Carryfast there are 47 variations and types of R1820, you are getting partial information from limited sources. The one’s you are referring to are the model r-1820-G2 and the R-1820-f-52 the two models used in the early Sherman’s. In the spring of 1949 the first R-1820-82WA based diesel conversion was tested at Crawford Texas. It was later put into production rated at 450 hp used in production of sherman’s marked for service in Korea. The R-1820-82WA were the last mods used for the B17G. At present we have 2 operational B17G’s and a B17F currently under restoration. I have also assisted with the restoration of the Liberty Belle which if you know anything at all, will know that is the bomber used in the filming of the Movie Memphis Belle. I am a lifetime member of the Commemorative Air Force . Texas Raiders is currently getting a main spar overhaul and will be have its first test flight in May or June. Texas Raisers saw action in England during the war, and was involved in many missions over Germany. I deal more with Sentimental Journey which is Stationed at our squadron at Falcon Field in Mesa Arizona. I case you didn’t know the R1820 was also used in the DC-3 model numbers 1820-76A,B’C’D versions. I wont go into the differences as it would be way over your head. Let us just say you have very limited knowlege on this. Oh and I also worked as an advisor on the restoration of a Mitchell Bomber, a spitfire, P40G, Tiger Moth and a variety of other aircraft. I have not always driven a truck for a living.

Saab have always dared to be different.Different yes.Better no.Which is why anyone who knows anything about cars would’nt rush out to buy a SAAB if they won the lottery.
It’s more likely (rightly) that it will be something with a front engine and rear drive unless it’s a Veyron.
Obv not a Saab lover then, I’m on my 2nd Saab, I’m running 225bhp and I havnt had problems in the snow, yet a similar powered BMW 3 series couldn’t even move on the same patch of ground as me, your argument about a Ferrari vs a Mondeo is reduce though a Mondeo probably would be better than a 550 in this weather, when it’s dry the Mondeo would be boring, I’d still prefer a heavily tuned rb26 stuffed into a jzx100 than a Ferrari
But the relevant comparison would be the Mondeo with as much power as the Ferrari or even an ST 220 in this weather if we’re comparing like with like.Reduce the power with rear drive and you’ve got the advantage of something that can still steer while it’s losing traction unlike a front driver.Which is why one of the best cars I drove in zb conditions was a rear drive Volvo 145 estate.
but your argument is still flawed as the 550 has around 500bhp, whereas a mondeo has about 140 on average, im saying to you a similar powered bmw against my fwd saab is rubbish, the only problem i have with my saab is the stupidly fat tyres on it which if i had a set of winter tyres on would be brill.They dont build volvos aswell as they used to. when the snow started here all the rwd cars got stuck then ended up blocking roads because they went sideways, the fwd cars just got stuck in their own lane remember the rwd cars dont have double drive of diff locks
this is the only time when rwd is fun

Limited sources yeah right.Like a WW2 vet (my late dad) who served in Italy in 1945 in the REME on tank transport and recovery. and all he said,to cut a long story short,was the same as what I said and if you check out the history of the Sherman it seems to me that he was talking about the Continental radial not any designation of r -1820-G2 
and the inline six cylinder Detroit two stroke diesels and 1949 is 4 years after WW2 ended.So in this context soldier x got it about right .Although neither of us are wrong and if any modifications were needed on the Sherman’s engine space it’s more likely that it would have been needed to fit the inline Detroits not any of the radial types which the thing had been originally designed for .But saying all that a lot of lives could have been saved if they’d had the Comet a lot sooner and just left the Sherman as a supply of engines for Flying Fortresses 
.Although it’s ironic that the only radials left for them now seem to be diesel conversions of the radial petrol motor which then have to be converted back into petrol spec.

