My only concern,is the jack-shaft and pillow bearing setup,that is running the front-ward Charger....those bearings are not great for high rpm applications and those pillow blocks are cast and like to shatter from heat...good concept,but She needs some CNC'd billet pillows and some dual roller bearings(or high speed,sealed w/nylon retainers) and it'll be bulletproof....she sounds awesome!

[@LinusNil]

You are probably right that billet made blocks would be stronger. These have however proven to work fine for several years, and several runs since this startup. I'd say that heat is nothing to be worried about, but if the builder (my friend Olle) asked for my advise, I would probably offer to machine some stronger bearing blocks for him.

[@dwayneowen6262]

I'm real surprised that a single carb on each blower can supply nowhere near enough fuel to keep that thing from starving but I guess it must work. You got a badass pulling tractor !!

[@LinusNil]

A lot of people have had their concerns. Personally, I am not experience enough with engines/carbs this size to tell if it would work or not. All I can say is that the builder, my friend Olle, got it more or less right at first try. And these carbs are really large! And I agree, the tractor is badass. A very nice build.

[@randymagnum143]

I think youre overestimating the displacement and power of this engine compared to 2 800 ci v8. 2 1050 dominators should be damn near enough for 1650 ci at 4500 rpm, and they make up to 1475 cfm if you want more rpm.

[@LinusNil]

@@randymagnum143 Correct. Holley actually recommended these carbs for this particular setup.

[@turbo1438]

Of course it's lean. 5.7L engine needs minimum 750 cfm of air. This thing would need approximately 3500 cfm to operate. So double everything (carb, blowers, and fuel) and it would really run. At minimum a huge 1 inch fuel line and much bigger pump to support this hungry beast. I would suggest a pair of 12v71 blowers with dual predator carbs on each, fed by four Holley red pumps. That big Allison is hungry! Feed the beast!!

[@LinusNil]

A lot of people have been trying to point this out before. Still, it does not run lean. The carbs were recommended by Holley for this specific setup and I seriously doubt they are so incompetent they would recommend too small carbs. You are missing one important point here. This is not running at the same revs as a 5.7L V8, and since the RPM stands in direct proportion to the air flow need (cfm), your assumption is incorrect. With the same cui to cfm ratio but running at half the RPM, the Meteor needs 1762 cfm based on the 750 cfm for a 5.7 L V8 you stated. Two Holley Ultra Dominator can provide 2500 cfm of flow, which is enough for this engine running at this rpm.

[@turbo1438]

@@LinusNil you're right! I hadn't considered the rpm being probably what, 2500? Those engines are often called Allisons here in the states. I have always liked them in pulling tractors and yours is no exception. I guess it just looks a tad small with just the two carbs.

[@LinusNil]

@@turbo1438 Indeed, these engines are incredible! They are huge in comparison to the power output though, but this is common among engines which are supposed to handle high load for long duration of time. Also modern engines used in similar applications (marine, heavy machinery etc) have relatively low power output to cylinder volume ratio. It is relatively light though, being completely aluminum (both heads and block).

As previously said, the Meteor was a tank engine. They were either "flawed" engines that could not go into aircraft or engines recovered and rebuilt from damaged aircraft. As a tank engine they were naturally aspirated, regardless of if they were built as a Meteor or rebuilt from a Merlin which had superchargers. As per usual in the war effort, they were assembled in the Rover car factory!

[@mikeskidmore6754]

Hey @jbbumpkim Many Rolls Royce Merlin engines were built in Detroit Michigan USA at the Packard Car Factory .. They said Packard built higher quality than the British engines were.. In the USA many pulling Tractors use the Allison engine some of the later Allison's had two speed Superchargers and think Rolls Royce had that feature too. Both used Centrifugal vane superchargers not roots blowers like BM made for truck engines.. and heavy Equiptment engines..

[@Slaktrax]

@@mikeskidmore6754 There was no difference between Packard or RR built Merlins, this is a fallacy. Read the book ''The Merlin In Perspective'' from the RR Heritage Library. Packards built their engines to RR sopecifications and were identical in performance and standard of build. People are just perpetrating bullshit.

[@Slaktrax]

@jbbumpkin Not quite. The blocks are different, the Meteor also used a different crank and cams for opposite (CCW) rotation. The pistons were cast not forged and many other parts that did not need to be made to aircraft spec and standards were used. Different animal built at a different factory to a different spec.

[@amazingnation6072]

How does the cardan shaft withstand so much pressure? I always wonder that

[@LinusNil]

You're not alone being perplexed about how these old tractors hold together. The base is a BM-Volvo T 470 Bison. These tractors had a 73 hp engine. The power output of this thing is probably around 1000-1200 hp (maybe more, no one knows). The engine is directly coupled to the original gearbox and rear axle! Just think about it; power has been increased by 15-20 times and the old gearbox and rear axle have no problems dealing with it. Another guy I know has a 38 L Transmash V12 diesel in the same tractor. No problem. Yet another friend did put the same transmash engine in a Fordson Super Major. That rear axle was split in two.

