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

[SOB]

If I do end up getting an FT-86 the only changes I could see myself making would be...

- Exhaust
- Light tint
- Clear bra to prevent debri from chipping my paint!

Short and sweet!

Its all about the looks man. Therefore, it is Race Inspired Cosmetic Enhancement. If you were serious about, say cooling or weight reduction, the hood would be LAST on your list of upgrades.

Are you kidding me? Heat rises, plus air moving through the bottom forces the hot air up anyway, now tell me, what's above the engine? The hood, now let's say your factory hood, is better then most, and dosnt have the thin insulation that some vehicles, that CF that just looks good, will also help to disipate that trapped heat, now make it a vented CF hood and it shows up as power (that is a noticeable diff) on a Dyno, it's been proven. But you know what, don't worry about functionality, just make sure your car looks good, that's your ticket

Rice has to be one of the most overused words in modern history... Rice and down right disgustingly bad tackiness in taste are not the same thing.

I'm getting a chuckle out of the people dissing using carbon fiber in a relevant application. There are plenty of functional carbon components out there that aren't "rice". Anyone want to argue that the carbon tubs for the McLaren MP4-12C and Lamborghini Aventador [not to mention most components on Formula1 cars] aren't legit?

Yeah and I see Rice used all the time but I don't see Corn. Why?

Anyway water cooling > air cooling. If you want more cooling capacity upgrade your radiator .

One of the few tasteful aerodynamic improvements you can make to a car are belly pans. And you could DIY design those for downforce or drag reduction.

Rice is over used, I have to agree. HOWEVER. Who's to determine whether something looks good or not? Because everybody's taste is different. I see ballers with amuse'd s2000s with kits that cost nearly 5k. YET those cars have never seen the track, and have a basically stock engine. To me, that is straight up rice.

And no, an exhaust and intake has much more benefits on a turbo'd engine. As well as distinct sound and better throttle response, they provide better cooling and more weight reduction than any fake CF hood. Id take that over a real hood any day.

@Allch Chcar, I completely agree. There are better ways of achieving said results.

Basically, my point is, rice isn't determined from body modifications looking good, its determined from whether those modifications are actually used, be it for autocross, or for circuit racing.

As for your supra, it is an exception. Notice I said "modern"; by that I mean aluminum.

Ok, but your missing the point, it helps with cooling, your right so does a/m radiators, Elec water pumps, dual Elec fans...ect. But what I'm saying is that even with all that, the hood can still help a great deal, in the persuit of a cooler running engine every little bit helps.

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

Electric fans are pretty much standard now on most cars, not so much trucks .

Electric waterpump/oilpump have been prove to be more fuel efficient than the cheaper/simpler pulley and gear stuff. My example is that the Prius(laugh if you will) eliminated the serpentine belt and switched to an electric water pump and oil pump.

So it might become more common as standards become more strict .

Just another thing to keep in mind...

The vents allow more air through the rad by reducing the pressure in the engine compartment. Same with the bellypan/undertray. Without the vents an undertray won't produce downforce as the pressure acts both against the bottom of the hood and the top of the undertray. Venting lets any high pressure only press against the tray, down.

Chances are, TRD is going to come out with aftermarket shocks/spring set, roll bars, and wheels.

I'll stick to carbotech brake pads, upgraded fluids, maybe lightweight wheels, and proper Direzza Star Specs. None too wide.

I do think all the talk of aero isn't too important unless we're talking about actual track speeds.

Ah a student of aerodynamics I see. But if you vent the high pressure air into the engine bay you will lose pressure on the windshield. Instead you should increase the air flow from the forward direction and angle the belly pan to an angle of attack(similar to an inverted wing) thereby increasing the pressure in the engine bay and reducing any pressure under the pan, am I right? I don't pretend to be an expert, I am just a student of aerodynamics you see.

Aero is a big deal even at regular road speeds. Infact downforce is usually just used in moderation for stability at higher speeds. Where downforce is most used is low speeds, in cars with modest to high HP. The more HP the more downforce you can use without slowing down the car too much that it slows down lap times. For example if you're racing faster than 60mph with very little HP and a lot of straightaways then downforce would just slow you down. That's a very simple way of putting it, but it varies greatly.

Yea its just my opinion. Just not my cup of tea.

Yeah, but I was using the Supra for instance on that one, it comes with the mechanical fan/water pump, but your right on thinking that the FR-S should be electric fans/pump, at least I would think so as well

Nope. Pressure exerts force equally in all directions, so the downforce you gain by pushing down on the undertray is cancelled out by the lift caused by pushing up on the hood. 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.

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.
