This is my ridiculous cartoon car you all know and love                         The fun stuff: 19 feet long, 5120lbs 8 cylinders, each one with 944ccs of displacement for a 7.5 liter or 460 cubic inch engine. 220 furious horsepower. I've enjoyed this car for going on 5 years now, but the fuel economy suuuuuuuuucks, so i've decided to remedy that. Meet the two lumps, Larry and Barry.   Two ford duratec 30 3.0 engines. all aluminum, DOHC, 24 valve 60 degree V6s. famously used in minivans, Tauruses, the Mondeo 220ST, Noble M400(with turbos), and Every V12 Aston for the last 20 years(bolted together a lot better than i will be doing) It uses a remote water pump, with these 2 engines it's driven off the back of an exhaust cam, meaning not only do i not need a belt on the rear engine, but i can plumb the two cooling systems together and the only thing restricting how close they can get are the water inlets on the back of the front engine's heads. They're also under 20 inches and under 300lbs bare each which means they'll only be 6-10 inches longer than the 460 and i shouldn't have to cut anything. Combined they're also 3 inches narrower, 4 inches shorter, and over 100lbs lighter. I got a lot more bits than i expected. a lot of junkyards pretty much just give you the long block, but i got engine mounts, remote oil filters that i should be able to shim/clock to meet my needs, exhaust manifolds, and full uncut engine harnesses. Left to track down: -Lincoln LS 5R55S transmission -2 ECUs and someone who can code out Ford's passive anti-theft -2 Jaguar S-type 3.0 upper intake manifolds -2 dash harnesses from almost any vehicle -coupler to tie them together -tons of little fiddly bits LSes and Jags often show up in pick-n-pulls, so the plan going forward is to build this all up on the super cheap while doing a little bit of other work on the car, and continuing to enjoy it. The goal is to hit the road next spring with a straight piped ~450-500hp V12 powered landyacht. WITNESS ME, WINDBAGS

What really has me psyched is this. This is a DB9 manifold.  These are $80 headers for the 3.0  This is DB9 without the mufflers. https://www.youtube.com/watch?v=3L3Tu8SKQW0 I would expect the cam profile on the DB9 is different, although each of these engines makes 205hp and the early DB9s only made 450 with one set of accessories to drive, so they might not be that far off.

Shine on you crazy diamond. A bit of me is torn as I sort of want to keep that thing stock, but making a frankenmotor is just too awesome. A diesel swap in that thing must be too tame for you?

Real talk what kind of coupler setup are you thinking about?

You could use two megasquirts instead and use electronic throttle bodies with an electronic throttle pedal and add another sensor. I think that would simplify a lot of this mess.

Beach Bum posted:Real talk what kind of coupler setup are you thinking about? I was initially thinking flex disk, but i don't know if i'll have the space between the engines for it, so i think i'll be using a jaw coupler with one side keyed to the crank on the rear engine and drilled to bolt onto the crank of the front.  I'm looking for aftermarket harmonic balancers that i could get machined and pressed onto the rear engine side of the jaw coupler. A rigid coupler would be simpler, but i would worry about the engines transmitting vibration to eachother. Wrar posted:You could use two megasquirts instead and use electronic throttle bodies with an electronic throttle pedal and add another sensor. I think that would simplify a lot of this mess. I was looking at that, both engines have electronic throttle bodies and COP and I could theoretically run both engines off one if i can get them clocked together right but the tuning seems like it might be a nightmare especially with 1-2 degrees of give in a soft coupler. I'm looking at ~$150 in ECUs and harnesses, although tuning will then be more expensive unless i can get the entire harness, ignition cylinder, and key. That way i could also feel like a bad-rear end launching a missile, put the first key in and turn it, put the second key in and turn it, lift the safety flap and press the button. The factory ECU will also control the 5R55 slidebite posted:Shine on you crazy diamond. Everything diesel is crazy expensive and crazy heavy. I was thinking of sticking my 7.3 in there but that would involve both of my vehicles being out of commission for a period. and another 2-300lbs on the front end. I was also looking at electric stuff, but that's still a no go because of battery cost and temperature limits. Powershift fucked around with this message at 20:58 on Jul 4, 2019 |

I think they should be ok, typical applications in a driveshaft coupler would have them seeing higher torque due to the gearbox reduction, and they'll be ok for rotational speed as they'd have to be able to cope with whatever top speed would be in a high gear. Although you're not usually sitting at the max speed in top gear in a typical application. It'll be fine likely. If I'm understanding correctly and it's a guibo style coupling.

meatpimp posted:Would a BMW guibo work? If so, I'll contribute one to the effort. That balancer is off of a W124 driveshaft, and simplifies things a whole bunch, a new flex disk is only $35 shipped from rockauto so i'm probably gonna build the coupler out of W124 bits. Should be able to get a transmission output flange machined or sleeved to match the crank on the rear engine.  It's all designed for similar torque/speeds.

Speeds, yes, torque actually a lot more. Consider 250 lbft through a 4:1 first gear.

I'm absolutely not an engineer, but I think you'll want the engines solid-mounted to each other (but not the chassis, obvs) to avoid strain on whatever coupling you use.

Dagen H posted:I'm absolutely not an engineer, but I think you'll want the engines solid-mounted to each other (but not the chassis, obvs) to avoid strain on whatever coupling you use. Yeah, that's the plan, but there isn't a whole lot up top to tie the two together, which is one of the reasons i want a flex coupling. I don't want the stress of holding them straight to be put on the crankshafts. I'll have a little better idea of what i can do to secure them once i get them cleaned up a little and get rid of the poo poo i don't need. I might be able to put a heavy metal plate under the motor mounts against the block on the front engine and bolt them into where the A/C compressor would mount on the rear, then find somewhere up top to tie together to box it in.
