I'm wondering what if its worth the dollars changing from a cobra and 65mm throttle body to let's say a edelbrock rpm efi or typhoon and 70mm throttle body. My car has a d1b making about 12 lbs of boost on a 306 DSS twisted wedge , b4 afm cam and all the bolt ons. Just got a pms and shortly heading to the dyno. But before I head to dyno I might change the intake if it will make a great performance gain. If it doesn't pick up that much I'll save the money for other things. Just looking to learn from other peoples experiences with intake manifold combinations. Is the is the 65mm enuff? or do I need more?
Thanks everyone for helping on previous posts.
Paul.
