Silber Turbo Question

[Iceman56]

Seriously do you guys realize how long 5 minutes is at WOT? Or even 2 minutes? this is a long friggen time to NOT be in and out of the throttle… I find it hard to believe there are many hills that you can hold a turbo pinned for 5 minutes straight..

You are correct, its a long time. We have a few climbs out, and you wish they were only 5 minutes.
These are long deep climbs. (early season)

Hey guys didnt realize what your riding areas are like. Maybe you dont need intercoolers.
Thought everyone was up against the same early season conditions.

I will say that there aren't any climbs around here that would be anywhere close to 5 minutes, but we did have one day a few years back where we had a 5' dump. All of us were pinned just trying to get up the road, but even this clip shows how long 3 minutes is with stock sled. A turbo would have kept going and exceeded 5 minutes, but I don't think it would be pinned the whole way. With super deep snow and the right conditions, it is not impossible.

Here's 3 minutes pinned on a stocker. Was an incredible day of stucks.

Thanks for the interest
My new sled has a complete new system with a water 2 air.
My last year sled with the big intake temps was a 2011 163 Pro.
With a 2012 Silber setup. I then did some upgrades,that got rid of the sewer pipe intake and replaced it with a silicone intake system that came up through the hood. CAI benefits are minimal compared to Silber pulling it from the OEM location
Replaced the stock Silber turbo with a KPA 2863 that I bought from Justin.
With the stock turbo and 5lbs intake temps were borderline
With the KPA and 8lbs is when the intake temps would get so high you couldnt touch the air box. Power would just go away. Never put a temp gauge on the intake,felt the fact the box was so hot I couldnt touch it, answered the question.
AFR was at 12.0 WOT
Altitude 3500 to 4000 feet at the beginning of the climb.
I looked at doing a W2A on my Silber system, can be done but very cramped with air intake running behind the engine.
Buy nice or Buy twice
I bought twice

What fuel controler are you running, some adjust for intake air temp some don't

Say that you don't have a cold air intake and your sucking all your air from inside the engine compartment. Only running 8psi and all riding is done in the trees, constantly in and out of the throttle. Always under 4 thousand ft. Would there be any benefit to running a nice wta setup?

With a water to air you boost gauge won't move as fast, you should hack in a cold air intake, it will help with tuning alot when snow is stuffing up your vents

Guys, after 10 seconds on a 100% load you are at max charge temperature on a turbo sled, so why are you talking about 2 or 3 or 5 minutes?? The fact is a water intercooler is a must on a mountain turbo 2 stroke sled...there shouldn't be any discussion over that, already been proven way before force induction showed up in the sledding industry.

That was great !!!!
Getting excited, couple more weeks.
And yes, this what we have early season.
89/90 season. Been at this a while.
Our so called mountain sleds of the day, couldnt make it up the forest road to the riding area. You could spend all day pinned and not get there.


And hey, most days I dont need all this power.
But when I do....
I want it to work without exception, all day


Thanks

I agree you do see some crazy intake temps when running no innercooler, that is what my reeds told me when the basicly got hot and ripped down the middle, you could clearly see they had a melted look to them, also you can tell in the deep pow, because you could just feel it, I now have a water to air innercooler for my 12 silber kit I will be trying out this year. I was running 10.5 lbs on 100ll at 10k plus feet.

Did you make your own air to water kit or source it from someone. Just curious of a rough cost. Thanks

There is a few ways to it. 1. Frozen boost on the internet sells prefabed intercoolers. 2 If you have a Silber 2012 kit you could get a core from a speciality intercooler core builder, and adapt it to your current air box.
Or 3 sell what you have and purchase a new kit that comes with the intercooler.
Cost, depending on what route you go. Roughly $1000.00

On the cheap its not to hard todo,

ebay water pump 50-100$
frozen boost w2a inter-cooler 200$
I would make my own heat exchanger out of copper. or scavenge tunnel coolers from another scrap sled or ebay.
50$ for misc fitting, wiring hoses.

Cant see it costing more than 500$ if you have mechanical skills.

 

[silberpro]

That would work

 

[adam8781]

Been drooling over the bully-dog kpa oiless setup.

Would w2a work with the way the kit comes? or would it need a different tune?
