Pic is day 1 at the dealer as they got my Black Beauty ready for me to gallop home in. She's a '21 Chassis #: M1627. Born on 12/21/21 and one of the last of the '21's.
Specs: 101A, 6 speed, HPP, HP. Looking to see how many fellow HPP owners are active here. Drop a pic (or a few) and tell us why you chose yours? For me it was to get down to one car that I could easily drive year round (although I'll admit the Corsa's are a bit sketchy on cold asphalt). I previously had a '06 V6 as a daily and a '18 GT on E85/longtubes/full Steeda/drag pack. The HPP/HP slit the difference between those 2 Mustangs pretty nicely to give me one car I can drive in any weather safely. And a great way to get back to driving stick since both my '06 and '18 were automatics.

I have a similar spec. 2021 HPP with handling in antimatter blue. Intercooler, downpipe and a tune.

Great car.

Actually just built the motor with forges Pistons and Rods after an unfortunate incident at the track.
I'm assembling pieces for mine. Got the Cobb OTS Stage 1 on the car, CVF street IC and Steeda IRS braces sitting on the garage floor to go on the car next time it warms up. Other minor stuff I've done: Steeda jacking rails, Pedder's poly transmission mount bushing, white shift knob, Steeda clutch spring and cradle. I might do a catted 3" DP next summer, dunno on that. I like the way the active exhaust sounds as is in sport. DP didn't seem to do much on my FoST when I went Stage 3 with that. I might go E30 also if I add a DP like my FoST build.

I have the 2020 shadow black, the HPP has a 52.5 mm turbo?
So is the nx2 an actual upgrade to this other then you can put 19psi waste gate on it?
Even though I had a black t-top 4 cyl 4 manual foxbody back in the 90s, black was not my first choice, but it's what I got at the time I seen a good price for it at carmax in texas and had it shipped to kansas, well worth it, I love it, I was specifically looking for a manual and HPP was second option.

From what I read from others who've switched turbo in our cars, the NX2 would be an upgrade, but you'd also be in need of a fuel delivery system (if you go big) and tuning too. Have you considered doing an intermediate step and just giving a Cobb tuner at try first? I got mine on sale, so shipped cost with tax made it then normal price of $625. The OTS Stage 1 tune I'm running seems very comparable to the pro tunes that Unleashed Tuning put together for me on both my '17 Focus ST and my '18 GT (the 93 octane tunes at least, I also had ethanol tunes for both cars). You'd be surprised how much more torque you can squeeze out of even an HPP on stock turbo. Enough that traction starts become an issue down low. Enough that I'll be putting the Steeda IRS subframe braces that I took off my '18 before selling it on my '21 now. Food for thought...

I'll mention it again, I have Ryan's pro-tune for 91 & E30, my question is about the turbo because the hpp stock turbo is 52.5 mm and the nx2 is 52 mm, with only one other difference that I know of is that the nx2 can be equipped with a 19 psi wastegate, while the stock turbo can only go up to a 14 psi, if I am reading the nx2 specs wrong then please correct me.

Wish I knew enough about the Mustang Ecoboost platform to answer that for ya. Hopefully someone can come along, read this and do so. I notice you've put an ST badge on the rear deck lid of your Mustang. If your question was regarding the ST platform I'd be answer to answer it better. I did a Stage 3 FoST build with methanol right before I got back into Mustangs in March, 2018. Even though it doesn't answer you directly, I have a question for ya...did you ever own an ST also? And did you ever track it? I went to Ford Racing School after the purchase of my '17 (Grantsville, Utah). Had the trip booked before I bought my '18 GT which made me sell my FoST. But it was still a fun trip... Wondering if anyone else here has one of these also? Cheers!

No I've never owned an ST, it is just a joke with one of My buddies with a 2016 foST, I was thinking of putting an RS badge but I felt that it is missing something the RS has.

Chassis L1088 HPP/HP 6MT. Using mostly for autocross now, D street. A ton of fun, well 1.6 tons. You can lighten the car by about 40 pounds with a set of lightweight wheels. View attachment 43801
Did you also gut the interior? Take out back seat? That's another 25 lbs...

No in street class there is no allowance for interior parts removal. just after catalytic converter exhaust, brake pads and fluids, secondary ignition parts, wheels and tires and one sway bar. To go big move to CAM-C where anything goes down to a minimum weight of 3300 pounds I think.
