2012 BD turbo pro first ride report?? Issues?

[sledwolf]

Took my intercooled pro out today for a first ride and had a couple issues. First off im using the Bd recomended settings and 8psi boost with the EBC. The sled ran very lazy on the bottom end. It pulled fairly hard up high but not clean as i expected it should. I was very disapointed overall but im thinking its just a tunning problem.
What king of numbers are you guys running at 8,500' alt? On my way back the sled went into what i think was limp mode and would only pull 1/4 throttle. The engine lt was on and it had a DE7 code on the display.Turned the sled off and started it again and the rpoblem was gone until i rode another few hundred yards then did it again. When i got back home i found a loose plug on the PTO side. Im wondering if that could have caused the problem? I figure ill call the boys at BD on monday or tuesday and see what they can tell me.
The bottom end was terrible and didnt want to spool up very fast. Any insight from you BD guys out there would be great.
Thanks In advance.

The numbers mine came with weren't even close. My dealer set it up with his own numbers, ran great except for 2/3 @ 6700 rpm and full throttle 7000-8000. I leaned it out so hopefully that fixed it. I'd be happy to send you the numbers but I ride 3-6k. I hope you figure it out bud, the thing freaking rips!

Can you tell us what you were running for fuel?

The loose plug came out from Detonation. However if you never tighten them from factory they come loose very easy as the washer needs to seat, so any sign of det will cause them to back off.

What are your gauges EGT or wideband saying at different RPM's?

Have a Merry Christmas.

Sound's like that INKEDRIDER guy was on to something!

Havent put the gages on yet. Sound like i better. What do you recomend? I like the durrability of EGTs but i might opt for a wideband for tunning purposes. Im running 1/2 and 1/2 110 Sunoco and premium. I have the timing key installed and the 10% ethanol plug in. The funny thing is the sled didnt det the first 13 miles. It only did that on the way back in the last couple miles before i got back to the truck. Im running about 8.5 lbs boost maybe need to back it off a bit until i figure it out. The bottom end sucks for boondocking. If i cant do better than this im not going to be a happy camper.
I really apreciate the imput. Says allot about you Silber, thanks.

LOL. I had forgotten about that guy....Funny!

I agree!! Pretty cool of Silber to come on here and try and help out someone that bought a competing kit. It's one thing to offer outstanding customer service to your own customers but to someone else's??? No wonder he has the reputation he has and no wonder so many people love their Silber Turboes.
Hat's off to you man! I hope you sell a ton of kits. You deserve it! Merry Christmas.

What clutching is in it?

To much weight can make them lazy. Do the BD kits come with adjustable weights?

 

[dmkhnr]

The guys say that bd suggested fuel numbers are pretty close to spot on, and here they are.

There is also a supertuner adjustment to turn the aux injectors on that you might want to look into.

What clutch weights are you using, and what helix? If your too light/shallow it will overrev right out of the mid range and the det7 code will show up on your screen, shut it off and restart to reset.

Just to rule out the simple fact that your plugs might not have been tight from the get go would be my first trial.

I personally perfer a wideband, However alot of people tend to lean towards egts due to their longevity. However I have had great success with our widebands. I have yet to have a sensor fail. I have had them start misreading and clean them with a propane torch seems to bring them back to life. Both egt's and widebands can be misleading for tuning if your not familiar with them. Get use to what exhaust tone, while its rich or lean, that is your best tuning tool.

Det is very sensistive on these sleds. Make sure you have no metal contact with any of your exhaust parts or intercooler. If they have the ability to rub into the chassis while riding it may be setting your det of premature. Also after riding for awhile your setup is heak soaked, this is causing higher charge temps and making the DET more sensitive.

Make sure when changing elevations to either shut the sled off and restart it or let it idle for a few seconds so the sled can recalirate. The sled doesnt know until you do so. That why in the end of the day if you burn the trail back down without shutting the sled off it will come out of tune.

Make sure its not over revving, we have seen that the boost comes on so fast and strong that the sleds will overrev and the gauge cant catch it.

Im running BDs recomended clutching that came in the kit. Also thier #s in the box. I tried the high alt and the standard one that came in the box. It feels fat to me all the way around but without gauges im trying to be careful. It isnt over reving and the top end isnt to bad, the low and mid is just slow and lazy. It would make technical boondocking a bitch like it is. Ive got to figure it out. Silber offered some help im going to take him up on and also probably call BD on Tues. Its a bit frustrating but i think its all in the tunning. Wide open riders probably wouldnt have any complaints but in the tight stuff where you need quick spool and instant RPMs it wont do. I had a non intercooled kit in 2010 on the Dragon and it ran way better than this one does, should be the oposite.

you said you have the timing key installed, are you referring to an electronic timing key?

Yes. Thats it.

Turbo

Well first off the loose plug will cause det7. Second unless your trying to save money on race or av fuel then take the timing key off it does u no favors on bottom end.
The updated fuel numbers on their website for high altitude should get u very close. The clutch springs they recommend work. I would suggest using 10-72 Polaris weights at that elevation. The stock helix would probably work just fine but the turbo helix 42/48 is better.
If your using EBC smart then you will have a harder time tuning but will b happy when and if u get it dialed. You will also have to lean it out more then before with the four injectors but mainly because you have so much more ability to tune in every rpm in conjunction with boost. If you understand the boondocker box then you can tune your sled like no other company can.
Get yourself an A/F gauge! How can you own a turbo without a tool to tune.
An A/F for turbo application is the only way to go.
All that being said I have the new torque air box with cold air intake and new EBC smart and just got done riding at 8500ft and everyone that saw my sled or rode with me said it's far more responsive than stock(zero lag) with a lot more horsepower
Look over your installation to make sure everything is right and go with recommended fuel settings and clutching from boondocker, add 50Av/50premium turn boost to 10 plus and I'm sure you will get it figured out and have a great year!

DET will also cause a loose plug.............

 

[ghost rider]

Plug

DET will also cause a loose plug.............

So you know that his plug started the ride tight?
So your disputing that a loose plug which he stated wouldn't cause det7?

 

[Boston Racing]

So you think Polaris left it loose???

I think its more believable that his brand new sled didn't leave the factory with a loose plug. It is much more likely his poorly running turbo caused the plug to back out. Given the fact that the DET sensor tripped that is the conclusion I would draw. I guess I could be wrong

 

[Boston Racing]

I have dyno'd hundreds of 2 strokes on our in house Superflow and Dynojet Dyno's and can say that a loose plug is much more commonly a result of detonation, not a cause of it

 

[Boston Racing]

99% of the time a loose plug is telling you something. If you don't listen and assume that the plug was loose all along the next time there will be a dime size hole in your piston.

There is a slim chance they forgot to tighten it.

Sledwolf knows there is a problem bigger than a tech left the plug loose. We will help him get his BD kit running. Silber should get paid by BD for providing tech support after hours

Turbp

Did boondocker install his kit?
Do all the turbo kits silber sells get installed properly?
Do I care how many turbos you have dynoed?
I'm simply stating that first start with the obvious and work backwards. The first thing he noticed was loose spark plug(obviously it should b tight). Did I not state to go through kit thoroughly to make sure everything was installed properly?
He hasn't stated enough about clutching or fuel settings on here for anyone to draw a conclusion to problem?
It could b a stock Polaris issue?tps, etc.
How do most people who don't have an A/F or egts to gauge fuel diagnos if they are running lean or rich by pulling and looking at plugs? So could it b possible that one didn't get tightened? And don't tell me that without a tool to tune that he wouldn't or most wouldn't pull plugs to take a peak
