Tezla electric water pump (yes with a "z") uses a 3/4" standard American heater hose

[Gregski]

it needs to attach to the radiator outlet which is lets just say way bigger ( 1-9/16ths for those of you keeping track at home)

[Gregski]

now the fun continues as the 3/4" hose from the Tezla water pump has to now mate with the 5/8" Lexus inverter inlet, joy

the inverter is arguably the most important metal box in the entire jigsaw puzzle as it convert DC direct current stored in the BMW batteries into AC alternating current which the Lexus motors consume inside of that unicorn of a transmission

[Gregski]

so back to fighting with that Honda CRV electric brake iBooster, the darn thing pulsates when the pedal is fully down, I just don't get it, I know it was designed to work with only disc brakes so maybe there aint enough flow

but I tried capping off the rear brake line at the master cylinder and pressing the pedal to only engage the front disc brakes, and the pedal still wiggles when fully down to the floor

I even tried by capping off both outlet ports on the master cylinder, still no dice, is it air?

Did I miss how you plan on heat defrost etc and cooling transmission just interested on how your planning that if it’s in a post pardon me please

excellent questions

no heat / defrost in Phase I of the implementation, I live in California (pronounced: Spring, Summer, Fall, repeat) however if I do decide to add heat it will be via an electric heater such as the one from the Chevy Volt

as far as cooling the transmission I am going for the belt and suspenders solution, first like any traditional automatic transmission it is plumbed to the radiator's transmission inner cooler that is integrated into the regular dime a dozen Chevy type radiator, then in addition to cooling the transmission fluid this transmission has water cooling built in, so those hoses also run to the regular car radiator (same one) but to the regular water inlets and outlets

all this gets recirculated via a Tesla Model S electric water pump

hope that hels

and this is what a $150 bones worth of hose reducers, couplers, and thing majigs look like

[Gregski]

some trial fitment going on here, I do plan on cutting the 90° elbow shorter to bring the hose closer to the Inverter allowing me to use a hose clamp off of it to secure it so it's not all up in space like this (by the way that's a Tesla Model S water pompulator)

the Inverter is a metal box that changes DC Direct Current stored in the BMW batteries to AC Alternating Current consumed by the Lexus motors inside the transmission

[Gregski]

same on this radiator inlet hose, this is coming from the passenger side of the transmission and I hate that it has to run across the engine bay under the battery pack, wish my inlets and outlets on the radiator were on opposite sides (how could Genereal Motors not envision this back in 1967?)


this 90° downward elbow will also be shortened and brong over closer to nearly hug the radiator, this again is just some expensive brain storming

this hose will eventually not come out of the battery pack but run in front of it closer to the radiator

[Gregski]

yup, so I tried to cheap out on one adapter and it bit me, here I was trying to connect a 5/8 water pump hose to a 7/8-1 1/2" radiator reducer and no dice, so what you have to do is go 5/8 - 1" reducer to a 1"-1 1/2" reducer to the radiator, oh well this gives me a chance to order a 45° reducer instead of the straight one so there's that

ha, ha yup, that reminds me the proper radiator lower metal support brackets and rubbulators showed up

super kind of you

thinking about ditching the Gen 1 iBooster in favor of the Gen 2 ?

cool work. have you considered a electric power steering pump to run hydraulic hydroboost style brakes? if that is an option just would have to look at power demand that way?

keep it up bud awesome work!!!!

Thanks Sean the EV Community is graduating from electric power steering pumps on the account of them being noisier than the entire electric vehicle and adopting actual electric steering assists from the Prius, please take a gander at my video series on the topic here:

yeah you should have, I have allowed strays into my house from the forum before, my wife asked one night "what if he is a serial killer" and I asked the guy that and he said, man I wish but I'm just too busy and that takes a real commitment, we all had a great laff
