New 2022 episode! The Stroker big block Chevrolet is already a solid, reliable, and powerful engine favored by gearheads everywhere. But what happens if you take two identical big block Chevrolet engines and link them together on the dyno?
We do something that has never been done before: build two identical 496 Big Block Chevy engines to run on the dyno...at the SAME TIME!! It’s do or die as we hook up both 496 Big Block Chevy engines to find out exactly how much power two of the same engine will make running in tandem!

This is awesome! Now of course we wanna see phasing tests, but I wanna see the engines phased so each bank fires evenly, into one 8-1 header on each bank! The sound would be INSANE! So that would be 360 crank degrees out, 180 cam degrees out. They'll fire into an 8-1 like a inline 8 would. That would be ideal exhaust header scavenging.

@jckf 2 жыл бұрын

I want to see numbers for equal phasing vs. "in-between" phasing where one engine has a power stroke in-between the other's, so it would fire 1 1 8 8 4 4 3 3 6 6 5 5 7 7 2 2 with equal distance between each event. Maybe even combine that with a 360 degree offset to make 1 6 8 5 4 7 3 2 6 1 5 8 7 4 2 3

This make sense V8 makes power at every 90⁰ of its rotation 45⁰ phasing will help to make power per revolution also putting more horse power engine at front and less horse power engine at back improve efficient crank loading u should use u joints or rubber coupling to connect both engines together if there is torque difference between drives there is twisting moment happen in drive shaft if u connect both engines side to side there will significant increase in horse power that means combination of two side to side engines coming in single shaft and torque will be 2.5 times

GMC actually made something similar to this for a while. For big vehicles like fire trucks they made a v12 engine which was basically two 351 v6 big block motors put together. I think they used one block but had 2 standard heads on each side. Those v6 engines were made from 1960-66 so I think the same years. It's called the twin 6 v12 if anyone wants to look it up.

Copied from an article on them "Contrary to popular belief, the Twin Six was not the simple union of two 351-cubic-inch engines welded together. The Twin made use of a unique single-piece block and one-piece crankshaft, the latter of which weighed 180 pounds. The Twin Six operated as if it were two separate V6 engines, however-it utilized four cylinder heads, four exhaust manifolds, two carburetors, and two distributors."

Wild idea fellas

There is a guy here in town where I live that has a third gen Camaro with two Big blocks in it. One in normal location and the other in the passenger seat area. The two engines are connected using a V-drive gearbox from a speed boat that has been modified with another output yoke that's connected to a drive shaft that goes to the rear differential like any other camero would. It's freaking wild! He said it's like driving any normal car other than having a four or five hundred horsepower big block as your passenger instead of another person. He will openly admit that he has no idea what it will do because he simply hasn't got the balls to try LOL.

@@BubbaB43 V drive is a popular way to mount them side by side also. Front to back I've seen done with two sprockets of equal size. One mounted to the flywheel of the front engine, the other to the balancer of the rear engine and a double roller chain wrapped around both sprockets. Seems like less mechanical interference than the rigid spline that way too. There will always be some misalignment and that's why a coupler with some flex needs to be used. I think the shaft setup they have here would lead to early crank bearing failure.

We used to race Nostalgia Eliminator #1 and back in the Goodguys days, Mike Kirby ran Sissel's twin six car regularly with two 250 style injected sixes inline for consistent 7.50 ets. Another twin six was the Clarke and Alred Twin AMC car from the same era. These were actually Late 60s comp eliminator D Dragsters running on a loophole in the rules for a few years. Then there was Jeep and Ronnie Hampshire who ran twin F85 Olds motors with custom 180 degree cranks in them, The Odd couple ran a Chrysler and a Small Block inline, John Peters and Bob Muravez ran the freight train out of Venice CA, there was a car with twin Pontiac Tempest 4s inline (1/2 of a 389 each) called Eight The Hard Way, Donnie Hampton even had a Corvette funny car with side by side twin small blocks. Thats just a few. Whenever I see a twin, I cant help but stop and check it out, they just scream cool!

