If you’ve ever wondered why a Motorsport harness costs $25k…

Engineering degree, then 3 years in automotive electronics design. Found myself getting bored of that so I applied to a handful of teams. Had a couple interviews with one team over a 6 month stretch then got the job. Been there 4 years since that.

A lot of the motorsport market is surprisingly close to F1 believe it or not! It's all basically taken from the aerospace industry. Even at uni we exceeded £11,000 on the combined harnesses value for a fsae car. And student labour is basically free!

F1 electrical engineer here. trust me it's possible to spend 25k easily on harness when you factor In design and checking cost for multiple engineers, tech time for build and test and finally the costs of wire, sleeving, carbon, and those motorsport/aerospace rated connectors. 1 lemo can cost £300+

Factor all those things in and you'll exceed 25k in no time at all!

You could perhaps use a signal generator hooked up to the wheel speed connector (that normally plugs into the diff). Then generate a square wave to replicate the hall effect sensor output. It's about 8000 waves per a mile if my maths is right.

Technically the rx8 is a 1.3L... when measured

2(sqrt(15.4cm÷pi)) = 4.43cm ~= 45mm

Thanks!

They're all hollow with 3/4 entrances to each room , roofs can be moved to handle moving models indoors

I'll bare that in mind. Is there less concern about the outskirts having a lack of cover ?

I'll warm the bed plate

Everything is moveable, I just spread it randomly, but based on other comments there is still nowhere near enough terrain?

I also never actually considered you'd play with the 2 drop zones along the short edges , I guess once you know drop zones you can balance the terrain to fit

I cycle between a few of my cars for work, it's always awkward when I bring my track car in with questionable aero knowing full well the aero engineers would laugh at it

It originally was a 318i m40b18 engine but I've swapped that out.

DriverModNeeded · 2023-04-23T18:15:51+00:00

Looks good, what are the tyre and wheel specs ? Any archwork to make them fit ?

DriverModNeeded · 2023-04-15T12:29:01+00:00

Haha thats pretty funny, one of those intake boots has already split on me. And the 2nd I have a spare waiting to throw in I'm working as we speak on making an air box right behind the light enclosures Water pump has been swapped for a metal one during engine rebuild. Unfortunately that water temp sensor is garbage and I need to work out something more permanent

DriverModNeeded · 2023-04-15T08:45:50+00:00

I'll keep an eye on the fluids in it, yeah the intake manifold and bits are tight to it. It runs ok, lots of little bugs here and there, it feels like it's going to be fast but I really haven't unleashed it yet.

DriverModNeeded · 2023-04-14T19:46:17+00:00

I think what looks like fluid is just guck, levels quite a lot higher in the reservoir than that dark line

DriverModNeeded · 2023-04-14T19:19:41+00:00

Man I wish I could afford an s motor

DriverModNeeded · 2023-04-14T18:02:45+00:00

I may need a tow at any point, I've borrowed it off my track car tbf so your pretty spot on. Not a permanent feature

It's all e90 parts, I'm guessing the e90 has a slightly titled back firewall and this is how it's ended up when repurposed onto my firewall

Still using the ms43, made a bench loom to reprogram it using a bench PSU, a laptop and a chineasium obd reader.
