Best aftermarket headers for nissan titan full#
In a fixed cam setup, the space between the throttle body and the intake valve contains vacuum at zero throttle, less air at mid throttle, and sufficient air only at full throttle.īut with VVEL, the throttle bodies constantly remain wide open, allowing there to be plenty of air right outside the intake valve, ready to rush in. This allows your intake valves to open or close (valve lift) only as much as necessary, relative to your throttle input - something that wasn’t possible with a rotating lobe.VVEL involves a link-style rocker arm connected to a comma-shaped lobe that only rotates 90° back and forth. Traditional cams use egg-shaped lobes that rotate 360° to open and close the intake valve.But here, it is done by the intake camshaft. In a traditional setup, the amount of air going into your engine is controlled by the throttle body. It is the presence of this technology that makes aftermarket headers work so well with your 370z.
Your VQ37VHR engine utilizes something called a “ Variable Valve Event and Lift” system. VVEL + Good Scavenging + Valve Overlap = Mini Supercharger Effect They aren’t tuned for performance, are heavy yet are prone to cracking, and they don’t handle heat well. The OEM exhaust manifolds are clearly one of the parts Nissan needed to cut costs on. They’ve cut costs wherever possible so that more people could afford these cars. Nissan’s Z34 range is all about affordable performance. This said, your OEM manifolds aren’t perfect. So do your homework, and buy quality parts to avoid future trouble. If you don’t know what you’re doing, messing around with your exhaust system can create more problems than it solves. The engineering that goes into each factory manifold is mind-bending every pipe is precisely shaped and sized for a purpose.
