MG MGA - velocity stacks

Is there anything to be gained by fitting velocity stacks inside the air cleaners of a std. road going A ? A couple of suppliers have nice shiney ones listed, are they just nice shiney ones ? All the old motor cycles I've owned always had a curved bell mouth fitted. Sean

Go to eclectic motors web page.

Carl has done some dyno runs testing the velocity stacks. The result seemed to be that only some very specific designs gave 1 or 2 hp.

BTW they won't fit inside a standard air cleaner. you'd have to get some socks or make a filter box.

I do run one on my supercharged B and when dyno tuning tried it with and without.Could not read any improvement.
I left it on as it became part of my cool air intake.

Most people seem to believe that velocity stacks are of no benefit, or a benefit of around the 2 BHP figure.
However the factory engineers thought that they were worth putting on the mga twin cam engine and introduced them as a standard fitting during the production run. See image.

The flat, horizontal plate is to keep the sides of the filter element apart, to stop the element collapsing with any suction.
