My city is in lock down again. So I have some spare time.
After taking the SC off for an engine rebuild a few years back - I think its time to reinstall the SC and enjoy it.
Time to gather parts and check and clean things before beginning the install.
Enjoy the pics.

Some parts out for powder coating:

 

SC inspection shows the teflon coating is coming off the rotors.
Time for disassembly and service of the entire unit.
Oil change and bearing checks, etc.

 

Took some time to de-grease and fully clean out all the parts.
Teflon removed from rotors. Shiny !

 

Minor scoring on rotor edges and case after careful inspection.
As expected with little use of the unit.
Bearings are good - zero play.
Snout section is good.
Time to reassemble.
Old oil not a terrible color. Will replace with a GL5 rated gear oil.

 

Cool project - thanks for sharing!

Nice! Are you going to plumb an intercooler on it?

 

Yes - we will focus a bit more on heat management with this reinstall and try to reduce some heat soak.

A special mount has been fabricated for the charge cooler and we are just confirming sizes and mounting points for the heat exchanges.
Right now it looks like we will use a CSF #8066 to provide good cooling for the charge air.
We will reuse the larger Bosch water pump from before.
Alternative will be to modify the bracket and mount where the AC heat exchange is.

We will add additional transmission cooling - mocal thermostat and possible another CSF #8119.
Deciding this week and will order shortly.

No meth injection this time but ports have been built in if we decide to change our mind.
We will keep boost at 6psi and will not venture to 17psi like last time.
A little more power and longevity is the goal.

 

Carbon intake pipe arrive the other day as well.

 

Just doing a mock fit and checking things.
This is the last setup we had before removing the kit.
I think we will want a much larger water reservoir so we can get more cold water at any one moment to cool the charge air.
Will need to look at what off the shelf options are available.
We may try some 3d printing (and take a page out of the book from Jonte's amazing project) to create a heat shroud / better air intake for the cone filter in the stock TPC configuration.
If anyone has any thoughts let me know.

 

You have some very nice fabrication going on there!!! Keep up the good work!!!

I have what might be an earlier TPC Supercharger on my 1996 993. No inter-cooler but TPC did a dyno/tune at there shop almost twenty years ago shortly after the install. The 'best bang for the buck' IMHO.

I was made aware of some SC belt misalignment. I ended milling the SC mounting holes and placing a spacer nut at the front screw/bracket mount to get the belt to line up properly. The TPC manifold and connector boots influence the location/angle of the manifold that sets the pulley alignment. Just something you might want to look at. I have no belt noise.

A few years ago, I asked Tom at TPC about the Teflon flaking and he said 'don't worry about it'. Are you looking to have the rotors re-coated with new Teflon?

Enjoy that Puppy

 

Sorry for the late reply Mr Bock. I have many pics of your car. Lovely car you have.
You are 100% correct with the TPC pulley setup.
In my last setup I had very slight angle of the pulley towards the engine fan.
But nothing major that was a show stopper. Things worked perfectly fine.
I will be adding a very thin washer to compensate this time around. Thanks for the advice.

I will not re-coat the rotors in Teflon. I am told it will eventually flake again and I'm not keep on getting Teflon particles in the charge cooler or engine block.

Many parts arrived over the last week so I can probably start install this week. Happy days.
Still waiting for some hoses and fittings.

The CSF rads are impressive. Very well built. This one I have feels like a brick.
The turbo injectors are super expensive. sigh.

 

Had a couple hours before I had to start making dinner.
Might as well get on with this install while waiting for other parts to arrive.
Stock 3.8psi FPR out and 4.5psi FPR installed.
Fuel injectors installed.
Feeling a little high after sniffing petrol fumes.
Need to get some more gasket maker for the throttle body install.
Man I love this carbon fiber pipe. Half the weigh of the stock metal one.
Not that a few grams matter anymore when the SC components are going to add 20kg to the total weight.
Also can't see it since its right at the back. But lets hoping it adds some cooling.
Tomorrow I think we will do the throttle cable support, take apart the alternator and fan and mount the new fan pulley.
Then we can drop the engine and mount the lower pulley.
Till tomorrow - and I think the other parts just arrived as the post man just rocked up.
Yay !

 

Not much progress today.
Forgot how much I loved taking the engine fan out and pulling things out and pressing things on - NOT.
Anyway - ran into a problem. I don't remember having this the 1st time round.
But I needed to add two washers to get an addition 6mm to create a gap between the back of the TPC style fan bearing and the face of the alternator.
When no washer is in place I can push the fan back a little more and the opening of the fan bearing piece will rub with the alternator housing.
Very frustrating having to take off the fan 3 or 4 times to figure things out and get measurements done and the right size washers.

If I measure the stock RS pulley bearing piece it does create a 12mm gap and the TPC unit only a 5mm gap. Funny - I don't recall having this problem when I installed the unit the last time.
Anyway - engine fan portion is done. We shall drop the engine in the next episode.

 

Hi wondering why you replaced all fuel injectors. what kind did you get?
nice work
