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.

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

Then head further down the road to Michigan and remove ours too please.

[Jimtmich]

I would do a Coyote. Sounds great and plenty of power for this weight.

[VRaptor SpeedWorks, LLC]

Is there a manual gearbox that would mate up to the HO Ecoboost that Ford uses in the new Raptor?

[Mudpie]

I would probably drop in a BMW 3.0L inline 6 turbo motor for reliability or a Ford 3.5L EcoBeast.

[Dragonfire]

The new supercharged LS5. Sufficient horsepower and a warranty. I love Ford engines but until until Ford releases a crate Voodo I think a reasonable alternative is the LS5. Let the stone throwing begin.

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

That is pretty cool looking and fits the exotic bill any idea on the cost of that thing?

How about something like this: https://treperformance.com/i-2390097...SABEgJD6vD_BwE

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

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've looked all over the net and no price for these which means crazy high price

[Quincy]

They cost about $30k.

[scottiec]

Has nobody mentioned Fords new 7.3 pushrod motor? That has already been stuffed into a Fox body, all motor was able to make 600 crank, and with a supercharger kit from whipple it is at 700. SIGN ME UP

[ibpilot]

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. The BMW V12 (M70) or even the tried and true BMW Straight Six with the right massaging would easily be a great and somewhat exotic powerplant...smooth to! http://racingpowerplant.com/bmw_m70.htm

[narkosys]

Let me pull something from way out in left field. The Connaught 2.0L V10 from the Connaught Type D Syracuse GT. Yes, 2000cc of pure supercharged goodness.

[Canadian818]

4 rotor of course. I won’t buy a early model mark 1 FFR kit again, but maybe after a couple of years of ironing out the details.

That would be a glorious engine to put in a F9!

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.

[Presto51]

Or you can really step up to the plate and go Kaase Boss Nine. http://www.jonkaaseracingengines.com...e_engines.html

Yes it's not cheap, but the thrill will give everyone a chill.

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/...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]

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.
