Anybody familiar with H.u.G. manifolds out of Germany? These ones fit 40DCOEs to a 1.9L head. I couldn't find any info on the company (possibly they were bought out by dBilas?).

The manifolds are longer than the Irmscher shorties (left), but they still fit (barely) in a GT engine bay without cutting up the heater box.

So the choice will be longer intakes and virtually nonexistent air horns, or the opposite... short runners and ~1.5" trumpets. I realize that differences in each manifold design come into play... but in general, if the airflow "run" length remains unchanged between both options, how would the overall performance characteristics differ?

Sorry, no. Afraid it's a bit of a "one off"! Almost everything you see here is hand fabricated. Took most of 3 months to build and tune. Using Bosch rotor "rev limiter" to curb "loud pedal" happy footedness . . . a MUST!

Actually, that's the accelerator cable . . .

BUT he asked about the cable ACROSS the valve cover and that's the accelerator cable. I routed the cable for the choke behind the head, not across the valve cover. I fabricated this setup for my '72 GT in the photo.

BTW, DellOrto tuning was done with parts from your neck of the woods, Eurocarb LTD in Tilehurst, Reading. Only place with DellOrto parts I could find at the time, nothing in the States.

thats the other end of country to me
i was lucky that i have a place 5 miles away that got me jets when i had the lotus engine in as that was dells as well
re jeted and rolling road setup for what was $45 but that was in 1985
they loved me when i went back 3 years ago with a 3.4 jag in the gt with 3 48 webers on the side (much rubbing of heads and scraching of manly bits to sort that as all carbs were jetted diff:D )still they did enjoy the test drive on o country road afterwards:p
BTW happy birthday for the other week

Re: Alternate single sidedraft . . .

Kinda defeats the main purpose of the SD carb . . . most direct shot at the intake ports save dual SDs. Between the two shown, the parallel one is the better "airflow" choice because it adds one 90° bend whereas the second one shown adds a 90° bend AND a twist. Not real great when you're directing "wet" flow. Downdraft, synchonous carb is the best "flow" option with our standard manifolds, I'm afraid.

I'd be curious to see what a single 40, 42, or 45mm sidedaft on the top adapter really flows like on an Opel. That much bigger of a carb, with both the adapter and the manifold ported nicely, and the straight shot of cold air into the carb might more than make up for the added turns.
