Focused on some progress this weekend, bypass pretty much done and TB mount made.  Throttle body harness built.  Don't have any free analog inputs in the EMU black ecu to monitor the throttle position, however this ecu is expandable with CANbus analog inputs; so I'm going to look into making a basic analog-to-CAN device to bring in more analog signals like the throttle position and whatever else I want 0-5V.  Otherwise, parts ordered or about to be ordered for upgrading all the cooling hoses and oil cooler lines.

Good job.

Given it isn't a critical DBW input, just using a single track on the unit would be fine for position, instead of the typical dual track needed for safety on DBW

Thanks guys!   :D


More updates, I have a check list of stuff to do, to help direct me because I go crossed eyed in the face of this haha



I'm taking the risk to run without the IC cores in the LSJ intake, I designed and commissioned a block off plate, made 2 because the cost of 1 was nearly the cost of 2. It will certainly reduce any pressure drop across the laminov cores since they're not there. Going to lean on water / methanol injection to help with cooling the charge here in-lieu of the heat exchanger.







New water methanol pump.  It didn't start up this season, eventually kicked on though.  Since I'm going to be leaning on water / methanol (water only on track), I have to replace the pump to ensure reliability.



Cooling system hoses upgrades, I priced out building the 'ultimate' lower rad hose out of silicone with the Tee and bends, would be around $300 so sticking with the $150 continental lower rad hose.  New DDM upper rad hose, next to the 15 year old Werks hose (which is thicker). 



DDM small bleeder hose kit also, nice molded like OEM, and price is good compared to trying to build your own with time saved.



My method to refresh OEM clamps, coat them with zinc spray, cold galvanizing





All lined clamps from Zoro (ideal brand) found a use for the 20% off coupons, lined for silicone hoses.  A bag of pinch clamps too for more permanent heater hose connections.



So many choices, I just went with all Redhorse PTFE 10 AN, decision tipped because they make hose ends in the natural finish and matches the stainless braid better, idk sounded good at the time.

Noticed oil seeping around the front of the rocker cover, replacing the gaskets I noticed a potential root cause of the leak: broken spacers missing the washer portion to push on the rubbers to hold the cover on. 

These are $6-12 a piece to replace!!  Then I designed that spacer detail in CAD and started looking at online quotes, like 100 pieces or something because it seems like other people are seeing what I'm seeing.  Bad idea, $16-20 per piece at 100 pcs.  Then I went to rockauto.com, and they have them for $4 something, so the order is in for a new set.


Look at that trash metal they used what is that?  Stamped / formed steel can be that brittle?!

I'm going with cast, look at the grain structure in the close up pic.

I think I was thinking initially the radial cracks were from the stamping process (stretch marks), yeah makes more sense it would be cast or maybe even sintered?
