I've heard its a really nice car, I know one of the mechanics at Merlin and I reached out when I saw it  landed there last year?  I was kind of hoping it was a different car though because now I have no idea where the 3rd 365 converted car might be, I hoped it was yours and I could stop wondering.

I posted this a few months back but in case you missed it, conversion #1 the goldsmith car that moved to Germany a few years back is for sale at 475keuro...which seems like a very strong ask but what do I know

Goldsmith V12 308

 

Can't wait for the drive video!  stay safe, I read Milton is a cat 5 storm now  surprise

Hopefully my engine is sorted now and I can make one of my own soon and see if it really will go to 11 devil

The new A-arm bolts came so I welded them into the brackets and...or there was a reason ferrari used a very thin head...to the mill with them

With that fixed back to the car...the a-arm bushing area is larger than the bracket and now hits the frame

so I moved the frame and it installed nicely

the a-arm has a nice angle to it now

and there is an extra 15mm of thread which will add about 2.5deg range to the caster adjustment and let me get to at least 3.5 and I can't imagine wanting more than that.

This all took much longer than planned so I only got the 1 side done but now I know what to do so the other side should go pretty quick.

The last few days I've been talking cars with the injector guy and he mentioned getting the traction control working and really liking having so i was feeling left out since my ECU is not reading the speedo sending unit like I hoped. I hooked the scope to the wires at the ECU, jacked up the rear, put it in 5th and cranking it over.....hmmmmmm....not at all what I expected nor anything I've ever seen, a 4-9V square wave signal coming from a 2 wire sensor.  I saw the 2 wires and assumed it was a reluctor but it obviously is not.  I might be able to read it on a digital input.....if not I'll need a new plan.

I finished side 2 and it went pretty easy and the injectors arrived so I'll get going on the intake tomorrow.

Today at work I was chatting with a guy trying to get his project together and running and he was asking for info about the haltech he's installing and the plug and play pigtail he'd bought and that how to repurpose some wring and such.  As part of that I went through the 5V sensor supply and the sensor grounds and that sensor ground is NOT chassis ground and mixing them will cause problems and that got into a talk about good grounding and why there are so many small grounds everywhere cars once ECUs were added and how before that everything used chassis ground so most old sensors are just 1 wire because they ground to the engine but you never see that today because it pulls coil or alternator or whatever noise onto the signal lines and they were mostly analog so they wanted as much signal as they could get reliably and 8V became a standard so ECUs that have been around a awhile like motec and haltech have both 5V and 8V sensor power outputs.....wait old sensors don't have ground wires......yup, the 308QV speedo is a has a hall sensor with an 8V supply and grounds through the casing so only 2 wires.  For whatever reason it only pulls down to about 1V not 0V but I think that will be ok on a digital input to the ECU.  I'll try it tomorrow.

While getting ready to test Lana stopped out to...ummm... discuss a couple things with me so I was a little distracted and didn't remember that I had moved the jack from holding the rear tires off the ground to position the A-arm at ride height when I tightened the a-arm bushings.....so I engaged the starter with the car in  gear and dropped the front off the stands.  Luckily one front wheel was still on and the only damage was to the jack stands....I guess its good they were cheap and just bent....

It was a take a minute and collect my thoughts moment for sure.

But it is an opportunity for get some nicer jack stands. The now broken ones were pretty cheap and the other set I have is cheaper and honestly kind of scary.

I ordered 2 sets of these. They have removable pas and actual feet so its safe on pavement.

Years ago I gave away a boat about 6 times and yet it remained in my yard so I listed it for sale and it was gone in a couple hours.  Can't give away dyno rollers? sell them!

 

This evening I should have been working on the intake but messed with the rear wheel sensor instead....ECU still won't read it.  I'm pretty sure its because it doesn't actually go to 0V.  I am NOT in any way an electronic guy so in my mind all I need to do it put a 5V zener diode in series with the 1-7V signal and the ecu will see a 0/5V signal and be happy....I think I'm going to try it.

A 1k pulldown from signal to gnd would be what I'd try first.

That was my first thought as well (with a 10k).....but that signal is not going to ground and I'm pretty sure that is on purpose, because 1980s, and I don't want to take out the the speedo.  My second thought was a couple diodes in series, figuring each will drop about 0.7V and 1.1V will follow nothing....but then I though might as well use a zener.  This morning I was at a 5V zener plus a 10k or 100k pull down and it seems like has to work and the speedo shouldn't even know I've touched it, at least has to work one of the 2 digital in channels with no 10k 12V pull up that the other 4 have.  I have the 2 front wheel sensors on the 2 no pull-up channel because they don't need a pullup and I thought the ones with the pullup were more useful in general, so I need to move 1 while I wait for the diode kit that's coming Wednesday because I couldn't find any here and just running to radioshack is no more.

