Silber turbo questions

[rboyd]

Hey guys just wondering if anyone could answer a few questions about silbers turbos.....

1) I do most of my riding around 2500 feet and wondering if you would need to run race fuel or av gas at my elevation ?

2) my buds and I make 4 or 5 trips a year out west around 8000 to 10000 feet, is there much to changing setups from 2500 feet to mountain elevation ?

3) I'm no mechanic so Im concerned about the reliability of a turbod 2 stroke. Would I be melting down motors every year with this setup? A few of the guys on here already talked me out of nitrous. I just want lots more realiable hp ! Please help


4)and finally if I decide to go nuts and buy a silber turbo what are the wait times to receive the setup ? I've read that lots of you spoke for them months ago and still haven't received them.

1. It will depend on how much boost you want to run. At 2500 feet I think anything over 7-8 psi would need a mix of premium and race or av gas.

2. It's easy. There is an altitude adjustment setting on the fuel controller that will lean or richen the entire map and keep the other setting on line with eachother. So when you go to 8000 you just lean it out like 1 light.

3. Turbos are very reliable if you keep your af in check. Some choose to replace pistons and reeds each season but I know people with 2500 miles and haven't touched them, so is sort of preference. But i like silbers kit because he injects the additional fuel over the reeds helps keep them cool so you won't break petals.

4. The reason no one has received is they spring or summer checked them. Silber redesigned his setup and is beginning to ship. I ordered mine a month ago and will receive it around thanksgiving. I wouldn't wait long though he told me he planned to do 200 kits for the season and has sold 150. So not a lot remaining if you want one this year. I would call and talk to him and he will give you good insight to these questions also.

If you really have questions I'd just call Silber. He has been extremely helpful, has always answered the phone when I have called or called back within a half hour when I've left messages. Heck there's even been times when I don't leave a message and he still calls be back because he sees the missed call. For as much as he has on his plate his communication is actually very good, and its nice still being able to talk to the man himself versus some other companies having to talk to guys who have no clue what is up.

1) depending on your boost level, will determine the amount of race fuel or av gas you will need to run. The pro rmk Det light is so sensitive its impossible to get any sort of boost at lower elevation without lowering the compression and retarding timing.

2) When changing major elevation, you will more than likely want to readjust the adjustable clutch weight to pull the correct RPM, for the elevation and boost level your choose to run. As for the control box it will follow for elevation changes and should stay in tune.

3) Any turbo setup will be reliable if you run enough octane for the boost you are running. We also havent had any reed failures on the PRO, on any test sleds or customers that we know of.

4) Kits have been shipping, and we are doing our best to get them out the door in a timely fashion. The sooner you order the sooner you will recieve a kit. Again we are building 200 kits and over 150 spoken for, we cant produce them all over night. Thanks for your understanding and patience.

If you have any futher questions or concerns feel free to call me anytime night or day, I will gladly help you out.

Thanks

So if a guy is running say 10lbs of boost at 6-8k ft on AV, and his programmer is set for 10lbs. And he unloads his sled at 2000ft then rides the trail all the way till 6kft, as long as he is taking it easy no more than 3/4 throttle on the trail, hes good to go? as the controller will adjust for the altitude.

Thanks!

the knock sensor is realy accurate and can detect knock very early, if you have control over it(setting) and control timing,making your injectors spray or adjust every 100 rpm true the complete rpm range and have engine protection features such as timing retatd ,fuel cutoff ect., you can easily boost 7 psi at SEA LEVELon premium, stock head with 0 detonation.

2) When changing major elevation, you will more than likely want to readjust the adjustable clutch weight to pull the correct RPM, for the elevation and boost level your choose to run.

should.............

3) Any turbo setup will be reliable if you run enough octane for the boost
that is common sens!!having control over timing realy help too.
We also havent had any reed failures on the PRO, on any test sleds or customers that we know of.
turbo sizing is realy important(justin knows), if running no water or air intercooler, charge temperature will go high(depending on turbo size) and will delaminate the reeds and break them.....that is the most common problem with 2 stroke non intercooled setup.

4) Kits have been shipping, and we are doing our best to get them out the door in a timely fashion. The sooner you order the sooner you will recieve a kit. Again we are building 200 kits and over 150 spoken for, we cant produce them all over night. Thanks for your understanding and patience.
keep up the good work.

I see no reason this kit would not run at lower elevation with stock head and timing.If the fueling is correct and proper octane is being used You should still be able to run lower elevations, just not the same boost levels you would run at higher elevations. So If you run 10psi say at 5000 feet why could you not turn the boost down and run say 5 psi at see level using the same octane?
