Silber settings let's see them

[XP2009]

Silber turbo kit.

I finally got out to Valemount to test my 2011 Pro with a 2012 Silber turbo. I was very impressed with this set up. My box never needed to be changed from Silbers settings, except me playing with Green trying to work out my high curse lean spot (with not much luck).

Elev ........... 2500 - 7200 feet
Fuel ........... 50/50 91/VP 111
Boost ......... 8 psi
Clutching..... 79 G


Box settings
4

4.5
2
4.5

Sled would over rev with any more boost. We only had 1.5 feet of fresh so I didn't change weight to add more boost as it wasn't needed. Over all I'm very happy with my kit.

I found if you find a stretch of trail that is slightly up hill and has a steady climb you can fine tune your low and mid cruise settings. It looks lean on the flats cause it goes lean when the motor stops pulling. So once your clutch shifts out at a certain speed the motor wont pull as much fuel because its not under a load. So keeping a good steady speed on a flat trail could be very bad. Your better off heavy on and off the throttle when on the trail. Your AFR will be all over the place but you will have plenty of fuel to be safe. Also I found the low 4k to 5k bog in the trees to get cleaned up a bit bye using lower octane fuel to keep the pipe hotter. I have been toying with opening up the spark gap to have a bit hotter spark and see if it heats up the pipe better, maybe an engine guru will speak up about the pipe temps and how they can effect a fat bottom.

Just an update had to throw a lot more weight into the clutch bad over rev! I'm now running 78 g @ 3 psi WOT RPM 8250 with 8 liters of VP 111 / tank @ 1900 ft
Green 4.5
Yellow 4.5
Red 4
G B. 4
Y B. 4.5
R B 4
AFR 13.4 on start up
Seems to be ok but need more snow this really sucks around here, have to do some more testing but off and on throttle seems good with no bog. WOT AFR is about 12- 13.
Does anyone have #'s for Valemount/Blue River running 91 or 4:1 91 vp or sunoco blend. Thanks in advance!

I may be running Val next week let you know, but I'll be running straight 100LL.

My Vale #'s are posted above. I thinking your clutch weight should be ok if you only want to run 25% VP111 (Mine was OK to 8 psi with 79G but I was being safe with 50/50) , change to your other waste gate spring, and lower your YB to say 2 up top and your good. Let us know how it ran !!

fuel pressure

Anybody know bow to adjust fuel pressure? Mine reads around 60 psi. The silber site says to be around 35 to 40. Could be why it idles funny

Justin said in a different thread that that was for the dragons and not to worry about it on the pro.

If the high fuel pressure were an issue then you would be running way fat (as in 50% more fuel) across the whole map, and if it even would idle it would be a VERY low idle.

What's ur A/F Gauge showing at idle?

 

[friscospices.com]

14.7 + OR - .2 consistant. Everyone needs to double check fuel lines and wires. Mine settled after 17 days of riding and rubbed a hole in the fuel lines both the pressure side and the return. Also had wires that had settled down and where getting close to rubbing. Just went over all of the extras on the kit to be sure. cleaned it up alot better now that I went through it again.

Mine varys from 18 to 11
Wot I've been seeing 9-11 today
Rpm dipped down to 8000 for some reason today
Been cranking the boost knob all day won't climb over 5psi

Had mine do that too, boost leak. I had to re-adjust the waste gate arm a little shorter and add another set of exhaust springs. Also check the bolts holding on the flange that the pipe mates to at the turbo. Mine loosened up over time.

arm

Had mine do that too, boost leak. I had to re-adjust the waste gate arm a little shorter and add another set of exhaust springs. Also check the bolts holding on the flange that the pipe mates to at the turbo. Mine loosened up over time.

So what am I looking for when adjusting the waste gate arm? The length of the linkage or is there some kind of other measurement? Should it feel loose with zero pressure? Or is it just an adjust and feel type of thing?

 

[m1kflyingtiger]

You adjust the linkage. There need to be enough pressure on the waste gate flap (little flat bar with a post attached to the turbo). When you take off the E clip and unhook the arm the arm shouldn't quite reach the post. You should have to pull it a little to get it to re connect. I think there's like 1/8"-1/4" that I have to pull on the arm to make it connect on mine. When you pull that arm it basically preloads the spring in the waste gate actuator. Without this tension The boost will spike on spool up, pop rack your waste gate open and bleed off boost.

ttt- anybody come up with any real good box number setup's looking at trying some different things this weekend to really get my sled dialed in even though the snow will not be ideal.

 

[m1kflyingtiger]

Glad this came up again. I'm getting a little rich on long pulls, and can't pull any more out of the red mode to lean it up. Right off the bat I see 12.5 AFR, but on a long pull it creeps down to 11.3 ish. Any ideas?

Just pull fuel out of the boost fuel #(blue/green). Pulling fuel out of this setting will make a much bigger impact that the red mode.Red mode is for fine adjustment.

 

[m1kflyingtiger]

Ill give her a try. If i increase the green will it ritchen up the boost fuel at all prior to going into red/blue mode?

are you talking green or blue/green?
regular green mode, you wont see too much of an affect.
blue/green- yes. blue/green is the amount of fuel per psi of boost that you are adding. So anytime it senses boost you will be adding X(blue/green) amount of fuel per pound of boost.

I don't know if that even answered your question, LOL.

Haha not really, but I re-read the directions and got my answer so no worries.

Best settings for a Silber???

Removed and in the trash

The worst experience I have had as a consumer

I had it sold, the customer had a question I told them to contact Silber and not only did he sell for less then I was asking (which was less then the snowcheck price) but he also delivered it for free.

Then I had his recommended installer do the first install $1000 later the sled runs like crap, vibrates itself into pieces. Drive out...Tow in

Then I ask said installer to fix, changed Dobek, checked his original work. Sled is returned without the oil return attached....Drive out.... Tow in

Finally connect oil return, fill with oil check installation. Ride out. Horrendous bog between 4800-6500 RPM's on the new Dobek, sled vibrates horrendously stalls intermittently. Drive out...Limp in

Three rides 40 miles...2 tow-ins

Thanks Silber and to the installer that no longer returns phone calls or stands behind his work, at a bare minimum please return the parts you took off the sled.

Congrads Silber on a fantastic pile of sh!t