Crankshaft torsion on the output engine is probably a factor in the total power output. It'll be interesting to see if phasing makes any noticeable difference but with 16 cylinders even an odd fire engine will run pretty smoothly. Maybe a flexible coupling between the two would make more power just because it would help with softening the firing pulse harmonics. Good job guys it'll be interesting to see more results. Thanks

He had a single distributor between the engines made from a Jag V12 piece. He would change the firing order to match how he phased them, then go make another pass. I can't remember the results because something failed (distributor drive setup/engine coupler?) He said it made a difference in power, but I don't remember details. Pretty crazy street car.

That said, the phasing of the stroke can greatly affect vibrations here. phasing these engines 180 degrees apart would likely help with crank vibrations.

I worked on several multi-engine cars before. SBC 302 CI / 5 Liter engines were connected to 6 speed transaxles. There was no hard connection between engines. One engine / trans in front, one engine / trans in rear. Front engine placed engine first with trans in front. Mass of engine closer to center of car. Engines synced electronically. With no drive-lines used, no tunnel in cockpit. Both considered mid-engine, because engines sat behind wheels. If we do decide to hard link engines together, we will add a clutch so one engine can be running, the other not running. Better gas mileage around town, and we can alternate what engine is running. This spreads wear more evenly. Car has 3 modules; cockpit, front power, rear power units. Each power unit has everything needed to run, including fuel. Entire power module can be swapped in under 5 minutes. Pull into the pits, get fresh engines, new tires, and fuel, leave pits ready for next hour at Le Mans. End result 4 WD / 4 WS with over 2,500 HP. Since each engine was only producing 1,250 HP reliability was increased versus 1 engine creating 2,500 HP alone. Engines were using twin charging: two screw supercharger on engine being force fed large amounts of pressurized air from turbochargers. Able to get much better linear power curve than with turbos alone. If turbo spins twice as fast, it produces 4 times more pressure. Resulting power curve increases exponentially. Combo helped tame engines, even good at low RPM on the streets. Not bad for a 5 Liter engine making 5 HP / Liter. This prototype is good for 300 mph / 483 kph plus. We have a BBC 4 engine prototype with over 10,000 HP. It is good for over 500 mph / 805 kph. Waiting for Michelin or Goodyear to supply tires that won't melt or fly apart. Tires are the limiting factor for Landspeed applications. When building identical engines, you will never get exactly the same power. You can get pretty close though. Even running same engine at different times of day will result in different power output. Shop temperature, barometric pressure, fuel temperature, etc can all effect power. Remember IROC.... identical cars and engines. Engine supplier was able to match them within 5 HP plus or minus.

This is something i've been interested in seeing done professionally for ages. Even had schematics and some drawings laid out back in the latter 90's early 2000's. I've a 1973 Delta 88 Oldsmobile, the 4 door kind that if you rolled all 4 windows down, it looks like a stretched 2 door. I had it planned out to pull the 455 out and modify the vehicle into a 2 seater, basically eliminating most of the trunk, putting the dash and drivers seat basically just ahead of the rear wheels and transplanting 2x 455s under an extended hood for that vehicle. I even had a crazy heavy duty electric clutch on hand that would fit between both engines allowing me to operate only one if need be (obviously the one closest to the firewall) and allowing me to fire up the 2nd one on a whim and locking the clutch. the Clutch is something pulled out of a john deer combine that is used to engage the rotor, which is designed to take one hell of a snap as well as an insane amount of hp/torque, so i knew it would do the job nicely and is heavy enough not to be a problem not to mention it's designed to attach basically directly to the engine anyways. Unfortunately the project was backburnered due to the family circumstances, but i still have the vehicle and most of the parts. If everything went together relatively well enough that it looked like a professional paint job would do the trick for making it look relatively "stock" minus the obvious shortened cab and lengthened hood, we'd leave it that way, if however a lot of modification had to be made and we started running into constraints in terms of mangling the body up and making it clearly obviously not remotely concealable, we would drop the rear differential on it, and put a 1 ton dual or even a tandem axle under the back end, start welding random scrap metal to it in a relatively appealing way and keep it roughed up paint wise so that we could drive it around as a Mad Max vehicle.

You've doubled the parasitic loss by connecting two engines. I'm surprised the power only dropped that much. Each engine is pushing it's own loss plus the loss of the other engine. Great work!

