Got some engine updates today! These photo's are of crankshaft and clutch being balanced. Also some pic's of the rod's being weighed. I know that the piston's have been weighed and matched ready for the build.

I wonder what the reasoning would be for not allowing a "welded in" roll-cage car on the public roadway? Perhaps just wanting to keep fast race cars from multiplying on the streets and highways? Great build!

Strygaldwir 08-11-2011 07:11 AM

Roll cages and unhelmeted heads don't play well together perhaps?

Flieger 08-11-2011 10:29 AM

Bolt in are closer to driver than weld in.

JEM911 08-11-2011 01:12 PM

unfortunately our roads and traffic authority in NSW, Australia, is well... S#$t. They have adopted a zero tolerance approach to just about anything modified. The reasoning went something like this:

' If we allow modified vehicles on the road, and these modifications aren't done correctly the vehicle may perform worse than the factory specification, thus unsafe for driver and the rest of the community'

that's the essence of the concept. unfortunately a few too many idiot built backyard cages etc, were involved in accidents, and subsequently the "cage" was at fault. It's a great example of how they use misguided statistics to validate a view. By this I mean if you have a traffic accident (assume a minor rear end collision), yet you had a front roll cage, the cage would be a contributing factor. Forget the drivers stupidity, you have a front cage therefore your vision is impeded, so its the cage's fault.

Go figure?

(it's a raw point from my perspective)

So I got the external body work images today.

The body has been walnut blasted, and then hand finished. It's great getting back to this stage as you find any potential issues before the paint and it all become too late to deal with.

Flieger 08-12-2011 10:02 AM

So if you went to the authorities and told them you wanted to install an FIA certified cage in your car to protect yourself from the other crazy drivers out there, they would tell you to bugger off and drive your classic with minimal protection from the thin pillars?

sc_rufctr 08-12-2011 10:10 AM

In my state you can only have a half cage (only from the back of the seats, back)

Yes! How stupid is this system?

There are three essential 'issues' they have with the roll cage.

1. The cage running down along the A-Pillar would 'block your view' - so you can't drive safely

2. The cage intrusion bars protecting driver from a side impact are unsafe because in an accident they will crush you, and you will die (or some similar stupid logic)

3. A cage in the front near the firewall etc will also kill you in a accident because it will crush you (see comment on point 2).


It's the dumbest approach is the world. It's really driven by people who have done dodgy cages, then been in accidents. They don't think as far motorsports success with using cages to 'survive', only the fact that in an accident, done wrongly will impede you chances of surviving.

rexav8r 08-12-2011 02:42 PM

Fantastic project !! Would you do the same for my '78 SC ??!!

Question: When you balance the crank and clutch like this, what are you trimming into balance ?? It would make sense to my feeble brain to shave the clutch since you will eventually be changing that down the road...

Basically body and engine are being worked on at the same time.

The body should be ready for paint (at least the undercarriage) by next week as well. This looks like it will start to come together at the perfect time.

You might want to check a bit further with some of the Sydney Porsche shops - If what you say is correct, then how do they get GT3RS's registered in NSW? They have a full cage with only the side bars as bolt in.

The side bars are generally not allowed to be welded in as the view is they impede access and egress in an emergency - same reason you are not allowed to wear full harness seatbelt on the road.

Would love to see the car at a Porsche Club of NSW track day when it gets here.

Im pretty sure they are registered with the back half of the cage and the front section and sidebars bolt up.

JEM911 08-23-2011 02:15 AM

I'm fairly sure that this is the case as well.

The rules from what I can see are very difficult to deal with. IE certain front cages could get approved - such as those hard up against the firewall. But these cages cannot connect to the rear - only by bolt in for these sections...

Also newly manufactured and registered vehicles have it easier in a round about way...

The joys of the RTA in NSW.

Update from Patrick Motorsports
 
So, my project has been deemed worthy of the Patrick Motorsports website. You can visit the link

http://www.patrickmotorsports.com/project/57/http://www.patrickmotorsports.com/project/57/

Most of the images I have posted are on the forum, but there are a couple of things that have been left off.

Hoping to have the long block pictures to be posted later this week.

The probably best explanation is on the Patrick Motorsports website:

Patrick Motorsports - 1974 Carrera RSR Twin Turbo

Essentially because we have to fit the 993TT engine (including inter-coolers), you need to fabricate a 'new' deck-lid with clearance.

will hung 08-25-2011 04:05 AM

I see. So it'll kind of be like a whale-ducktail. They flatten the top to clearance the intercooler. I figured it had something to do with the intercoolers, but was just curious. I wasn't sure if they'd use the OEM routing of the intercooler, or if they'd take Ruf's routing and lay the intercoolers on either side of the engine inside of the engine compartment. So I see that they'll be using the OEM routing.

Fantastic project.

Flieger 08-25-2011 09:50 AM

So they are going to cut holes/slots in it later?

I have seen 930s with custom bent/cut+welded intercoolers that fit under normal ducktails without shrouding.

JEM911 08-25-2011 05:57 PM

There will be holes cut into them eventually once the final gaps are all sorted on the body.

It's better to get the most efficient design / layout for the engine, then get the body to fit afterwards.

Paint has been a pain in the ass. For some reason the slate grey code seems to be different from a few different paint companies. There's a bit of difference, but I'm close to getting it right.

At the end of the day I don't really think it's going to matter, as the car isn't original in any event, but I do want to get it as close to right as possible.

The set back with color has put this all back a bit. Hopefully we will be on track this week.

JEM911 10-05-2011 01:55 PM

Test fitting prior to paint
 
So because we needed to cut out the duck tail, and it obviously needed to occur prior to being painted, the car's been back in fabrication getting the last test fit prior to painting.

The long and short of it all is that we've moved the engine forward as much as possible to get clearance on the inter-cooler. We also need this because there isn't a great deal of room for the exhaust back there, so it's a lot easier to do the test fit now, without the worry of paint than after paint has occurred.

Also it was decided that we should prepare and test fit all the oil lines etc now, include fabricate any brackets, clip spots, etc, so they all get painted and look as factory as possible.

The long and short of it is that it's not seeing paint this week.
