So I ditched the solenoid-based idea, it just didn't open fast enough (also more expensive, scarce parts). So I went to looking for cheap geared motors, and it dawned on me - use my spare EF wiper motor!! It needed some work due to the gearing (inertia issues), but its really fast and shouldn't burn out (OEM honda, y0!).

All I used was a mustang throttle body, 2 microswitches, a 'dpdt' relay, and a cheap 60" throttle cable. And lots of screws & metal... Time & material for me was still less than a slow-*** $150 cutout. The best part is my cutout's motor only draws power when moving, not when parked. To activate it you simply turn the relay on, i.e. ground one terminal using an eCtune GPO...

Blah blah blah. So how fast is it? Watch the videos:

FYI this is "low" speed; the shaft spins with 50% more speed & torque on high. Not bad for a $19 hacked CVS camcorder.

Here's the ON-CAR test, same $19 camcorder (sucks with the high volume)

For reference, here is a bling'in wireless e-cutout that takes a full 5 seconds to open

Yes, zipties might help

Thanks for the idea, I can now put some of my extra old throttle bodies to use.

why not use a door lock solenoid?

I was going to say the same thing. I have one somewhere in my appartement and it open pretty fast.

First off, they're expensive vs a $10 wiper motor. They might be fast, but you also need decent power over a long travel (long for a solenoid), or create a cantilever system. They would also have to be rated for continuous-duty, or they'll fry (or you need a 2nd parking solenoid). The way a solenoid works is the coil is an electromagnet, and that pulls/pushes a metal shaft. The farther away that shaft is, the less power it has. The solenoids I have give 210oz (13lbs) of holding power, pull 125oz with it .05" out, 20oz at .50", and 5oz at 1.00"; that doesn't account for friction around the shaft, cable, etc.

Long story short, door poppers are good for popping doors. :P It would involve a similar amount of work, and cost more.


Anyways I got my turbo EG all bolted up again, and its the quietest Civic I've ever owned - better than my bone-stock CX... until I flip the switch.

i want to see a picture of it installed

Not all that bad https://www.directedstore.com/cgi-bi...ategory%3DA_SE

But still very cool what you did.

If thats a motor, you still need the limit switches. I would guess DEI brains only send power for a second to prevent burnout.

I'll have *working* installed pics soon, I just had to roll the car outside before routing the cable. I never thought when I got my first Honda I'd be happy to have a QUIET car...

Looks nice. Where did you end up mounting the motor to run it?

HiProfile

I have the motor in the trunk. I found a nice hole on that sill just behind the seat, and it goes straight down to where you see it in this picture. Those Honda guys read my mind - it was freakin perfect.
