all the old land speed record holders had massive engines. i know one was 18L and i think another was 22L, and they were only putting out much less than 1000hp. there was the sunbeam that was the 18L one. it was a v12 putting out about 350hp. that's the main one i remember.

i also remember seeing something on a show years and years ago about some sports car in the 20's i think it was that was had a supercharger that used to kick in like a turbo and because the tyres were so skinny and crappy it would about spin the car around because it nearly doubled the power in a very short period of time. it kicked in at somewhat high rpm so you were travelling at speed when it kicked in.

i also have somewhere some info on an old bugatti or bentley (can't remember which but it started with B and was from the early 1900's) and it had a straight 16 engine.

I'd be interested to see how fast it would go on the salt flats.

It's got enough torque to pull a stonehenge megolith up a mountain.

Anyway it must be mad to drive because of the lack of grip, brakes, and total mechanicalness of it...that and the insane torque.

top speed is quoted at 168mph. very low revs and high weight would slow it down a bit. i really don't think the torque would be too much of an issue though. sure it only has small tyres, but heavy weight over small tyres can actually increase the grip. plus i doubt the engines are that responsive. if you were to simply stop the accelerator i doubt it would simply fry the tyres like on a modern high powered car. also the gearing would be pretty tall (once you take into account tyre size).

Unfortunately, the article is wrong. It is not a V12, it's actually a straight 12cylinder.

If you look at the picture, there are 12 exhausts on the side of the motor. If it was a V12, then there would be only 6 exhausts on the side of the motor facing the camera.

:D

Nope, its def a V12. The old packard boat engines have 24 exhaust pipes, 12 on each side. They also run in the opposite direction to road car engines (same as aircraft engines) so that lumbering behelmoth must have a primary gearbox hidden in it somewhere as well. Awesome engineering.

nah it says that have the bently speed 6 rear end in it, reversed. so they probably have the diff (or at least the internals) in upside down to get it to run the other way.

and yeah, it says in the story that it has 24 exhaust pipes. second line of the second paragraph.

I'd imagine the top speed is limited by the effective final drive ratio rather than power.

No that I'd feel especially safe doing 200 mph in that car LOL.

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
