What Motor are you thinking about putting in your F9?

[stack]

Just thought this would be fun to see what people are thinking about stuffing in this beast. The car looks so exotic to me I am not sure I would want a mass manufactured engine in there. I'm thinking the 5.2 Aluminator, C8 corvette donor motor or GT500 motor. Let's hear your thoughts

stack

[wallace18]

LS3 600-650HP with 6spd manual.

[NAZ]

If a V12 LS style engine fits then I'd be thinking of a large displacement BBC making lot's of pump gas friendly power without all the typical power adder components that make packaging a challenge and add additional weight and complexity. https://www.shafiroff.com/chevy-pump-gas-engine/632-bigdawg-twisted-sr20.php

[KenWilkinson]

well, not buying it, but Surprised no one has mentioned a Jag V12 or BMW V12.

[Derald Rice]

Viper v10. Available, but not necessarity cheap. grind the viper name off of the valve covers so that the viper name was gone.

[Garage Guy]

Well an LS of course.


Just kidding

Aluminator

[Garage Guy]

If Factory Five decides to build it I will sell my serial number 002 25th Anniversary Edition too buy it that car looks freaking awesome.

[Papa]

The Mercedes bi-turbo V12 might also be an interesting option.

[Jim1855]

No plans but still you asked.
LS7 @ about 600hp NA & T56
Mast Motorsports would be a good place to start.
Jim - easily converted to the "dark side"

[narkosys]

I am thinking more along the lines of a V10. One thing I do know is that I DO NOT want it to sound like a muscle car. To me, this car is an exotic and should have the proper song. I may see if I can wiggle one of Borla's polyphonic exhausts into the mix.

[Boydster]

Bmw v12

[GoDadGo]

I'm thinking of the..Kaase Boss Nine..would be a great powerplant for the F-9.

https://jonkaaseracingengines.com/shop/boss-nine-parts/custom-bulit-boss-nine/

The F-9 will be expensive, unique and an all aluminum Kaase would look cool, be cool & really scoot this car in style.

[delta0014]

Aluminator, no question.
No real interest in the F9, but if they ever made a Carbon Fiber bodied Dayton Coupe, I'd sell my Cobra and put my deposit down on the first day.

[Chris @ Forma]

First off this is an absolutely crazy idea, however, we have been tinkering with an idea for a couple of years now and I think we are going to start on if pretty soon. As many of you may know, we are pretty dedicated to the Coyote platform. Our Coupe makes a bit over 800hp (700+ whp) and is pretty much bulletproof. Anyway, staying with the Coyote theme we are seriously considering building a Coyote derived V-12 7.8 liter monster. Should be 700-725 hp NA.

We are pretty big in 3D printing and will be partnering with a local company to 3D print the block mold (3D printed sand) and our parent company works with a couple of aluminum foundries that can pore it for us. The block and heads will fit on our 5-axis mill so we should be able to finish them in house. We'll go outside to have the crank and cams manufactured, other internals will be stock Coyote except for some of the accessories such as water and oil pumps. As this will be a 60 degree V these likely won't package.

Hope to post some images as we make progress. This assumes we are able to work in close proximity to others sometime in the not to distant future. In the mean time everyone stay safe and keep your distance.

ooow, 60 degree. Right on!

I'd love it with a big LS7 or even an LS3.
But the thought of a flat-plane crank engine and the European sound.... mmmm

[Hobby Racer]

Designed from the new coupe chassis so anything the coupe can use this should be able to use.

[bobl]

I really have the bug to build a Coyote, with good parts, Holley ecu and a procharger. It would easily make over 800 HP with conservative boost That would work really nice in the F9. Holley also makes a really cool digital dash that might be just the ticket. If I have another car in me this might just be the one. It really depends on the price point.

[Chris @ Forma]

Bobl,
We are building a Coupe right now and were originally planning on a ProCharger on a Coyote. When we were purchasing all the pieces parts, ProCharger didn't yet have a solution for the Coyote. We looked at constructing our own mounting hardware, belt tensioners, etc. but we couldn't come up with a solution that didn't preclude an A/C compressor. Ultimately we ended up with a Holley Super Charger.

Chris@Forma

[Chris @ Forma]

Yep, 60 degrees, otherwise the crank would have 12 rod journals instead of 6. This would have made it difficult to maintain the same cylinder spacing. Anyway, we are excited about the prospects. It is just difficult for me to work on the design from home. I'm in the old fart high risk category for Covid-19 and so I try only to go into the shop when no one else is around. Hopefully, the world will settle down soon so I can really get back to work.

