I don't have any establishing wide shots, because this was not supposed to have turned into a project. But here we are. My 93 RX7 is single turbo with a half bridge. I wanted to move down in size on the exhaust housing.  But that turned into "well that should be worked on, and that should have been done better, why did I do it like this?" Basically 15 years of "GETTT ERR DOONNEE" has amounted to a pile of poo poo in the engine bay. So I'm slowly pulling most of the things out except for the engine.  The plan is Replace AC lines with AN hoses Replace PS lines with AN Replace dual oil passive coolers with one fan cooled cooler Replace OEM fans with slim brushless PWM fans with controller. I think I can get my AEM to drive them if I set the tables up correctly. poo poo can a ton of the stock relays and wiring, wire tuck (kinda). And fix whatever else needs fixing.   Water manifold tapped and plugged.  Gross stock fans on a Koyo:  Me afraid to touch air bag wires:  Body side of ignition harness (im gonna cut you)  The only real truth

Yeah it's not too bad. Plus I work for an engine builder so there's a good discount. There are AC to AN adapters but I'm just going to cut the ends of the existing lines and weld on AN fittings. My system might be "AN compatable" but I'm not sure what that means other than the thread pitch matching.

Small update. I had this powdercoated alternator case I could never get to work, so I went ahead and removed as many powdercoated contact points that I could  Blasting the oil off the coil and charging harness before tearing it down:  Chineseium oil cooler with fan to replace dual setup:     That's it for now.

a sequential setup just sounds like an expensive nightmare that I don't want to deal with. I'm not even running ball bearing because of cost right now. Precision Turbo has pretty scoocum housings that I'm using and my target is just "better than it was." I'm very la dee dah about it all. I just want it to run well and look good.

While waiting for the fans I got a surprise package from Japan. I'll take two packs of smokes and a strut bar please:  The original idea was to replace the stock bar for something raised a bit higher so my sub box could tuck in under it  That was not the final result as all i could go by was photos. Oh well...  You shiny gently caress! I never cared for aftermarket bars, what possible advantage could they have over stock?  I have a small battery, so I thought it would be a good idea to get a capacitor to help smooth out heavy hits to the alternator, BUT I'm only familiar with microfarad units and didn't know how big a real farad was. So I have a cap bigger than my battery, where the gently caress do I put this thing?  Bonus work photo of me about to dig into some of this wiring because the injector drivers need to be re assigned to different injectors. (which, yes, can be done in software but we ran out of room between each cycle at high RPMSS and need physical separation, fakck offff).

This screwdriver was stuck inside for 10 years:  Wiring slightly less of it:  Anodized socket heads don't clear the pulley. poo poo. I'll get back to you later  The fans have arrived:   14" was the smallest in stock for months. So I'm just going to have to make them work:  The pizza box the fans came in work great for a template:

Haha, no the boxes are much taller and bigger than that. I just found it kind of funny Well I hope someone here knows how the inner workings of a brushless fan works. Because these seem to be a bit defective. But first I am not a fabricator:  And I will use the plasma cutter as I see fit:  Yeah these things grind on fireup, but they free spin just fine by hand, which is just having me scratch my head. I use Spal brushless at work all the time, so I know this is not normal behavior.

It almost makes me think it's the way the computer is delivering the power. I've tried it in PWM mode and without. Same results though. I'm letting it run on the bench for an hour at low speed and I'm going to check if it's any better.

Okay I was able to get in touch with the Delta PAG guys. This is normal behavior for this motor. The motor starts on two of the three phases and used the third as a sensor. After startup it uses the three phases. It is the first of its kind from what I can tell, they have patents. So a little annoying but neat I suppose.

IOwnCalculus posted:Are these that much thinner / that much better flow than traditional E-fans? I'd love to pitch the non-clutched mechanical fan in the Opel. They aren't any slimmer. The main difference is the amperage usage. At my work we started to require our customers to use them because of the amperage limit of the Motec solid state power distribution module. Motors with the same CFM would pull 25 amps when we would need to be under 20 amps. The nice thing about them is they soft start and we can control the speed curve against the coolant temperature. I plan to do this with my units, but I also got a pulse width control box if it ends up not working out correctly, or if I need to override. Or to look at it another way they can flow more CFM for the same amperage.

