    Twin Engine V12 or 2x60°V6

    I'd agree, but one has to consider all the different aspects of engine balancing, from piston travel to crankshaft connection, ignition timing, fuel maps, angular moments and so on... but I think the part I'm interested in is "static" balance as well as rotational. Offset crank pins seems like a...

    Twin Engine V12 or 2x60°V6

    That is my primary or perhaps seconday issue with them [tongue]. Not a great pun given the 1.5. The other issue is the width in a narrow application such as mine. It's not a huge problem and even has its advantages, but the internal balance just makes the power and torque curves that I'm after...

    Twin Engine V12 or 2x60°V6

    Just to be fair, the 90° V6 from GM is still alive, barely, as the 4.3, though I believe it's branded as Ecotec now. Most of us are perhaps more accustomed to the old nomenclature, most recently Vortec, I believe. Only used in 1500 series trucks now, if I recall.

    Twin Engine V12 or 2x60°V6

    The Buick V6 was a great engine, but it's had its day. To me, any 90° V6 is just inherently messy from a balance standpoint. The 60° versions displace as much as 3.9 liters now from GM I believe, and make just as much power under boost with a lighter rotating assembly. Less torque, higher revs...

    Twin Engine V12 or 2x60°V6

    The V12 LS engine is part of my reasoning here, but I'd rather use the 60 degree engine and not cut right down the bore if I can help it. If I'm lucky with the coolant and oil galleys it may be feasible. GM was going to do this at one point but abandoned it, if I recall. The idea of using the...

    Twin Engine V12 or 2x60°V6

    I need to understand the architecture of this engine block better, but I'm starting to give in to the idea of cutting and welding two engines together, at least the blocks if not the heads, then line-bore and get everything squared back up. Actually cutting and welding this much material seems...

    Twin Engine V12 or 2x60°V6

    Now this is an interesting idea. How did all the ancillaries work, and more importantly, how did the drivetrain all come together in this case? A V-drive or some sort of splitter or transfer case could be useful here maybe. The ability to split the power for all wheel drive while keeping one...

    Twin Engine V12 or 2x60°V6

    [wink] I'd rather dig a start digging a foundry with a shovel than buy a V12. If it's that ill-advised maybe I should try to fuse two blocks together and make a crank. Seems like a breeze, no?

    Twin Engine V12 or 2x60°V6

    The engines would be rear to front. My understanding is tractor pullers and industrial hydraulic pumps may have couplers like what I'm after. Perhaps you could clutch the front engine and use the ignition system to bring it back in time. Unifying the exhaust and using that to each engine's...

    Twin Engine V12 or 2x60°V6

    I think a good question I should go ahead and ask to help with the balance thing is such: While a 90° V4 is inherently shaky I'm told, could it be on the nose of a V8 to only add power and balance to the two? Admittedly I don't know much about V4's aside from motorcycles and homemade projects...

    Twin Engine V12 or 2x60°V6

    I'm going to attempt to mate two modern FWD GM engines into a longitudinal V12. As the title states, they're 60° V6 engines that can be pretty easily setup for RWD applications. With FWD accessories, they should fit together tidily enough. My understanding is dragsters coupled engines like...
