What did you do to your S550 Mustang today?!

[JnBama]

Washed it off this morning , will admire it this afternoon while sitting on my patio enjoying a few cold ones.

I took it to All Aspects Motorsports in Chesapeake. They have 2 dozen Subarus parked out front, so at least my car's color fit in.

I was worried about heat and humidity affecting the power, but once I arrived at the shop the temperature had gone down. The humidity was still ridiculous. I had 93 octane gas in the car, and the humidity was higher than my octane.

My car is a 2020 GT (6-spd manual) and it's stock. 9,140-ish miles on it.
I broke it in as best I could, and wanted to see the results.
TL/DR: 419hp @ 6600rpm, 418 ft-lbs @ 4400rpm (at 71 degrees and 94% humidity)

Once the car was strapped down, they tried to spin the rollers and make sure the engine was warm, and the computer fussed and threw an ABS code. It wasn't happy about having the front tires sit still and the back tires turning. ...So that was a really short pull.

(I wonder if we should have tried the line lock)

We started searching the internet for whether the car had a "dyno mode" we needed to use. One guy found something that prompted him to unplug this thing near the driver's side front strut.

(And for some reason I can't get it to post rightside up.)

The first dyno pull, they tested in 3rd gear, going all the way to redline, and got 388hp.
Right away I was like "That SUCKS"

We decided to try the next pull in 4rd gear, knowing the car could trip the 150mph governor in that gear. Sure enough, the governor shut down the fun at 6600rpm, thinking the car was going naughty speeds. But before 6600rpm, the dyno measured 409hp.

Before the 3rd and final pull, the guys decided to cool the engine bay as much as they could. The display between the gauges showed the cylinder heads getting hot.

The 3rd pull got us 419hp and 418 ft-lbs of torque.

(My scanner isn't hooked up right now. Please excuse the crappy cell phone pic of the dyno printout. At least it's higher resolution than the cell phone video.)

Ford said a 2020 Mustang GT made peak power at 7500rpm and, sure enough, my highest graph line is climbing slightly when the 150mph governor cuts in.

I don't have much to complain about considering I was expecting 405-ish horsepower, hoping for 415, and what I got was 419hp.

Nice…. Hope to get them to my alignment sometime in June

Today I answered the door and picked up my new replacement radio bezel.

Got a puncture mid drive 2 miles away from home was able to park it somewhere before it got flat. Busted out my trusty tire inflator kit for the first time and it promptly burned itself out in less than 5 minutes of use and never got the tire to more than 9psi before it went flat again. Threw it right in the trash can't believe I drove with dead weight for 6 years. Guess I'll have to get creative tomorrow and remedy but I'm done thinking about this anymore today. Walking home now posting on 6G.

Punctures don't happen often, but they do happen ... I have had 3 in the last 10 years or so (well one was a broken valve stem - not a true puncture).

I am glad you posted this because I have been skeptical about the inflator kit. I will probably pull the trigger on one of the spare tire kits soon: https://accessories.ford.com/products/mustang-2015-2020-spare-tire-kit-for-v6-i4-and-gt-coupe-1

Just one more thing Ford seems to be cheaping out on

Oh, I got more mail.

Alignment done. Toe is set to 0.05 in the rear at -1.9 camber and front is -1.8 and 0 toe, but my subframe is off centre so I’ve bought steeda alignment kit and black lug nuts from Steeda Canada. Man I missed having a Mustang.

Did something I’ve always wanted to do today and finally lowered my car. Thanks for working on my car today @bankyf appreciate it!

Hell yeah!!
Looks good.

Welcome back to the money pit, I mean club.

Got the gt500/Mach one swing with gurney flap on… It’s about three pounds lighter (6-7 lbs with flap) than the pp1 spoiler (9-10lbs) The gurney flap absolutely destroys gas mileage on the highway.. Sucks cause it looks so good on there!!

I got a stablemate for my Coyote. I sometimes need more room for dogs & stuff, and want a winter driver, so I ordered a new Lincoln Corsair GT, fully loaded, in January. Same story as some of you Mach 1 hopefuls: four production week delays so far, with no hope things will improve. So I did some online research and hunting, and found a late-model loaded sweetie:

If I'm not hahppy with it, it can be a down-payment tradein for the Corsair if it ever gets built.

 

[Skraight!]

Installed the Mach1 spoiler and SVE wheels as well

could you perhaps quantify?

Just saying ...

Gave her an Adam's waterless wash in the garage. Then went over it with the Zaino Gloss Enhancer, which works hand and hand with the other Zaino polishing items I use.

I hope to take her out tomorrow and on Monday for Memorial Day. God Bless our military,......past and present.

I think he means since it is at such a small angle it creates so much drag and disrupts smooth airflow needed for good gas mileage.
