Thommi,
as you know Sudam will be run on 16% nitro and as i understand the engine comes shimmed for 25 to 30% nitro. Have you tested on 16% and if so, what is the ideal head clearance for it.
Have you been in Bs. As in the past? what would be your suggestions.
Who are the Brazilian drivers who will race with Werks engines??

I have tried the engine with 16% and it works fine, and for a start, I would actually stick to the original deck height with a RP7 plug. As the B.A. track seems to have a very long straight, this might give you an advantage there. If you need more torque, reduce by 0,05mm and/or try the RP6 plug.
Yes, the engine comes shimmed for 25% and it works fine out of the box. For original deck height, I recommmend using the RP8.
Increasing deck height gives you a bit a wider tuning window, and this might be helpful, and it's less stressful as well on the plugs.
Look out for Felipe Chaud, who is on the official WERKS Brazil Racing Team. I am not sure if Rafael Alves will be there too, he is a very experienced engine guy and can help you with whatever you need. Besides them, there will be Hernan Uner and Nando Lima (who might use the WERKS engines, not sure yet, as he has multiple engines to choose from).
I have never been racing on the B.A. track myself, but heard it's quite big and with a pretty long straight. This should actually favor our engine. I have tried short manifolds to simulate such track conditions, and if you have some short manifold around, put it into your baggage. The ultra short manifolds are in my opinion too short, especially running lower nitro content.
Hope that helps!
