Actually it always was about restriction. If it wasn’t there wouldn’t be a need for headers . The data has been out there since the fifties. If the pipes are too big for the volume of air flow the scavenge effect is lost hence the use of collectors. Don’t mislead the audience into believing...
From that article:
“The interesting thing about this test was the fact that the shorty headers produced only slightly less peak power and torque numbers than the long tubes, but the torque gains down low were substantial.”
Where that comes from and has been tested and discussed on Engine Builders, the tv show is the over sizing exhaust pipes. The functionality of X and H pipes is directly effected by the volume and pressure flowing through the pipes. Without enough volume and pressure the advantage is diminished...
Believe it or not long tube headers can cost you power when you’re under 400hp. You need some back pressure. Back in the day everyone ran long tube headers and what they found out is better performance was obtained with shorty headers on lower hp motors. If your running power adders (blower...
2005 & 2017 PW’s with 35 Mickey Thompson BAJA MTZ.
3/4” clearance getting in the parking lot at work. Love to go higher.
Write ups in the past said to not lifting the PW because of all the issues.
My *$$! Start adding and go higher. If it tips over then it’s probably no longer your...
