Jan 03, 2012 · looking at the 2 intake ports in head and i'm looking at 2 bbl intake runners. i would say if i blew foam into runner and took it out the cross section would be smaller than pair of ports at the cylinder head. questions: does this speed up the air? if i keep the runner 'full size' up to... Our Harley's M8 ported heads, getting ready for our propritary valve Job. These things will flow 360-375 CFM without increasing the cross sectional area of the port. That means high velocity (High cylinder fill) which equals TQ. We get 40-50 more CFM from the intake port over stock. (Flat TQ across the entire RPM range with the right cam and pipe).
But, by leaving a step between the intake and the cylinder head, the high-flow area of the cylinder head port encompasses a larger portion of the intake manifold port, and the quality of the flow into the head is improved. So, I'd advise NOT to port match your heads to your intake manifold, but rather, leave 1mm or so of a step between them so the larger cylinder head port can suck more effectively on the smaller intake manifold port. port in the cylinder head fuel manifold. Current secondary filters are disposable, spin-on filter cartridges, which entrap particles down to 1 micron in size and may plug on water.

- Bianchi catalogueAug 22, 2015 · The hemi heads and high compression will only work with the high intake velocity of his small ports. High compression by itself, in a slower-burning stock engine, would cause knock and runaway overheating. In a low-intake-velocity engine, squishless hemi chambers would encourage detonation because such engines lack any other source of intake turbulence. The porting wouldn’t work as well without the hemi head to diffuse its flow.
May 12, 2008 · Cylinder Head Porting and Polishing Myths It is popularly held that enlarging the ports to the maximum possible size and applying a mirror finish is what porting is. However that is not so. The intake port cross-sectional area of a racing cylinder head with the dual purpose high performance street motor aspirations of the 351C 4V had to walk a fine line; (1) the gas velocity needed to be high enough to keep the fuel in suspension at engine speeds which are lower than the engine speeds encountered by a racing motor, (2) the gas ... All cylinder heads sold individually. We developed two rectangular ports: a high velocity 308cc intake runner that produces incredible torque and a 345cc version that's perfect for big inch, high rpm Rat motors. The Iron Eagle's raised exhaust port outperforms its cast iron competition but still fits most standard headers. Edelbrock Big Victor High Velocity Intake Manifold - Chevy Big Block, Satin Image may be a representation of product. While we try to get as close as possible to the exact part, it is not always possible. In some high-speed diesel engines, turbulence is created by an auxiliary chamber referred to as an ENERGY (AIR) CELL. Energy cells differ in design and location. In most engines, the cells are located in the cylinder heads. One type of energy cell that is located in the cylinder head is a divided chamber and turbulence chamber.
An easy way to gain 20-40 horsepower on any 1955 and newer Small-Block Chevrolet V-8 (except later-style LT1/LT4 engines with reverse-flow cooling) is by installing a set of Vortec cylinder heads.

It takes a careful balance of flow, airspeed, port cross-section, and choosing the right components to get the most out of any cylinder head. Dart 370cc oval port Aluminum cylinder heads have high velocity 370cc intake runners that produce incredible midrange torque and throttle response. Oval port heads really “wake up” a big block in marine applications, or in a heavy car with an automatic transmission. They also work great in a light car with a tight torque converter.

Yep, the main advantage of high-velocity porting is it's believed to squeeze more charge in, faster. A side effect of this is becuase the charge is entering the cylinder faster, when the valve closes the charge will be piling up behind it like a traffic jam because of the momentum of it all.
Mar 29, 2008 · High-velocity airflow makes all the world of difference when it comes to throttle response and low to mid-range torque, and that makes the car fast on the street and fun to drive. For that purpose and your compression ratio, I would opt for the 180 heads and a smaller cam, like the XE 262.

The whole high velocity port theory is proven to work. The physics are solid and the major manufacturers are beginning to catch on. Huge ports may make big numbers on a flow bunch but they don't make power because they destroy velocity. I know for sure my CRF"290" makes more power for bottom to top with the smaller port 08 head. SOHC heads really open up nicely on the exhaust side. You can go further than they did on my heads, but my car is NA with a hopped up street cam and we didn't want to kill the port velocity and low end. My redline is only 6400 rpm. For different applications like a high revving race motor or FI you could port them more.

The Aussiespeed brand of street and racing products & speed equipment was started in Adelaide South Australia in the year 2000. From 1 product the Aussiespeed range has grown to over 500 products. If have the high velocity model, it should already be shooting around 380-390 FPS with 0.20g BBs out of the box, so if it's far lower you could consider checking for any deficiencies in air seal or compression quality. The stock motor is supposed to handle M120, although it's still a mediocre motor. Cylinder Head Porting and Polishing This port and polish process to the cylinder heads and intake ensures that the flow mixture enters the cylinder head chamber with the maximum amount of velocity. The same goes for the gentle reshaping of the exhaust to ensure a match with the header opening to prevent turbulence in the exhaust chamber. Proper porting keeps the port as small as possible while still providing the needed flow for the application. There are ways to trick the flow into thinking the port is straighter, bigger, smaller, etc. It's a balance. Anyone that says high velocity porting is the only way to go is an idiot.