[donshapansky]

A car that light without ABS and Traction Control at a minimum will not get around a track as quick as a Z06 or something in that range of production car, on the street all it will take is one mistaken application of power and you will be without a car or worse in the hospital. After driving my Coyote HR33 with a slippery converter for a couple of years I'm a lot wiser about power to weight ratios. If the engine you choose has wild camshafts with no valve timing controls it will be a miserable experience, trust me.

[Chris @ Forma]

Dan..ski, I agree, This car will probably scale out about the same as a Coupe. Ours makes just under 800 and it will light the tires at any speed and in any gear except 6th. Any more HP/Torque just increases the tire budget. As for Traction control, we already do this and I am still looking for an ABS system that is not $12k.

all very capable of easy Turbo power. And sounds. Don't see many V6s that I like. Mostly because the V6 is usually a 90 degree engine. Should be 60 Degrees to sound right.

[TBull]

I vote for a twin turbo aluminator with Borla exhaust. It would be up in the 700 hp. My question though on the car is the aerodynamics at high speed. I've always wanted to build a car that was capable of 200 mph, but not of its stability at that speed. The coupe is proven at that speed though.

[Chris @ Forma]

Tbull,
Our Coupe should be pretty well north of 200mph, though we have only had it to 180. At 180 it is very stable and even without windows, it is amazingly quiet with virtually no wind noise at that speed. When I was at FFR late last year, I had the opportunity to look at the design in quite a bit of detail. Though I have not worked on aerodynamics since my college days, I am feeling pretty good about the body shape. That being said the drag is product of the drag coefficient and the projected front area. The frontal area of this car is substantially larger than the coupe as it is a fair bit wider. When I looked at it the width was somewhere in the 81" range therefore if Cd were the same as the coupe it would still require more power to achieve the same speed. That being said...It looks fast sitting still which isn't bad.

We are super stoked to get started on one as soon as possible.

I would love to find a way to stuff an AMG 5.5l V8 Biturbo with the 7 speed MCT twin-clutch transmission into a build. It's rated at ~575HP but rumor is that's conservative, and the real number is north of 600HP. I fear that the electronics voodoo involved in putting this into a project car would be horrendous.

[Manta9527]

If I could buy one of these F9s, I would put a Hellcat in it, backed by a Bowler Performance 4L80E with a Lokar Sport Shifter or a Tremec T56 Magnum.

[Glen Davis]

If Chris at fromacars.com produces a V12 Coyote then that motor with an 8-speed paddle shift transmission. If you want more power then you could twin-turbo it.
Another choice would be the C8 Corvette Z06 5.5L twin-turbo flat plane crank engine with an 8-speed paddle shift transmission.
You can’t beat the paddle shift on shifting speed and with the power you can keep both hands on the steering wheel. A lot of exotics are using automatics because of the faster shifting.

I'm not certain that I would want more than 400hp considering I want to actually drive it around town and not at a race track.

Yeah, but it’s a Ford baby! Almost the same torque at 4000 vs 5200 rpm

[JohnK]

That Ford Godzilla V8 is clearly all about the torque. Looking at the HP number totally misses the point. A Gen2 crate Coyote makes the same HP but I guarantee that Godzilla will not feel like a Coyote under the hood. It'll feel like a diesel, which is what they designed it to compete with.

I am generally a fan of Ford engines as I believe they are easier to build more power with, although usually end up costing more per HP than GM because of parts availability. That said, the GM 6.2 525 also builds more torque and is a much smaller package. Oh, and because it is much smaller displacement it likely does it with much better fuel economy and is lighter. About the only reason I can see to use the Godzilla engine is price, but because the ECU questions are still out there the LS may also be cheaper once everything is installed and running. I just don't see how this would be a good engine for a relatively light sports car. The Voodoo engine makes much more sense to me if one wants to stay with a Ford...although it has some drawbacks as well.

Voodoo. Talk about a great sound at 8500 rpm...

[ram_g]

Ok that's seriously impressive! I did not know Mecury Marine had an automotive division.

Actually they've been around for a while. 30 years ago they built the (Lotus designed) LT5 engine for the C4 Corvette ZR-1: https://www.mercurymarine.com/en/us/legacy/history/week12. Not sure they've had a sustained automotive presence though.

[Jim Stabe]

Not planning to do one but if I was, it would have to be a Voodoo. They are just too nasty sounding at 8500 rpm.

[mikes69gto]

I'm a Chevy guy...but I thought it would be cool to put a Ford Voodoo motor in one (with the flat plane crank) just to get the high end exotic sound out of it.

[Ajzride]

Has anyone ridden in a voodoo swapped car yet? I've heard that the mustang has active dampening for the motor vibrations built into it, and that the voodoo would be brutal in a car not designed for it.

[edwardb]

Has anyone ridden in a voodoo swapped car yet? I've heard that the mustang has active dampening for the motor vibrations built into it, and that the voodoo would be brutal in a car not designed for it.

