Buick and Jeep V6

Detroit’s re-discovery of the V6 doesn’t surprise Offenhauser engineers at all. We’ve been making 360 Equa Flow manifolds for the V6 since its original introduction in the early sixties by Buick. Now also available is the Dual Port design which gives the V6 extra punch in low to mid RPM’s and better gas mileage without altering the emissions. Uses standard 4bbl carb from 400 CFM to 600 CFM depending on whether it’s for street or competition.

Dual Port Series

“The patented Dual Port is our STREET PERFORMANCE/ECONOMY DESIGN. in the Mini’s, the primary section boosts the fuel mixture to nearly the “speed of sound”, about 3 times faster than normal velocity. This positively gives each cylinder a full fuel charge every time to smooth out the power stroke. When engine or driver demand cuts in the secondaries, a cold (over 30° colder) and dense mixture is sent down the secondary runner to be rammed into the combustion chamber by the sonic flow to the primary runner. This adds up to 15-30% more horsepower, quicker throttle response, extended RPM range, better gas mileage, Quicker starting, reduction to exhaust emissions.