As I said limited.
I have the spec sheets here, and copies of the blue prints, for all 47 mods as well as the information on the conversions. I also have a partial list of serial numbers and in what units they were issued. Alot of research goes into this, from manufacturers archives as well as war department documents. That is how we are able to identify, aircraft or partial aircraft that are found. Now if you really want to do some good there were 45 R-4B Hoverfly Mark 1’s shipped over to England in 1943. The engines are Warner R-550-1/3, 10 spare engines were shipped the same time. Your mission if you have what it takes, find one with gearbox. We have one at our Texas squadron in need of parts, other option and much more costly is to make the parts from the blueprints I have. Have you ever tried to hand make a part for a vintage engine like this ? I have.
I give up of this forum - this’ll be my last post. You cant even have a light hearted thread without the man who knows everything (well as much as youtube and Wikipedia can provide) sticking his oar in spouting ■■■■■ about nothing relevant.
Have fun boys,

Zb typical.I point out all the bs which all the front wheel drive boy racers come out with to trash decent cars and then someone else brings Sherman tanks and planes into the topic.Then I get blamed for it all. But in general trees don’t argue much about the proven superiority of rear drive cars because they’re more intelligent than the average front wheel drive hot hatch driver.Although the frightening thing is that there might be an AC Cobra owner out there who believes all the front drive bs and is right now taking hundreds of thousands of poundsworth of value off the car by having it converted to front wheel drive.
Curry face if a cobra driver converted it to fwd he shouldn’t own one, a cobra driver wouldn’t drive it in the winter, that’s what his fwd or 4x4 is for so he doesn’t damage it, cobra are brutal with a 7 litre v8.
Your totally misunderstanding what were are saying, rwd in the summer and a PRACTICAL car eg fwd/ 4x4 in the snow.

But it’s the advantage of having rear drive that makes that 427 Cobra driveable in the first place and it’s that same issue of trying to transmit comparable amounts of torque through the front steering wheels which make a front drive car more of a handful in bad conditions than a rear drive car is on the limits of adhesion.Which is why I preferred that old Volvo 145 in zb conditions than the 1.8 Zafira which I use around town now while the V12 TWR Jag is asleep in the garage. 
Wood fuel,
OK mate, realised after I had posted…no problems.
Just wondering, would there be so many BM’s and Mercs stuck 'cos lots are autos.
I’ve only ever owned one front wheel drive car (and I’ve had lots) and would still prefer a rear wheel in the snow.
As I said earlier you can stick a couple of bags of sand in the boot to maintain traction.(or a Merlin engine)
But , there again, maybe thats 'cos I’m a proper driver
(ducks behind the barricade very sharpish )
del949:
Just wondering, would there be so many BM’s and Mercs stuck 'cos lots are autos.Del, if that’s refering to my earlier post (before we were forced to re live the battle for Iwo Jima) you may very well have hit the nail on the head. It’s not something I considered TBH. Still prefer my theory that all the drivers are Richard Edwards though.
Well we normally get a heck of alot more snow here than you do there. IT has more to do with the lack of ability on the part of the drivers than on the cars themselves. Then again the images I have seen on this thread I dont consider that especially heavy snow. I am in Western Canada I have 2 cars a Mustange Cobra convertable, and a 1965 beetle I drive them both,the beetle less than the convertable. Driven front wheel and rear wheel drives dont seem to have the problems with any of them some posting here do. The again we have snow here 7 months of the year. Its about as stuipd as some of the arguements saying women are worse drivers, sorry not true men have the attitudes most of the time not the ladies.
Brentanna:

