- Here's a look at a one-of-a-kind Foxbody built by Roush that very well could have been the 1990 25th Anniversary Mustang, but Ford didn't go for it.

Roush could sell that turbo kit today people would buy it.
Intercooler would be nice
Non intercooled... Meh. Engines don't like hot pressurized air.
It would HAVE to have an intercooler! That thing would have to run lower boost with no ‘cooler
I worked at Roush back in ‘87 and was the mechanic that assembled the vehicle with the initial 351 NA engine and T5 trans along with the suspension package. I also did various updates and actually dislocated my shoulder reaching under the front fascia trying to tie it down on a car hauler for a test trip.
Any idea what the motor was at n/a? Around 230hp/345tq would've been my guess
@@DrBeef216 The engine was just a truck engine with a fabricated upper intake manifold. I don’t believe it ever made it on the Dynamometer.
I'm shocked it doesn't even have subframe connectors, at least from what I saw today at the open house.
Any reason that was never done?
Wasn't it a Mercury 351 out of a boat and I'm assuming that was chosen because boat engines are held to a higher standard when it comes to their rotating assembly being
@jferrell-6667 that's What?I heard it was a 351 marine engine not a truck engine then They told him it wasn't fast enough so they Put in a marine Cham shaft and then they slapped on the twin turbos from the Thunderbird
Ford was irresponsible for not producing this awesome car. Jack was ahead of his time.
Down right negligent.
Ford almost canceled the Mustang back in this timeframe and substituted the Probe! Lol!! Where was Ford’s collective brains back here. Maybe someone was being “Lewinskied” up the corporate ladder.
Ford likes making money not losing it num nuts.
@@springwoodslasher79 classy
I agree with you
This would've put the 93 Cobra R to shame! This is most likely the seed of the 93 Cobra. Keep up the great content brother!
Thanks Jay.
I met Mr. Roush once, it was back in 1984 and I was inquiring to see if he could squeeze 200hp out of my 1979 Notchback Mustang, 2.3L I4, without batting an eye or hesitation he said "Sure Can". Later in the 2000s I went on to work with Ford Service next to the then new Roush Research and Development facility. Man oh man I consider myself Blessed to have had involvement with Roush and Ford's Performance Programs back then. I hold Mr. Roush and Mr. Shelby in the same high esteem.
The most mysterious fox ever produced in my opinion.
Yeah, nobody seems to know what year it even is. Was killed early by lawyers and insurance people. Thanks.
this shit would’ve been 71 hp away from the f40, aka the most powerful 80s car from factory. 400 hp in a non supercar during the 80s did not exist and ford also didn’t make a forced induction mustang til 03 ofc. man at the time this foxbody would’ve taken american muscle to a whole new level and i truly believe it would’ve changed the car world forever if ford had released it. what could’ve and should’ve been….
@@robertelmo7736 VIN shows it as an '87. I snapped a picture of it today at the open house and ran it.
Please ask Jack to take it out for a spin! 👍🏁
I grew up in Dearborn in the 80's & half my friends parents were Ford engineers or designers & we were all motor heads, & had mustangs of nearly every conceivable year & if Ford said it was ridiculous... Think in terms of 450-480HP ... not the mid 300's... I owned a 1990 GT with 225hp and with that GT's weight, it would take another 200+ hp for that car to ever feel "ridiculous"... Jack was most likely knocking on the door of HP that wouldnt be seen for a decade or more & it messed up Fords marketing plan?
Man I just love that you are bringing these historic Ford's back to life in these Videos...
Andy
I second that !
Another gem from the Jack Roush vault. God bless Evan, great content.💪🏼🇺🇸
Thank you.
That car is a beauty.
Funny story.
I was a Chef at a rest here in metro Detroit area. Had a poster of the SA-10 Saleen in my office.
I was converting my GT to that car.
Server comes in kitchen and says "Steve Saleen wants to meet you."
Server told him of my poster.
I go out there, he is with another fella.
Chat a bit about the SA-10. Then Im asked what do you think of the 93 Cobra.
I was like bah, thumbs down 10 horse?, rims and a wing.
Then Steve with a smirk said, "well meet the designer of that car John Coletti ".
Bamboozled.
It was all good, he told me he was limited on what he could do, I get it.
