On a different forum I posted the question about a quick-release belly pan, since many folks have to remove it often, and I'm lazy. Someone suggested Dzus 1/4 turn locking fasteners, but I have no idea what that actually is, I didn't bother researching. Is that something that you could incorporate into your design, or something that could give it a quick removal?

 

i was considering making an undertray pan myself, considering i currently don't have either the front rad undertray or the aero tray at the moment. but i would for sure be interested if you did most of the hard work for me

any idea on cost? you said you would only be selling the template?

 

what does the orignal aero tray look like please someone post up a pic

 

As Gatlin suggested, 1/4 turn fasteners would be sweet. Unfortunately, they would require replacing all of the welded in nuts with 1/4 turn sockets.

 

No I would be selling the piece itself, I was going to make a Die so the process would be repeatable... that is why I was worried about the cost of producing a die.

Making it a quick release would not be very practicle as you would have to weld the quick release specific nuts into the Engine Craddle (k member). And for most that isn't "bolt in" so that just would not be practicle for most people.


SnowmanSteiner;
The aeropannel will work just as well as stock(perhaps better), the ducting will work better than stock. But no I do not plan on setting asside a week of my time to do the measurements and calculations, as most people will not require anything better than stock as far as the drag coefficient goes or downforce for that matter.

 

Since there are so many aerodynamicists or aeronautical engineers, etc. looking at this, I was curious as to what could possibly be done to make the undertray produce downforce or improve the drag? Dimpling? Or would you have to use two pieces of metal to make a longer type wing? Or would some type of venturi work? Naturally, I'm a total layman, so I'm assuming it is all about shape, so I could be totally off. However, I'd still appreciate the "engineers" perspective on this.

 

You guys talking about something like this?





Something like this would be fairly easy for anyone to make in a afternoon, and fairly cheap too(depending on what material you decide to use).

 

I might be intrested in one depending on the finished project and price.

 

That looks good. I've been planning on making a similar pan that will direct as much air through the fmic/oc/rad as possible.

 

that looks almost identical to what I have made, only mine is two piece.... but the ones I want to make will be One piece as well.

also I see that you still have the stock underbelley aero tray, so in addition to what you have there, there will be a piece between the bottom of the raditor and the engine craddle (k member) so that it will not interfere with the sway-bar flex, as well as the steering assembly. Just another piece to force air to go where I want it to.

Yes it could be done, but I don't think most people are willing to pay the price for all the time and design and testing to prove it. this piece will improve downforce in extremely minute amounts, as well as decrease drag coefficient.

 

I think Higgi made the above aluminum tray. I like how it doesnt cover the steering rack, sway bar, and oil pan. Only goes up to the point where the radiator ends. Makes it easier to access some things.

 

the piece I have planned will be another piece entirely seperate, and will most likely be fairly easy to remove.

56-11Y is stock alu panel under oil pan, which does nothing else then keeping your leaking oil from dripping down

what makes sense to make/sell and is important to have is the plastic undertray 56-111B

Either stock one or some replacement which does same thing (keep air going to where it should - coolers and not around/under them)

On all our cars with FMIC's we are seeing big differences in temps and ability to keep it cool with every improvement we do in those undertrays.

 

I still want one like hIGGI's, it's hawt. I need to get off my lazy *** and make one or something.

 

i would buy one like the one higgi made in a HEARTBEAT.

 

shouldnt be too hard to make one like higgis. Best thing would be to start out with a cardboard template. I'd do it but I'm super super lazy.

 

I like the one JasonL has posted, depending on price and what the finished product looks like i'll take one
P.S. my car is an 86 GXL missing whatever tray is supposed to go under there . . .
its about to get really hot out here in AZ

 

No that is part of the 86-87 Sports Aero package, and 88 Turbo and 88 GTU aero package. It is not very common on US models and considerably lowers the aero drag of the car. That rare part is what someone would need to make. It is not uncommon to see that panel go for $50-$100 on ebay as it is very rare.

See that makes no sense to me, as the stock part is as common (in fact more common) than balone slicer wheels. And the last thing we would need is somone making that peice... I mean look at that alum one (that JasonL posted) up above... it has absolutly no aero dynamic help what so ever... it does not even cover what the factory panel covers. And the factory panel can be moulded very easily around any extra intercoolers by just using a heat gun... No that 56-111B replacement would be a waste and certinly not something I would ever consider spending anything more than $15-25 (USD) as that is the average price of one at a junk yard.

 

i want every single undertray panel possible that came on these cars! because currently, like i said i don't have any undertrays what so ever...

 

^^ditto

 

Icemark, I would be more than willing to build the one your are describing, however I would need to see pictures of it, if at all possible... as I not entirely sure as to it's position and mounting, neither it's purpose... if you can source me a pic of it either on the car or not I will see if it will be easily replicated.

 

To be honest, I've never even noticed how 56-11Y (eg. bolt hole locations). Anyone know?

 

its held on by a couple of m6 bolt/washers.......this weekend i should be able to get some pics online...whos able to host them?
