Guess it has different heads than ours, what else?

And the intake is on the "right" side.

Looks almost like a Mark VIII style intake.

I'm very curious the mods they made to coax 400hp out of that motor.

[RoyLPita]

I wonder what the torque figure is.

:down: !Blah! I tough for a moment that you was reffering a Crownvic or Grand marquis but a Mustang... :shake:

My guess is the 3v gt heads with variable cam timing. Maybe the heads are massaged a little or better valves, more rpm, etc. Decent headers and exhaust and a nice intake. It may be set up to take in air from the WS cowl.

Hmmm, 2008.5, I may be ready for a third car!!

according to the thing it's the 4v gt (as in gt40) heads

I see that, like a Marauder

Even better.

That says a lot for the potential of the GT heads, almost 100 hp.

[RCSignals]

all this from a 'puny' 4.6L engine, that doesn't even have pushrods

Bullitt with 400 n/a hp sounds perfect to me. :drool: That would mean with some gears and a few bolt ons it may be in the c5 z06 territory.

Are you guys thinking what I'm thinking? Stock 400hp 4.6DOHC 100 extra horses Are you thinking what I'm thinking? If so let the engine swapping begin.:beer:

i'd be curious about the rotating assembly too, and compression ratio. Wonder if it'll have any stronger or forged components than our motors.

Also where is that 400hp being made - i.e. will it spin faster than ours, say above 6200rpm...

[MarauderMark]

What would the cost be for crate buy from a dealer/ford? I mean itsa bout 7k for a cobra so what 10/11k?

[ctrlraven]

Wow that is awesome. One thing though, I wonder if their going to have the same setup as the 03/04 Mach1's were the manual versions had forged internals and the automatics had the regular internals. If they come with forged internals I think this would open a brand new door for us. I'm definitely going to follow this and see what comes of it.

[stryker]

That is awsome!:nono: Not for me.


STRYKER. :burnout:

I was thinking exactly what you were thinking. That should bolt right in. An extra 100hp is like bolting a S/C on but still N/A.

People have gotten 400 n/a rwhp out of a 4.6 4v motor. Why do the motor swap?

Which 4.6L are you talking about, it's definitely not ours.:confused:
N/A RWHP, not at the crank.:nono:
Engine swap anyone ?:bows:

I agree, I have most bolt-ons and Im pulling just under 300RWHP. After the header install with pipes I may pull 330RWHP. To hit the 400RWHP mark N/A, Your looking at a major shot of NOS or internal engine work.
However, Brake HorsePower is different, 400BHP can be done with a N/A Marauder without having to go inside, But you are Maxed out on Mods. Take a engine with 400BHP stock, and then start to mod it. You may hit 500BHP before even considering a blower.

Engine swap indeed!

Yeah I know RWHP > Crank HP. I said people have gotten it, so it's not a Ford factory 4.6 People have achieved that with Head/Cam/Intake work along with all the bolt ons and Full long tubes.

Blackened, you have awsome n/a numbers without having touched the exhaust. I bet if you went with full stainless works exhaust, ported heads (either fr-500 or your stock ones) along with cams and a ported intake you would have a hell of a beast. I don't think a Marauder will hit 400 at the wheels due to the auto sucking too much power, however it would be up there.

Do a search for Nazman he has gotten some incredible numbers out of an n/a 4v 4.6 currently though he is running a big bore I believe and putting down 450 n/a to the wheels. Yes it is in a Mustang and there are some differences but it is possible to build a beast of an n/a Marauder.

"Nazman (from Mighty Mustangs) (337/337 SAE) PI, 99 C head. Bolt on HP Champion." and we are supposed to have much better heads
"Nazman (from Mighty Mustangs) (410/333 SAE) Owner Ported FR500 Heads/FR500 Cams/FR500 Intake. 4.6L HP Champion." Bolt ons + H/C/I = Big power out of a 4.6

Yep, 12.9s with OEM 3.55s...heh heh heh...:D

Thanks.
Kooks long tube headers along with hi-flo cats and mufflers are coming in March.
Thats my B-day gift to myself. As for Heads and cams, Thats Big $$. That would be way down the road!
Its probably cheaper bolting on a S/C and getting stronger numbers with stock internals.
I do Believe being N/A and pulling strong numbers is more impressive.

[Blackened300a]

The actual engine swap would be the easy part, The issue would be using the Marauder Computer to run the Fly-by-wire that Ford has been using on most of its vehicles.
If you use the computer from the Mustang, The next hurdle would be that if the Mustang has a Automatic its most likely the 5spd. Im not sure if you can tune it to work the Marauder's 4spd.
Looks like a engine and tranny swap would be the solution. Then you have the 400hp and a 5spd Auto.

[94_302]

Your right while it is more expensive n/a numbers are far more impressive than bolt on blower numbers. With the exception of the built motor high hp beasts we are seeing.

I doubt it would be an auto. If it's going into the Bullitt, the last time they did a Bullitt it was a 5sp only. But then again it was not a best seller, so maybe they will do the auto to get more sales.

Sorry, thats the old Boss motor, Ford killed the project a little while ago...

I'll reserve the right to wait and see. That thread isn't convincing.

Fourcam is the man, he called the 03-04 Cobras and the GT500 right. He has had the best info on the new hurricane line, he the man! :beer:

[juno]

Why would you swap the motor? If it's a 4.6 making 400 hp, it should be all in the heads and intake. The block itself should not be any different. If it is, then it's not the modular block and you are talking increased hassles for the swap.

[buickconvert]

400 hp from 281 cu in seems reasonable if that power peak is at 6300-6400. That's an excellent but achievable BMEP of 180 at peak power. I don't see why a Marauder engine couldn't make that with stock ported heads and a hotter cam. Even a BMEP of 175 would yield 400 hp at around 6500 RPM. You'd lose a lot of low-end, but I bet this mustang engine doesn't have much low-end either. I'm speaking from general engine knowledge here, not mod-motor specific, so please don't flame:flamer:

Then again a stock Marauder is only a BMEP of 148 at peak power and 170 at peak torque. . .not exactly stellar numbers. Lots of room for improvement.

FWIW: BMEP is Brake Mean Effective Pressure. It's calculated from the following formula: BMEP = torque*150.8/displacement(cu-in). In a simplistic sense, it's a measure of how efficient a pump an engine is.

On the olds forum, one guy built a dyno tested olds 455 that had a BMEP of 179/96 at peak hp/tq (pump gas). That's an oldschool pushrod/carbed engine. :coolman:

That may be. After reading the thread, I'm not convinced on this one.
