electric deck lid..just made one!
boof2332 - March 21st, 2007 at 12:24 AM

I have always wanted my deck lid to open and close depending on heat/rain etc. I finally made one using 2 wind out electric seat motors from an xr6 turbo. It sits shut and opens the same amount as "stand off's".

With the rexy motor not needing air in the engine bay like an aircooled engine, it is more for look than anything....it looks pretty cool. Just waiting to see someones face in traffic when it opens and shuts.

Three of the boys popped out today and i have to make three more which I will attatch via the stock mount points. The way they work means you can open the lid the same as stock whether in or out.

Any chance you could put some pics up ? iv been thinking of this exact thing for aaaaaages. i want to use it in combination with a hydraulic piston to open the deck lid remotely.

That's a farken sweet idea! :tu:

VWCOOL's prolly worrying how he'll stay in business right about now! :lol:

I am acually just about to jump on a plane and will be away for a week. Will do when I get back. You can buy lineal actuators that move from 2 inches to 10 depending on how much you want to spend.the little ones are about $125 each.

So has this kept the rain lip or did you grind this off?

Well done though :tu:

lol.. looked at this idea 15 years ago using first-gen MX-5 headlight motors and there's been plenty of discussion of this on SBO in recent months.

But no matter what else comes along, Hoodjax cost $80 and take 10 mins to install... :thumb

But great work Matt! I'll drop by again one day for a look-see and to talk sheit

I have also done this with my turbo54. No rain lip. I would love to see how you have hinged it at the bottom to be released quick.
The way I have done this is totally simple for my car. I am keeping this one to myself until car is finished but let me say it auto opens and shuts when the car thrashed.

pics pics pics...all talk and no evidence. :P

i was thinking of using a air flow meter or something, either underneath the car, or attached to front apron. and connecting it to a PCB, to program it so when it gets to X meterage it'll activate the motors to open the decklid, and when it goes back below a certain X meterage it'd activate the motors to close it again.

i suppose you could do it off engine RPM or speedometer as well. if you had a carputer onboard you could run it off multiple settings. IE open when engine/oil temperature reach X amount. open it when sitting at a standstill (at an intersection, so the engine can breath a little better and not heat up). open when an airflow sensor is activated at X amount.

even close when a rain sensor is activated (can be salvaged from late 90's mercedes, bmw, porsche for cheap).


so many ideas, so little time and money to implement them. :(

I love my Hoodjax! :P:thumb

Aww, thanks babe! :kiss


boof2332 - March 30th, 2007 at 03:32 AM

Back from Noosa..how is it a break with 5 yr old boy and 2 1/2 yr old girl...

Wired the lid up properly today...little switch on dash if you hold it down the lid comes in and vice versa.

There is no rain lip although hinged right it could open down and out and maybe keep the lip. I was thinking it would be best temp operated on an aircooled motor, either intake temp or oil temp. I was going to have it air intake temp sensative, however it will now be open always when driving except when raining.

Glen, I have always loved your little hood jax too..:kiss

Hi Matt,

have you got any pics yet?

Cheers


Beerboy - March 30th, 2007 at 10:21 AM

Agreed we definately need pics mate.


Turbo54 - March 30th, 2007 at 01:36 PM

I will let the cat out the bag, mine runs off boost referenced pnumatic shafts. Car comes on boost - out pops bootlid, when stopped at lights etc the lid is in to keep the boys in blue off my back.

pete wood - March 30th, 2007 at 03:15 PM

can someone post a pic please, this is very frustrating.:rolleyes:


boof2332 - March 31st, 2007 at 02:36 AM

Nice one turbo 54, I knew you were dying to tell someone. How much psi does it take to switch the motor??

My revised design for mass production, with free installation by glen at the nats will also use a lineal motor.
The winder is smooth but a bit slow..takes 5 seconds.
Ill take a pic tomorrow...


greenman - March 31st, 2007 at 11:48 AM

Sounds interesting. Keep us posted please.

So in every gear when you hit boost, the lid will open?

You'd be better off having an RPM trigger, say at 1500-2000rpm (use one of your outputs on the EFI computer you plan on using - unless your computer can register speed) so that once your moving the lid is opened until you come to a stop - sort of what porsche's do with their rear spoilers (can't remember which model it was) but theirs is speed triggered.
Otherwise the decklid is going to be continually moving in and out.......

Cheers

the porsche carerra GT does that, it activates at 85mph.

and as jeremy clarkson of top gear said,

you may as well hang a huge red flag off the back of your car that indicates I AM A RICH WANKER AND I AM SPEEDING


temperature seems the best bet IMO


boof2332 - April 1st, 2007 at 06:16 AM

I think turbo 54's opens under boost then stays open till it stops...is that right.

I will take a pic tomorrow of the winding mechanism and how it attatches to the decklid. Mine has had the hinges cut out, although mounting off stock points with my design would be heaps easier than what I did.

I want to make a kit to sell, just got to find some lineal motors for the right price..that will be the key!

Turbo54 - April 2nd, 2007 at 09:41 AM

You got it boof, comes on and opens at a predesignated amount of boost like 4psi and stays open til I take my foot of the gas, as boost wont fall beneath 4psi between gear changs it should stay open. I cant be bothered with motors etc, just extra weight. These are pnumatic push rods that work like gas struts that hold bonnets up.

So what happened to these pictures?
I know I am very interested in some of these action shots.
Maybe a movie :D

An Update?

sounds like a gee up.. no pics as of yet.. im sure theres a mobile phone about for a pic hey..


Turbo54 - April 17th, 2007 at 09:17 AM

You can all wait til the cars finished, not gving away all secrets until its done. I told you how but I'm not going to show you.

Turbo54 - February 18th, 2008 at 04:09 PM

Just to let you all know that this is coming along well. It is have getting the angles right for the lid to open smoothly but the mounts for the rams should be on the CNC machine by the end of next week. Will post some pics of the mock up mounts and rams in the next couple of days.