Yup. Was told that directly by an engineer at Ford. Said there are dozens of unique parts on the GT350 for that very reason, and the engine will never get put into another car at Ford. Also said the rigid frame, headers, etc. for our builds would be incompatible. Things will break. Said that while in my garage shop looking at my Gen 3 Coupe chassis. While the flat plane crank engine sounds cool, and certainly revs, a stock Gen 3 Coyote revs to 8,000 (been there done that) and with just a few tweaks will produce just as much power. The recently introduced Gen 3 Aluminators are another option with even more potential. Cool factor on the Voodoo is high. Practical factor, not so much.

[JohnK]

Can you even buy a Voodoo engine as a crate engine, or do you need to find a salvage? I see that Ford Performance has a 5.2L Aluminator 5.2 XS but it's listed as a cross-plane crank. 580HP out of the crate is pretty healthy but the $23K price tag... wow.

No. The Voodoo is not available as a crate. And the same Ford sources I cited before said it won't be. So people are either getting them in salvage or building them up themselves by getting the unique parts.

[ChopperJustin]

Korman Autoworks BMW 6.0L V12 would sound pretty awesome!

[crash]

I'm a racer. I put a couple thousand miles on an engine and then rebuild or replace it. Yes the flat plane crank engines have their faults, but I have seen (and heard) them in race cars previously. Didn't note any particularly deal breaking issues. Are they high mileage ultra reliable engines like most of us are used to from a OEM crate engine? No. Does the VooDoo sound wicked and make a bit more horsepower with the flat plane crank? Yes, and maybe. Can you make as much HP as you would ever need with an offset crank? Yes, but if one is going to do maintenance at low intervals anyway, why not have that magical sound being produced? That is why I chose the VooDoo, but I have to agree with you that it would likely not be practical for most builders.

This is an aspirational build for me because as a college student, I can't afford to build one right now, but building a Factory Five F9 has been my dream since it was announced as the GTF. After doing a bit of planning for my aspirational build, which I'll probably be able to do in around 5-10 years if I play my cards right I've come to two very attractive engine options. For me ultimately I want to build the car, but I want to enjoy the car and drive it as often as I could get away with and one barrier for me would be the fuel efficiency of the engine.

I'm currently used to my dad's old ford with nearly 200k miles on it, but at least it gets 20 mpg. It would be hard for me to move to something without at least comparable mpg and still feel alight driving the wheels off it as frequently as I'd like... especially if I want to build it at a younger age, then double the gas prices is more significant relative to my income.

With that in mind, while I'd love to go with a Ford, I also want a minimum of 600 hp, which really limits my options, and I don't really see any options from them that meet both of these criteria that excite me. Instead, looking at chevy, like the idea of an LT4 or an LT5, they get nearly 3x the milage of their LS counterparts at the cost of a bit of reliability from what I've seen. I think it's a fair compromise. And since the fords are more expensive per hp I think the search really stops there, but idk.

I especially like the idea of stuffing one of these engines in that lightweight car. Now I've estimated the weight of the car to be 2100 lbs, with a payload of 400 lbs (myself and a 200lb buffer). I put those into a physics calculator and that's a conservative 0-60 is sub 3 sec for the LT4 and LT5. What I like about it, even more, is I don't have to deal with any of the hassle of using turbos to meet my desired power threshold or any turbo lag. In a decade when those engines are depreciated a bit, they could be solid options for me, because while I want to build the car on a budget, I won't compromise so I'll save until I can afford to build the car that I want.

Thinking about the interior possibilities already has my brain spinning with excitement, I've got some ideas already stewing based on the Phil Frank renders but I look forward to seeing what everyone else does in the meantime. Cheers everyone:)

While that's an interesting thought of an electric F9, the Bulk of a Tesla's weight comes from its batteries. They would also be necessary to run the F9 if you wanted to run the Tesla motors. So while the F9 is right around 2500 lbs, there are 1,200 lbs of batteries you would need to install to get the motors spinning at their maximum performance. With the motors too, you're looking at a 4000 lb car at least.

I'm definitely a bit torn between 3 options. I loved my voodoo engine in my 2016 gt350, there is the v12ls that I got to see in person last June, and Nelson Racing has been teasing a flat plane ls. While I love the voodoo, I can't make custom headers myself. Also vibration will be an issue with flat plane engines. I'm hoping I get to see the v12ls fired up come June when I make another trip to factory five. That would be the best 30th birthday present ever!

I was thinking of a Mopar (CAT) Hemi motor.

So...assuming we'll have a 700 lb-ft torque engine in a <3000lb car. How does one produce enough friction to keep the rear wheels on the ground without, at least, doubling the car's weight?

