As for cams, who needs a more aggressive cam when the engine is boosted, there really is no need for all of that engineering. If you had a Normally aspirated engine then yeah go with the Shricks' grind and tune the ecu to the cam, should make another 30 hp on the NA motor.
Already spinning the SC faster.
In talking with the guys that have SLK32's & C32's the standard RENNtech & Kleeman cams report good results.
The stock exhaust is pretty efficient. There is very little to be gained HP/TQ wise in messing with it. Swapping in some high flowing cats will net you the biggest change.
The stock exhaust manifolds are a huge bottle neck. They are the biggest restriction in the flow path.
ECU is waiting on the cam & header decision.
Getting to 400 rwhp is not an easy task. 360-380 rwhp not a huge deal. Getting that extra jump is the problem. Not sure that it can really be done without spinning the SC near the limits of the electronic clutch and thermal efficiency's of the unit.
Of course in working to reach that level steps must be taken to address the cooling system in the car. This is my current project. I am working on a "stage 2" cooling upgrade for myself. My current plans build a foundation for a "stage 3" cooling system which would entail work on or replacement of the stock IC. I do mean the IC itself not the IC heat exchanger.
Need to also come up with a LSD solution. I am not thrilled with the 2 options on the market I am aware of. Time to start seeing how much work it would take to make a Quafie work in the car.
I could always take the "easy" route and hook up a 100 shot of Nitrous.
