2019 GT350 Upgrades: Tech, Aerodynamics and Other GT500 Track Improvements

[Darkane]

They all neck down to meet with the factory pipes prior to the X-section anyway. And if you want to nit pick, the Borla 2.75" system, for example, is smaller than factory in some spots.

But the bottle necks in the factory system are the smallest. Do you agree they you gained power with yours?

Ford could have done something similar without affecting emissions if there is a legitimate gain.

I do agree that the factory system is ripe with decreased diameter sections that aftermarket systems don't have. I did learn that sometimes there is an acoustical reason for these types of diameter changes (drone reduction, etc) as much as some are there for practical production limitations. I cannot speak to the percentage gain in the Borla system purely on better flowing tubing/bands vs the gain from the mufflers alone.


Ford could have done something, I agree. I'm sure it was a balancing act and something else won out this time around.

I wanted to go back to this one for a moment...

The GT4 Mustang is a professional series race car, where decisions aren't made based on driver enjoyment.

Oddly enough, driver enjoyment may just be a welcome byproduct of the change in these cars. Listen carefully to what Scott Maxwell says at the 41 second mark...

I’ve always pondered on that x-pipe robbing you of power... but I wonder if it also helps promote cracks and pops?:shrug:

In layman's terms...

Yes, an "X" pipe allows wavelengths to harmonize intact, & crossover freely intact. Promoting rasps & resonance.

An "H" pipe allows exhaust gases to equalize, but doesn't allow the sound wavelengths to harmonize or crossover intact. Innately countering rasp & harmonic resonance. It also offers a "doppler effect" to the exhaust note.

Who knows.. maybe they did something with the exhaust.. maybe the GT350 gets the R exhaust w/o resonators.... /wishfulthinking....

Anybody hear anything about Ingot Silver?

I was really disappointed to see that it isn't mentioned in the press release. It's probably the one thing that would get me to trade my OW 2017 for a 2019 someday.

The original promo materials for the GT350 back in 2014 featured an Ingot Silver car, and man alive is it pretty:

I am not sure I buy the part that the R carries over completely unchanged. It if that is true I am not sure what Ford is thinking here.

I think it would be reasonable to infer that the other changes the GT350 is tracking in 2019 would be applied to the R, and possibly even improved on (e.g. R specific shock calibration).

I think most of the performance changes were taken from the R. My bet is some of the weight reduction the 500 is getting will be applied to the R to set it apart from the base 350.

 

[Epiphany]

And I'll bet you the R doesn't get any of that.

You probably right, I have no inside info. Just speculating

 

[fpa1974]

And I'll bet you the R doesn't get any of that.

I hope you are wrong by that I mean that now I am expecting a retune of the suspension, steering and some interior upgrades. Anything else would be a bonus.

See my earlier post with Billy Johnson's comments about the tires.

The new GT350 PSC2 tires are not equivalent to the GT350R PSC2 tires. So the GT350R should still be the king of the track, based on the rubber under the car, downforce and weight savings.

ETA: on top of the R being very limited in production. There will probably end up being less than 2500 of them ever made, I would think.

 

[likeaboss]

The GT350R is still faster than the 19 non-R GT350 around the track...but the "because R" value prop isn't as good anymore now that the gap has been narrowed. Unless you're keeping your car bone stock, I don't see the value of having an R unless you're a collector. Otherwise save the coin and buy the non-R.