I think you’re right there, but it does also make a difference if the engine is over the drive wheels.
I’ve 2 motors about me, an Audi A4 Avant with very wide tyres… it has stayed in the garage recently, and an ■■■■■■ van, which I’ve been using. Heavy diesel engine, front wheel drive & not too wide tyres, goes anywhere. I set off in 2nd in the snow & I’ve hardly even had a spin on yet.
In 1981(?) when we had a lot of snow, I was working for a main Ford Agent at the time. One of my duties was get new cars started and out of their parked lines in the yard as they were required for PDI & delivery preparation. It was very noticeable that Fiestas & Escorts (FWD) would go anywhere, whilst Cortinas & Capris (RWD) you might aswell not even bother trying. Granadas (RWD) were slightly better due to the extra weight.
I think autos are better in snow as you can apply the drive take up & acceleration more smoothly.
(I’m talking about automatic cars with a torque convertor, not trucks that have the same manual gearbox with a computer controlled air operated change).
Right then, although it pains me to say it I’m with car… carry… carryfas… Nah, I can’t do it, I’m not putting the words agree, with and carryfast in the same sentance, they will surely come back to haunt me 
On a mechanical square bore engine, his theory and science are correct, alter bore or stroke though and torque/power changes.
On an electronically controlled engine you can set power and torque to wherever you want it and you can raise and lower values of either, so even though he’s correct, it’s a moot point.
I like them a lot, but Saab’s are crap, the current one is built on a Vectra platform that was obsolete in the Vauxhall range years ago, they look nice (unless they’ve got that chrome crap around the lights) and they’re different, but from a driving standpoint they’re seriously flawed. They were owned by GM, but I think they got flogged off in the Bail Out fiasco, I remember reading that Koenigsegg were going to buy them, but I think that fell through.
FWD cars with over around 180hp are undriveable without fancy electronic controls and trick diffs, so are 4WD cars, your Quattro’s, Subaru’s and Mitsubishi EVO’s all handle brilliantly, but that’s down to technology, try doing the same in a Mk1 Land Rover, even one with big tyres and stiff suspension and you’ll end up in a world of pain The simple way is the best way, front wheels steer, rear wheels drive, it doesn’t matter whether the engine is front mounted, mid mounted or rear mounted, that’s what method all the world’s best handling cars use.
Now, having said that, if you want to get along in the snow, it’s FWD everytime, so carryfast, you’re WRONG…As usual
NMM you had me very worried at the start of your post.
My rwd convertible stays in the garage all winter,no I don’t want it covered in crap from the roads but it’s also too low and would belly out.My toy of choice is my wife’s 08 Cherokee,awd system is superb as it sends the drive to where it’s needed,sticks to the road like ■■■■ to a blanket.
Merry xmas to all
I had 4 new winter tyres fitted to my Scudo MPV today. The difference in traction is outstanding. I failed to drive up the hill in our cul de sac 2 nights ago as my summer tyres would not grip on the ice. I ended up driving over tarpaulins, and with help from a neighbour managed to get up the hill eventually. I slid down the same hill earlier in the day too.
After shelling out £675.00 for new rubber all round, I drove up the same hill with no drama at all. I was amazed how much diference it made so I then tried to make life difficult. I went back down the hill and attempted to skid by stomping on the brakes. Almost no sliding at all. Ok, let’s try a hill start on the steepest bit of the hill. I stop on a nice slippy bit of the road on packed snow which has been polished smooth. Gentle start in 2nd gear, and away it goes. That’s no fun. 1st gear, give it some revs. No wheel spin. Fantastic!
All I need to do now is avoid getting too cocky and think I can’t crash with these super grippy tyres.
What may be amusing is having someone who is following me, and on summer tyres, thinking they can drive at the same speed that I can now.
I’ve never bothered with winter tyres in the UK before, but from now on I’m going to use them every winter.
In Canada, winter tires (tyres) are common in most places, but where I grew up on Vancouver Island the climate is generally wet rather than cold and snowy so winter tyres were not common. Big Jon tells me some people where he lives use all season tyres, which are better than our summer tyres, but not as good as proper winter tyres.
The other thing I found out was that Kwikfit will store your summer tyres in bags for you and refit them after the winter. You then leave your winter tyres with them until you need them the next winter so you haven’t got 4 tyres or wheels cluttering up your garage. I didn’t need to store my summer tyres with them as I have space to keep them, but for £40.00 it seemed a reasonable deal as it includes changing the tyres over on the wheels every time.

Amazingly for KF, that does seem very reasonable, assuming they’re including 4 balances in that every time aswell.

I would have thought that a rear wheel drive was better in snow than any front wheel drive.
Mainly 'cos you can always throw a couple of bags of sand in the boot for ballast
But FWD drive cars tend to have built in ballast, you might call it an engine mind you.
On Saturday afternoon I ran a friend to work, from Luton to Hertford as she had misplaced her glasses and didn’t feel confident driving without them. My car was in for MOT so we used her Toyota Yaris, FWD. It was snowing hard, so hard that just as we were leaving they abandoned the Luton Town match because of it, and that little FWD, automatic, Yaris had no problem in the snow at all. On dual carriageways I was using the empty outside lane, lane 2, to pass all the other cars hwo were nose to tail doing less than 20 mph. On a single carriageway section I came up behind a Mitsibushi Shogun and a Landrover Discovery and while waiting for a gap in oncoming traffic to pass them the Yaris speedo was reading 12 mph! When I did pull out to nip past them the Disco driver started shouting and waving his fist out of the window. ■■■■.
The Yaris is a real fun car to drive in the snow, sticks to the road like excrement to woollen bed covers.
Forget about FWD vs RWD and traction control and the like. A bimbo biffed her BMW into someones house and started crying and it was funny.