The boss man gave me this for free when I asked how much it was, so I chucked it up and spun it down to fit:  Its bigger than stock, so I'm curious to how much this will affect it. Stock idle is 750rpms. I run at about 1500 for idle now. So I think I'll be okay. But I know jack poo poo about it. And uhh, I think I'm going to try and mount a bank of these to replace all of the big relays:

Powershift posted:I would want to make sure it's designed for vibration. If there exists an I/O configurable solid state device (PDM), for under 500 dollars I'd be all over it. Everything seems very restrictive without going to the minimum of a Racepack or to the desired Motec. And by configurable I mean just running input triggers to power outputs. Seems to not exist. However I am looking at just running a nice conventional block like this: https://www.waytekwire.com/item/460...U8aAsYMEALw_wcB sharkytm posted:Those SSRs are junk, and the ratings printed are :cough: optimistic :cough: I figured these things get hot so I may look at just running them at half their rating.

Testing the relay for 30 mins and it was still cool https://www.youtube.com/watch?v=W9gTdcgZAEA it would be awesome to use these if you think that the TE versions would hold up since they are potted.

Here are the TE ones. I'd like to run these for the fans, and then get an automotive Eaton box for everything else. They aren't automotive rated, but the data sheet and the vibration resistance instills confidence in what they have. https://www.mouser.com/new/TE-Connectivity/te-pb-solid-state-relays/ edit: I keep looking at the PDM60. I could possibly use it for the fans and fuel pump. The trigger options aren't great. Ignition, battery, and ground. There is ONE ground trigger for all of the outputs. Maybe ground for fuel pump, and ignition for the fans since they are PWM. Everything else can go on an Eaton. Aeka 2.0 fucked around with this message at 19:41 on Nov 23, 2019 |

Lol. Ok just noticed that there is a new PDM60 called the Amp link and it has more triggers. I think that's the jam for a couple of fans and fuel pump. edit: gently caress IT, im getting a Motec PDM.

As with any project when you don't know what you're getting into you make sure you rear end will hurt later: I had to re do my fan shroud on the fact that I hosed up the first one, so I had to turn to an expert and best friend to make poo poo happen after I did the cutting and bending. His home garage is set up for any project.  https://i.imgur.com/xi911Zt.mp4 And still the king of pulse MIG welding. From what I'm told, Miller bought the Panasonic welding division and buried it.  All ready to go. I used race space super nascar 3m metal tape to fill the open spaces if you're wondering.   Checking V-Mount fitment. I still need to modify the brackets and move everything up a little bit so I don't bottom out on the setup.   Motec PDM 15 ordered and I've been working out what needs to go through it.

IOwnCalculus posted:I received a narrower Husky box from that same lineup from "my kid" for father's day. It's surprisingly nice and arguably a better deal than the HF. So far it feels pretty good. This thing costs less than the craftsman I already have and it feels better, but it could be that I need to re lube the bearings on the Craftsman. I'm not used to deep drawers so this is a treat.

Yeah im going to keep focusing on the wiring for a bit. Between what needs to go to the PDM, the Relay Box, the fuse distribution block, and what gets tossed, my gears are burning whatever wd-40 i got left for brain fluid. I'm used to doing off road cars on the daily, but being mindful of things like hidden splices that power air bag modules and other weird poo poo kind gives me anxiety. All I can handle is about 3 beers of it at a time.

My water heater, which is one year old, which replaced the old one that flooded my garage, has developed a leak and the gas regulator or something related randomly harmonizes some high pitch noise, it goes away when i turn off the gas. The pressure relief is working fine and i ruled it out as the source of the noise. So I had to push out the car to the driveway and now I await the original installers of the water heater to take a look. gently caress!
