Air box mod save $$$

[Greg_imp]

For those considering modifying their air intake:

I did dynometer runs comparing various intake and exhaust configurations.
1) Stock everything
2) Unrestricted exhaust (Yoshimura full) with TSR air intake
3) Unrestricted exhaust with stock air intake (stock air filter)

While the air-fuel ratios changed, the HP curves for each of these configurations was exactly the same.

I am unwilling to compromise intake air filtration, but before you conclude that the stock air filter is holding the performance back, another member ran butt dynos comparing unrestricted air intake (no snorkel or air filter) to stock and could not detect a difference.
