Wow I decided this is my new favorite webpage you guys have the answers to everything. So I had just an intake and exhaust on my Del Sol and it obviousley made no real difference on the performance. I have an intake on the way because I love the sound and a header because my current one is cracked but I am sure that will not give me any noticable HP. My theory is that if I get an intake manifold to go with my intake it will make the short ram worth while and I might actually notice something? Does anyone have any suggestions as to what to get other than forced induction or higher compression pistons to make decent gains?
