Stock compression and 10-12 PSI is just fine. I drove all over the damn desert and up and down the Rockies with 10 psi on crappier California oxygenated fuel and never once pinged or knocked, without an intercooler, and with ambient temps sometimes pushing 120 degrees. Also, that was at 10.5:1 compression. You don't need the aftercooler, or any intercooler. People blather on about safety and crap, but in reality, most of them are sold to people who think they look cool.Vortechs aftercooler takes up a bunch of space, makes the install an hour or so longer, nearly doubles the price of the kit, and doesn't do anything for a street guy. So if the benefits of a little peace of mind and a cool look out weigh the cons, then there you go.</blockquote>
