Really liking these brackets, well done!
I hope it all works out for you, and the factory comes to the party.
I have also heard that on really high horsepower motors, you can get cambelt stretch(from the head lifting?)
This really is the best solution for rock solid timing.
Its not an RB26, but ive been running this kind of setup for a while now(RB30)
And apart from some early setup problems(mostly the 2.0mm clearance issues)
Its works a treat with a Motec m48, as we all know how crap the standard dizzy is(the gear gets backlash)
I saw evidence of timing wander on the dyno, the tuner thought it was quite comical +/-6deg
Im just running a steel bolt in one of the adj camwheel holes.
Motec 6 point trigger disk which is mounted on a machined hub and bolts through the balancer.
Both GT101's are mounted on 6mm alloy bar brackets.
300+rwkw and gets flogged regularly(RPM limit@7000)
Once again, best of luck.
