900c! where is the sensor? thats pretty hot....
are those plugs any more prone to ignition break up high in the rpm band? got the part number off of them and where to order them?
what kind of timing advance you running at that kind of boost?.. cant be all that conservative with 900c temps...

900 c is just right, its on the inlet of the turbine, anything hotter than 1100 then I would be worried... Anything below 850 would tell me I am losing power from being to rich and alot of fuel is going through motor unburnt..
No, I run those plugs on the street, with premix, no break up anywhere.. They are NGK r6725115 plugs, I think they retail for about 30 bucks a pop on the internet, but there is cheaper sources than that..I get my Mother in Law to throw them in the mail from Japan, saves me a bit a cash there..Ignition is where its at, taking care to have the right heat range plug for what kind of boost you are running, and making sure there is no crossfire, or chance of it.Bizarre things start to happen to the spark once the charge gets denser than about 12 psi.. The spark tries to go any other place it can and just that can be a motor blower...
I dont inject added stuff , its just pump gas..The idea of injecting more stuff just complicates things I think.I keep my oil temps stable and as cool as I can, along with the coolant. Wandering temps also makes the ecu wander around on correction maps which is hard to tune for accuratley.
My next purchase is probably going to be an HKS knock monitor , I would like to push the turbo a little farther since 20 psi is really its minumum efficient boost pressure, its just gettting in the "zone" at 20 psi..
