| 1: | How much increase in power is there by installing an electric fan(s) in place of the stock motor driven fan? |
|
No hard numbers but the stock fan performs work by moving air so you can gain some horsepower (probably a small amount) by moving that work to an electric motor. One thing to be aware of: the stock fan pulls a lot of air. If your cooling system is marginal at idle or low speeds on a hot day, then stick with the stock fan until you fix your cooling system issues. |

| 2: | How much more horsepower can I get from a lightened flywheel? |
|
None. Chassis dynos can erroneously report reciprocating mass decreases as horsepower increases. A lightened flywheel does not increase the amount of fuel or air an engine uses so it can't possibly increase the horsepower of an engine at any specific rpm. What a lightened flywheel does is allow the engine to rev faster, which means you can get to the horserpower you have sooner and thus accelerate quicker. Remeber, acceleration is a factor of horsepower and weight. |
