Official WOTBox Install DIY

[lulz_m3]

I had the wotbox on my old car for over 4.5 years, not a single issue relating to the wotbox was had.

@tony:
Everyone knows the N54, N55, and S55 crank hubs are not keyed.
It's a real possibility that the rapid RPM fluctuations from sitting on the 2step loosened my crank bolt enough for the timing sprocket to slip. I had my WOTbox set at 3,500 rpm and logs show rpm jumping back and forth between 3,200 and 3,800 rapidly. I ran my car at 19-20psi for a good 10k miles without issue, doing pulls, banging gears, not exactly being gentle and it had no issues. Then when a mere 500 miles after I install WOTbox carnage happens, I think it's pretty clear what caused it even if the exact mechanism is unclear.
However, if other members have had better luck, so be it. I don't drag race anyways, so I'll just learn to launch better without needing to build 5+ psi of boost.


@bigdnno98:
I had the stock DMFW when it happened. Do you think you could post or send a log of your rpms on the 2-step?

Not possible. That was 5-6 years ago and 3 computers ago. Sorry

Damn, DMFW? That crushes the idea I had about vibrations.

@veer90, what have you done to the mounts for the vehicle? Engine mounts, trans mounts, flex disc, differential mounts?

Has anyone balance their crankshafts? @alex@ABRhouston, @Motiv guys (not sure the engine builder for you guys is on the forums) what are you seeing when you are having the engine built? I know the bed-plate has to machined after removing it, but are y'all balancing the crankshafts?

Some good questions here.

Let's tag @alex@ABRhouston again.

At the time, the only upgraded mounts I had were transmission (UUC black), rear polyurethane diff and subframe mounts (SuperPro), and the revised BMW guibo with an aluminum body and smaller rubber bushings. Motor mounts were stock.

After the slipped hub got fixed I upgraded to polyurethane engine mounts (ADE) and will be running a SMFW and upgraded turbos.

Can anyone in this thread send me a RPM log of their 2-step in action? It's possible the WOTbox itself may be faulty / screwy since I bought it used and have no reference as to how it should behave.

Yes of course the rotating assembly is balanced. Typically almost no work is needed. We balance to .5 gram- crank/rods/pistons, and if the client has a flywheel/pressure plate available- it, too at the same time.

Is this possible on a auto?

Why would you want it on an AT?

Haha, you know why. Bang pow pow sounds.

It's not anti-lag. It's an RPM limiter.

Ether way I would like to have it my turbos are smoking so their going out an i wouldn't liken to end their life in a fun way but not sure how to install this on a auto I have seen videos of people having it on a auto they just hasn't showed how something to do with cruise control on something

[Abuell5]

Can anyone help tell me if I hooked my ignition wires up right? Also my yellow rpm wire is all wacky when hooked up and reads way above on rpm or reads none at all

[fury taylor]

I just got my wot box I installed as such but instead of a red /black wire it's just red but after install tried to start the car cranks but will not start

just to be sure..

RPM source is X60005 large black connector Pin 29, CPS-Signal.
Is it not the crank signal?
