2020+ GT500 Engine

[dschmid4]

The 5.2L supercharged intercooled engine (M-6007-M52SC) is available as a crate engine from Ford Performance. I fully understand how insane this would be in a MK4, but does anyone know of a build thread or pictures showing how this would fit? I'm new to these forums and have tried some searches but came up empty.

I think it's a great idea, still possibly insane, but way cool.

But... You'll have to learn to drive it. Serious throttle, i.e. foot and brain connections will be required. You could (I would) restrict the throttle opening while learning to drive the power and then keep adding more as you acclimate.

Probably no way to get it to hookup, there won't be tires that will fit for the necessary traction.

That's close to what the Super Snakes that Shelby built put out. Originally there were two until one went over a cliff.

[JohnK]

The Super Snake story is pretty crazy. Carroll originally only intended to build one for himself. Bill Cosby eventually convinced him to build a second one for him. Cosby drove it once and it scared the $%&* out of him and he sold it back to Carroll, who then sold it to another guy who killed himself in it.

I've not seen any builds with that engine. Not surprising. It's relatively new (last couple years) plus crazy expensive. It's based on the Coyote architecture. So basically should fit in a Roadster. Although I'd be concerned about the height of the supercharger. That much horsepower in one of these cars kind of pointless IMO. Unless you're going drag slicks or something else really sticky, it will be traction limited. Aside from the safety factory. Good show car bragging rights though.

Edit: I forgot about the one that Factory Five had built. That was done by a pro shop and sits in their showroom. Made it to SEMA too.

Soon, I hope, Lynn will have his carb and complete his procharger install. The dyno is waiting.

Rough estimate is 700 RWHP. Should be comparable to the GT500 combo.

I think one of the demo cars at FFR has the 5.2 engine in it, check it out. I think Dave did some parking lot painting with it.

I think one of our past fellow builders put a Coyote with a super charger in his roadster. It was a beautiful and powerful car.
I saw a pic of it wrecked. Seems like it knocked the engine out, hit some palm trees in the median, somewhere in Calif.
He did not survive.
You really have to read the Cobra rules everyday, more so with that kind of HP.

[Jeff Kleiner]

David Williamson and Railroad are both correct.

Here's a carbon fiber Cobra with an 800 HP supercharged Coyote. All tube frame with full independent rocker arm suspension.

FFR has already done this: https://www.factoryfive.com/whats-new/750-hp-predator-powered-factory-five-mk4/

From a quote in the first Jurassic Park movie; "just because you can doesn't mean you should." Yes, Saul from the San Diego area wrapped his supercharged Coyote powered Mk4 around a tree in a median. To say the least, he and the car did not survive. When our cars bite, they can be deadly. While big HP sounds cool and makes for great bragging rights, big supercharged HP in a 2300 lb. car does not make for a satisfying drive. Dave Smith in the intro of one of the MK4 build manuals discussed having 300 HP to be a sweet spot in these cars. Fast enough to be entertaining but controllable. The intro was written more than 10 years ago and things have changed. I would suggest most are going to consider the sweet spot to be between 400 to 500 crank HP. This is why the Coyote has been such a often used engine.
I don't want to sound too much like I am lecturing, but too much torque and HP makes these cars too sensitive to the go pedal. Professional drivers can do more but for most of us, we do not have those kinds of skills or experience.
It will be your car, but other owners have built big block or supercharged cars with high torque and HP that are too scary to drive without constantly being on edge.
Chose, but chose wisely and enjoy your toy.

settle for nothing less than 1200hp, and a HUGE life insurance policy

[dschmid4]

Super good advice all....thank you. I searched a lot more outside of this thread and while there are many 600+HP builds, it's pretty clear to me now this would not be too enjoyable for what I would do with it. I am only ~1 week into exploring these kits (and drooling) and I'll certainly be doing a lot more learning before pulling the trigger. I appreciate your responses and sound advice.

