Definitely felt that heatsoak today, I believe ambient hit 90s today, definitely spent some time in high 80s. The Torque BT adapter is in the mail, can't wait to log some atrocious IATs...

Finally bled the system through and the car came down for the first time in a month. My fears were partially true, the MC size and the lever math makes for a tough time locking the rear wheels. I will either have to go to 5/8 diameter Wilwoods or (and this is what I'm thinking), come up with an adjustable pivot point system for the lever. Due to the geometry of the assembly simply drilling another hole might not be an option, but I will exhaust the simple solutions before I move onto redoing the plumbing itself or machining a new lever from scratch.

The biggest lesson of the day, however, was without a doubt to check the dates on the used car's tires before doing shakedown drifting. I'll let the photo do most of the talking, but the tire manufacture date indicated 4011, which is quite a bit past it's shelf life.

Adjusted the lever pivot point for a roughly 20% improvement, not nearly goo enough.

Did some more math and decided I'm going to 1/2" ID Wilwoods. This will reduce swept area (and thereby linearly displaced volume) from 0.44 sq-in to 0.19 sq-in. That means 2.3x more clamping force for same lever effort, also making the lever travel 2.3x as far.

Sounds about right, but I'm running out of time. The car is already entered in the event on the 28th, so I had to do the quickest available Amazon shipping option. If this doesn't pan out, I'll have to be machining a new lever with completely new pivot points, possibly even longer and also likely will need new side brackets for the hydraulic box.

Meanwhile the Vales and Direzza102s are on:

Those wheels look really good, what are their specs?

TSW Vales: http://fitment.tsw.com/alloy-wheels-...model=E55+W211

32mm offset at 18x8.5" and the P\N is 1885VLE325112B72. Square fitment. I use 245mm/40 rubber on em.

Bluetooth OBD adapter is here! Time to pay for Torque.

C32owner

Amazing app that for the money. Well worth it, to have a look see what's happening.

jumph4x

Worth it just for the IAT logging alone.

C32owner

For sure that and checking you boosting OK.

jumph4x

Crap! I hooked up the steering wheel controls circuit and the buttons do not work!

I needed that to be able to get into the dyno mode. ****, ****, ****. Think, think. I am not sure I have enough time to code this all out in CBT before the event which is coming up in a week.

Forget the buttons and focus on what the buttons do TO the canbus to trigger DynoMode.

Those inputs don't need to come from the steering wheel right now.

jumph4x

That's my fallback. But having a laptop in the car while staging with a helmet on is... not ideal.

BC928

True. Its cool. But not ideal.

If the CAN network is "senthitive" how you chose to create inputs may be not accepted, and an error code logged. Can you see these? Do they exist?

jumph4x

Had to step away but will come back to it tonight or tomorrow.

Hydraulic brake is done-ish. After putting in the 1/2" ID Wilwoods, replumbing everything and fixing a stubborn leak, I'm finally able to enjoy the fruit of that labor.

Did some IAT investigative work and all I have to say is 'wow'. I logged a 115C (240F). This seems insane. After my first event I'm immediately making that priority #1. As a recap, what I have planned for that is a new IAT sensor, splitting the plumbing, new heat exchanger and new pump. Possibly a manual override relay to make it run from a switch (or fulltime).

EDIT: for the life of me cannot location a +12VDC constant for the headunit, so when I shut of the car is does the infamous pop of speaker ruin. Tested every wire available back there, they're all switched. What do, where is the nearest source. halp.

240 is nuts man SC shuts off at 200, that makes me think something is up with your pump or you need meth installed asap to do what you are doing

I used a coupler off a fuse for 12v constant in the drivers side fuse box and just ran it up and over. The one behind the plastic panel. Just read about whats what and pick one that not too intrusive. Most all those are 12v constant

jumph4x

Sounded insane to me too. Rumor has it that the IAT failure mode might be high readings until an eventual short, but who knows... Waiting on air filters in the mail to begin on all that.

hey jump, you may want to take a look at this and replace bolts and reinforce proactively with what your going to be doing with the car -- good luck and interesting build

Beautiful pics man! Great job

Thanks!
Please explain!

So much win in this thread...

That steering wheel and hub came out really nice.

Cutting the next episode.

jumph4x

I just took the car to it's first event. I was anxious and nervous for months. I bring great news: it definitely drifts. Feeling very wholesomely happy and validated right now.

I have quite a bit of footage to cut into some episodes. Stand by, team!
