I'd love to see a digger with side by side 6's. Hmmm, do the HA/GR rules say anything about only having one engine?
I'll throw something else into the belt deal....it would be easy to vary the speeds of the engines in order to broaden the torque curve. In fact, you could use engines of completely different layout, and then under/overdrive them so they work off eachother. The possibilities are endless.
Yes, Thank you. Hard to keep up sometimes. But I don't believe that this thread is about building a HA/GR, is it?
I like the idea, but how manageable would two seperate drivetrains be? Even a little differance in throttle response, timing, shift points. If one motor lacked just a split second, would the power from the other motor take over the momentum and spin the car? Maybe I'm being too dramatic. Would it be like a car without a Posi, or a locker? (just one wheel working) Jeff
You could lock the two diff's together in the middle w a double splined shaft(that sounds gross....), I dunno. Spools, both diff's locked together? Maybe the torque converters would be able to allow the engines to turn at a little different speeds.....hmmmmmm.....maybe it's not figured out. Not yet!! hahahahahahahahaha! -John
No, it's about twin, side-by-side straight-sixes. At least that's the original post. Then the "well, why not just cut out the middleman and put a V12 in?" comments came along, and my reply was "because V12's aren't allowed in an HA/GR". I'm just restating it, not trying to start anything.
I've got 2 Chevy 250s waiting for this to be figured out so I can put them in something. You go guys!!!
This man's on the right track.....go find yourself a Allison aircraft engine, V-12, run daul turbos on these....all the speed equipment still exists for these......remember they were used in WWII fighters.... then in boat racers, and some cars.......
I'm not gonna say anynames but a long time ago....this motorcycle racer wanted 2 engines on his bike. After building a completely new frame.......and we hooked the monster all up......broke about 3 HyVol chains.......made an adjustable engine sprocket so we could time both the engines so they were hitting at the same time perfectly on the engine power stroke and it lived.....it also sat some incredable 1/4 mile times..................
go find yourself a Allison aircraft engine, ....all the speed equipment still exists for these...... Yeah, I see 10 or 15 of them at the swap meets and yard sales every week and the speed equipment is so plentiful that you can't even give it away. I took a bunch of it to the s****yard along with a pallet of NOS Ardun heads and the guy only gave me 10 bucks. Barely enough for a sixer, a little gas and some Cheetos
An offset axle from a 4WD truck would work to get the pumpkin on the correct side along with the trans. Just solid mount the steering knuckles. Or do this:
If you can narrow a rear axle, you can build one with 2 pumpkins on it. And since one of them needs to be locked, the easyest way would be to use a 31 or 35 spline spool on one side and a 28 spline diff on the other. That way, the long axle can go all the way through the spool and into one side of the diff to mesh the two together.
might have the same amount of cubes, but just imagine how many people will stop by with confused looks on their faces. that's what draws me towards this. i've been thinkin a lil about it. how many people will stop and check out a v12, not as many as 2 inlines under the hood!!! CREATIVITY!!! good thing i have enough room under the hood of my truck for it!!
Have you done this? I don't know diddly about 4x's, but I've considered this and maybe comments could be added to this thread: http://www.jalopyjournal.com/forum/showthread.php?p=3672365 First, would the front end as a rear end turn the right direction? Second, how would one solid mount the steering knuckles? Third, what about brakes? I've thought about using an offset front end, taking the steering components off, and adding backing plates for drum brakes. That brings up: Fourth, will that mean I need to either leave the width the same (most seem wide, but maybe I would need to find a narrower front end to start with) or shorten the axle(s)? Thanks, Kurt
I haven't done this myself, but I worked with 4x4 Jeep parts for a couple years. Front axle choice will depend on the axle design. Same way the rock crawler guys run rear steering, it's usually just a flipped over/around front axle. A Dana 60 will work nicely and handle tons of power. As for locking in the steering it's just a matter of bolting the tie rod to a rigid point on the axle. I've seen Jeep guys build an offroad trailer using a spare front axle, and locking the steering in place by bolting the tie rods in place to a bracket on the pumpkin. GM used the Citation front end in the Fiero and all they did was lock in the tie rods to the frame. Brake will depend on what the axle has on it. Gonna have to do some fab work to make it work, but you can always just swap left to right. A Dana 60 is pretty wide cause they were found under big trucks. If you found a Toyota front axle it would be narrower.
Ha, thats funny right there. When I started working on mine, I actually wrote Mr Ivo a letter and sennt it to him. No responce. Since then I have learned alot, that was three years ago.
First, would the front end as a rear end turn the right direction? reverse cut gears Second, how would one solid mount the steering knuckles? pull the knuckle ends off the axle, mount solid ends Third, what about brakes? anything you want I've thought about using an offset front end, taking the steering components off, and adding backing plates for drum brakes. That brings up: Fourth, will that mean I need to either leave the width the same (most seem wide, but maybe I would need to find a narrower front end to start with) or shorten the axle(s)? depends on the axle you use. With something like a Dana 44 you can find a bunch of different lengths, depending on spline count, then trim your housing to fit
If u can think it, it probably has already been done. Back when the rod mags were little there was a 51 chevy featured with side by side v-8's with separate ******'s and pumkins'. The motors were canted away from each other. Maybe some other ole' timers on here saw it too.
O - M - G !!!! Is that the nicest engine you could ever install in a traditional rod? I never knew that anyone had ever made an inline 12. Damn, that l - o - n - g cylinder head looks great!
How about a pair of BMW V-12s, canted away from each other, with zoomie headers (yeah, 12 pipes going vertical between the engines) and a transmission out of a tractor puller with one drive shaft/one pumpkin. You know, like the Hot Wheels Twin Mill. OK, Inline sixes would work too, but man, seeing 24 zoomies with 12 going vertical between the engines...wild
If these engines were ever put in boats they are some reverse cams out there.The old way in twin engine boats was to run one engine reverse rotation.Now all engines turn same way and the reverse rotation is done with the gear behind engine.My 2 cents
