Window Rocket - who’s tried it? (4 Viewers)

[NorCalFJ100]

We need to talk about the difference between voltage and current and their relationship with resistance.

When you push your power window button the electrons flow through the wires. That electricity makes the motor turn, but also makes heat throughout the circuit.

The window motor has a set job to do. It has a fairly fixed load moving the window up and down.

If you power that motor with 10VDC it's going to use a lot of current to move that fixed load. If your windows are slow a big part of that is because they want more current than the wiring can provide to do the job.

If you power the same motor at the same load with 14VDC the motor needs 30% less current to do the exact same work.

Less current flowing through the wires means the wires are generating less heat. The resistance of the wires doesn't act directly on the voltage, it resists the current. When the voltage getting to the motors drops it's the consequence of the cumulative resistance throughout the power window circuit choking off the current available to the motors.

Make sense so far?

There's not a whole lot we can reasonably do to lower the resistance in the power window wiring. All we can really do is replace the undersize power window relay.

So we do that and now the windows can get a bit more current. But the windows are still slow. We made maybe a 5% improvement and we're still forcing the window motors to run on a less than ideal voltage.

By raising the voltage we're counteracting all the resistance in the power window wiring. All the plugs, crimps and switch contacts that aren't perfect after 30 years. Raising that voltage up means the motor uses less current to do the same job.

Additionally, and this is a big one, the actual load on the window motor drops dramatically when window speed reaches a certain threshold. This threshold has everything to do with how the window seals act on the glass. I believe Toyota engineers either overlooked this relationship or misunderstood it when they designed the 80 series window system. I suspect they believed slower would last longer. And I believe they failed to account for how the system would age in time.

So I need you guys to understand that while the windows are going faster, the Window Rocket is not doing it by working the system harder. All the wiring in the window circuit has a much easier time running with the Window Rocket VS without. The wiring is dealing with much less current, less heat is generated. The physical load on the window regulators and motors is LOWER when they are going faster because of how the window seals grip the glass at low speed.

You don't need to take my word for it. Look at the window speed of every vehicle made in the past 2 decades, including every Toyota.

I have no plans to add a rheostat to change the window speed. The fastest it can possibly be is the same as every modern vehicle. It is not too fast.

SOLD! Just placed an order. Everything in my doors is new and still lack luster speeds. Looking forward to this. Thanks!!!

I get a chuckle every time I drive my cruiser now and hit a window button…simple pleasures of speedy windows! Thanks again @PIP for a great product! Now to fix my munched front differential gears from my last trip, wish that repair solution was just as easy…

Drove mine this morning and probably rolled the windows up and down 30 times for no reason at all

Before I installed Window Rocket, I avoided rolling windows down, because there were times, they wouldn't go back up and that's a problem in bad weather. Now - no problem - except I pray the limit switches don't fail...it' always something, right?

The latest revision of LHD non-ABS Window Rockets have been tested, they fit great. FJ80 Window Rockets will be ready to ship when the kit hardware shows up and instructions are finished.

FJ80's use one existing hole and two self tapping screws to mount exactly like the ABS computer mounted in later years. A 93+ 80 series without ABS will have threaded mounting holes and a stud, the Window Rocket will bolt right in.

The RHD non-ABS Window Rocket mounts are ready and will be test fit later this week.

I just installed one. It is great! I replaced window runs, motors, and regulators on my 93 and they are still slow. Also, one of the new regulator gears stripped after a few weeks on a new, Aisin part. On my 94 I installed the Window Rocket. Astounding performance! If your windows get sticky but are otherwise fine, install the Window Rocket.
