Ramchargers did try a collector header design a few times. Chrysler's experience in normally aspirated race engines showed significant gains in this area, and even more enhancements when properly matched with induction systems and valve timing. Shortly thereafter, engine technology, tires and clutch advancements negated any improvement that this heavier, less aero-efficient system could deliver.
Form follows function, or somethin' like that.
Other than they're stronger and vastly more expensive for today's TF cars, the basic zoomie header design has remained consistent. Copyright 1996-2001 by Bill Pratt. All rights reserved. No reproduction without express permission.
