The way it looks to me is it's a cast crank because of the thin parting lines. What do you think dangerous?

You think Jim? I am not sure of coarse, just thought it wasn't finished machined in the journals?  Looks like the case machining behind it kinda? I can't imagine a engine of that type having a cast crank, it couldn't could it? Happy New Year Jim look forward to seeing you this year!! |

the following is a quote from their web site http://www.pro-machining.com/news.htm"The engine block has been machined from a 70 kg aluminum blank while the crankshaft was crafted from a 450mm long, 160mm diameter piece of high-tensile steel. Anderson said it had taken 15 hours of machining to make the camshaft from the 69kg blank." |

Mmmmm, nice!
I cant see any support for any lifters and no lifter holes. Is it OHC?

Yes that line is just what remains from the machining to an equal depth from each side.
That is a masterpiece.
It took me four times that long to do my VW crank to that stage, and it has less mains.

This? I can see an axle with a gear on it. Good to drive an oil pump, vacuum pump, injector pump or???
But I can't see any cam.

Cam has 60mm diameter journals and sluces in from the front of the engine like a regular engine,
but below the crank like a Volksy.
That is where the cam will be I understand.

Weird, my first post vanished...anyways, that is a real work of art, really have to admire the machinist for the amount of time and labor spent on that one. The crank is just too nice to use!

Hi there, I'm the guy that has built the crank and block. Thanks for your comments. Keeps me motivated to get the project finished. I'm actually building this for a local racer "the British Bulldog" (John Trehane) for a midget Currently working on the heads. Will have some photos posted shortly. These will be cast for now but looking at going billet later on. I have been having trouble logging onto the Aussie site which is why you haven't heard a lot from me. Many thanks to "Dangerous Dave" for posting for me. The block is one piece billet 6061 Alum. You don't see any provision for lifters as yet as I haven't got that far yet. Waiting for lifter's before maching. The lifters won't be sharing cam lobes as per stock. Running roller BB Chevy lifters. Cam will be running a 60mm roller with our own adjustable gear drive on the front. The cam you see in the photo was just a bit of a joke. It is one that we make for the late model Triumph motorcycles. Uou can check out the specs for these at http://www.thunderbike.co.nz/shopn/spi/tbike_SCR. We will be making cams for this block also. The crank IS billet as per the news article on our site. The lines that you see are just leftover from maching in two planes i.e. 3D profile on our 4 axis CNC machinig centre. Right now it is sitting in the CNC Lathe waiting for the journals to be finished. It is currently just under 30lbs. Would like to get this going a little sooner, but finding the time is a bit of a problem these days, what with trying to run a business and keep the dollars flowing as well. Oh BTW I'm in New Zealand... |

You can send your check C/- The money pit ....  Nah... in all seriousness this will be available once the prototyping is complete and proven... Hopefully in around 6 months time... |

Pushing the envelope!
I like the five rod bearing set-up. What is the rod bearing width, they look narrow to make room for the extra main ?

WE are using Chevy 2 bearings for the mains and Small Block Chevy for the rods.
Engine is about 1 3/4" longer than stock, to accommodate the 5th bearing. We have been looking at the shortcomings of the stock and other aftermarket set ups and are trying to recifty them.
What you see may not necessarily be our final production. Remember that this is a PROTOTYPE and is constantly under revision.
To date most of the design work has been done via solid modeling on the computer. Saves heaps of time and of course dosh...

Hey Greg, I've reset your password on aussieveedubbers for your promach username. I will email you the new password and once you log in you can change it straight away to whatever you like. For some reason there has been some conflict with email addresses and logging in (there is a sticky thread in the general chat section explaining it) - I'm not too IT technical savvy so can't really explain too well! Email me on alanagyik@hotmail.com if you still have problems logging on. Lovely work on the block by the way - I can really appreciate the time, persistence and experience required to get something to that stage. Alan |

Hi Greg,
Did not know that you were doing this on my back doorstep, Im in Auckland Looks good. Seems like there is a bit of action in the midget car engine area at the moment in NZ. Yours and the kawasaki V8. I am interested! Keep it up.
Regards

Don't think I mentioned it here, but I'm not doing this project on my own. I'm working in conjunction with a local racer and good friend, JT (John Trehane). He has the car and I've got the equipment. Were both putting our heads together to make this project work.
JT has just finished the grunt work for the pattern for the heads. Hope to get this to the foundry over the weekend. It will be about two weeks before we get this back. Jt's got itchy feet to go racing again, so gotta keep things moving.

Yeah the 5 MAIN thing is what REALLY puts it over! This is what Larry Kelly needs to check out for his future engine project, to be able to spin it up 10K plus and not self destruct, 5 MAINS. |

It's like they say--if it was easy, everybody would do it!!
Take it from someone who knows. I'm with BRE in the US. It took us many years of refinement to make a big motor work. We are now running a full 90% load of blown NITRO and not seeing any bearing problems. We believe we are making hp in the 3000 range.We can do it with just 4 mains, imagine what you could throw at 5

Here are some progress photos of the Crank. Only needs oil holes, lightening holes through bigends and heat treating/grinding now.
We have managed to get the weight down to 25.5lbs / 11.59 kg.
The head casting shown, is our second option and has been supplied by Joe Deppe of Indy.
The head casting of our first option will be ready next week. Will have pics then.

As Dave said"Masterpiece". Is there a possibility of producing high performance cranks in various strokes for T1&T4 engines..??
This could be another alternative for buying a really top notch crank, and coming from NZ, it could be priced rather competitively too!

Thanks Craig for your comments. We would consider making other cranks providing there was a market for it. No point in putting all the work into something for just onesis. If you can drum up others who would be keen then I'd be willig to look into it. The more I make in each batch the cheaper the unit cost is in the long run. I'm not being arrogant, but we can make pretty much anything... You can check out our website for capabilities at www.pro-machining.com |
