[QUOTE="Torch10th, post: 11368642, member: 15703"] That's kind of the purpose of having the TiVCT. It allows the use of more aggressive camshafts while maintaining more manners at the same time. I think we're assuming here that these pieces are in fact so heavy as to induce noticeable power loss due to rotational inertia. Keeping in mind that rotational mass grows almost exponentially as you move the weight away from center, it doesn't make nearly enough sense to focus on the cam sprockets as it does to focus on the wheels/tires, clutch plate, flywheel etc. There' no shortage of documented 800+rwhp cars running around. Some with stock, or near stock engines. If you're building an all out drag strip brawler and every 10th counts, this is definitely an area that could be looked at. However most racing classes where you'd be in that situation may actually prohibit that type of modification. Especially if it's any type of stock class. it's a time/cost vs. benefit analysis. Spend time + money developing a lighter cam sprocket system that will be expensive and free up small amounts of power, or develop a lightweight flywheel that will be much cheaper and free up more power. I don't think you're wrong, but I don't think it would be time or money well spent. [/QUOTE]
