Nice work as always, too bad about the tire issue but looking forward to your results this year on the new setup.

Are your lower seats on upside down?

Cheese and rice...I will have to get those on the right way around. Good thing I have to change them. Boy, good think Greg was around so I didn't get my struts on backwards. End of semester. Doesn't help my ride height.

Yesterday I decided that I should get a lower chassis brace built. Now fully TIG welded and out for coating. Will be installed for this weekends racing fun.

Nice!! I was wondering about lower braces the other day, I would like to say great minds think alike but... :lol:

Here they are on the car.

From the side.

They do make a big difference. I immediately noticed that turn in was much sharper. So that was worth the doing.

So, I've just ordered the wired and fuse holder that I need to redo the faulty fuse holder connector. I thought I was buying the right part when I assembled this thing - weather proof, looks bomb proof and better than the other options and I can attach it where the stock fuse goes. Two years later, I find out it's a Taiwanese knock-off connector and it's not really up to the task. I've ordered the correct parts form Prowireusa.com along with a few other things to fix this once and for all. No more pig tail connectors. For the record it was a Pico connector that I got at the auto parts store that was the issue. The real part - available from ProWire is $6 and is made in the USA.

The car did run flawlessly once repaired - the stress of the last week has wiped me out. Funny how racing does that to me...I want to be out there so bad that it's always a panic if things are not hung together before hand.

Next change will be a set of Kaplhenke Torque Rods. My biggest issue right now is that the rear end lacks grip still. So it handles super flat but it's also slippery. Thinking that maybe dropping the rear end a little would shift some weight back onto the rear end. Wish I had scales to test this out.

We've got scales here. I'm sure we could figure out how to use them...

What rear sway bar are you using?

Thanks Dale - I forgot about those scales. I'm running the smaller stock bar 17 mm I think.

I think I might raise the front 1/2" and lower the rear by 3/4" and see how that feels.

It would be interesting to see what difference no rear bar would make. Not that 17mm is much, but it's something. The comment is always that the thicker the bar, the happier the rear end is to slide.

The bar is most likely a 19. I'll be doing some adjustments and fiddling around over the next few weeks. What is lacking is a systematic approach and data.

Update for the 242. The gauge cluster has been in and out of this car so many times I think I can do it blind folded. So I ordered some custom gauges (S60R style) from SpeedHut. It took them three tries to get the artwork "right" but I'm happy with how they turned out. I also went to New Vintage for an indicator strip. Nothing custom - just Off-The-Shelf stuff so some things you can get and some you can't.

This is the how-to...in case you're interested in having a working cluster with GPS speedometer and things that, you know, work.

One of my three clusters had to be sacrificed. First the gauges were broken out...it's one I've been using for parts for years.

Image

Cracked the front bezel off the main body.

Image

That works - if you're careful.

Image

Quick test fit and marked the screw holes.

Image

Marked and ready to cut. Sorry originality police - this one's a gonner.

Image

The little sawsall works a treat for this sort of careful surgery.

Image

I JB Welded some rivnuts (M4 if you're still reading) into the corners.

Image

Then started the gauge assembly. The SpeedHut gauges are actually very easy to wire up - the indicator strip...well, it's a little more of a pain.

Image

Here's the strip installed.

Image

I didn't take any pictures of the wiring...it's just joining wires. Here's the brake down. The oil, parking brake (brake failure), bulb out, are all triggered by grounds. So join the positives on the LED's and put the grounds into their correct circuits. I stripped wire from a spare harness and used the same pin number for the plug (or as close as I could) - this will help any trouble shooting later. I also reused the fuel sender wiring but replaced the temperature sender wiring as the gauge came with a bespoke sender. The stock setting on the fuel gauge is the correct resistance (or close as anyone could care).

The turns, high beam are positive fed -so tie their grounds and look up the pin numbers. The last bit of fun was the alternator circuit. The alternator gets it's excitation (that's what makes is feel like working) from the gauge cluster. This messed me up for a while and Matt had to explain it really slowly :lol: . I had wired it up correctly, but it didn't work.

The positive goes to switched power and the wire in the main cluster connector (it's red) goes to "ground" - it actually just goes to the alternator. So that makes the thing work until it's producing a voltage then the ground is replaced by positive and the light goes out.

The issue is that the LED draws so little current that it's not enough to make this circuit work. So you can either add a resistor (around 30 Ohms would do) or head on down to the parts store and pick up an indicator bulb (this is what I did - no patience and I wasn't going to go to my lab and get a resistor...I'm like that). Wire it in parallel with the LED - it's now a current limiting resistor. It works. You can't see it as it's wired on the inside of the dash. It should last for as long as I'll own this car.

Next up - how do these fancy Deutsch connectors work? Well they're awesome and they are in the DT series. I'm using them in my 122 build, so have a small fortune worth. I already had the solid barrel pin crimp tool (they're not cheap - they are essential). The DT's also can be had with a standard F-crimp style connector (the crimp that holds wire and jacketing). There is no place for solder in automotive wiring. There, I said it.

The barrel style crimp makes doing this installation possible from inside the car. It took me all of 45 minutes from start to testing. You can try to do this with the F-Crimp style, but it's a lot trickier and the crimp tools are bulky by comparison. They're also a little hard to handled when inside a dash.

The solid barrel style crimp with the right tool is a dream. Strip and prepare the wire.

Image

Get the lengths just right. I have a special stripping tool for this job - it's for Tefzel wire, but works on everything. It won't put a single nick in the wires...and the dies are worth a lot more than the tool. I needed it for work - but I bought it for the future. It doesn't look different from the normal tool, but it is formed differently.

Image

Check the fit - adjust length as needed. You're allowed a few thou worth of jacketing outside the crimp and the wire has to be seen in the inspection hole.

Image

Drop the pin in the tool - insert wire. Be amazed.

Image

This is what you're after - wire visible in the inspection hole, Jacketing just outside the pin and a nice firm crimp.

Image

Insert in the back of the connector as per your wiring diagram and once it clicks in place you're done.

Image

I taped up both sides of the harness with the correct harness tape.

Image

Safely mount the GPS antenna in the unused speaker grille and you're ready to rock.

Image

Nice and clean.

Image

Indicator strip comes to life. I did double use the parking brake and brake failure...so if I'm driving and it comes on, that's a brake failure...if I'm parked - you get the logic.

Image

At night.

Image

This all took a few days and a lot of time in the wiring diagram. It all works flawlessly. It also makes no noise while you drive. I'm happy with the result.
