Would there be any significant increase in power with a Holley Systemax II Intake over an Extrude Honed GT40 Intake? What are the ups and downs of this intake? Thanks.
I know you can't extrude hone the upper, I meant the lower, im sorry. My lower is ported by B&B and extrude honed.blue stanger said:You can't extrude hone the upper on a GT-40 intake. The runners are bent, thin tubes; unlike every other intake which is a solid casting.
