Next you'll be telling me that they are manufacturing engines that have valves in the heads

An interesting experience last night visiting our engine builder.

He also does V8 Supercar stuff and has some new engines in the shop, both to me look identical and he confirmed the blocks come from the same source. The interesting bit? They are not all for Holdens... yup, seems the new engines like the other drivetrain bits are the same regardless if they are Ford or Holden, only differences seem to be the engine builders detailing to squeeze the maximum neddies from them.

You mean you didnt know that? Now I AM surprised. I thought everyone already knew they've been doing that for a year or two now.

I been thinking, I reckon the nest BIG thing will be the crank at the top of the block and the heads at the bottom, they can get all that air as they power along

Henry already did that, before he decided to go with that old boat anchor between the rails of your old dinosaur. Although the crank was in the middle with 4 cylinders in one V pointing skywards and the other 4 cylinders in another V pointing downwards. Apparantly they had trouble with excessive oil consumption.

The Volksy gang have recently used a similar theory but with bot Vs pointing up forming a W. It's a very effective trick with the 12 cyl version being not much more bulky than a regular 90degree V8, albeit a tad more powerful.

Yeah, but one of the key reasons they gave for not allowing us to play in their game was that we don't have our own five litre pushrod V8.

Fact is we do and not only is it very pretty it makes a mountain of mumbo too. However since I don't know the name on the pic that Brootal stuck on his web site, you won't be able to see it here.

So in the mantime how about a few sets of polished (to releive surface tension) titanium exhaust headers. The three into one pipes are because there's three exhaust ports per cylinder, as there are exhaust valves.

www.the-rumbler.com/carps/v8debate/Pipes.jpg

The reason for titanium becomes obvious when one see's the little 3 litre V10 making around 900hp on the dyno. The reason for the backfire is because this run was a simulation of a full race at one of the tracks to be used this season. The dyno can be programmed to run the engine thru any race at any track that's programmed in. gear change points can be adjusted on the computer to simulate driver error or whatever. This engine is downshifting for a corner, hence the backfire. The reason for titanium is because it copes better with getting white hot, compared to stainless, however one set of headers still only lasts one race weekend.

My crank is above the cam and the heads on the side... is that close enough?

Carps... sometimes you amaze me and other times...









The reason you're having problems Carps, is that you've saved the file with a "space" in the filename. To make the images display, you have to replace the "space" with a "%20" in the URL.

Next time, don't put the spaces in the filenames and you should be right.



...or... you could just leave it to an expert.... ME!

And we all know that EX is the unknown quantity and a SPURT is a drip under pressure.

Geez...We should call you guys Felix and Oscar......Carps got me all interested but neither of you guys can show a picture...
On the subject of upside down engines...I recall seeing a picture somewhere of a sidey V8 upside down in a dirt track car taken years ago. There was also a pic of one with inlet and exhaust swapped over. Looked wierd. Also I recall reading one that revolved backwards as well.

Not sure what the problem is there Carps as I could see them fine. Can't see diddly at the moment though as the website is down. Maybe that's what the problem is come to think of it... They were working earlier in the day, but I see you checked it at 9:31pm. I'll send an email to my webmaster and get him to check it out.

The Zeta Lightburn had an engine that ran backwards. When you wanted to select reverse gear, you simply left it in forward gear, and turned the ignition key the other way and ran the engine in reverse. A real pain to drive, and at 350cc it was a little underpowered too. Hasn't technology come along way...........

I recall back in my PMG days, we had a fleet of Galants, Corollas and Hillman Hunters..They regularily ran backwards after you turned the key off...The record was the Hillman...it ran on for over a minute and gassed the whole basement out. The only way you could stop it was to throw it in gear and drop the clutch. Thats how I figured they were running backwards. I put it in first and when I dropped the clutch it jumped backwards.
