Turbo RSR project

[NaplesBound]

Tad, amazing as always man. I just got my doors in the other day and now on to the front half of the cage (don't want to cut up $$$ doors) and then on to the air jack system.

I really want to see you car in person man. I vote you finish it, then drive it to next years 12h of Sebring. This way you can stop at my house and I can see it.

Take care brother

Alot of fabwork to still be done as well as welding on the lines from the intake to the intercooler and out to the turbo and so forth...... maybe this kit will do it .......



With all the fluid lines yet to run decided to start with the fuel stuff first. Pump is mounted , going to work my way laying out the lines from the rear.



Need to drill for some bulkhead fittings. Running the fuel lines just to the side of the center tunnel passengers side. Will post some more when I get finished with fuel lines and get the oil lines layed out.

Hey Tad, thanks for the PM and all your advice. What fuel pump are you using? Keep the pics coming!

[tadman]

Fuel pump is a Weldon pump 2015A

February marked my fifth year on this project and the list is getting alot shorter finally. Got all the water lines run for the intercooler and radiator, tank and pump. Need to run it and test for leaks.



Need to make raised cover with duct lines going to the naca ducts in the quarter windows.

Main Item Remaining:
Transmission: Hookup cv joints, clutch cable,omega spring, shifter linkage.

Engine: Fabricating the piping from engine to intercooler and turbo

Wiring: Using the ISIS intelligent multiplex system, solid state, less weight and wire, can do away with multiple relays and its very adaptable. Install time is shorter and much cleaner after the fact.

Over the last couple of years it was always the goal to get the car running by summer. Obviously I did not accomplish that but it kept me plugging along and this summer definitely seems like it might really be possible.

Decided to weld up a different bracket for my center oilcooler. Did no have good access to the oil lines for repairs. Made the bracket where it can fold out, good access for the lines etc..



Bumper and valence remove as one piece for loading on trailer.

Got the ISIS multiplex wiring system today. Deciding on locations for the mastercell and the two powercells. Will post the wiring install when I get further into it.

Mastercell


Front powercell




Rear powercell behind seat

[tadman]

Got started with the electrical system install this last week. The locations did not change much from my first thoughts except for the front cell which I made a bracket and center mounted, easier access.


Rear Powercell

Front Powercell: you can see location for 10 fuses, 5 on each side, same on rear powercell.

Mastercell: The brain of the system, tells the powercells basically what to turn on and off.

8 gang switch panel, switch functions are programmable.

For a race application 8 switches is more that adequate, lightweight and only 4 wires to operate the functions. Small yellow cable from mastercell to switches. The whole ISIS system in the box was only 14lbs.

Megafuses: Megafuses protect the system. The large red wires are the power supply to the powercells.

Megafuse 4 ga wire feed needs to be as short to battery as possible.

Total of six wires on each side. Ten are for items to be powered and a black wire on each side goes to ground. Each items negative wire will go to ground as well. This is not a lot of wires to deal with and once hooked up and loomed should look nice and neat. Will post more after I finish the front wiring and get to rear powercell which will be bulk of work to be done.

Cool stuff. How do you program the ISIS system?

[jetstar911]

Awsome work Tad! keep it coming

[tadman]

To really set up the system the way you want and be able to make changes to the standard system you buy the incode programmer $180. Company website ISIS Intelligent Multiplex System - Automotive Wiring Harnesses, Car Wire Harness, Engine Wiring Harness, Auto Wiring Harness, Truck Wiring Harness, Car Wiring Kits.

[Kroggers]

Thank you for the link. A bit confused, this would not replace the main harness from the DME to the engine as well and the main engine harness will it?

[jharris]

Tad, the car looks great. You're making great progress on getting the cells mounted. This will be a very clean install when it is finished.

We'll get you some suggestions today on wiring your disconnect switch.

Nice fab work and great looking car.

Do you have any details on the red circled area in the pic below? Did you fab that up yourself? How does the ducting work and where is the drain for water? Looking for some type of venting.draining system for my car. Thanks -

If that is the same one as in my car, then it is made by SmartRacing. But not sure if you can still get one from them - Smart Racing Still in Business?

Yeah I have seen that - figured it was pretty overpriced for what you get. I had done some cardboard mock ups of the same things and thought fiberglass would be the easiest/lightest route just have not gotten around to making it yet. His looked to be metal - hence the question. But thanks for the info much appreciated.

[tadman]

Vent encloser is one from smart racing and yes I think they are no longer in business. Krogger you were asking about the DME and the ISIS system. The ISIS system would not replace your DME.

[BB 935]

Hi,

made some sets of copies for my project of a pair of original 934 / 935 reinforcement sheets for he luggage compartment, see pics. Currently in fabrication ist the front aluminium cross and the fiberglass fuel cell pan, pictures will follow.....

Benno

[tadman]

Hi Benno, very nice fabrication. So are you building a 934 or 935 replica or restoring a wrecked 934 or 935 to a replacement tub? Interested to so more of your project. TRE motorsport was making the fiberglass 935 fuel cell cover for the two front fuel cells if you need a source for that part.

[jharris]

Hey Tad,

I wanted to show you the amount of wire that we removed from Jim's 1999 996. We had this in a fish tank at our booth at SEMA last year.

When he installed ISIS in his Porsche, he netted more than 30 pounds of weight reduction in the car.



I'll get more pictures of the car from him when he gets it back.

Jay

[tadman]

Jay, here is the wiring that came out of my car. Have not weighed it but I would not be surprised if its similar weight savings as Jim's 996

[CaptainCalf]

Sweet build!!!

Do you have wheels picked out yet?
