I think your chasing something that is not wrong. I have a 2011 pro with BD turbo. I get this same problem. I have to let the sled idle a few seconds after running it. This only seems to happen once the sled is warm. But if I do not do this I have to hold it wide open to start it. Really sucks if your on it WFO and accidently hit the kill switch. Then its a bugger to start up... Anyways my sled has always done this, even with the new Long Rod motor and updated injectors, TPS set, new reeds ,etc etc etc. Just something ive learned to live with. It only seems to happen on the 2011s. Other then that the sled flat out rips
Silber Turbo not starting after running
- Thread starter Ckale
- Start date
He brought it by today and his power connector labels were worn and the oil pump was plugged into the ECM power plug and not the DC power. This can cause all kinds of weird issues. He is going take it for a rip soon and I'm sure will let us know what happened.

Yep! The worn labels had me thinking that there were two DC power plugs. Big thanks to Corey, awesome guy to work with and always very helpful.
Will report back soon
Did you get it fixed?

Changing the oil pump connection ended up not changing the behavior. Took it for a rip around the yard a few days ago and heard a rattling/jingling, ended up not going riding that day. Checked exhaust springs, chaincase, clutches...found the turbo has bit the bullet. (Luckily didn't run it long) Oil pump is working fine, so still not sure what caused the turbo to go. Maybe the previous owner of the kit wasn't honest on how many miles were on it. (since it is a 2012 kit it is not a kPa turbo) Anyways, now in the process of getting a new turbo. (probably will be a kPa) Maybe the turbo was causing some of these problems by spinning at idle, then hanging up, then spinning? The charge tube has always been dry (until now) while having this problem so it has not been caused by burning the turbo oil.
Again....will report back.
Again....will report back.
I had to exact same problem with mine, checked reeds they where good. WOT and it starts.

Got the new turbo installed today. Still trying to figure out why the old turbo went out though, would like to find some kind of reason to ensure that this new turbo will not have any problems.
Like stated before, the oil pump is working. I tested it again today before priming the system with the new turbo. When doing this I measured how much the pump is putting out over a period of time.
From what I collect, the Walbro fra-4 pump is supposed to put out 32gph (correct me if im wrong), so that would proportionally put the output at around 2 quarts/minute. After running mine for one minute it had pumped about 12 ounces of oil..close to half a quart. Would you say the pump is going bad? Or is this 32gph rating not accurate since it is pumping oil instead of gas/diesel. Maybe someone else has tested this. Just a precautionary thing to make sure this new turbo is getting adequate oil

The viscosity of the fluid will have a huge effect on overall pump flow especially considering the restriction in 1/8" fittings.
To confirm your suspicions, you could re-test the pump output using diesel fuel to see if you come closer to the pump specs. that are in print.
From my experience, these pumps produce very little flow when pumping any type of engine oil(0W-30, 5W-30, etc.).
Not the ideal pump for lubing a turbo by any means but I guess they are cost effective.........

I agree, I think a lower viscosity straight grade oil would work much better. It seems like the oil temp. never gets high enough to warrant the need for a multi-grade oil.
I use Mobil 1 0w30

I might switch to that and see if it pumps out any more. Do those numbers seem low to anyone or okay? From my experience it seems like a pump is either working or shot, usually not showing any signs in-between.
I have never seen one of those go bad. I also think the numbers are fine. The tank only holds a little less than a quart.
I thought the same thing as you with my BD turbo. Bought Bought a new pump same thing. Ended up putting a 12v battery in my sled and running my turbo crap off the battery. Oil pump pumps 2x the amount of oil now. Btw I use 0-30 Mobil 1 and it will pump a quart in no time.

Picked up some 0W30, and got the blow dryer out and let it sit on the oil tank to warm up the 5W30 before pumping it out. Amazing how much of a difference the temperature made, it came out at a much higher velocity than it did when testing it the other time cold. Filled it back up with 0W30. Pleanty of fresh snow today to break in the new kpa turbo, will report back later today

Well, sled ran great all day. Snow was awesome, no hiccups or problems, sled is finally running like it should. Sure is the funnest sled I've ever rode now, its amazing the things these sleds are capable of once boosted. Love it!
Would like to thank all of you for your input and help, it is much appreciated!
Special thanks to Boston Racing for meeting up with me and finding one of my problems, as well as putting a fresh flash on the Dobeck and getting the new turbo to my door in a very timely fashion. Always super helpful.
Thanks again and happy riding
