2000HP Toyota Supra Wind Tunnel Aero Testing - The Results were AWESOME!

How effective is aero on a drag car at 200mph? Does aero make that big of a difference? On this episode we go on a journey with Jay Meagher from Real Street Performance to do wind tunnel aero testing on their 2000HP Toyota Supra. The streetable Toyota Supra has been 6.77@210mph in the 1/4 mile, but based on Jay's analysis of the ECU logs from the pass it seems they might be able to find gains from tweaking the aero on the car, so he decided to get some hard facts using the wind tunnel to test what the car is doing at speeds over 150mph. Watch along to find out!

Some people think that the only solution to going faster is adding hp. I appreciate you guys shinning light on the importance of working on the aero as well.

[@fredygump5578]

Cleetus came here, learned how bad Leroy's aero realy is...and changed literally nothing.

[@dj4monie]

Cletus put his Vette Kart in the same wind tunnel.... So what's he done? Instead of putting the Corvette body back on the car he's tried to generate more power with new turbos and 3rd Texas speed long block.... Go figure.

[@Laminur]

He knows the aero is terrible. He made some small changes after being in the wind tunnel without taking away from what Leroy is. If you keep up with his channel he has hinted at some body panels coming to Leroy in the future.

[@ChargedTTq]

Yeah but unless you have atrocious aero and a ton of HP like Leroy, you're only looking at some really minor gains for 1/4 mile stuff. 1/2 mile, standing mile, and roll racing it'll make a bigger difference.

[@aarons2613]

Well there’s 2 ways to make a car faster at high speeds more hp to push threw the drag or better aero dynamics to reduce drag

How cool is that? 40+HP less required to do 200MPH AND effectively 500+ lbs of extra downforce. Shows how much power was being wasted creating undesirable lift. There's no way this won't make a significant difference. It will be far more profound than just adding 50HP.

[@bigreddaman5988]

Exactly, he added far more than 50 hp because he wasn't putting a lot of it down to the ground at high speeds

[@lianpangilinan7583]

Very cool video. Always good to see information on things we don't usually think about.

[@ssoffshore5111]

You should have tested with the nose lifted slightly and the back depressed a little to better replicate it's attitude going down the track under full throttle. Results would have been even worse than what you found...

[@FastPaull]

These were my thoughts exactly. However. What they learned even at a parked attitude, that will translate to gains going down the track.

[@realstreetperformance]

SS OFFSHORE most people would think the same way you did here but unfortunately it’s incorrect. If you watch the videos of this car (or review the shock position sensor for the rear during a pass) it actually lifts the back and down the track higher than its static resting position. It’s a characteristic of the 4 link rear suspension. It does not squat like an IRS car. The rear of the car was set to the ride hight it goes down the track at while it was in the wind tunnel to get accurate info. Thanks for watching. We will continue to bring more new stuff like this moving forward.

[@spooler7828]

Interesting results. Doing 1/2 mile runs I tried a few things. None of it worked properly. I need to spend some time in a wind tunnel to see what is going on. The nose of my car lifts way up in the air. I have a feeling that the hood vents I installed are hurting me big time at 140mph and up.

[@wvupharmd]

I was hoping to see other aero parts in the science experiment. Adding a rear diffuser...OEM wing...TRD/RMM wing...front splitter...what the combo does.... Will you be going back to test more?

[@paulstandeven8572]

I would expect a drop in drag if the nose of the car was dropped a bit, or extending the front air dam downwards. This is to reduce the amount of air going under the car.

[@dj4monie]

So you want free wind tunnel testing on the parts you're most interested in? Why don't you just ask Jay to give you money????

Is the bottom of the car sealed off? Also A carbon rear diffuser would help alot just to get all the air out quickly. But sealing off the entire car will increase downforce and reduce drag alot.

A very good addition to that car would be underbody pannels with a good rear diffuser. Very good for drag coefficient and overall downforce.

When some cars accelerate, they change their gate. My big brother had a Cadillac that would lower in the front and raise a little in the back when you mashed the gas. I wonder if they had the car on rollers and someone actually in the car driving, would they get a different result?

