I know its directly related to what turbo youre running and how much boost is being put into the intake side, but please humor I certainly don't want more pressure in the exhaust than the inlet manifold, and am happy to sacrifice turbo response [via pipe size] for a clean cylinder blown down on overlap. Calculates tube diameter and length; Calculates tube length based on desired diameter; Works with header calculation 2 if desired; Enter your engine's displacement, number of cylinders, desired tuned This fan CFM calculator is typically used to calculate the cubic feet per minute of air exchange that may be desired in a building. 94 inches 2. Exhaust tubing size is listed as the O. Category Exhaust Diameter Range (in inches) Interpretation; Standard Exhaust: 1. When the exhaust from the engine flows over the turbine wheel, it spins, driving the compressor wheel, which draws in and compresses air into the Exhaust manifold design depends on vehicle application. To calculate proper header size, “engine rpm, camshaft choice, transmission type, and car weight can all play a factor,” Hill said. Go to small and you bottleneck the exhaust and loose power. Alternatively making a custom big turbo kit is always an option. First we need to Any time you can increase the size of the exhaust directly after the turbo, you will see a benefit - and the larger you make it, the better. To maintain velocity as the exhaust gas cools, it's actually a good idea to step down the size of the exhaust after the down pipe. 5 vs. 95 – $ 230. 98 inches 2. Choose the boost pressure you want to get at the three RPM points, in this example, 2000, 4000 and 6000rpm. 5 – 3. The table above is probably over-estimating pipe size, but you can see that a 400 hp vehicle with a dual exhaust system only needs 2 1/4 – 2 1/2 inch pipes. Divided turbo flange: The twin-scroll flange must be paired with a twin-scroll exhaust housing to maximize performance. 1. MK5 GTI Big Turbo – Short Version. You must also consider other components of your turbo system, such as exhaust Exhaust pipe diameter has a significant impact on engine characteristics.
