Dark Horse GT3 Testing

I'm so happy Mustang is entering GT3 racing. This thing is gonna be nuts.

That's fire! They removed the Honda Accord/CRV front of the S650 with better design lines. The taillights also look way better with this iteration. Sounds incredible too.

That 5.4L!
I hope that engine makes it to a street car version at some point. It should if it's homologated.

I hope those massive ducted hood vents make it to a street car as well...or at least the DH S or R

Even Ford can't turn the camera sideways...

It looks like a Frankenstein to me at this point but you gotta start somewhere.

How little positive rake is in the rear wing? The front splitter almost looks like it has negative rake? Plus it's intriguing how far set back the rear diffuser is on this car. I'd like to see the tunnel analysis they did for the rear wing legs of that position vs vertical swan legs. Notice the cutouts in the bottom of the legs they made?

Cool stuff to see.

It does. More noticeable on the 488 GT3.
I'm no aerodynamicist, but from what I understand, you want to get more air going under the car and speed that flow up to create a greater negative pressure region.
Think of the entire underbody of the car as an airfoil shape. The splitter has an upward angle same as the leading edge of a wing and the diffuser would have the same upward angle acting as the trailing edge of the wing.

AJ Hartman on TMO could explain it much better.


Most people take this approach for aero

And real race cars do this

I agree 100%. I've spoke to AJ quite a bit. He told me the best results for the splitter are zero or slightly positive rake. He said negative (meaning front to back) no good. I run my splitter as close to zero as I can get it to help that air get under the car but still have the df I need. Seems weird to run negative but if other aero is generating that much front downforce and the benefits of forcing more air under the car outweigh the losses of a little downforce then numbers don't lie. I suppose if the air is moving that freely and that diffuser does its job than the zeroed out wing with huge side panels is purely for balance more than rear downforce.

Compared to a TA specialty car like RCMs new Gobstopper this GT3 wing looks useless with no rake. But there are also class regulations to consider I'm sure. Also look how zero RCMs front aero is. Bottom line it all comes down to the wind tunnel. But a 900hp 1000kg car with 2 tons of downforce at 160mph is a different animal than a GT3 car.

The entire splitter probably isnt negative rake, just the front of it is. (Its not flat). Seen it on other race cars. Crams more air under there and accelerates it under the hump for a Venturi effect.

For our simpler basically flat splitters, we’re all positive.

That swan neck wing is wicked.

DH-GT3 next year is going to be awesome to watch. DH-R and S out in events as well. Any word what engine will be in the DH-R, S?
5.0 probably maybe 5.4?

Not exactly pretty but i suppose it will look better in a brighter colour . The S650 Australian supercar is looking the goods though

I'm partial to the GT3.

Same 5.4 as in the Supercars though reliability might be a problem:

On my 17 GT stock it started to float the front end around 100 Mph. I lowered the front by 1 inch and the float went away. I think the stock splitter is designed to stop high speed runs by average drivers.

That's the GT4 but I do agree, it is beautiful.
