    Mercedes V8 Inlet Manifolds

    Funny that an analysis of the ports puts the 6.9 at an advantage for several reasons. When I eventually get to modifying my 6.9 it’ll get some serious porting…

    Mercedes V8 Inlet Manifolds

    Well some things happen all at once & looks like I’m sending the ‘template car’ to the new fabricator 16th Sept. Intake & exhaust will be done at the same time. I’ve resigned myself to the fact the current guy has put it all on the back burner indefinitely. I needed more of a go getter with a...

    B+B CW311

    Here’s a few more still frames from the video plus a contemporary article sadly incomplete atm. I’ll try to get the whole article to post soon. Note the car must’ve been so loud the engineers had to wear earmuffs!

    Carobu Engineering - 560 Dyno Testing

    And this is the radical Ford Indy engine from 1964. Obviously intake & exhaust have been reversed. So what is the answer to all this development when applied to our engines?? Straighten out the bends of course! I may have a partial solution….

    Carobu Engineering - 560 Dyno Testing

    Now compare the Ford Coyote V8 which is actually VERY similar to the M119 in many ways….

    Carobu Engineering - 560 Dyno Testing

    Well I’m hearing all sorts of things ATM. Firstly that the pic of the AMG M117 isn’t the original but sort of a mockup. Key indicators are the fuel rails not bolted down & a dizzy which wasn’t fitted to the original pinstripe race cars. I was assured the hp figures are correct since they...

    Mercedes V8 Inlet Manifolds

    Here’s a few other M100 variations. Another view of the Rote Sau with cross ram & twin throttles The CW311 & the Espace were later variations (and designed as street cars) which featured a single throttle.

    On hp figures the AMG 500SEC (5L) made 454hp so the 560 should make quite a bit more…

    Carobu Engineering - 560 Dyno Testing

    Seems like they got overwhelmed with work or they’re having management issues. No updates on FB since 2022 & their website hasn’t been updated either. 🥴😌😕

    W126 Exhaust Performance Upgrades

    You get what you pay for & this guy does amazing work. Don’t forget prices for everything have gone up since COVID. In saying that my quote was sight unseen & I suspect the final cost will be lower since it’s a pretty simple design compared to most other v8 systems. It’s a shame he’s not closer...

    W126 HPF1 suspension repair

    Great work!!! Basically NEVER throw out a strut since they can be rebuilt or worst case used for parts. Those that are selling them are trying to make huge profits in a limited market. Makes it rather unfair for someone trying to get their car driving again.

    Mercedes V8 Inlet Manifolds

    This custom manifold is rather high & I wonder if it fits under a std hood. The Sauber M117 from the C8 still retains a distributor despite the other significant modifications!

    W126 Exhaust Performance Upgrades

    The Sauber M117 TT plumbing is no fun & I can see why few early Benzes are modified to include turbos.

    Mercedes V8 Inlet Manifolds

    The trouble with multi plenums & throttles is that you can potentially halve the volume & velocity of air through each & it makes any pressure variations more significant. I looked at the 450SLC & initially thought it’s just a std 6.3 manifold with a slightly different shape, but I then realized...

    Mercedes V8 Inlet Manifolds

    Here’s a seriously modded M120, but the manifolds are only marginally better than the std ones. The last group of pix give you an idea how tight things are in the centre and the fuel rail just makes it worse!

    W126 Exhaust Performance Upgrades

    Oh I should probably add these here. Not how I’ve designed mine, however this workmanship is superb.

    Yep that was my first version too. I’m now looking at something far more advanced