[@hectorn.6137]

i thought aero made a difference, but the amount of difference those small mods and adjustments made was pretty incredible.

[@enquiriesroadtrack4014]

[@handleymacdonald5760]

Wouldn’t holes in the hood help like the fins on some cars help to extract dirty air out of the engine bay?

[@nzsaltflatsracer8054]

Aero is mostly overlooked by the door car guys but it sure makes a bid difference down at the deep end. I added over 50 mph to a Flathead Ford powered car at Bonneville for a guy with body changes within the class rules & he needed to up the gear ratio a few times to keep up. How's 229 mph with a Flathead roadster sound?

[@gtgodbear6320]

They need to set up a Dyno 8n the tunnel. I bet they can get a lot of more turbulence information with the rotating wheels. You can even help wheel design . A propeller spoke design will blow air out cooling the brake system as you're driving. The wheels will be a fan blowing out (or in) at all four corners might be a good design to look into. It could be a bad designed too because it might vacuum up rocks and dirt through your brake system at high speeds.

[@MORC]

I’m not surprised Jay got a science boner over wind tunnel testing. Great content, I love Real Street and always want to see how they make their cars better.

[@michaelovitch]

This study lacks the hot air dumped under the car and hot exhaust gases on top of it on one side. Hot air and gas have way lower density,and reduce pressure where they travel against. You will increase down force again with warm air traveling under the car,but also reduce down force with hot gases traveling on the roof top. You should dump hot gases under the car,and get a diffuser behind the car = less drag,more down force. Caps on the whells will help quite a lot too.

[@aRRakiri]

hello from France, great video though, CX is so important as such speeds !

[@sandragerjanvanboggelen1275]

Good idea to do !!!!! And what a result on hp and downforce

[@pottnah6152]

Wheel covers ..remove mirrors...all the small gains add up...maybe even a proped up hood possibly or window vents ....shit what do I know lol

[@_Bonez12]

Would've been interesting to see what a stock twin turbo wing would do at 200+. Also I'm sure you all considered a vented hood to fix the drag from engine bay air.

[@negativeindustrial]

Kyle B TRD did. Tho their placement is curious. My ST-205 has it’s hood vents in far more useful places.

[@GianniAdduci]

[@Shoultes]

[@EreksonJ]

Does having the motor running WOT affect aero with the turbo pulling air and exhaust dumping out the hood? How about turbulence from the wheels spinning?

[@abhishekkushwaha2455]

That's what i thought. And why they are measuring lift and drag in HP.

Soo sick I would’ve there’s anyway that the air tunnel would work for my 1/8 sale GT Rc car

[@SuperBobKing]

Looking at the video I don't think the sensors for forces would be able to work with something that small. Small scale wind tunnels do exist because the cost goes up exponentially with size, but I have never looked into whether any are publicly available. One that small you could probably DIY. Changing size but keeping the shape the same can be adjusted for mathematically like they were doing with wind speed in the video, so if the body you use is also made at a smaller size you could do that and make an even smaller wind tunnel.

[@modelnutty6503]

SuperBobKing excellent idea, it'd need an air velocimeter to know how fast a fan is pushing/pulling, then 2 or 4 digital scales to see what down/up forces start happening. a couple 20" box fans with stronger motors is probably enough, 10-12ft long with some vanes to keep the flow straight.

[@dj4monie]

It is stock... What's modified????

[@CarsnStuff]

What i meant by that was a completely stock supra. ie stock suspension, ride height, no changed aero or blocked vents and with the wing. I know the wingless is less drag but it would be cool to see both in a wind tunnel just to see the difference in numbers. in general yess the car looks to be an entirely stock body car. But there are factors like ride height and if they have added any sort of panels under the car to aid in aero at higher speeds. thats why im just saying it would be cool to see a 100% supra roll into a wind tunnel and see how the car is. maybe even for fun have it do a wind tunnel test compared to the MKV.