Today I re-pinned the ECU to get the speedo sensor on the input that I think will read it once the bits I ordered arrive, just so its ready

Next one bolt didn't feel right last manifold install.  the bolts I meant to use are 20mm but for whatever reason I have a bag of 18mm long bolts and as I dropped and otherwise lost the 20mm long bolt a few got replaced and the one the felt wrong was 18mm lg....so all the 18mm lg bolt went in the trash and the sketchy hole got a helicoil.  I couldn't drill or tap straight to save my life so I made a drill/tap block like always.

When I opened the injectors they looked new, clean everywhere, new o-rings and on top an o-ring spacer replacing the double o-rings I had been using.  I feel like another shout-out to mitch at T1 Race Development (where the service request or injector dynamic went), he did a great job.  

When I was pulling it apart I popped the plug off injector #7 but could remember needing to release the latch....yup, it was broken.  Lucking for a reason I do not real  have a handful of spare connectors so i could replace itr without causing any delays 

then, because I'm me, I put all the injectors in flow order with the lowest in #1 and highest in #12.  My thought is that now with a TB bank adjustment I can match the air flow to the injector flow....at least in my head. With that done, intake on

Tomorrow early i need to make another trip to tirerack for the Supra's winter tires then the manifold sealer should be hard so I'll pressure test the fuel system and get the last few bits on then hopefully make some noise after lunch.

The fuel system leak test leaked fuel so that was sad.  I removed the intake and it was clear several injectors were leaking at the fuel rail but it wasn't clear why.  After stewing a bit I removed the new correct o-rings and fancy spacers and switched back to the double slightly smaller than correct o-rings I'd been used, polished up the o-ring bores a little and put it back together, no leaks.  So tomorrow will be make noise day I guess.

I'm honestly coming to dread noise day because it usually means I'm getting sad news of some sort.  A buddy from work is trying to talk me into an autocross at the end of the month and is willing to trailer the car  there for me.....but I have ZERO confidence I could get it started on command and then keep it running for 45 secs 2 weeks from now.  Next year maybe.

33%more than 12 as in 16 cylinders?  Or 33% more than it started with so ,....6 to 8?  

Edit...ahh, found it, I'll have a look!

Today was to be a couple firsts, it didn't work out...which is why after like 8 year of failures I've come to dead run days.  The plan was to run it with the air box on which also means starting without ether.  I figured I had 2-3 hours before  I wanted to make noise anyway and it it now runs decent it would be nice to maybe drive and not worry about gravel in the the intake.  

Step 1, the air box.  When I fitted it last time I just removed the fuel return hose with a plan to relocate it at a future date....which was today.  I found a fitting that would work but in the wrong color so "for now" I used it anyway,  spray painted it the right color and setup the the hot air gun to speed up the drying.


Step 2, filter boxes installed.  I never really had a plan on how to secure them so "for now" they got glued and some duck tape to hold them while it dries

Step 3 the air air ducts.  The Passenger side went right on, pleasant surprise.  The driver's side I decided I had been a bit too optimistic in my ability to tuck wiring out of the way so I my some additional clearance and closed the hole with duck tape "for now"

Not bad!

The tires are probably too close, I'll need to seal with that but it looks ok "for now".

Time to make noise.....why isn't it starting?  Ok, a little ether in the airbox and just a couple pops???....and why is the MAP reading 16kPa when it should be close to 100???....because its broken again.  There was no voltage on the10V buss so I ordered a pack of 5 power supplies for $6 delivered tomorrow to use "for now".  

But something made me dig a bit more.....and there was no 5V on the 5V buss and I was seeing about 138Ohm to ground when it should be a couple kohms.  I removed the old 10V power supply I was replacing and the output conditioning stuff that never worked right so I don't use...no change.  The sensors are the only other things on the buss so I clipped the sensor 5V pins one by one, no change so I guess the corrosion in the board that killed the 5V to sensor 7 has spread.  I made a new 5V buss with jumper wires "for now" and the board is working again other than the 10V power supply coming tomorrow.

So tomorrow will be get the MAP working on the bench with new bits and then onto the car and it will likely be dark so next run attempt will tentatively be  Tuesday.  If the MAP goes quickly I may add the hood Monday night so it looks like a car that should drive.

The power supply thing said it was coming late so I decided to just get on fixing the air ducts so they don't get broken...and as soon as I cut a chunk out of 1  the amazon guy came....but I was committed at that point.  I reached in and marked the best I could then cut out a chunk.  I picked up some 5 minute drywall mud and kind of coated and inch or so inside the cut-out, then made a pile on a plastic bag and puled the duct onto it and let it dry....no more hole

It may say 5 minutes and it does set up, but inside was still soft an hour later when I started shaping it

Then I dropped the suspension as low as it goes, about an inch below normal and worked the duct until a 1.5" spacer fit with room to spare so maybe 2" more travel or 3 total.

Then glass it up.

Side 2, the one that I already cut for the wires/filler neck got a second cut for the tire and both sided filled with mud.  I did the first test fit and I still have some cutting to do and it was late so tomorrow job.  Once I'm happy I'll power wash the mud out since that worked pretty well last time. 

I did put the power supply on the bench and confirmed I could set it to the correct voltage but didn't wire it to the MAP...another tomorrow job once the glass is curing.
