2023 Mach 1 -Twins?

I'd run the Hellion Sleeper kit on E85 for your goals. 93 octane is not feasible over 700rwhp. It won't be difficult to trap 145+mph. You'll need a full fuel system and your transmission won't last long at that power level.

It can be done for $25k-$30k if your doing the work. If your paying someone, then you may exceed that budget.

Or, I'll sell you my car that already does what you want for $45k. Lol

Please share what front wheels and tires you ran to trap 145+MPH.

I just had the hellion sleeper kit installed end of summer. 2022 M1 manual transmission. 700 whp on 93 up to 900 whp on e85. A tune for 93 and a tune for E85. The turbo whine is awesome. I havent been to the track yet to turn it up. 30k will do it.

I was looking into doing the sleeper kit for my gt or an ess centri. I was watching videos online. By algorithm luck a video popped up of an ess kit vs tt sleeper both running the same psi. From the tt pov it shows him winning most runs. A few days later the centri guy posts his video of same race & it was only a win by a small margin. So the cost to tt over the ess kit made the centri a bit more appealing to me. The only reason I'd still go tt sleeper is due to the bov & loudness of the centri. I'd rather keep my car as stock sounding as possible do to the wife also driving it. Now where I stopped was when I seen the same tt guy post up his video braking his opg's. So decided to do my opg/cs first then maybe next year go for boost.

Don't let the videos fool you. The hellion kit sounds really mean once the wastegates open!

Hey everyone. I need some knowledge please! Getting back into a Mach 1, this time automatic, which I’m torn on because I love rowing those gears but hey, automatic is faster.

Anyway, I’m definitely going to turbo the Mach. My goals..high 800whp, as little lag as possible, reliable for years to come and be able consistently run top end with the likes of say McLaren 720s or higher. i.e run 145 or higher in a quarter mile span.

Soooo do I go single or twin? If twin, I’m looking at Hellions’ kits. Is there any difference between sleeper kits or top mount kits? I was swaying towards top mount. 62, 64, 68 or from what I saw others mention 55mm BB turbo?

At the power level I'm thinking do I need to upgrade any other part of the car besides fuel? I don’t plan on launching out the whole, this will be my daily so any races will be rolling.

I’m hoping 25/30k is enough to get it all done. FYI I also want mild cams, and H-Pipe with Flowmasters for that old school sounds or at least as close as possible.

Please let me know your thoughts. Hungry for opinions

Thxs!

"High 800 whp and reliable for years to come" = You will need a built transmission, a built short block, a fuel system with E85 (you will never get high 800+ wheel on pump gas, or maybe once and then blow it up) all the suspension mods, wheels and tires, and still probably lose to a bone stock 720s

Yeah I heard a few clips of it. But do you also hear the bov every time you let off the go pedal? Only turbo car I've had was a 95' RX-7 & it was nice & somewhat quiet.

It's quiet on the hellion kit too. I was surprised how quiet the bov is when I first installed it. You'll hear it but it's not a loud whistle like some. The wastegates on the other hand sound like all hell is breaking loose once you get on it. It's a wonderful sound lol.

Agree on all the necessary mods you listed but at that point it "should" keep up with a stock 720. They run low 5s 60-130. If your a10 is high 800s and you aren't pulling at least low 5s something is wrong.

There's just so many things to overcome from a physics standpoint that even with a 850 wheel hp S550, the McLaren is many leagues above the stang. I'd wager that to beat the Mclaren, the Mustang would need 1,000 whp, and that would only apply to 60-130 pulls, and probably a drag race on a prepped surface with the right tires etc. On the street, the Mustang will never win, nor on a road course or proper racetrack.

720s weighs 2,828 lbs (dry weight, so maybe 3000 wet)
720s is far more aerodynamic, with active aero
720s has a better transmission
720s has the motor over the rear wheels
720s has a carbon fiber monocage chassis
Probably a bunch of other details that make it so fast.

Plenty of Stangs on here that are sub 10 second cars, but only in very controlled environments

Sounds like something I would definitely like.

This;

A 720s will be faster stock, on real street tires, on a non-prepared surface. It doesn't need a specifically created environment to accelerate quickly in a straight line, including drag slicks and front skinnies. Plus, a 720s doesn't have to compromise handling and braking in the quest to accelerate quickly in a straight line.

There's just no comparison between a 30K rental platform, and a hand-built $300+K super car. The physics alone are a gigantic difference, let alone all the mechanical differences.

Where did the OP say he wanted a car to compete will all aspects of a 720S? He said he wants to be able to run top end with the likes of a 720S or trap 145mph. A twin turbo Coyote on E85 is capable of doing that.

I don't think anyone expects a Mustang to be in the same super car realm as a 720S as far as all around performance is concerned.

@Ecruz0884 Or, just sell your car and buy this. Job done.

No one.

But in the real world, a 720s will still be faster in a straight line.

And keep in mind, a Mach 1 with the Handling Package with pull almost as much G in a corner, and stop pretty much just as hard & fast. But you'll have to throw that all away to accelerate almost as fast.

It's just a total waste. Mustangs aren't straight-line performance cars. Start with one that is, one that has physics on it's side. Honestly, the OP would be vastly better served getting a used Z51 C8, rather than dropping the same coin on a 2023 M1 and tens of thousands of dollars in mods.
