Dig the cutters, and particularly the five- or six-blade idea, but the baddest 914 muffler of all—in both aesthetics and noises—remains the one used to win Le Mans. A lot of the aftermarket sport mufflers out there (including the Dansk 57mm on my car) are close but no cigar when it comes to the detailing...


Looks a lot better fresh and new Pete ! We're reconditioning the LM muffler and finishing it in grey Cerakote including megs and new set of MSDS gt headers (IMG:style_emoticons/default/welder.gif)

The rebuilt throttle bodies will be here next week. That should address the hanging idle issue.
On the "abrupt throttle response at tip in", I found this part from EFI Hardware out of Australia. It has a far more progressive cam profile than the stock one. Fingers crossed that between this and some adjustment at the pedal, I'll have a softer throttle.

I should be back on the road and doing more development by mid next week.

The throttle bodies are back and part way installed. Turns out the new linkage cam will require a different set of throttle cable ends so I've ordered the needed items.
In the meantime, I decided I wanted a version of the access panel that didn't require the carbon inserts. So I cut and pressed a new set of panel pieces.
I took some time to tune up the stamping dies and got a really nice result. Now to weld up the seams...

And there's virtually no way my car will be ready for WCR but attendees are welcome to come by the Red Barn to see it, if that's of any interest. I'm about 3 miles from the Motel. And I have beer... (IMG:style_emoticons/default/beer.gif)

- Throttle bodies factory refreshed with all return spring correctly installed? Check!
- New bell crank/capstan with (hopefully) improved, more progressive off-idle throttle response? Check!
- Updated throttle cable needed to work with the zippidy do-dah capstan? Nope, those parts won't be here until next week...

Well, that doesn't stop me from firing it up. And fire up it does. Same tune as before and notice that with all the return springs in place, it settles right back to idle! (IMG:style_emoticons/default/aktion035.gif)

Given the current tune was set to try and compensate for what neither the tuner nor I understood about the messed up return springs and how that was driving the hanging idle issue, I'm confident this thing will be even more snappy, once it's fully dialed in.

So, there is a WAAAAY outside chance it'll be able to make a very brief appearance at WCR. Fingers crossed!

I should know better than to get near my car when waiting for parts - I seem always to find something to re-do. Going in, I just KNOW it's bound to be an improvement! (IMG:style_emoticons/default/laugh.gif)

Today as I was looking at the access panel I was about to redo for the 3rd time (IMG:style_emoticons/default/huh.gif) , it struck me that instead of welding the panels together, I could rivet them.

That should (?) leave me with a more cohesive look, IMO, given all the other rivet lines in the interior. Remember, the top panel of the console will be riveted on and using rivets on the access cover will carry the look right up to the rivet line at the top of the firewall.

Back to CAD, then cut and stamp new side panels! I extended them enough to be able to radius bend them and end up with a return to which the front panel will be riveted. Forgive my drawn on rivets, I just wanted to get a feel for the look.

I think I'll put a step in the returns so the front panel sits flush vs one panel thickness proud, as in this pic. Still some trimming and fitting to do, but you get the idea.

You could just leave cletco's on there as well (IMG:style_emoticons/default/smile.gif)

I used the bead roller to add the step then notched the corners so the center panel ends up in the proper plane. The second pic show sorta how the panels come together.

Once I step and notch the other side, I need to narrow up the center panel to fit. Ideally, it'll still look OK in terms of the width from the outside edge to where the stamped recess starts.

If not, I'll need to remake the center panel stamping dies and make a new center panel that accounts for the amount trimmed off... But I think I do like this look.

With the center panel trimmed to fit, it was time to be sure @Andyrew was granted his request! ClecoBoy is back. (IMG:style_emoticons/default/shades.gif)

It's good to have options. (IMG:style_emoticons/default/laugh.gif)

- The one on the left is a pure temporary that I can run while doing all the "get it running and driving" stuff. It'll never be worked to any higher finish.

- The middle one will be finished, painted and have the carbon inserts bonded into the openings. This will be the "fancy" one.

- The one on the right? I'll use panel bond, same as I did on the other fire wall panels. It'll then be painted and get the same structural rivets as the rest of the fire wall.

Now what can I re-do? (IMG:style_emoticons/default/happy11.gif)