Around 1000-1200 hp from 27 liters is quite tame yes. These engines were built to last hour after hour on heavy load, not for drag racing. Another friend has a 38 liter Transmash V12 diesel. About the same case there. The power output in respect to cylinder volume is relatively low.

RUNS VERY SWEET

[@Romans--bo7br]

Nice looking tractor and a good idea of the roots blowers on the Rolls.... first one I've seen "built" with roots blowers like that. However, I think you're headed for some catastrophic problems "down the road".... if not on your first pull on the hook and under load. 1) I Never would even consider utilizing a "jackshaft" for that application, 2) you definitely should have an "idler" pulley on your main drive belt from the crank, 3) I would never have those fuel lines situated the way that you do... especially in relation to the drive belt, and 4) you should really consider some kind of "guard shields" for all your belt drives... so that when they let go, you can keep the damage to a minimum.... at least, externally. The sanctioning body for your pulls must have pretty relaxed rules to even allow that setup. The idea is Great, but unfortunately... the execution of it... not so much. Why didn't you go with a coupled direct drive setup between your blowers which would eliminate the jackshaft and two belts?? I realize that you would have to have a new end plate cover custom made for the rear of the driven blower between the two blowers, as well as a shaft extension from the crank driven rotor to the coupler, but it probably wouldn't cost you much more than what you probably already have in your current setup with two unnecessary belts, idler pulleys & brackets, jackshaft & bearings and fabrication of the jackshaft pedestal..... and it would be a lot more sanitary setup, while reducing potential parts breakage by at least 50 percent. I would use an industrial flexible coupler... not a slip or chain & sprocket setup, due to the fact that you would have to have 100 percent Perfect alignment between the two blowers to use a Non-flexible coupler.... but a flexible coupler would allow for any possible, however slight... variance between the two blowers. Someone below here, in the comments, asked why you didn't use a coupler from a 16V71 (or, at least that's what they were referring to without naming it).... you cannot do that, that easily. In order to use the factory blower drive setup from a V16, you would have to acquire the actual blowers from a 16V71, because the "rear" blower (the one that is gear driven from the engine) has a special rotor and shaft setup in it, which extends through the forward endplate and coupling with the forward blower. Unless you can replicate that setup, the factory coupling will Not work on your 8V71 blowers. How many rpms and how much torque are the jackshaft bearings rated for? What is your ratio between the crankshaft speed and blowers?.... it appears that the gilmer drive pulleys on the jackshaft are slightly smaller than the driven pulley on the shaft from the crank pulley.... are they over-driven by 10 to 20 percent?? How are you oiling the drive end gears of the blowers?... or are they just "statically" lubed within the end-case, and not pressure lubed from the engine?? I assume that you had the rotor lobes "prepped" and sealed for use with the carbs (and the gasoline) on your draw-through system? Maybe it was the camera angles, but I did NOT see any "burst panels" built into the plenum boxes under the blowers..... if you don't have any - you Will regret not having them at some point... you "should" have Four (4)... one at each end of your plenum boxes.... but you can get away with One in each plenum... sometimes. I wish you well... and good luck with it. If it were me though, I would be doing some serious re-configuring of the setup, Before I would ever put it under load. It would be really sad to see all the hard work and money you put into it.... go "ka - boom" (as if that doesn't happen in any form of motor sports, already ; ). Longevity of the engine... is All in the most minute of details.... and you have some details, that need some "re-evaluating".

[@LinusNil]

This is not a finished build. What you see in this vid is a brief test run. This means that not all shields were in place, the fuel lines not properly routed etc. Also, I did not build this machine so I can't answer all your questions. All I can say is that it has worked well this far. There are burst panels, and they work. Bearings are not rated for torque, but for radial/axial load and RPM. I have checked the numbers and they are indeed running a bit on the limits but it does not seem critical to me. Especially since each run is short so temperature should not be a big issue. Regarding super chargers; I don't know much about these to be honest. The chargers are however rebuilt for this particular purpose. I believe this was done in the US but I don't know much more. Regarding the belt drive, all parts for that one (belts, wheels etc) were selected by the manufacturer/agent of the drive components.

[@LinusNil]

Good question about the gearbox. What's interesting is that the gearbox is an untouched original gearbox from the Volvo T470 Bison. The quality is quite impressive. The engine power has been increased from 73 hp to more than 1000 hp, and both gearbox and rear axle are working flawlessly for run after run. The clutch has been replaced however. The current one is some kind of centrifugal clutch with manual override, manufacture by someone in Finland.