7spoke wheels, no GT side duct, flair on the rear bumper, and that wing...Jack should be credited for most of the 93 inspiration in my book. Did that car ever see publication? I'd live to find out which mag and edition.
I read every Mustang mag back in the day..I never saw this car
I've seen it. I have a recognition guide of the Fox body Mustang which reviews every registered Fox body from 1979 to the 1993 versions. This one was reviewed as only one of a kind. This thing with the 5.8 liter back in 1989 was putting out 400 hp in its day when your average 5.0 was putting out around 225 hp at that time.
I read the mags for years back in the day, it never was published from what I saw either...a later "guide" hardly qualifies as "registered" nor "published"...what guide? Who published the guide? This is like a full on custom...my 95 Saleen w 427 I built would be similar...it is foolishly fast "First on Race Day" kids
@@andrefecteau Fox- Body Mustang Recognition Guide 1979- 1993 By Shreiner, Thomas A. ; Sessler, Peter C
You can Google it.
@@donkeytime1704 I would if I actually cared...the topic is "the car has never been seen" til now, like your book/guide...now back to topic ...really Saleen was the Man back in the day
We took a tour of the Museum back in '05 and someone that worked there told us some info on the car. Can not confirm if the information is true or not, so believe what you want. We were told it was developed as a prototype for a '93 Cobra. The 351 NA didn't make enough to suit Ford to carry the Cobra name. Twin Turbos were added and now it made close to 700hp (crank) and Ford said it made too much. Roush de-tuned it to just under 500hp, but by that time Ford decided to go a different route of track oriented instead of straight line performance. We were later told that the guy giving the tour was Jack's Son-in-Law. But 1 of the rarest cars he showed us was a '67 Mercury Couger Eliminator w/a Boss 429.
69 cougar maybe? The gte had a 427 but not the boss 429. Must have been lots of fun to tour.
That’s Ford for you, always ignoring some of the best prototypes!!!!
My father had his turbocharged 1994 F150 Lightning featured in Super Ford back in the mid 90’s. It’s gt40 351w made 480whp and 645wtq to the tires with 14psi and the right torque converter. It ran mid to high 11’s in the 1/4 mile. I imagine this would have easily made that power. I didn’t know this mustang existed! Thanks for covering all these cool cars Evan!
Evan is in one of the best Candy Stores ever. Might have to send in a search party in a couple weeks. That intake is as cool as it gets. Tiny throttle bodies must wind up quickly. I’d bet it’s over 400hp, probably closer to 450. With that weight it must move, maybe forward after side to side😳
Evan , we need an update on Willis 7.3 Mustang race car! Absence of news almost makes one think it's not reaching potential ?? Surely there has been testing done at the strip ? I'm sure I am one of thousands wondering !!
Yup, Brian made some updates and it’s finally ready for the track. He’s been putting customer engines ahead of his own racing, but it will be on track soon, hopefully this week or next. Thanks for watching.
talk about a Unicorn!!! I did a video and mentioned that car... was a good amount of work to find info on it and even tougher to find pictures of it! Amazing that you actually stood next to it!
Sweeeet, hate the wheels though
That joker would've been the ZR1 killer of that time. 380 horsepower to just be competitive with that ZR1 Corvette in it's day. I truly believe it.
If you want a really interesting fox body story. And I'm not gonna give you the answer. You gotta find out for yourself because it's that good. But find out why the Ford Motor Company never put a 351w in a fox body mustang from the factory. Even though they did have it in the works at one time. Find out Why it got shut down.
But Ford is responsible for not selling a lot more vehicles given the advice from people like Jack Roush and Carroll Shelby, great Americans
Evan, I am SO STOKED that you did a video on this car, and that it's still alive and well in the Roush Collection!! It is definitely not an '89, I can promise you that. I was living/working in Michigan in 1987, between May and December. Every morning I'd make my daily commute from Royal Oak to Livonia, where our NPD location was literally right down the road, deeper within the industrial area, from Roush's facility (across the street from the Ford transmission plant). On more than one occassion (3 or 4 actually), Roush developers, or hell it might have been Jack himself, were out on Amrhein Road absolutely TEARING it up.. And that car was the fastest thing I'd ever seen on the street. Came around me one morning when I wasn't paying attention, full-throttle 2-lane pass. Anyhow, that was in mid-1987. And yep, the car was just "too wild" (and probably too expensive to build) for production. Rick Schmidt, NPD
Rick, thanks for the insight, much appreciated. Let's plan another day at NPD filming some cars!
