Browsing an old book theres a picture of an old Okrasa ad which shows dual port heads with a very funky looking single carb manifold
When did they sell those? Did they offer single and dual carb kits at the same time or was it a very early thing? |

i think the single carb was generally for aircraft applications. |

From what I've heard, but can't confirm is that Speedwell is working on these manifolds...
Would be great if true |

Any proof that this manifold was ever sold to the public?
I have seen this brochure and a review in AM&S, but have never seen a survivong manifold, or a picture of a complete engine installed in a car.
(Okrasa also had larger Nicasil cylinders in their brochures that I strongly suspect were only "paper ware") _________________ __________________________________________ |

I remember seeing an EMPI Sportster many years ago with a 40hp Okrasa breathing through a single carb. _________________ EMPI Power Rules! |

Paragraph above the power graph generally reads "special manifold combining greater elasticity with more power, when keeping the normal carburetor with different jetting".
Could be compared to the 1600 single-port engine rated at 57hp to the 1600 dual-port in '71 (though with a larger carb) rated at 60hp. So with the OKRASA, instead of the stock 36hp, maybe 38-39hp? Whoopee. Remember that the graph shows the Euro hp rating; a stock 36hp US SAE rating was 30hp DIN. |
