[LX5liter]

Hi Jeb,

I have the same amount of miles on my car and I installed a s/c last summer. 3-4 psi will not hurt anything as long as the engine is still in good shape. I started out with 4-5psi and was running 9psi for a while. I tore down the top end this winter for new heads though so I didn't get a lot of miles on it with the 9 psi. Even with the 3-4 psi you will notice a huge difference. If your suspension and tires are stock, first gear will be kinda useless.
