ok so after a good read around alot of people are favouring the performer X IM by edelbrock because they are good for around 6000 - 8000 rpm like most of our street cars are.

im just wondering if anyone has had any experiance with skunk2 pro and performer X intake manifolds and what would be best for an internal stock sirg b18c with i/h/e with plans on getting cams and a good tune next on the list.

alot of the people from the states are swearing by performer x over the skunk2 but im still yet to see a dyno sheet that proves they are acually better.

what are your experiances with different intake manifolds and what other ones have you tried like aebs, obx or blox?
