If it walks like a duck .....

and dresses like a duck.......

Who knows if it's a duck.......    The Boss owns a 1974 Carrera RS.......Original Ducktail.  This Black 86 wants one.

 For years I have been complaining about the poor quality of duck tails that we install but I have never been asked to do one, until now.  Metal based and fiberglass top to mimic the original one.

 

And I must say, what a paint in the rear.  I do understand now why the more affordable ones are of such poor quality,  the hours that are involved in a project like this are not cost effective.  Once you move one thing, everything else changes angles.

So, for us to make this a production item is not a reality, but we do have a couple of orders, some of our clients are very dedicated to their cars and want to have a duck tail made specific the their car.......and that is something to brag about.

Wish list

When it comes to restoring a Porsche 911

We usually get a big list,  sometimes it is all the matching numbers and sometimes it is all the mods to be made...

In the case of this 1972,  it is going to have some serious mods to take the 3.8 engine with a monster air injection and a 6 speed. 

So, this body will have to be reinforced:
1:  stitch weld the tub.
2:  reinforce the shock tower.
3:  rinforce the jack points.
4:  double the inner rocker panels.
5:  weld in strut braces.
6.  weld in section for power brakes.
7:  remove rear tray and fab custom one.
8:  remove rocker panel and fab stainless steel oil lines.
9:  remove rain gutters for a slick look.

151:  prepare for a tripple black paint.

201:  polish to the highest shine...I want to see myself !!

Looks like we have a lot to do yet, but it is coming.
Once the gaps and lines have been matched, it's all down hill from there.

Stay tune...........

It's a wrap !!!

There was a little debate about the pros and cons of wrapping headers.....

Of course, as with every gearhead discussion, things can quickly get out of order...........Last I heard was "I don't want to have a fire hazard in my engine bay"   Trust me, I put fire to this thing, it does not burn.   Any how, after talking to our experts and getting some info from the net,  this makes sense:

PERFORMANCE:  The goal of headers is to make it easier for the engine to push exhaust gases out of the cylinders.

TEMPERATURE:
The titanium wrap will keep the hot air inside the header, allowing for cooling air intake:  cooler intake produces more horsepower, as cooler air contains more oxygen, which aids the burning process in the cylinder.  Wrapped headers can reduce the under hood temperatures significantly.

VELOCITY:
In theory, wrapped headers help contain the heat, making the exhaust gases move more rapidly away from the engine and towards the exhaust pipe.  This increased exhaust velocity increases potential horsepower by evacuating the cylinder more quickly and allowing the piston to move upward with less resistance.

 SCAVENGING:

The gases velocity also helps with the scavenging, or the removal of combustion waste from the cylinder more efficiently.  This makes for a cleaner and faster burn of the mixture of fuel and air on the next piston stroke. 

Rolling down the highway......

....not quite yet, but we are getting there.

After changing everything on this old body and giving it a new face lift, a tummy tuck and some botox, 

A new wardrobe has been added to this body in the shape of 993 interior, gauges and oil tank, a boxster roll bar that has been modified to fit this body

Now we need accessories.......
Sometimes I see my wife looking at a pair of earrings for the longest time, it makes me wonder what the heck I am doing at at the mall, not shopping.

But this is the way you buy rims, they can make your car or .....not

Another thing to consider is that size does matter, as well as offset,  what size wheel to get, and what size rubber........decisions, decisions , decisions,  can't use fuchs wheels, that would not go with our reinvented body

We used one of our  client's wheels to measure, and it was a good fit, but even though the ride is down in a non operating state, the set is not for sale.

We did found the name of the wheel, now the mission is, should you chose to accept it, to find out if it is still available.

When it's all .....LOBE....

 I remember when I was a kid in school, if I had homework, I would have to convince some friends to come with me to the library and then try to get there before other 50 kids with the same assignment get the one book...........decades later, there is Wikipedia.  So, lets talk cams: if your heads need more air to create more power, the valves' timing of the duration of the lift, has something to do with it, it's a "lobe" affair.

History

An early cam was built into Hellenistic water-driven automata from the 3rd century BC. The camshaft was later described in Iraq (Mesopotamia) by Al-Jazari in 1206. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. The cam and camshaft later appeared in European mechanisms from at least the 14th century, or possibly earlier.

Uses

In internal combustion engines with pistons, the camshaft is used to operate poppet valves. It then consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes protruding from it, one for each valve. The cams force the valves open by pressing on the valve, or on some intermediate mechanism as they rotate.

Automotive

Material

Camshafts can be made out of several different types of material. These include:

Chilled iron castings: this is a good choice for high volume production. A chilled iron camshaft has a resistance against wear because the camshaft lobes have been chilled

Billet Steel: When a high quality camshaft is required, engine builders and camshaft manufacturers choose to make the camshaft from steel billet. This method is also used for low volume production. This is a much more time consuming process, and is generally more expensive than other methods. However the finished product is far superior.

Timing

The relationship between the rotation of the camshaft and the rotation of the crankshaft is of critical importance. Since the valves control the flow of air/fuel mixture intake and exhaust gases, they must be opened and closed at the appropriate time during the stroke of the piston. For this reason, the camshaft is connected to the crankshaft. In a two-stroke engine that uses a camshaft, each valve is opened once for each rotation of the crankshaft; in these engines, the camshaft rotates at the same rate as the crankshaft. In a four-stroke engine, the valves are opened only half as often; thus, two full rotations of the crankshaft occur for each rotation of the camshaft.

