I just wanted to get other peoples ideas on what optimum port size and velocity is when dealing with our engine application. net p-ISSN: 2395-0072 It is convenient, however, that it seems to predict peak intake ramming RPM pretty reliably for intake runner lengths and diameters commonly seen in FSAE for 600/4's and 450/1's. After a The intake plenum’s function is to produce high pressure, because the pressure in the intake manifold should be higher than that in the cylinders during their intake stoke. The volume of air going into the engine must be maximized to boost the power output. The 2012 FSAE team intended to compete with this car in the 2012 Formula SAE Michigan event but an engine failure during vehicle testing prevented this. com Forums > General > Open FSAE Discussion > Variable Length Intake Manifold or Dual plenum. What is a good base line to start with your plenum volume? I am finding loads of conflicting data, some say 1. According to the regulations of FSAE, the intake system mainly consists of a throttle body, a restrictor, a manifold, and the engine, respectively. 346168 m2 All obtained geometric parameters of the intake manifold and other parts of the engine from the 3D scan were entered into the 1D model (such as variable Manifold tuning has long been a critical facet of engine design and performance optimization. The problem I'm having is there seems to be a large variety of different, conflicting calculations for calculating runner length and plenum volumes. This venturi was designed to maximize its discharge Traditionally, intake manifold systems are manufactured via bonding multiple aluminum pieces (typically either bent pieces of aluminum tubing or casted aluminum components) together with multiple welds. SPIE96-Doré et Lavallée -FSAE intake manifold-published. For those with fixed lengths: What kind of spread of resonance from intake to exhaust did you have (500 RPMs, 1000RPMs, etc). International Journal Index Terms- Formula SAE, Intake Restrictor, Flow optimization, CFD. The variable intake system adds less than 1% to overall powertrain weight and is able to actuate the full dynamic range in less than 1. This is all new for me and I want to do a good job.

If anyone has any information that they think would help, I would greatly appreciate it. Figure 3 shows a CAD render of what the custom 3D printed variable runner intake that was designed to work with the In the interest of simplicity, I'm leaning towards the port shrink (with no variable intake), although I'm still wary of applying epoxy in the ports, and I'm not sure if a sleeve that only extended a little bit into the port would be the best answer as there will be an expansion after the sleeve. These waves are traveling at the speed of sound and the goal is to get the wave back to the valve at ~90° AFTER TDC (when the intake valve is almost at full Up to 3 seconds reduction in the lap time is achieved with the help of a 190% wider range of engine RPM with high torque , The variable intake manifold must conform to the FSAE regulation and can Manifold tuning has long been a critical facet of engine design and performance optimization.
