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

[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...isted-sr20.php

Just to be different, 427 SOHC, side oiler, dual 4 barrels.

[j.miller]

22cc single cylinder hit and miss diesel(or peanut oil) water pump engine from 1922.....gonna set a land speed record I am !...da Bat WHAT ! I'm removing the governor !

[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.

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.

[KenWilkinson]

ooow, 60 degree. Right on!

[Taz Rules]

This may have been covered, but what engine was it designed around?

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

tough call. Oh wait, I'm poor and can only dream anyway. Ferrari V12!

I really hope you can get that v12 working as that would be very enticing.

[MPTech]

Not a Viper V-10, those sound like turds. not a V8 and not a V12.
I like the GT350 Voodoo!

[Hobby Racer]

This may have been covered, but what engine was it designed around?

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.

When you are done removing your governor, you are welcome to come to Colorado and remove our governor.

Another look at the LS v12 engine.

[David Hodgkins]

I'm going one of two routes at this time:

Coyote or Electric.

Final decision is FAR from complete!

[Quincy]

I am surprised no one has picked that Australian V12 they had in it at the show. Apparently you can tune/ upgrade it to 1500HP.

[crash]

Not a Viper V-10, those sound like turds. not a V8 and not a V12.
I like the GT350 Voodoo!

I agree! I think that would be my choice.

[hogauto]

Please come to Pennsylvania after you’re done.

GM LS9 6.2L or the Hellaphant...

[GoDadGo]

How About A 572 BBC Tall Deck?

https://www.jegs.com/i/Chevrolet+Per...RoCpa8QAvD_BwE

They only make 720 Horsepower.

[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.

but! but! but! HORSEPOWER IS EVERYTHING!!!

[donshapansky]

Did you see the RIP for the poor gentleman in the Supercharged Coyote Roadster on here a few days ago?

[narkosys]

I guess there wasn't enough sarcasm dripping off my post. I will endeavour to do better next time.

But I do agree with what you said.

I really don't understand this almost fetish like need to have as much horsepower in a car as possible, especially in cars as light and agile as Factory Fives.

[Tuftster]

How about a Mercedes V12 with equal length headers? Might not be the fastest engine but sure would sound good.

[MPTech]

What is the engine they put in the late model Jag's? One of the best sounding cars I've heard. (besides the GT350)

[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.