I didn't know NPD used to be off Plymouth road! When did it move to Canton?
This car was awesome no doubt about it, but it did not have to be a twin turbo 351. It could have been a completely stock 5.0L HO with an intercooled single turbo. That combination would have been a little easier to package, and more importantly, a little more palatable to Ford. Even back then 350HP would have been attainable with a single turbo. Even at 300HP the torque a stock engine would have made with a single turbo would have made it a monster for that era. It would have packaged well with a T-5 and 3.08 gears and nothing else. What killed this project was the nightmares for Engineers had about dealership service departments pilled to the ceiling with obliterated clutches and T-5 graveyards for as far as the eye could see. What I would have given to rolled up along side a Grand National in a black GT with a factory installed, turbocharged 5.0L and let him go a little ways, then walk him down without speed shifting.
EXACTLY! Ford would not spend that kind of money. They threw a turbo on the 2.3 & people bought it & it now has a cult following. They should have just done the same exact thing with the existing 5.0 (probably even the same exact turbo), nothing but a turbo! (And let the money roll in.)
Heck I would have been happy with a 351 fox body, much less the twin turbos.
An interesting piece of Mustang and Roush history. Would certainly love a video of it running!
Awesome fast Mustang GT 351 twin turbo🔥🚀
Irresponsible? And now we can get a 702 HP pickup truck 🛻
But it's got lane keep assist and Attention Deficit monitoring, so it's totally safe even with 700HP 🤣
I remember this car from the magazines around 30 years ago. I believe it was rated at 400 HP back then. I thought it was amazing. Years later I put a Hellion 62mm kit on my basically stock 5.0 and it made 444.6 HP and 537.8 lb/ft of torque to the wheels. Now we see some production cars making 400+ HP to over 700 straight off the showroom. Who would have ever thought that back then?
Weve got cars making crazy horsepower yes, but they are heavier than ever as well. Kind of defeats the purpose..
@@LegionGamingTV Not Foxes with Coyote swaps. Super light, great power and drivability.
@@johnhickman106 A 351C with a cam and intake makes more power than a Coyote swap and doesnt need a K-Member or brake booster change.. And has great driveability.. Dont see the need for a $4000+ Coyote swap when you can have more horsepower for less money lol.. Actually a 5.0 crate motor is $8k with harness.. Thats stupid lol
@@LegionGamingTV I wasn't arguing. You were talking about the weight of modern cars. I have a built 351C that's sitting at 406 Cid and look forward to putting it in one of my Foxes.
@@johnhickman106 I wasnt either. It just makes no sense to spend that kind of cash on a 5.0 swap when you can get more performance for less cash. Im currently building a 351C .30 over with roller conversion and using TrickFlows EFI Lower and Upper Intakes. Im just stuck on what ECU to run
I wish Ford would have dropped a Windsor in the fox for the '93 Cobra. Even a N/A would have been awesome.
Thanks for covering this, I remember this car from back then
This is amazing. Such a shame that Ford didn't produce it. Even irresponsible, if you will.
And yeah, the 93' Cobra may have looked like it, but it damn sure didn't have the horsepower lol
Roush should have it dynoed. I'd love to know what it put down. And that would have been SO easy to modify lol
400 hp ? on a bad day ?
It was Irresponsible to not start it up!!!!! Such as TEASE! Dyno session??????
Twin turbo’d 5.8 liter engine in a cobra like fox body - sounds very familiar to me… I think he was onto something!
That red is sexy. I miss my 1990 LX Notchback. Was that same color red.
This is another one that was like wtf are you guys doing? Who is saying no and yea to these mustangs being in the wild..... 🗣🗣
Ford always seemed to miss the boat on some of these offerings. Just like now, they push the price points up by squeezing the Bullet in between the GT and the GT500. Why not offer a twin turbo (turbos off of the ecoboost lineup) in a stripped down fully forged coyote), and call it a LX, that could go against the 392 Hemi Challengers ? Sell it for $40k with a T56/magnum or 10 spd. Keep the marketing people out of it and allow true ala cart options without being stuck in a $7000 upgrade just to get the better braking, and a 19" wheel.
