@Andyrew - Thanks Andrew. I just wanted to be all warmed up on stamping dies for when you bring back your fire wall piece we made on your last visit... (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/biggrin.gif)

On to some boring but very important stuff: mounting the front air dam. Here's a pic to remind you just how awesome this one is. A nice wide opening that's just right for a water cooled set up. It seems this model is no longer available so I want to do all I can to ensure it's securely mounted and doesn't fail like so many fiberglass part do.

And what I mean by "fail" is that fiberglass doesn't stand up well to fasteners. It tends to delaminate, crack and otherwise come apart at or near the fastener locations.
Anyway, you can see this air dam has mounting tabs; the two that you can see in that earlier pic and two close to the ends. It's tempting to simply drill holes in them and bolt it to the car. But it'll be way better to add something that both prevents crushing the composite and better distributes the fastening load: a suitably sized shouldered spacer.

Drill a hole, scuff the area around the hole and bond the spacer to the air dam. Once things are cured, I'll dress the back side of the spacer so it's coincidental with the back side of the tab.

Now when the air dam is bolted on, the entire load is placed on the washer and the fiberglass is just along for the ride. Repeated installation/removal is essentially no risk.
Mo' betta'.

Looks so good.

I wonder if this is one worth re-popping before final finish? Having had one (and I wonder if it was this one!), I'd love to have another shot at one. I remember letting it go because I would have had to butcher it to make it work on a narrow body car. It is maybe the best spoiler I've seen for a 914 short of the factory GT valance and LE spoiler…and I might like it better than either of them. And it might be nice if you had a spare… (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/biggrin.gif)

The transmission is back from CMS. Wow... It's like new.
- a complete rebuild
- newly plated hardware
And better than that, it may be the ultimate G86-20 for use in a V8 914. It's now equipped with:
- WaveTrack limited slip differential
- cryo treated 3.0 ratio ring & pinion (stock is 3.44)
- CMS billet side plate
- CMS shift arrestor (preemptive move to combat the "slips out of 2nd" issue)
- tapped for in/out cooler lines
- tapped for a coolant temp sensor

Apparently I have not logged in for a while, had 3 pages of updates to drool over.
Really starts to look put together when paint/powder is starting to show up.
Bravo

That's what she said! (IMG:style_emoticons/default/av-943.gif)

@Cairo94507 Sorry, that was too obvious a reply, I know. But no, it just arrived yesterday and I have to get a few more things organized. Hopefully in the next couple days.
I also took a huge risk and sent a bunch more stuff off to powder coat. They said they could have it back to me in time for WCR... I feel like the Red Barn is the latest hot rod TV show with all the deadline drama I've created for myself!
Fingers crossed it'll all come together in time.

Let's get this contraption stuffed back in the car! (IMG:style_emoticons/default/aktion035.gif)
The question is: Will I have it ready and all proven out in time for WCR? (IMG:style_emoticons/default/wacko.gif)
This round of updates included:
- all the above mentioned transmission changes
- updated clutch master cylinder (smaller bore to lessen the pedal force)
- minor wiring updates
- some fun style points updates

Those who know me know I have this thing for "style points". These sometimes coincide with my fondness for "matchy-match". I got a double whammy today with some drilled/countersunk holes in the shift lever. Style points, for sure, but also matchy-match with the seat grommets and the window winders - and maybe even the top area of the shift knob.

Closer... and boy, what a difference with the painted engine bay, shiny new trans and some powder coated bits.

All back together enough to complete the an initial, short test run. Note that I'm still waiting for a batch of parts to come back from powder coat, hence no engine lid or trunk. Observations from the first few miles:

- new ring & pinon makes a HUGE difference. At one point, I went to shift from 6th to 5th (based on previous feel of speed and engine sound) only to realize, I was already in 5th! It just lopes along and is far more relaxed at cruise - exactly as I hoped it would. (IMG:style_emoticons/default/smilie_pokal.gif)

- it shifts like butta'. Way lighter movement/engagement.

- the reverse detent is REALLY light. Like too light. Like when you move the shift lever to put it in 1st, you have to pay attention that you don't move past the detent.
I'll call CMS tomorrow and see if there's something I can do about it.

- smaller clutch master resulted in, as expected, a much lighter pedal. But it engages RIGHT off the floor. I'm going to give it another round of bleeding and play with the pedal adjustments.

- I want to get a few more test runs in before I "test" the LSD! (IMG:style_emoticons/default/w00t.gif)

Long story short: For the first time since I've been on 914 World, I'll have a 914 at WRC!
