Anyone regrats their DH purchase?

[roadpilot]

First let me say that my selective snipping of your message is not intended to alter your content but rather to foster a little brevity. While as a powertrain engineer I’m sure your conclusions are correct they seem to ignore the most obvious point, to wit: if you want to go faster, the foot pedal on the far right is designed to take care of that. Trust me, it works just fine. The car does not slow down in a more aggressive mode if you just give it the beans! For the life of me I don’t understand why this is such a difficult concept. I see no need to overthink or overanalyze this. Throttle mapping fools no one when you’re WFO.

Agree. I have zero issues.

I have to say my DH is really growing on me:
Just did my own oil change to full synthetic at 1200mi on Saturday , already did the h-pipe and air intake mods few weeks prior:
Wife and I went to Mother’s Day dinner last night on a perfect 70 degree evening.
Car freakin rips and sounds amazing now!
No Regerts

You have excellent eyesight and are very perceptive. They are 2021 Mach 1 Non-Handling Pack Optional Y Spoke wheels. They were a takeoff from my 2021 Mach 1 which I sold after it was repaired from a bad rear end collision. I mounted Continental Extreme Contact DWS 06 Plus Ultra High-Performance All-Season tires in the standard factory sizes on the 2021 Y spoke wheels.

I kept the factory 2025 DH wheels with their summer Pirelli tires. Yes, I had to switch the TPMS sensors to the 433 MHZ type used on the 2024/2025 cars. Externally, the 2021 TPMS sensors and the 2025 TPMS sensors are exactly alike but the 2025 car cannot read a signal from the 315 MHZ 2021 TPMS sensors. However, other than that, the 2021 Mach 1 wheels are a perfect fit. The 2021 wheels have more gloss than the 2025 wheels.

P.S. When I first got the 2021 Mach 1 in March 2021, I took off the Factory optional Y Spoke wheels with their summer performance tires and mounted All Season tires on a set of factory Mach 1 Base Five spoke wheels which were on the car when I sold it. Therefore, the condition of the 2021 Y spokes were nearly new when I mounted them on the DH.

Have you ever tried putting on either HP wheels/tires on the non-HP M1/DH? Im trying to figure out if there will be any increased wheel gap

I'll keep my reply to the point ...

When i joined this forum (after ordering my car) there was quite a few comments / complaints about the throttle response and how it was sluggish and lazy.
With people recommending 'throttle commanders' that alter the throttle response curve.

This was not my first impression when in normal and sport mode but in slippery mode it was and thats what you want.

When the weather finally warmed up and dried out i thought i'd try track mode to see if that was the spark that had been missing only to find it lazy and lack luster. I certainly did not expect a car to slow down when you put it into a more aggressive mode.

Being an automotive powertrain engineer i ran a few quick experiments and shared what i did on here so others could do similar and contribute.
There was a chance that my car had the wrong throttle map but seems others are having the same experience.

There are many nuances to throttle control on a drive by wire system that is significantly different to mechanical linkage throttles.

There is the throttle curve (including range) where pedal position translates to torque demand.
Sportier modes tend to start lower (more engine braking) and have a steeper ramp initial ramp upto around 90% torque demand and then a gentle tail off for the final section.

This means if someone only half presses the throttle it feels fast, and there is fine control in the last half of the pedal to balance the car.

The other part is the response to step input changes.
Sudden changes in throttle demand are damped in normal modes to make it less jerky, sportier modes reduce this damping and a track mode i'd expect there to be none but it felt more damped not less.

As previously mentioned i used to have a V10 M5, the power / torque curves are actually surprisingly similar it just rev's even higher. I'm not sure if that car had shorter gearing or not but it had far more initial punch to the point you had to brace yourself going full throttle in second else it would throw you back in your seat hard enough that you lift off a little bit of throttle.
That's the sort of adrenaline rush i was hoping for, guess i'll have to supercharge it to find out.

As for M2 no thanks not a fan of the looks but for ref my colleagues M240i that pulls harder / faster than the DH and it has over 100bhp less.

Edit - added the power and torque curves for the 3 cars mentioned, note you really feel that extra 100fb-lb's at 1500rpm

A couple of comments

I think I read that Ford make the track mode throttle map linear for more control so not as aggressive as sport mode. This is deliberate for modulation on the track rather than a 'sporty aggressive' feel.

The power curve you see there is for the European model I assume - it flat lines at 450bhp. For those moaning about European DH cars having less power the only difference is that US cars don't have the flat line and go on up further - but this is only important over 6000rpm, so track use really.

I’ve done a lot of research on this when I had my 21 non-hp Mach 1 . Posted a thread where people sent pics of their wheel gaps and they are noticeable. You have to lower the car to overcome this or it will look bad.
Look at the diameter of the fatter tires the 275/40r19 rears are 27.7 which is big!

I have not tried putting HP wheels on my 2021 non-HP Mach 1 or my 2025 non-HP Dark Horse since I do not have those wheels. The HP wheels are wider than the non-HP wheels. The HP wheels take wider but lower aspect ratio tires: 305/30-19 Front & 315/30-19 Rear. The non-HP wheel tire sizes are: 255/40-19 Front & 275/40-19 Rear.

Tire height off the rim, on one side, is the width times the aspect ratio. So, I estimate that the HP Front wheel/tire overall diameter is approx. 0.83 inch smaller than the non-HP wheel/tire and the HP Rear wheel/tire overall diameter is approx. 1.22 inches smaller than the non-HP wheel/tire.
