DUAL CARBURETOR INTAKE MANIFOLD DYNO TESTS
This series of dyno tests were run within a three hour window using one of our super
touring engines.
All test runs were conducted with the same engine & dual Stromberg 81 series carburetors,
with the only change being the intake manifold itself.
The three intake manifolds were the Burns, The Equalizer from Charlie Yapp and the
Tattersfield.
All three intake manifolds performed well.
The best overall for an engine used for touring, 1300 to 2400 RPM was the Equalizer.
The best for high performance such as hill climbs with higher RPM usage was the Burns.
The Tattersfield made the most horsepower in the 1300 RPM range  & was close throughout
the rest of the test.
