Hey, first I have to say that I am a novice when it comes to mods, I've only started getting into them a few months ago when I bought my GP and ran across the GP Store. My GP is a GTX and I'm just wondering about having a cold air intake with the Ram Air... first if it's possible, second if it's worth the $ to combine the two? Also an unrelated question, anyone know the approximate formula to figure out for example, if you add 30 HP at the crank what that translates to at the wheel? Thanks in advance!
