OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

Do you have an updated ETA on shipping?

 

Not yet sorry, waiting to hear on downpipe ETA. They are in Fab right now, full swing.
My goal is to start shipping this month

 

@OVTune while your around any eta on your new Tune cables?

 

The Wi-Fi cables? September.

 

Great. Thanks

 

What is the deal with downpipe selection on the first batch?

 

catless.

sorry clarification, catless versions coming first.

 

Have a lot more videos coming.
quick video trying to show acceleration from a stop to about 95mph.
traction control still engaging in first when it starts spinning as you can see, cutting throttle (you hear the bpv twice)
video isn't edited or anything nice atm.
The turbos feel barely alive @ 7psi

powermax, about 7psi.

and youtube makes my 4k video look like a potato.


log >
traction control simply wont let you give it all in first

 

I bet a 4wd would solve the trac control issue
Awesome to see a taco move that fast though. Exciting stuff!

 

How much power can transmission, transfer case and rear end all handle without reliability concerns?

 

I recall the transmission being "rated" for somewhere in the low 300s ft/lbs

 

Lol

 

I'm trying to find a reference but I'm having trouble. I think Aisin makes the transmission..

:::EDIT:::

Found it. Aisin AWR6B45. I'm calling that 435Nm which is 320 ft/lbs. Here is the source. Preview the document, it's on page 5. https://www.sae.org/publications/technical-papers/content/2016-01-1097/

 

This STILL isn’t available??? HO-LEE-FUCK

 

Adding FI then sounds like a disaster waiting to happen. If toyota made one like they did for the 4.0l it wouldn’t scare me as much since they stand behind one. But for a daily driver guess I’m to chicken for this game.

 

how do they find this number?

My assumption is most of these numbers are provided by completely binding the trans until it breaks under a certain torque load?

 

?????

 

He thinks Toyota made the supercharger they bolted on.

 

Idk, they make tranny dynos. There's a dude on YouTube with a AB60 tundra trans on the Dyno.

 

These numbers are likely based on safety and a given lifespan. With enough use, everything will fail even when used properly. Increasing power will inevitably make that failure a bit sooner but I don think there is too much to worry about here.

Safety margins are everything. No one builds something that is going to fail at the rated spec. A common value is "1.5" which means that if the design was 100ft lbs, it would be slightly over engineered to hold 150. Seat belts and rockets are both interesting on this topic. Seat belts have a margin of something like 20. In contrast, space travel is very expensive so they often use 1.1 or less.

My guess is that the transmission is somewhere around 2 or 2.5 (640 to 800 ft lbs) however this is just a guess. Also note that this would not be a working limit but rather an absolute limit.
