    4-barrel Opel intake manifold with pics

    I found this intake manifold after having misplaced it for many years.

    A little background first, it was custom made by Dave Cooley (used to work for C & R Small Cars) in 1984. The intent was to have them mass produced and sold in the US and European markets. So after some preliminary testing in the US, the intake and carburetor (I bought the 390 cfm Holley 4-bbl and the air filter) were shipped to Stefan Lukas at Parsget in Germany. He installed the setup onto an Opel GT, and proceeded to try to achieve TUV approval. Unfortunately, the intake/carb combination did not pass due to increased emissions levels over stock (Germany was really just then getting 'green' when it came to these issues). However the ironic thing it that nobody ever changed the jetting from stock! So it possibly would have passed with some fine tuning.

    Anyway, 9 months later the intake came back to the US, and it was then put on a shelf by Dave. My intent was to get a mass-produced intake for 'free' by supplying the carb and air filter (per a deal I struck with Smitty, one of C & R's owners). However without the European market to sell to, the intake was never mass produced, and I was essentially 'SOL'. Years later, after Dave had been out of Opels for some time, I contacted him looking for my Holley carb and air filter, and asked him if he wanted to sell the intake. We arrived at a number and struck a deal, and it was mine.

    Fast forward many years later, and I ended up putting the intake on my flow bench and finding some flow issues with it (mostly distribution). So I proceeded to correct these issues, and then again put it on a shelf. At which point I forgot which shelf exactly, and which box!

    So fortunately I recently 're-found' my intake, and took a few pics for posterity and historical reasons. So here it is:

    Hi Bob-

    If emissions were a consideration, can I assume the intake/390 combination was meant to work on engines near stock or slightly modified?
    If not, what sort of engine set up was it intended for?

    So, do you think this could ever be made to be practical for 1.9L or 2.0L engines?

    It was tested originally on a stock 1974 Opel wagon with a low compression hydraulic engine and an automatic tranny!

    In Germany it was run on a GT with a stock flat-top/solid lifter engine with a 4-speed tranny.

    The divider was added after initial testing showed the low compression engine bogged a lot under load. The divider eliminated the bog altogether.

    The intent was to fit ANY low port heads, any chassis (thus the low plenum height), and any engine displacement.

    Are you going to try and see if you can improve on the past and bolt it to a proper motor and tune it?

    I was in a salvage yard in the Oklahoma City area back around 1985 and ran across a 1975 FI manifold that someone had hacked the top off of and welded an aluminum 4-barrel adaptor plate onto it.... I just laughed.... For giggles, I asked how much and they answered with some outragus price, like $75. Again I just laughed.

    I like it Bob. Strange story because we all know that Holley's are jetted correctly from the factory.

    Gene, I'm toying with bolting it onto the 2.2 in my wagon. Depends how the 40 mm Mikunis run, and the fuel economy with each setup.

    I have the old 390 cfm carb but it's pretty haggard and needs to be overhauled. I also have a 450 cfm 4-bbl I originally got for my Bonneville project, and it's brand new in the box. The 2.2 *might* be able to handle that carb.

    I can see that you didn't stand a chance with the German TÜV in the 80's. That is definitely different nowadays, it should be doable now. Although, I'm sure that a Holley carb is high-priced in Germany, and not in everybodies budget (I'm making an assumption here).

    The intent was to offer just the intake alone, and to also offer the intake with the carb, air filter, gaskets, and throttle linkage as a package. A new Holley 390 is $360 from Summit Racing. Back 25 years ago I think I paid $240 for mine, which was about $60 more than a 32/36 DGEV cost back then (in the US). So not so expensive in the scheme of things, and with W.D. purchasing power I'm sure the cost would have dropped substantially.
