Who has future plans to molest their FT-86? (examples inside)

[dominican]

The only things I'll be doing is debadging it, add some larger, tasteful rims, preferably with some lip (maybe some LMs), removing cruise control (if that's possible), making the exhaust as big, light, and without restrictions as possible (no inspections in FL, FTMFW), maybe an intake, and most importantly, dropping it like it's hot.

[#87]

I'm not going to agree disagree with the people in this thread, but I think it is HILARIOUS that some of you care SOOO much what other people put on their cars.

To me, if it looks bad then it will just make my car look even better.
If it's not functional, who cares it isn't your money.
If it is useless or whatever, you should be happy people are buying parts and expanding the market for after market parts.

IMO you can say it looks bad, call it rice, or whatever but I don't think it is worth the time to argue about it beyond that. It's just like complaining about other people's driving, it is lose lose all the time every time.

It won't be. With a drive-by-wire throttle the cruise control is handled by software. Other than a few buttons near the steering wheel there's nothing to remove.

Probably go JDM badges to get rid of the Scion stuff. Intake/Exhaust/Flash for some tone and performance bump. Maybe a nice set of wheels. Long shot, if I got it in white, I'd get the roof, pillars, and rear decklid done in gloss black.

It's my DD, so I'm not too concerned with it, but I'm sure eventually I won't be able to help myself. Probably put more money into the suspension than anything though.

To each their own though with that crazy stuff. I did it at one time with my celica, and I loved it's look. People thought it was stock like that because it meshed so well together, outside of the paintjob I had on it which obviously stood out being a real Kandy 3-stage finish.

But your entitled to your own opinion, so what ever floats your boat

if heat is that much of an issue i bet that large sum of money could be better used for bigger injectors a better tune or running e85. thats all im saying.

if i actually get one of these, ill probably drive for a while to see what it needs. ill probalby just end up with wheels tires and suspension components maybe brakes too

Main purpose of the undertray is to smoothly connect the under car air (normally high pressure) to the rear low pressure area to balance them out. With the help of a diffuser of course. A smooth, flat floor with a raked ride height can have a similar but not quite as effective effect.

Airdam's job is to reduce the amount of air getting under the car. And the often-attached splitter's job is to take advantage of the frontal high pressure zone by giving it something that it can push down against.

Is it just me, or (given the understanding that Scion Corporate admitted to be reading the forums) does the ridiculous Mk3 diffuser seem like it's a joke on us, and everyone that was asking to see a diffuser-delete 'chop on the Mk2 Concept?

Are you sure about that? Downforce is proportional to velocity squared. Most vehicles won't see any real downforce until 70+. And if you want anything worthwhile below that you need to go to some pretty extreme lengths. Take a look at a few winged FSAE or SCCA A-mod cars and you'll see what I mean.

Exactly. Usually for road cars, minimizing lift and adding minute downforce is enough, but not adding extreme amounts. It's unnecessary to decrease mpg due to aero drag and increase tire wear for the masses.

You would need to lower the pressure under the undertray. The much easier alternative is to just run a splitter, and let that high pressure region in front of the radiator do the work for you.

You'd need to increase the surface area of the wings to get more downforce at slow speeds. Hence why small spoilers/wings are laughable, they don't make that many lbs of downforce until high speeds.

E85 wouldn't solve a heating problem. It does burn cooler but that isn't quite what we're talking about. The number one issue for overheating is usually with the radiator or coolant not the fuel or anything else. If you make enough HP that the cooling system can't keep up you'll need a larger capacity radiator.

...

Cool, but I mispoke about flowing air into the engine bay what I ment to say is to block the air flow into the engine bay except what is necessary for cooling, the rest just becomes stagnant hot air. What you're saying is eliminate the pressure on the hood/windshield and move the pressure to the belly pan. If the pressure on the hood is greater than the pressure in the bay and the air under the pan than it will exert downforce but probably not as much as what you are saying. So I do kind of understand what you're saying now.

Exactly like high speed cars should be. Minute amounts of downforce for stability and as slippery as possible.

Most of my understanding of aerodynamics is from being interested in decreasing drag from aerodynamics for the most efficiency and MPG. So I don't have much info on the various downforce methods other than knowing what they are eg. canards, airdams, wings, spoilers, etc. Thanks for being kind to me .

you say: "that car is so rice"
I say: "man that car looks shitty"

not directed at anyone, but lets just get rid of that stupid term.. a car either looks good or it doesnt

I usually say "Damn that car looks SICK. I wonder how fast it doesn't go..."

Yes and no. More surface area will make more downforce given an equal coefficient of lift. However, the longer the chord of your airfoils the lower their Reynolds number will be at any given speed, and the lower your Reynold's number is the harder it is to generate downforce. The larger your airfoil is the faster it needs to go to be efficient. On top of that, it will tolerate less angle of attack before stalling for any given speed, and angle of attack is where the vast majority of the downforce comes from. So pure size is a pretty poor investment for low speed downforce.

What you need for low speeds is a wing that can operate at a very high angle of attack, like 20+ degrees (45+ if you're really serious). Any single element wing is just going to be a parachute at that sort of angle, you'll get some downforce along with massive amounts of drag. The trick is to use a multi-element wing, like the two element in F1 but more-so. The second, third etc. airfoils act exactly like the flaps on an airplane, they allow the wing to operate at slower speeds and higher angles of attack without stalling. That's why you'll occasionally see crazy stuff like 4-element wings with leading edge extensions on autocross or hillclimb cars. They look a bit ridiculous, but they will make a couple hundred pounds of downforce at 30 mph.

But yeah small wings are silly. Go big or go home.
Unfortunately, big wings are for race cars and ricers, so wingless it is.

RICE = Race Inspired Cosmetic Enhancements

All the bits that look racy but actually make you slower.

Mine.. will probably look somewhat ricy.. but I plan on getting it tuned once I get a better feel. Lol

Hey that's crazy about the multi-wings. I didn't know that.

Some cars look out of place without at least a spoiler. A small duckbill spoiler is nice touch though, not too big or anything just as an accent .