The timing of the camshaft can be advanced to produce better low end torque or it can be retarded to produce better high end torque.

Duration

Duration is the number of crankshaft degrees of engine rotation during which the valve is off the seat. As a generality, greater duration results in more horsepower. The RPM at which peak horsepower occurs is typically increased as duration increases at the expense of lower rpm efficiency (torque).

Duration can often be confusing because manufacturers may select any lift point to advertise a camshaft's duration and sometimes will manipulate these numbers. The power and idle characteristics of a camshaft rated at .006" will be much different than one rated the same at .002".

Many performance engine builders gauge a race profile's aggressiveness by looking at the duration at .020", .050" and .200". The .020" number determines how responsive the motor will be and how much low end torque the motor will make. The .050" number is used to estimate where peak power will occur, and the .200" number gives an estimate of the power potential.

A secondary effect of increase duration is increasing overlap, which is the number of crankshaft degrees during which both intake and exhaust valves are off their seats. It is overlap which most affects idle quality, inasmuch as the "blow-through" of the intake charge which occurs during overlap reduces engine efficiency, and is greatest during low RPM operation. In reality, increasing a camshaft's duration typically increases the overlap event, unless one spreads lobe centers between intake and exhaust valve lobe profiles.

Lift

The camshaft "lift" is the resultant net rise of the valve from its seat. The further the valve rises from its seat the more airflow can be realized, which is generally more beneficial. Greater lift has some limitations. Firstly, the lift is limited by the increased proximity of the valve head to the piston crown and secondly greater effort is required to move the valve's springs to higher state of compression. Increased lift can also be limited by lobe clearance in the cylinder head construction, so higher lobes may not necessarily clear the framework of the cylinder head casing. Higher valve lift can have the same effect as increased duration where valve overlap is less desirable.

Higher lift allows accurate timing of airflow; although even by allowing a larger volume of air to pass in the relatively larger opening, the brevity of the typical duration with a higher lift cam results in less airflow than with a cam with lower lift but more duration, all else being equal. On forced induction motors this higher lift could yield better results than longer duration, particularly on the intake side. Notably though, higher lift has more potential problems than increased duration, in particular as valve train rpm rises which can result in more inefficient running or loss or torque.

Cams that have too high a resultant valve lift, and at high rpm, can result in what is called "valve bounce", where the valve spring tension is insufficient to keep the valve following the cam at its apex. This could also be as a result of a very steep rise of the lobe and short duration, where the valve is effectively shot off the end of the cam rather than have the valve follow the cams’ profile. This is typically what happens on a motor over rev. This is an occasion where the engine rpm exceeds the engine maximum design speed. The valve train is typically the limiting factor in determining the maximum rpm the engine can maintain either for a prolonged period or temporarily. Sometimes an over rev can cause engine failure where the valve stems become bent as a result of colliding with the piston crowns.

Out of body experience

 It seems like our movie star is going to collect one more part, one very important part.

All that running around making his presence felt has left him clutch less, his powerband does not surpass the 400hp, pity, that is where the fun is.

So up we go, it's time to let doctor operate.

 The "while you're there" bug always pays a visit and the temptation of adding a few more things is gaining momentum, a limited slip and alcohol injection have been on the wish list, who knows, maybe we can proceed to check out

 In the meantime, let's add some real clamping power and keep the rubber on the ground.  We had one our vendors build us a dual face Kevlar disc and a heavy duty pressure plate.......that ought to work out your leg muscles.  I don't think my chicken legs can handle that.

When this ride was called the 75 beast on TV, it really didn't show how wild of a beast it really is,  but here you can see it in all it's nakedness,  intercoolers stayed on the car of course, the twins breath through 3 inch pipes and their oil feed get monitored, as well as the engine pressure by mechanical gauges....it's a Hot Rod kind of thing.

It is still using the stock fuel rails and pressure regulators, so we also monitor the fuel the same way.

We may have to add something to the wish list......

Is it real.. or is it.....

Some time ago, we were commissioned to duplicate a 959.  It started as a one piece fiberglass kit......there was a lot of cutting, but the end result turned out pretty good.

 One mayor issue with these kind of body kits is that it looks ok when it is round, but when you start drawing lines on it, you realized that one side was bigger than the other

Time to divide and conquer..... after getting all the lines to actually look like bumpers, we took a good look at a real one, and copy every single detail.
The front bottom of the doors were round off.
The fender lights were recessed.
The gutter was erased.
The two side doors were made operational.
The fuel door on the hood was free handed.
But the grafted 993 headlights instead.

 Once the body was in good shape, we began on the top end of the 3.6 liter.
Custom made plenums.
throttle bodies.
twin turbos, with manual boost controllers and fully adjustable blow off valves.

We used stainless steel tubing for the vacuum hoses because it is neater, and they use less space, we bent and flared each one of them.

All the fuel and oil hoses were also tailor made with Kevlar lined hose.

Custom headers, pipes and muffler gives it a protesting voice when the traffic is it wants to go.

It is still going through some adjustments, but it has roamed the L A freeways, and so far every one who's seen it believe it is the real thing.
