In keeping with the full disclosure approach: Good thing I video'd the ITB operation.
I thought I'd avoided any interference with the linkage but it turns out there was some!

My zippidy do-da MAT sensor mount fouled the linkage as it approached WOT. Heaven forbid not being able to achieve WOT in this thing...
Anyway, it's nothing a bit of trimming couldn't resolve.

First pic is closed throttle, second is WOT. What's interesting is that the linkage geometry is such that that the last bit of pedal travel moves the linkage arm WAY farther inboard. Anyway, problem solved.

I love it when you can fix problems with a grinder smile.gif

I realized I'd probably want the engine inspection cover to be in place ahead of getting it running. As with the radiator shroud, the final version of the cover will need painting before I bond in the carbon panels.
So I dug out V1 of the cover, cut some suitably shaped steel panels, placed them in from the back side and spot welded them in place. From a distance, they almost look like the stamped pieces.
Not the most attractive, but I now have a serviceable and reasonably fire proof fire wall.


not to be overlooked, those seats are great, what brand?do they mount on stock seat sliders?

@DRPHIL914 - They are GT Classics, LeMans model. Specially for the 914 and yes, they bolt right to the stock brackets. I added heat, the grommets and their "oval" headrests.

Well, @bbrock , it Depends... lol-2.gif

And for those who may care, @markhoward and @buddyV are coming to the Red Barn tomorrow at 4:00 PM to man the fire extinguishers while I attempt the first start!
My lovely wife will handle video duties to capture the moment for posterity.
Wish me luck!
Cairo94507
Darn. I was hoping to be able to be there when it breathed its first breath in the car. Well I know you will document it and post the video.

It will start on the first crank and run like it has been running in the car forever. But the fire extinguisher is handy and smart as well as making sure you roll it out into the driveway before firing it. That way the neighbors can appreciate it better. popcorn[1].gif beerchug.gif

Do Mark and Robert know how to use a fire extinguisher? Just remember PASS - Pull, Aim, Squeeze, Sweep (at the base of the fire)! lol-2.gif Probably nobody would notice a bit of extra smoke in the air.... Wish I could be there to see this moment, but I'm looking forward to the video cheer.gif

agree.gif BTDT, watched the mushroom cloud drift towards the ceiling. Fast blip of the throttle took car of the fire, but still made my wife's eyes go really big.

Roll the car out. Once it fires give you a good reason to slap some old rubber on it, and do an epic set of 11s.

This car does have an LSD right? A smokey 1 is not cool. Oh hell, even if it does not start it is still cool as hell. Enjoy. popcorn[1].gif

Come on man, it should be your tricked out on board fire suppression system that handles any contingencies! Knowing your engineering it would quench all the wild fires in the region too.
Nogoodwithusernames
Looking forward to a video tonight! Good luck!
Curbandgutter
Amazing! You must be on cloud nine man. I can't wait to hear it and see a drive.
tygaboy
OK, here we go. I said I would document the whole thing so this is ~56 seconds of your life you'll never get back but it's f-ing excitingly nerve-wracking for me!

Yes. it's just a video of me putting gas in the tank. I won't be hurt if you skip it! happy11.gif

This is the first time my car has had fuel in it since I've owned it. Remember, I did a bunch of welding on this tank so I figured I'd be sure it was good to go in time to let @markhoward and @buddyv know if there was any change of plans.
No leaks!

Onward!

Hook up the battery, ECU NOT PLUGGED IN.
I just wanted to verify that what was working before was still working. But at the end, I couldn't resist verification that it would crank over.
Again, this is the first time power has been put to many areas of the harness I assembled.
Did I say I was nervous?

So far, so good. Now, it's wait for the crew to get here to see if she'll start. Fingers crossed!

@djway - good catch. I was thinking maybe I should wait for the next track!

Having never done this stuff before, I had no idea what to expect so be nice if you've done all this. I happily admit I'm a newb...
My comment "...this is brand new technology" was supposed to end with "to me."

But it seemed we were making progress.

Seemed to us it might not have been getting fuel. At Mark's suggestion I disconnected the ECU and the fuel pump, cracked the Return line connection at the fuel pump, put 12 v to the pump and let it run until it weeped fuel at the Return.
Then it was tighten the Return connection and run the pump for maybe 30 more seconds to see if that would fully prime the system.

Here's what that did for us:

So there it is! The beast runs. aktion035.gif

The amazing thing to me is that the stuff I did for the first time, like making the main harness, customizing every terminal/connection on the engine and ECU harness and making all the fuel lines, all worked!

A few things left to tidy up but it's on to the next goal:

Maiden voyage on 9/14!

Huge thanks to Mark and Robert for being there to help and support me today.
@markhoward @buddyv - Guys, I couldn't have done it without you. pray.gif Thanks.

Well, you called THAT perfectly! Robert @buddyv proves just how far beyond thoughtful he is with the uber cool, custom made, memorial T-shirt he broke out after the the successful start. It goes great with my Covid hair-do, don't you think? lol-2.gif

But seriously, a guy couldn't ask for a better pal! smilie_pokal.gif beerchug.gif

Great job.

When you have so much engine and rotational inertia that the torque generated just by reving the engine makes the car body rock . . . you have probably enough engine. happy11.gif

Glad to see this beast running in the light of day!

Great job!!!

Where is the video of all the times you restarted it?
Because we all know you restarted it several times and it got more and more awesome each time. welder.gif