[Glen Davis]

Traction control

[toadster]

AWD Tesla motors

Traction control

That's kind of a funny solution. Since traction control's purpose is to reduce power to the wheels - which defeats the whole purpose of having a big engine. Except, of course, bragging rights... :D

While that's an interesting thought of an electric F9, the Bulk of a Tesla's weight comes from its batteries. They would also be necessary to run the F9 if you wanted to run the Tesla motors. So while the F9 is right around 2500 lbs, there are 1,200 lbs of batteries you would need to install to get the motors spinning at their maximum performance. With the motors too, you're looking at a 4000 lb car at least.

I'm curious on the overall weight difference, to get to 85kwh you add about 900lbs in batteries, and then a Model S drive unit is like 300lbs, and then the charger and whatnot, but you remove the engine weight, gas tank/fuel weight, as well as rear end (depending on what you're using, could be chunky). I know it would still be heavier than a gas setup, but id be curious to the more exact weights?

something that came to mind. I wonder if you would be able to grab the entire driveline off an Audi quatro and make the F9 AWD.

Just looked at Summit Racing .... $ 6849.99 ... not fully dressed , but a good start ..... Mike :)

Something crazy. How about an Aston Martin-Cosworth V12? 6.5 liter 1,000 HP @ 10,500 RPM with a 11,000 RPM redline and emission compliant and weights only 454 pounds. All you need is $$$$

Not bad idea. Audi is good at stable operation of key components, Audi's transmission is reliable, it can serve as a basis for upgrading a car.

[johnnybgoode]

I'm not really crazy about EFI motors but if I had to chose I think a nice simple naturally aspirated LSX454 would be a great fit for an F9 project.

[Coxal_Dae]

Sadly I don't think a big single turbo 6BT will fit under the hood so either going with LS or 3/4 rotor depending on what the bank account says.

Whatyameanbunky not dressed? Just needs a belt and air cleaner :-)

[donk_316]

Viper 8.4L V10 and it’s small and light.

[Kay_B]

I would not mind a Ferrari or Aston Martin engine. They are reliable and powerful. I also like engines from old American cars such as Chevrolet or Ford from the 60s and 70s.

[Rigdotcom]

Contemplating an sts turbo 416 lsx that I'm building. STS to keep all the heat from the turbo out of the engine bay and save the carbon fiber.

[Chadillac]

I'm hearing rumors that the 2023 Corvette Z06 will have a flat-plane crank 5.5L NA V8 with a redline of ~9000 rpms. I wonder if Chevy will sell it as a crate engine and if it will have the same vibration issues as the Ford Voodoo engine.

[Jim Frahm]

I’d like the 4.7L Ferrari engine out of a late model Grand Turismo.

[RoadAppliance]

I’ve got a few thoughts on this one:
1) inline 6, Toyota 2JZGTE, Nissan RB25DET, or BMW B58
2) inline 4, Honda F20C with a little turbo to spool fast.
3) 3 or 4 rotor wankel, of course turbo as well
4) hayabusa motor.

Either way, if you hadn’t noticed I’m think high revving antics and a HP goal between 350 and 450.

[Mudpie]

How about the new Mopar Hurricane 3.OL twin Turbo Inline 6 cyl? Are they even available as a performance crate engine?

[RoadAppliance]

I’d be good with that too from what little bit I’ve seen on it. Wasn’t aware of it when I posted the three other I6s I listed

[Alan_C]

How about an LT4.

[gh426]

Since it comes Painted, red or CARBONED, 6.0L express van alum block, t56 OR CD009 with a fabot clutch kit, usable 1st gear ratio. maybe one big s470 turbski or twin, whatevers availible 4 asthetics or asmatics ur choice. since v8 weight is further behind front axle line vs V10-12 HENCE better weight distrobution.. all that saved up $ will put GAS / 50 ethtenol in it!!!. 50 state parts availibility... LS all of it!!!! anybody got a date or cost? of said F9, should it ever come to market.

I am thinking more along the lines of a V10. One thing I do know is that I DO NOT want it to sound like a muscle car. To me, this car is an exotic and should have the proper song. I may see if I can wiggle one of Borla's polyphonic exhausts into the mix.

My thoughts exactly. This is not a muscle car. it should not sound like one. As much as I love muscle car sounds (Ford Coyotes sing a heavenly song) it would just be awkward in this build. It would be the car version of a giant muscular man with a squeaky, high voice.

That being said, part of why I'm here is to look for ideas and a starting place to figure this out for myself.

It looks like we might have a year or two before we can pull the trigger, so I'm trying to plan and prepare as much as I can.

The Audi Ideas I've seen are nice. I'm kind of partial to Ferrari or Lambo v10, it's just up to finding a good one for a decent price relative to what it is that's also reliable enough to not need a rebuild.