Also has Jack put a twin turbo on a a current Gen Coyote ? Just curious as to the power. Thanks
Cobra R. The wheels turbo all scream jdm inspired lol for the times.
I want to see this thing do a full pull. Like here if you want to see this thing hall ass

Man I'd really like to have that front bumper
I know right! I've been searching everywhere for one that looks similar. Do you know if there are any like it for sale, or was the bumper custom made?
WOW WOW VERY MYSTERIOUS FOX JUST BEEN SITTIN THERE THIS WHOLE TIME AND NOBODY KNEW IT EXHIST
It has vert/ttop style mirrors on it that is really cool. The lower grill was much wider I assume to feed more air to the intercooler man this thing was waaayyy ahead of its time. This thing would have been a torque monster and a modders dream. You could throw a cowl hood on it with a taller better flowing intake (I imagine there may have been aftermarket versions of this dual intake setup had it seen production) and up the boost or do turbo swap and you could have ungodly power. Even the stock power would have been mind blowing at that time. Way way ahead of its time much like the Calloway vettes but they weren't really production vehicles per se. They were modified after the fact like saleen mustangs etc. I guess this roush would have been similar in that regaurd. these are very cool. The black cheese graders made the tails look tinted which gives them a modern style and it does look like the 93 cobra got alot of styling from this car. The black cheese graders were kind of like the black saleen tails in the sn95 era but this was well before that. Super cool innovative car and it's a shame it never seen production shame on you ford.
Said it's non intercooled
Revin Evan, thank you for bringing us all this good insight and memories! Does anyone remember a black 1987 GT that had the front slats all the way across the bottom opening of the bumper cover? It was a car that was in the Ford brochure back then. I bought my 1st brand new Mustang GT January 06, 1987 at Carl Flammer Ford Tarpon Springs... Florida
Dan, you’re welcome!
Coolest shit ever shit fuck dammmnn
If only Ford had built it... thanks Evan!
Maybe the year discrepancy thing had to do with the amount of time it took to build the car. It is feasible that he started on the 25th anniversary car a couple of years in advance. Especially since it had to be revised from n/a to twin turbo.
Start it already!
Interesting that this prototype Mustang has the T-Top/convertible style of flag door mirrors yet is a solid roof hatchback. I vividly remember this car being in the Mustang oriented magazines of the era, it looked cobbled together then, as it does now. I'm pretty sure the HP numbers touted way back then were 400ish.
Good eye!
I actually drove that car, I was working as a process engineer at the Dearborn Assembly Plant and they brought it over for us to look at it to see what it would take to build it if it was approved. The truck drive pulled if off the carrier and I drove it to the plant. Man what a car. It was fantastic for the day, loved it.
Also the 98 Super Stallion..🥴
Non intercooled!! Talk about heat soak
Ford 100 percent copied the look for the Cobra
twin turbo twin throttle body.. this was a head of its time
Appreciate all your uploads. Sick Fox
Thank you!
Whats up with that silver Magnum?
This was made to go against the 405hp vette at the time!!
Very unique. And i can see the styling cues from the cobra.
Tell the truth evan - those rims absolutely suck. You wont piss jack off tell the truth
Awful!
Another great video E👍
Man that is one BA Stang, I'd love to have a 351 in mine today to boost. So much more to work with.
Thanks!
Legendary status. Mustang history is amazing 👏.
Twin chargers on a bone stock 351 is deep into 550bhp at 7 psi. I believe you are way way off on what kinda number that package was capable of, even not intercooled. I mean the Buick Gn was what 285 on a super small single and about 125 less cubic inches an 2 less jugs
Too cool! I’d imagine that would have been pretty radical back then…
From what I can gather, there's a multitude of reasons it never made it
One was Ford crying too powerful (wussies!)
Two was the T5 would just shatter (They planned to use a T56 but they weren't available yet when they built this car)
Three was apparently even with all of SVO's tricks, the chassis couldn't handle it. I'm not so sure about that- the car doesn't have subframe connectors, no strut braces, nothing that I could see when I looked it over today.
