his sleds I have a lot of respect for what he does and how his sleds run. Hell, Vipec, Dobec, or Boost It and he will have it running very well as far as I can tell.

Nice rhyme to end it.. lol.

Keep up the good work turbo heads.

Hey guys,
Try and understand that Jake was riding his personal sled, he's an animal. He was just messing with his sled, Why, because he loves seeing what he can do and not do, trying every possible situation. He was non stop all day, letting people see the tune ability and how easy it is, putting it on 6 then 7 then 10 then 8, and saying here try this, letting everybody jump on his sled and try the feel of different boost levels. Thats not what someone will be doing normally, riding around with a lap top, thats just Jake doing what he does. There was a stock 800 turbo Vi-pec, Shane's 800 turbo Vi-pec, a stock 600 turbo no intercooler, and a 800 ported sled, all that were not touched all day. and all ran great. I can't talk all that tect crap but they are great running sleds, and super great guys, at Hm turbos, and Mild2wild. I will post some pics and vids, not for crap talking just for fun.
 
Hey guys,
now if someone can just tell me how to post my videos, there on my comp but tells me there is an upload error just on vodeo's.
 
It sure is nice to see this thread getting somewhat back on topic, which is:
HM Turbo Days ---> Thumbs up!!
HM Turbo Days was awsome!!! I wish I could go to a gathering every other weekend where a bunch of turbo sleds get together, you sit at the bottom of the hill watching them make pulls, you get to try everyones sleds out, drink a few beers, have some burgers, talk about turbos,etc,etc, etc. Unfortunately, where I live, that just doesn't happen.
I also got to attend the West Yellowstone sled Expo this year and man HM Turbo Days was like 10x better.

Keep up the great work HM.

That's all I have to say about that, unless Precision EFI is going to chime in and derail this thread once again, then I'm game.

The easiest way is to upload it to youtube.

Sorry didn't see the second page.
