More dollars than sense?

On another note, it has been raining and I wanted to see what happens if I "lead foot" it. Weeeeellll, the nanny cpu cut power and I did not get the expected result it did accelerate though. So I turned off the monitoring and powered up again. The wheel spin was so fast there was no acceleration. The wheel just spun and the T4R went no where. It was very interesting. I wanted to try 4WD but chickened out.

Installed my kit a few months ago and it's exceeded my expectations.

Are you going to put an oil catch can on it?

Probably not, just going to run it as designed.

She's a beaut, I enjoyed reading your journey to getting the URD charger. I am on the waitlist until they are back in stock. Thanks for sharing.

everytime this thread pops up, I want a S/C for the minivan. thanks

So I figured out the relay trigger I had to the fuel tank that ran the surge tank pump was draining the battery. It appears that functionally Toyota is triggering the fuel pump when the ignition is off. Maybe something to do with the fume purge tank. IDK

Symptoms were the Surge tank pump running when it was parked (no key in ignition) and the battery being drained when sitting in the garage for an extended period.

I moved the relay trigger point to run off the Supercharger intercooler pump. The red relay wire is power to pump. This relay is triggered by the ignition system (URD designed) As a side benefit as I understand things, If the car is in an accident, battery power is cut to the ignition system. Thus the fuel pump will stop running when ignition system is powered down.

If there is anyone with better knowledge on this safety setup please let me know. In other news MPG is down to 18.7 in the city on winter gas . The supercharger makes gear pulse noise when stopped at a light and I don't think I will be getting a gen 6 when they come out

Great research. I had the same issue years ago with my URD. When I was driving the 4R every day it wasn't a problem. However I travel extensively and once upon returning from a long trip the battery was dead. Thank goodness I had a second battery and also carried a Noco. That issue got worse and worse as it sat and we worked on other things. The supercharger was great but it's living on another 4R in SoCal now.