The last two points were stated by Mark Kovalsky in an article for Mustang Source.
I'm kinda wondering why they didn't just use a single turbo and meet Ford in the middle.
Definitely ahead of it's time!
Sweet secret concept. Hey Evan you should get a feature on Racin Jason's ragtop before it goes missing. I'd love to see that again, last time must have been mid 90's J&P Performance shootout. It would be a great history video for any younger folks
Pretty sure I saw & heard that car in Yucca, Az at proving grounds headed for the track. Does it have straight exhaust no mufflers?
They would not let me look underhood and all they would say was twin turbo & it was fast.
If this car was never in Yucca then there was a twin. They gave us a ride in a 15 passenger van that pulled like freight train with 15 people on it 110+ mph. Again wouldn’t let me see engine but hints were a v-10 with turbos or supercharger. Got the full tour that day!
Saleen pretty much did! Roush's are nothing but cheap Saleen knockoffs
I bet that’s a wild ride.. 351w twin turbo fox with a few mods I’m sure 500hp is there.. I would bet it’s high 11-low 12 second factory car in 1989.. I guess ford didn’t want to be showed up by roush back then.. but that would of been the fastest American made vehicle until the 04 terminator
I think Jack missed the point in his build. If he wanted the Ford engineers on the hook, the tune brief should have been "car to leave hard off the line, minimal wheelspin, extreme mid range, great fuel economy, smoke the competition" Ford puts it into production and when we get it, the brief goes out the window. Pretty much what Ford Australia did with the barra turbo platform.
this shit would’ve and should’ve actually changed the car world forever. this thing was near the ferrari f40 power wise, aka the most powerful factory car from the 80s. im genuinely pissed as a foxbody fan that ford and roush didn’t release this to the public.
edit: forgot to mention that 400 hp from factory in the 80s in a non supercar did not exist at all. and also remember it wasn’t til 2003 that ford introduced a forced induction car from factory, so if they would’ve released a forced induction mustang in the 80s. man what couldve been….
7 lbs boost 450 hp easy. Ford didn’t even have a mustang 351 till 1995
The 71' Boss would disagree with you.
Uh.. lol.
Did he say a truck 351 with twin turbos is only pushing around 400 hp? Maybe with a single turbo with low boost but not twin turbo. Probly closer to 500-600.
That's soooo soooo cool evan
Never seen no shit like that
Amazing. More Evan more if stuff like this! F'n love it
Thank you.
I have a mustang card(aka baseball card) of this car. On the back it says it could mid 12's in the quarter. Imagine what it could run with a set of slicks and some gears.
I asked and you posted this, Thank You Sir for this piece of Foxbody History!!
Marine 351 with a Marine camshaft! They were shooting at the Corvette ZR1 with this piece
Wow that was radical back in the day, your right i think the engineers took some of Jack Rouse ideas and put the into the 93 cobra.
I remember reading that it was faster than the zr1 but the power twisted the door pillars? Maybe that is why production never happened?
Could add a nicer intake cam and some nice heads that are finished and hit 800-1000hp with that if that was the oem fox lord what we coulda done with that setup
That motor actually twisted the body and there is photos and videos showing the tweaks the motor caused on this unibody.
The front clip that should have been on every GT from factory
I wanna see how they fit all that in there. Were there no pictures taken during assembly? I mean it's right there, and no one has any information any further than what you can see from the top of the engine bay?
It's a bummer they wont showcase these type of cars on the track these days because they are too valuable, would love to see this car in action! Hear it at least
a lot of interesting stuff on there, especially the power steering reservoir and the master cylinder. As well as the IAC on one side
I remember seeing these in the car magazines when Ford was mulling over bringing these out.
I remember hearing of this car and was so hopeful. Love the videos!
Wow awesome car! First thought was 93 cobra as well.
At 100 th the engineer telling stories running down Woodward those were good ones
Gorgeous!!! Go in business and sale these!! Also how much
Would have loved to of heard this run. Great fox body.
Where can I find that spoiler/ wing?
Would love to hear it sound of the mustang that paint job looks great
That's not a truck Engine that's a marine engine
Please God take the belt driven fan off. Even to make a statement take it off
It would be torquey and fast.
Does anyone else think that is one restrictive intake?
That t5 was way underrated for that power
