Anyone made any gains by extrude honing the intake on the HP500 efi manifold? BOB

Anyone tried this? BOB

Bob the gain is in the shape cross section and length of the piece not the way it's finished extrude hone works if the key factors are in place but make sure the shape is done before the piece is honed so as to get the biggest gain out of it . If you're looking for power out of an intake I personally think you should call Wilson Manifolds no one can make an intake work as well as him look at all the nextel teams using him he does all my road race intakes and my 320 ci Chevys make 715 hp at 8250 rpm.Good luck Laz Mesa

Thanks,Laz. BOB
