Seen a few of these here in Alaska riding ~1500' and they all over revved and were pinging constantly.
I'm not a turbo brain so correct me if my wrong, but my understanding of this system is it has an internal wastegate, and such has a hard time controlling boost creep vs an external WG. 2 of the guys I've seen said their boost gauge kept pushing 7-10lbs which, here that is almost impossible to clutch for. Especially if it isn't consistent(which in their case it was not).
On BD's website, the "not recommended" disclaimer goes away when you get the more expensive kit that has an external WG correct?
Silber definitely has a larger presence up here in AK than any other turbo manufacturer, largely due to runabililty at our low elevations.
I ran a silber on my ‘11 pro and through trying to get it dialed in I discovered riding placier one day that I unloaded at an air density of -800’. After I figured that out it all made sense. 2 kids now so stock-ish motors but I can say a few thing from personal experience of turbos at sea level
1) use good gas. Preferably race gas over av as there are different vapor pressures. Av is made for low rpm engines. Very stable and consistent but burns slower.
2) your pump gas kit will run, but your motor will see the stresses of a full race gas kit. The final compression that the cylinder sees of 6 psi at sea level will be approximately the same as running 11 psi at 10k’. You will need the octane/fueling requirements of a 11psi system not a 6 psi system.
3) as your motor is seeing race gas stress it needs race gas maintenance. Clutches need to be spot on, motor mounts will go faster ect.
4) Boondocker did I pretty good job on the sidekick. I’ve got a couple buddies running them in the soldotna area and they go good. Don’t make as much power, but they pull and go usually. Their clutching is crap for sea level though. Plan to have to change that.
