How the GT350 Voodoo REALLY stacks up against the competition

[DrumReaper]

You say potato, I say potato. Bro.

Buhahaha... Bro. Lol.

Well, Bruh, the Voodoo is no doubt not going to find its way into a truck as did the Lambo/Dodge v10 did into a Ram. So, there... Problem solved. :cheers:

Viper engine never went into a Ram other than the SRT-10 Ram, which even had a manual transmission.

Im not sure why we are talking about the viper engine, totally different beast.

The article focuses not only on ultimate power output, but volumetric efficiency and rev range =), which is where the Voodoo shines compared to your traditional american V8

I don't know how you couldn't call that a long tube. It does not get much better than that equal-length 'long tube' for a production header. Most aftermarket attempts have not made more power than the stock S65 header.

To get 380whp on an S65 (and i'm sure in the 440whp stroker ratings), you need to remove the cats.

While that is a very good header design I've gained 20 whp with aftermarket 'long tube' headers on a boosted application.

The stock equal length design is very good. You aren't going to gain much of anything as you basically are alluding to.

My headers are a modified stock design.

Regarding how this applies to the Voodoo V8 I think you guys will definitely see gains with aftermarket designs although the greatest gains will come in boosted applications and from highly tuned NA setups as the stock design no doubt is pretty good as well.

Maybe we are getting ahead of ourselves here but bolt on tuned GT350's should see ~520 whp even on 91 pump. The give or take is the headers.

Steve Turner mentioned the FP engineers told him as far as aftermarket the car would benefit most from a Tri-Y design. Can you explain that one as to why they would make that recommendation?

I don't see much room for hp in bolt on aftermarket parts staying NA. The gt350 has a cold air intake, full exhaust with X pipe and a decent set of headers. A better intake would be minimal, a better smoother x pipe would be minimal also. A better header with a good tune will give the best performance hopefully.

Without these semi aftermarket performing parts, this gt350 would be in the lower 400s to the wheels.

To be honest with you there are going to be tri-y proponents. As there are equal length proponents and also people who swear by larger diameter long tube design.

I don't think I can comment on the header design as I'm not even familiar with it at this stage. I just know that the Voodoo is showing incredible volumetric efficiency which means the stock design is not exactly bad or a huge bottleneck (or even minor bottleneck) at this point.

Can it be improved? Yes, probably more so than the S65 design which is almost perfect.

Will you see gains as large as say on a Coyote? I don't know yet.

You're looking at it as already tuned. It's not an uncommon view.

However, you are not taking into account the GT350 has a larger engine than a Coyote, revs high, is higher compression, but has to make some compromises to meet regulations.

If you look at the stock graph of the motor there is a noticeable spike at one point early in the rev range. Can this be smoothed out with say higher flow cats and some dyno tuning? Maybe the torque curve even moved up through the range? I'd say most definitely.

Once you start modifying a high volumetric efficiency motor gains are harder to come by as the factory already did a lot of work. That doesn't mean there are not gains to be had. This motor is not approaching a naturally aspirated VE limit yet and there is room to play. I'd expect nice tune only gains with the ECU probably set from the factory to be conservative and pull timing like we are seeing with many modern performance cars these days.

The Ford aftermarket is robust and we will see these things over 500 whp with bolt ons very, very quickly. How much headers and their various designs may or may not add we will see.

Any type of correctly designed header is going to blow away the manifolds they are using on these motors. If a Boss can pick up 30 with long tubes, I'm betting 40-50 on the Voodoo. More RPM's, higher output per ci, and equal pulse dynamics in its favor over the Boss. With a tune and good fuel to take advantage of the 12:1 ratio and standard mods adding 80-90 hp is going to be easy.

I don't know about the gain numbers, but I agree with your point about fuel.

If someone out there decides to configure the engine in order to brag using peak HP numbers, there are also probably quite large gains available. Just thinking about how flat and broad the HP curve is right now, I'm sure different cams could make it more peaky and give you a much higher peak number to brag about on the internet. ;)

The same could be said about a short runner IM like the Boss had. I'm sure it could pull over 9K RPM and make impressive peak numbers, but the low end would suffer. I'd love to see someone try it just out of curiosity.