[Alan_C]

If a 3rd Gen Coyote is not enough, consider the Aluminator 5.2L XS. At 580 HP out of the box, about 100 more than the 3rd gen Coyote with more torque too. At least with a normally aspirated engine, you could modulate the power a bit better than a boosted application.

Or if you are after a non-coyote family engine, the Ford Performance 363 crate at 507 HP will do the job nicely.

Lots of options as far a engines go, my preference is to keep as much weight off the front of the car as is possible, that is why I did not include big blocks. A 351 based stroker would be similar to the 363 with a bit more torque.

With the low weight of these cars, big torque equals wheel spin. One of the reasons I prefer the small block or modular engine families. I used a 4.6L DOHC engine in mine from a 2004 Mach 1 donor. Good HP and torque for my first Cobra. The second owner has it now and recently bought a first gen Coyote to bump the HP another 100.

I have 2 cars, a Mkll Cobra with a mildly modified 302 (93 Mustang engine) making about 300Hp and a Gen 3 coupe with Dart block 363 stroker making 450+ Hp. to give you a perspective on what 2 power levels are like. Both cars have high performance street tires on them. The Cobra is very easy to drive and you can slowly put the pedal to the floor in 2nd gear in a straight line and it will not spin the tires. The Cobra has been on the road since 2004 and I have over 40,000 miles on it including a few track days. I have not put the pedal down in the Coupe in the first 3 gears, I did spin the tires shifting into 3rd at about 50 mph with just a fast shift at part throttle. On the highway passing 1 car the Coupe in 4th gear will go from 55 to 100 mph and it is accelerating harder at 100 than it was at 55. The coupe only has about 5000 miles on it and I am still getting fully comfortable driving it.
These cars are so light that Hp levels in modern street cars do not compare. My coupe has about the same weight to power ratio as a new Z06 vette but without the modern traction control etc.

I say go for the HP and work out some really sticky tires like drag radials. One of the Nitto tires they say is specifically designed for the front combined w/ their drag radial rears. So there is a start. In my driving I know that it is relatively common to be able to do a 10-70mph blast w/o attracting attention. The problem w/ big HP is you usually can't go to full throttle in that speed range. I absolutely think that there is something psychological about being at full throttle. So a 450hp FFR could be more fun than a 700hp FFR. One thing that could help is go for the tallest rear gear you can get. Another possibility considering the potential fit problems w/ be an old school Ford bigblock like a 460 or similar. I have been watching Engine Masters a lot recently and, while they are usually Chevies, I am surprised how high they turn big blocks. A recent show they made no specific comment about it but the big block (way> than 427 but I forget the exact #) the hp peak was at 7400. That amazed me.

I would recommend street tires for novice drivers. They will break loose before you get too deep into a situation.
I run super sticky tires, but have a fear of going over the line, which keeps me in control.

Last year I bought a wrecked 2018 GT 500 with 2200 miles and stripped everything out of it with the intention of building another roadster with this as the the powerplant. The more I researched the install with all the plumbing, intercooler, etc., and the power which I probably didn't need, I sold all the parts. Probably one of my better car related decisions.

[Hoooper]

Coyote with a blower will get you the same power for way less, then take 20% of the money you saved and spend it on a good engine management system with traction control

[k-roy]

With great power comes great responsibility...and the need for bigger brakes. Need to bring up the thread with 1300 hp Mercury Comet?

If you are wanting the HP to be faster, might benefit from Traction control and a 10 speed dual clutch transmission.

That's close to what the Super Snakes that Shelby built put out. Originally there were two until one went over a cliff.

And here is that Sacred Snake that met it's fate:

I'm right below 600 HP right now and I think it is pretty manageable. You don't have to always stab the throttle. In fact on these cars you should never stab the throttle, but I think FFR gave us a beautiful canvass for us to create our vision. If you want that engine and understand its capabilities, then it's up to you. I love mine and wouldn't want it any other way.
