The LS packaging is pretty good, 430 lbs is pretty light for something that can make 450-500 hp pretty easily, and have that power all the time

See if you can get OEM S550 mustang calipers to work, I think that those are pretty large

There is a company from portugal I think that makes a cheap sequential, a lot of rally cars use them, I saw one in South America once in these tiny little track cars, I will let you know if I come up with the company name

So many wires. How did you get to 120? I'm at 60 or so. VVT and o2's?

I found the below that can be bulkhead mounted. Only sealed behind the pin. Multi sized pins up to 4x40amp pins.

Those work pretty good, I was thinking about getting some, but they can be hard to actuate if they get dirty, we actually sell a boot to protect the slide from dust

Regarding potting components:

The only components being potted that are serviceable easily on the side of the road are ones that aren't critical anyway.  It's a massive process to get to the cam/crank sensor plugs (mostly crank and the "lead" cam that the engines uses for readability;  driver side is easier, but I can unplug those and the engine will run, just no VVTI).   If I decided to do Drag Week or something, I'd just buy another one and pre-pot it as a spare.   They don't have a lot of these at AutoZone anyway.   The DBW throttle body might be the one exception, but again I can get a spare control board for one pretty easy and prep it as a ready-to-go spare or rig up an adapter plug if I had to.

Planning all gold contacts, the total cost difference for gold vs. nickel is maybe 30 dollars for the whole harness, it's minor in the big picture anyway.   They'll all be solid, I have DMC crimpers in the right sizes now.  I had been using stamped and the proper solids are just so much nicer overall, so I'll probably replace the stamped ones on the interior with solids also.

I have mil spec connectors on the firewall already.   They're just Amphenol nickel plated pieces, nothing ultra fancy.    The harness will just run where it lays nicely and is servicable.  I care way more about efficient layout and easy of maintenance than I do about it looking fancy.   Form will be a result of function, not the other way around.  :)

Nice!  Gold is worth the difference in price.  I am looking forward to your progress.

Nice work!  I saw the intake on FB, looks so cool

Blake this is awesome that you are taking the plunge.  I would recommend getting gold plated contacts for the signal wires if possible.  Are you using the solid or stamped and formed contacts?  what are you doing for the bulkhead connectors?  An HD30 or HDP20 would probably work well.  I would also go ahead make lengths so you can tuck it all, I think that would really make the engine bay stand out when you pop the hood.

Look at Ampseal 16 connectors as well, they actually perform better than Deutsch, but are a little larger.  TE makes both of them.

Those look nice for in the car, I might have to snag some!    For under the hood, I can't find any connector bodies that I can seal with heat shrink/adhesive.

That is true, they went with plastic boots which donít look too Motorsport.  Most OEM just rely on the seal in the back of the connector to seal and it works fine, but nothing looks better than a hand lay harness encased in DR25 and raychem shrink boots

We don't actively act on it (in closed loop I mean), but we measure all of that on the drag bike.

OT, but congrats on this!

Thanks!   It's pretty amazing!

Been waiting to comment on this since I started reading this thread (3 days ago) lots of awesome info Blake!

Thanks!

I'm working on the wiring harness design.    I'm planning to go pretty stupid on this;   doing all concentric lay Tefzel under the hood (probably for the engine wiring under the dash also), DR25, potting all the custom Ford sensors and converting to Deutsch DT connectors, Raychem DR25, etc.    It'll cost a bit, but it should future proof it all.   The setup I have now is "fine" but it's too tight and the lack of concentric twisting means that it isn't flexible enough.   I also branched things in ways I don't like now that I look at it in retrospect.

The new harness will have subharnesses for various aspects, I plan to run main trunks from each bulkhead (just like now) but the parts on the back of the engine will be picked up from UNDER the intake manifold, so the main branches will run forward, then drop under the intake to get to those, where they will be connected to subharnesses.   I'm also going to use fully shielded cables for all VR/Hall effect/knock/CANbus stuff, which should eliminate 100% of possible noise issues (I don't -think- I have any now, but I'd rather be 100% sure).

For those curious, I'm expecting around 1600 dollars for the harness components.    I think the grand total to replicate a similar setup with the ECU, wideband CAN controllers, CAN expansion box and the entire harness will be around 5,500 dollars (sometimes I wish I didn't track this stuff).

Look at Ampseal 16 connectors as well, they actually perform better than Deutsch, but are a little larger.  TE makes both of them.

LS swaps are everywhere because they are such a reliable motor.  I would personally like to see an Ecoboost swap, or maybe a BMW N55 swap?

Not to derail but there seems to be three types of systems.  Your route where its a ECU and you configure and tune everything (seems to be hardest??). 

Then there is the MSD Atomic, FiTech, etc that seem to be dumbed down?  Thoughts on those (the dumb ones LOL)

Then a 3rd category of using a HPtuners/EFI live and OEM computer, I seem to prefer this but I don't know why. 

Also why no Motec?  Too much money?  I have one on my turbo charged 300hp snowmobile, its actually seems more clunky then HPtuners on my 'dumb' LS1 ECM. 

I truly don't understand which one is mo betta?  There has to be a best right?

Motec is by far the oldest, most established, and in professional sense the best.  You can buy one ECU and it can run anything from your snowmobile, to an LS, to a Ferrari V12.  It is clunky feeling because it has older GUI

I believe an OEM computer that can be tuned is the best option.  Standalone ECUs are best when you are building a race car, or if HP tuners does not provide everything you want it to do.

I think you could easily sell for 25k, Maybe list for 30 or 35?  I feel like there has to someone out there that wants a crazy high HP car.  How driveable/reliable is it?

Nice write up Blake.  This might be a good YouTube video!