I'm sure Frankie was secretly hoping his made more #'s while Pat knew he wouldn't be outdone lol. I hope y'all try to tune them more to see if you can exceed the separate #'s. It's the same principle as all the other projects. Yes I know they did before putting them together. So what's next with the twins? Nitrous? Blower? Top fule hats X's 2? Hmm 🤔

17-10-22 The Frequency Of Vibration Well done to all of the engineers who put their time, effort and knowledge into this video on performance-matching ICE motors. It was viewed with interest, as I was expecting the outcome to have been with lightning and people ducking for cover as the coupling failed. I have seen what happens when a lathe chuck key falls on a spinning chuck. At the speed of a jet, the chuck key shot across the workshop with a great lot of kinetic energy, missing the machinist by an inch. The incident left the lathe operator shaking like jelly, with a dazed look on his red face but luckily he had no blood loss on that day. A prior warning of the potential danger was ignored. Remember - Prevention is better than cure. Accidents happen most often due to negligence. I would like to see another test by the engineers in PowerNation. That would be an ICE engine against an EV motor. I designed the concept for the PRIUS Hybrid EV and then the TESLA all-electric variant, but before my work was completed it vanished from my home, so I boxed myself in my home and stopped designing things, while I lived in fear for my life because much of my work was of a technical nature and I did not know who had it, but my work on vehicle technologies has resulted in many wonderful things coming of age. Although I am not known for my achievements, it is nice to see experiments with motors performed by people who care sufficient to do it and make the results of their work available for like-minded people to see and enjoy such tests, which I certainly did as I watched this video. I believe the addition of a safety screen, for use when testing power trains with direct coupling, would be worth considering, as metal travelling at high velocity can ricochet off walls, floors and ceilings in a split-second. From my observation, the addition of a flexible coupling, to relieve torsional stresses between the crankshafts and longitudinal misalignment, would be worthwhile. Also worth considering, is the tuning of the exhaust pipes, starting by making their lengths evenly matched. A temperature reading of the coupling could reveal where energy is lost in miss-aligned shafts. Vibration sensors could also help to determine where power is being lost. The frequency of vibration can be used to detect faulty bearings, as well as earth tremors, and the forces generated by them are great, although unseen until it is too late.

@MachineDr. 2 жыл бұрын

That was very interesting to me. I am glad you mentioned the phasing between the two engines. I never even thought of that.

@markrounds6302 2 жыл бұрын

There's no replacement for displacement. Would like to have seen a run with 45deg of phase on them to more distribute the ignition of the cylinders. That might introduce more stress on your coupler, but instead of doubling the impulse on each cylinder firing it would distribute the impulses more evenly across the rotation of the engine. A lot of theory in what I just said, but curious on how it would translate to an actual dyno run.

Great video guy's on a fascinating topic. I can only imagine this setup in a powerboat cruising offshore racer style. Those are nice power numbers and would even be awesome in a monster truck chassis with front end rear mounted engines. You couldn't run them coupled together but they are so well matched that they would be great in a monster truck chassis.

@Chris-yy7qc 7 ай бұрын

So by synchronizing the firing order what they did was basically make a V8 with double the displacement. I wouldve gone for #1 cylinder (of the second engine) firing inbetween #1 and #2 of the first engine. So you effectively make a V16 with double the power strokes per revolution. Wouldve been interesting to see both concepts head to head.

A thermal imager would be a fine instrument for your shop. Your joint between the two would not fail without getting warm or hot; you could monitor with one as you ran it somewhat under load for instant results. Also, I think the percentage of loss must be relative to a vibration that must occur between the two; believing it is near impossible for a limited budget to bring the two engines to perfect alignment...assuming your budget was limited...

@selmirikanovic 2 жыл бұрын

This is cool but you should check tractor pulling, they are coupling up to 8 or more V8 big blocks, two or more large V12's, V10's, airplane radial engines...all on a single diff to power the big rear wheels. That is next level crazy.

@timteecvhn 2 жыл бұрын

Tbh I'll just say this: You want coupled engine madness, Go take a look at one of CarsandCameras' builds that they did awhile back. Of which was a triple engine minibike. It's initial config was also set up as a three seater minibike too before they turned it into effectively a long drag minibike with three engines. They've also done a 4 engine gokart that had an engine per wheel. Which... as you can guess... was also madness. The only good thing about such small engines is that... They don't make allot of power usually out of the box, but they can definitely handle a decent~ish amount of power out of the box if you do some shenanigans to make it work out.
