Rick/Rob... I'm using your method of dealing with the power-steering/alternator drive belt space problem.

I have built the power-steering pulley spacer 320mm. This lines up the forward-most groove with the forward-most groove of the alternator.

The power-steering pulley has 5 grooves, while the alternator pulley has 6 grooves. What belt did you use?

Also.... what idler pulley did you use on the alternator pivot bolt?

Thanks!


Getting dangerously close!!

BrianG

Got the pulleys and idlers sorted!

Last few items and we're ready to light it up... hopefully today.

One wire left without a place to go........ it arises from the lower left, front side of the engine harness. It separates from the large harness together with the coolant temp sensor lead that sits in the coolant bridge. It is substantially longer than the coolant temp lead and look to be the lead that would travel to the top/front of the original intake manifold to a sensor that is still there in the manifold.

My question: Is that sensor to be transplanted to another location in the SuperModel installation?

It has the circular sensor attached to it - correct? Does your bypass piping have a nut welded in? You should be able to screw it into that nut. It is also possible that you have a nut on the driver's side of the manifold to screw it into.

This should be the air temp sensor that screws into the top of the original manifold. Andy basically stuck it on the top of the manifold tie-wrapped to a stud. Ideally it would be installed into the manifold. Mine has been like Andy installed it 18 month ago.

BTW, unplug the vapor recovery valve switch that resides in front of the motor.

BrianG

No nut on the by-pass pipe, and no nut on the manifold.

There are a couple of bolt-ends protruding up through the top surface of the intake manifold, from somewhere underneath. There are 2-3 threads visible so I think I can weld a plate to the bottom of a nut, drill and thread the plate to the specs of the protruding bolt. Might this suffice?

Is this the wire that travels forward with the left side fuel injector harness and the front knock sensor lead?

Last week I had a high speed run and the P/S belt hit the radiator hose and caused it to leak. When I got the car the belt was close the p/s pump and was about 1/2 from the hose (btw, p/s pump has 1-1.5mm play).

I just put everything back together and took the car for a spin. I drove about 3 miles and the belt skipped again toward the hose and it slightly touching the hose.

Better yet, is there a source of p/s pulley with a wall?

Bill, can you tell me more about the spacer you made? Btw, the hose is strapped at the radiator shroud. The p/s pulley has 5 groves and the belt has 4, should I get a 5 groove belt to fix the problem?

Thank you kindly

Gio:

As I mentioned before a pre-85 radiator hose would alleviate the PS belt to hose interference.

The misalignment of the PS pulley that causes the belt to move forward requires a spacer behind the pulley. I will have to take the pulley off to take some pics, but it is a simple design to move the pulley forward with a center boss to keep the pulley centered. Any machine shop should be able to make one. Something like 5 mm should work. A 5 rib belt won't help it stay on and will use up a rib on the crank pulley that you need to keep the belt separated.

On my 89 it is over by the right side fuel rail. Here's a pic. It's behind the upside down oil dipstick an plug wires.

Giovanni

Ok, I will get the spacer made and install the '84 lower radiator hose.

BrianG

Got some more loose ends looked after, but still a few left to go.

Thanks to Bill for the throttle cable ideas.

Thanks to Rick for the accessory belt rationalization.

Thanks to Mike for all the handy tid bits along the way.

Man.... there's a lot of RED in there!

Is the '84 the same as the other hoses? I always order an 85/86 hose. I think its the one you want.

mspiegle

Good luck! Sounds like you're almost there

Bill Ball

See the PNs below from the PET. I ordered the PN ending in 06 below. I didn't notice that 07 was an option. It looks like 07 (on the 86) is interchangeable.

78-85 - 928 106 239 06 or 928 106 239 07 [EDIT: superceded by 928 106 239 08]
86 - 928 106 239 07 [EDIT: superceded by 928 106 239 09]
87-95 - 928 106 239 09

Btw, Horsepower TV (on Spike Channel) has an interesting eposide on Superchargers right now

"Is the '84 the same as the other hoses? I always order an 85/86 hose. I think its the one you want."

The fan schroud on the 89 stand out 5 1/2" while the 84 schroud stands out only 2". After looking at both cars I do not see how I will benefit by installing the stock older radiator hose. The schroud itself is close to the pulley.

Bill, do you have an aftermarker fan setup?

Thanks
