Any one out there thought about or better yet tried , or even better done this? I thought it would be cool to run 2 straight 6`s side by side,I figured you would need to flip one of the heads around and possibly link the 2 intakes togrther ? how would you tie the mills into 1 ****** ? any ideas ??
I liked the thought of it, then i realized that the sum ***** would weight a ton. Steering would be rough. Since were just daydreaming here hows about making them rear mounted engines?
I've thought about doing a U12 engine, not seriously, but it's crossed my mind. I don't think you could flip a head as the pushrods will be on the wrong side. Put one engine in the ch***is backwards to get the intake and exhaust on the correct arrangement. There was a recent thread about side by side twin V8's with pictures of trans attachments. Miller did a U16 in the 30's. Two straight 8's side by side to meet the new cubic inch rules.
side by side may be a ***** to do but somewhere somebody on the HAMB could do it , im sure a couple of inline inlines has been done as its been done with drag cars for years!!..
I wouldn't be too hasty to determine someone else's idea as stupid. Being a straight six fan, I would like to see that idea come to life. I Imagine there was atleast one old hot rodder back in the 40's that thought pulling the fenders off of a duece coupe, and maybe chopping the top or channeling it down on the frame was stupid. maybe you might even be doing dome things that others may think are stupid. Hell, I drive a lowered 59 ford wagon with a small as hell 223 six popper in it. is that stupid too? maybe you think it is. Oh well. but then again, I guess everyone is en***led to their opinion. but I would think that putting 2 straight sixes next to eachother wouldn't be too different than what they use to couple the engines together on a tractor pulling tractor. It would be really sweet in something wide like an old cabover.
I'm not aware of any engines that you can flip a head backward. I'd luv to see one. lots of twin engine cars built. Since no one grinds reverse cams you could try to machine a gear drive that runs the cam backward, then you have ports that dont work well at all, and they'd better not wiggle or the "connected" intake would break. There are no "stupid" questions, only stupid people, but this project would be stupid to attempt if the builder wasn't exceptionally skilled fabricator/machinist/rodder.
Tommy Ivo's method for the side-by-side 'twin mill' Buick was to mesh the flywheels and reverse the firing order on the second engine to run backwards. The second engine was a helper, and the output went to a single trans. I suppose you could do that with two side-by-side sixes, but it would take a ton of machine work.
Im a six fanatic. Im building a killer 300 right now. But trying to engineer two of them side by side is wacko. Its called a V-12, thats how ya do it. Yall type fast, I see Miller beat me to it.
Gary Wales, a noted Rolls guy and Kent Fuller were working on one about 10-15 years ago. Don't know if it ever was finished or what. He did build this, Maybe not HAMB friendly in some peoples opinions, but absolutely *****en as far as I'm concerned http://www.conceptcarz.com/vehicle/z15255/Van-Blerck-17-Liter.aspx
Agreed... Twin I-6's would be heavy as hell, and you would only end up with about the same cubes as a big block V8. V12's are readily available, and speed parts are out there. The Jag 12 is one option and has a good following. The BMW 12 is an even better option. McLaren used a production Beemer 12 block as the foundation in their F1 supercar. It's all aluminum, tough as nails, and looks very cool... Not very traditional tho.
That's a pretty astute response right there. I think it would be workable, lots of messin' around to get it right. Of course, if both cranks are going CW and you drive a common gear with them, the output would be CCW. Makes me wonder what kind of readily available transfer case might be adapted to work, maybe one of those big***ed ones out of an old M35.
This was done on a dragster in New Zealand. I believe it was from the 1970s. He had them facing opposite directions, looking like a flat-12 configuration. I've got an article around here somewhere. If you want, I can try to dig it up.
I have actually been working on this very thing for the past 3 years. why people say its stupid is one of the reasons I keep working at it. Dad alway's told me as an aerospace engineer, "for every person out there that say's it can't be done, there are 10 more people out there standing in line to prove them wrong" I have the logistics worked out, now I need money.
I hate getting in on the hair-pulling but I hate it when people say stuff like "thats stupid". Oh well though, people are en***led to their opinion..... it's something you have to live with, especially on an internet forum. I love others opinions myself, more than once I've aborted a plan 'cause someone brought me to my senses... I can't see what would not be cool about it, if I was going to try it I'd make it count....use two 300 Ford sixes, hard to poke fun at 600 cubic inches in ANY configureation! Maybe not the best for all ****-u-ations but at least it would be cool. And for christ sake can we quit saying "stupid" this & "stupid" that? It's so.....so.....STUPID!!! -John
Alfa Romeo did a rather nice version in 1931. see this link for more info: http://www.ultimatecarpage.com/car/3192/Alfa-Romeo-Tipo-A-Monoposto.html
Maybe the Australian or NZ HAMBers can tell us more about this, but there was a 4WD twin straight6 dragracer. I've seen a pic of it on the HAMB, long time ago. One engine powered the front axle the other the rear axle. It had handeling problems, but I thought it looked pretty cool...
Turning one head around is stupid. Do you think there may be some diffaculty with pushrods? Come on people.
Do it, post pictures, laugh in the face of adversity. I say go for it. Engine bay width is gonna be a booger though.
If you started with a Jag twin cam six you would only need to retime the cams to make the intake and exhaust ports reverse. Don't know how well the now exhaust ports would hold up with that much heat they wern't designed for. If you started with a Hourning or Wayne head GMC you could maybe get a billit cam ground to reverse the ports. Same heat issue as well as spark plug location would be poor at best. Without a cross flow head manifolds will be tight. Why not just get a V12? If you tried to turn around a Pontiac OHC 6 head your combustion chamber would move off center of the bore quite a bit. Whats the point. It's dumb.
why put any other motor in anything than a 350 chevy? it's so much easier, why would anyone actually want to do anything different? the machine is calling, it wants your originality back. come on people, just because something may be difficult to do or not have a relative purpose doesn't mean it shouldn't be done. if that was the case we'd be having discussions around the camp fires in front of our teepees trying to figure out how to modify our horses!
This is Kay Sissel's car, I saw it run at Sears Point a few years ago. It ran pretty well on the first p***, then later in the day it kicked a whole lotta expensive stuff out of the left side of one of the motors. Beautiful car, no matter where you look.
The best thing about the HAMB is that there are folks out there that will think outside of the box...The idea you have is not going to be getting you more power or look really neat but it is an idea and if you can accomplish it all power to you. Who knows it may lead to further development like 2 Buick straight 8's together. I think side by side is the hard way to do it, in line would be tons easier. Putting it it a COE would be a gas, in the bed of course..
