I've heard about the meshing of gears, but i always wondered how they hooked up the trans. Excelent info.
Busted! Fuller just told me I dis-remembered my right from my left. As the picture shows, the left motor was the normal one that drove the rearend. Maybe I can get some points back with this pic of another clever and crafty two-motor car and its builder, Eddie Hill. Mike
That crossed my mind (at least I think it did . . .), but only as a faint ray of hope that my oldtimers wasn't flaring up today. Mike
Dont forget the Chet Herbert Bonneville streamliner with four 540 aluminum big block chevs. All wheel drive, sounds like a locomotive on steroids. It never did go as well as it looked or sounded, always in the mid three hundred range.
Looking at the Blower Drives, it seems these Two Engines both ran in the same direction. Do you know how they were hooked up?
Trying to trap me again, eh?! I don't have a clue, accurate or not, but I'll guess. If you're basing your ***umption on the belt tensioners I'd guess you're right. I'd think that Eddie (BSME?) was too clever not to have modified the tensioners so the pull was on the straight run of each belt. And what about the drive cases? Wouldn't one have to be reversed to turn the rotors in the opposite direction? Mike
There was a local guy, a retired Chrysler engineer, that took a nearly new Chrysler LHS back in the ninties and put another LHS engine in the rear. The car looked completely stock, but had two 230 H.P. V 6's, 460 total h.p. and all wheel drive. He told me about messing a Corvette at a stoplight till the "vette guy was doing hard tire burning holes shots to try and beat him. The vette still got smoked and the Chrysler didn't spin a wheel....I wish i coulda seen that, the "vette guy musta really had his pride hurt...by an old guy in a Chrysler
Mickey Thompsons Challenger cars or the Golden Rod: Freiberger has some of the best pics of the Goldenrod around...maybe he will post some.
No... just curious... Yeah, looking at the tensioners ( they are normally on the "Slack" side ), and the Blowers themselfs. The Blower on the Engine nearest to the Camera ( Left Engine in the Ch***is ) is driven on the outside Rotor. Which means it turns Clockwise ( looking at it from the front ), to be able to pump the Charge between it and the case, so that must be the same direction the Crank turns. If the other engine was reversed I would have expected the outside Rotor on that engine to be Driven. ( counter Clockwise ) This is cool... Could be a completely different way of linking the Engines.
So far as tractor pulling goes... most of the multiples use a gearbox by SCS, which can be set up with several inputs. Looking inside it, it's just a big steel box with meshing gears from left to right, more or less in a staggered row. The center gear is the output & goes out one side of the case; the other (alternating) gears are the inputs & go through the other side of the case. Like so: input, idler, input, idler, output, idler, input, idler, input, left to right. Not real complicated, just very, very, tough. Some of the tractors have right-angle boxes for engines four & five, which can be pulled out to change cl***es. SCS also makes smaller boxes to combine two engines into one output, which then runs to the BIG box. The big boxes run way over $5000. None of this is exactly low buck or applicable to us, but ya asked. The cleanest setup I've seen, auto-wise, was in the early '80s, combining twin 454s inline, with a cogged gear on the front flywheel chained with a four-row Morse chain to a similar cogged gear bolted to the rear engine's balancer. Similar to P&B's idea, I think. All polished & shiny. They timed the engines as a single V-16. I've got an old HR with close-ups of this somewhere. The owner's first name was Jay. The side-by-side doubles I've seen generally meshed flywheels & ran one engine in reverse rotation, & took power off one flywheel.
Here is a twin engined streamliner that ran a few years here on the salt here. Unfortunatley I never seemed to get a shot of it with the 2 engines in place. The first 2 images are of the car when it was under construction. This car was bult by a friend called Alan Murchison and Alan was over 60 years of age when he began building this car. It is all home built including the fibregl*** body. The only thinkg Alan didn't do was build the 2 mild 351 cleveland engines. Which are coupled together by a boat style dog clutch arragnement. He did this so that if he wanted to, he could disengage one engine and run with only one engine. The thing I love about this car is it is all home built and very old style, it says so much about Alan,who I consider to be a very good friend even though I rarely see him! Geoff aka whodaky
Why hasn't anybody posted pics of the Kenz streamliner? Well it's not that streamlined but ran a streamliner cl*** nontheless. I believe this car later got a streamlined body andr later on a third engine. But I guess that is out of the scope for this thread. Enjoy. //Magnus
I wish I had more pics....I only have this one.....from Billetproof a few years back I will see if I can talk Chris into letting me shoot some more photos of it.
Now that I think about it, didn't Monster Garage do up a twin engined puller? I think they just bolted the two mills together, nose to tail, with an adapter.
For whatever it is worth, albeit a bit off what you are looking for and one of the earliest attempts I would ***ume. This is Bowden's Mercedes at Daytona in January 1905 (I'm pretty sure of that date from memory). It was two 60hp Mercedes 4 cyl in line. Ran pretty strong and set some records. At the same time Willie K Vanderbilt had his 90 hp Mercedes on the beach. For those days that was some big horsepower.-Jim
I always liked the Hot Wheels Twin Mill(even teh real car is only a few years old). I've seen clips of it driving, I wonder if anyone's ever taken it out and really flogged it.
Looks like I made mistake... The "slingshot" type Alfa Romeo was the 160 Backseater ( 1954). It wasn't Twin Engined, It was 4WD. Never Raced, and they used a 159 Mule to test the Driving position...
The Invader runs a pair Chrysler 440's, 2 727 automatics, two driveshafts to two jag limited slip differentials with a short shaft connecting the inboard side of each diff. Shawn
Eddie Hill....his car had two third members in an axle he made, so each motor had its own clutch system...the motors were identical. Mutt
Two-Thing had motors connected at the flywheels, and the blower intake/exhaust reversed on the reversed motor. Mutt
Back somwhere around 1962 or so, a buddy if mine and I went partners and built a twin. A wierd one that we never actually finished, but got some pictures of it. It had a 324 CI Old's with 3 x 2's in the front and a 361 CI Edsel with 6 x 2's in the back. We also had a 283 CI Chevy with 2 x 4's that we considered sticking in front of the Olds for a trip, but never got around to it. It would have been something else had we ever finished it and took it the the drags.
Micky Thompson's Kilomonster had a motor driving each axle for four wheel drive, and he mated the motors by making special flywheels for the front of each engine to mate the starter rings of the opposite engine to make sure they were in sync. Mutt
