Potential Voodoo Engine Swap

[torque124]

I agree with the intake being always the least restriction in a stock engine like this. If one feels or shows gains with an intake swap, it is always up the top, with loss of power down low. The car almost always loses general drive-ability around town, if that's a word.

Yeah no doubt, and I completely agree with you there. ITB's would be a dream but even dual setup would definitely be a first step towards improvements. I actually think making a lot more power with this engine is going to necessitate much lighter internal components.

I think Jamaal Hameedi said the pistons are actually lighter than a 458's and the rods are as light yet more robust. I know the crank is heavier but to what end really. Probably doesn't matter THAT much.

Wasn't the Voodoo FPC something like 20lbs heavier than that in the 458 (3Xlbs in the Ferrari vs. 5Xlbs in the Shelby)? I would think that matters VERY much. These cars are legit, but in the last GT350R vs. ZL1 video, they complained about how slowly it revs compared to every other FPC motor - even how slowly it revved versus the LT4 in the ZL1!

Pretty much the only reason really. Take a Voodoo and delete the cats and tune it on 93 octane and itlll make more than the 580bhp advertised with the CPC.

Simple physics, the CPC version without some other significant changes (which I don't believe are evident with the Aluminator) cannot make more power than the FPC version of the same engine when levelling the playing field in regards of emissions and durability standards.

Stock 350 with tune and cats removed will not gain 55hp. Period.

There are several reasons Ford went away from the voodoo for race applications and it isn't because they wanted to "preserve the exclusivity of the fpc to the gt350".

If you are truly looking for a Voodoo swap, the cam shafts should be a lower priority and leave little for improvement other than a full out race car. I am fairly certain that I Read the specs put the stock camshaft lift in the .610 - .620" range. When I return from this trip I am on, I'll look that up to verify.

I think it's 48lbs. I have no issues with rev response. Sport Mode and Track. I can see how that may be the case in normal mode though, it's a touch lazy.

I had a thought...the CJ intake vs Voodoo intake test were done with respective adapting throttle bodies. I wonder how the Voodoo intake would do with that big honkin' twin 60 on it in a theoretical world. I fully get it can't technically be done but still an interesting thought.

No but it's not nearly as snappy as it could be.. all the weight they saved by gun drilling the crank they made up for in counterweight. The zl1 revs quicker than the 350.

If I had a non-emissions car and wanted to drop in a Coyote-based engine, it would be a 5.2 Aluminator all day.

Cheaper and will handle anything you throw at it.

If I were going for cheap I would do a junkyard Coyote.

Well, me too, but I was talking within the cost realm of a Voodoo....

I agree with you there.

I don't think that it was for that reason, but rather from a durability standpoint, but they did also say the 350 would be the only car to have the FPC so...

Can you explain then how the CPC version makes more power then? We seem to have already come to the conclusion that the cams are maxed as is, what else can be done to aid in power considering the only changes that I'm aware of is the crank? CPC cannot flow as much as a FPC considering the engine in question remains the same otherwise. Genuinely curious as to how else they would have improved the aluminator for it to make more power, or if it simply has more aggressive components that I'm not aware of that don't have to fit within their durability testing and standards?

I think it actually sounds like it revs faster than it does based on the tone of the engine. But have you actually driven a ZL1? If so, does the LT4 rev significantly faster than an LT1? I know my father's Corvette doesn't rev anywhere near as quickly as the Vodoo, and both he and I share that train of thought.

Though I guess if the LT4 has forged internals or any other differences it could make a difference, but I just don't see how it could be made to make that big of a difference, because LT1 vs Voodoo it isn't even close :shrug:

I've Considered it

Honestly, I would think a 5.2l aluminator would be a better swap and cost. Most of the wrecked cars, the voodoo engines are still selling for primo dollars.

I've thought about the 5.2L aluminator too but it just doesn't excite me as much. But if I cannot find a voodoo that is reasonable, the aluminator is pretty much my engine of choice. However, so far I've seen 3 different Voodoos sell, and not for too much. The cheapest one was at $18,500, with the stock tr3160 transmission, and everything else needed to run the engine (wiring harness, reservoirs, etc). The aluminator is selling for $17,500 I think. The voodoo would actually be a bargain.
