5.4L aluminum block with steel jacket cylinder inserts, forged pistons, and cobra heads. That's what I'm talking about!

BTW: Triton intake manifolds are dual stage resonance. Just like in Taurus SHO YAMAHA engines. But instead of utilizing a two runner lengths, they use separate plenum just like in prosche 996 GT3, a valve inside the plenum close to force a second resonance. I haven't actually seen Triton computers utilize that valve, perhaps because of emissions. You can open that valve with a simple switch connected to your battery and the valve. You should see a difference, you may not make more power because ECU will not give it more fuel and you'll go lean, but you definately will see difference. It takes some ECU tuning or even a different ECU to utilize that valve.

 

Thats a really interesting idea, basicly its just like the Mustang/F150/Windstar 3.8/4.0/4.2 engine with splitport heads. There is a second set of runners that open and close based on vacuum. So what you are saying is that there is a separate set of runners that are closed off and not used but can be used by putting power to it?

Do you know anywhere that has pictures that I can look at so that I can do this? I dont follow directions too well so pictures are the best for me.

Anymore cool tricks for it?


Thanks!

 

No. I'm not talking about separate runners for each cylinder, I'm talking about split plenum. Read this to get a basic idea: http://www.autozine.org/technical_sc...ariable-Intake What triton engine have is called Resonance intake system, they have a dual stage one, two resonance frequencies.





This resonance intake system is only possible on V shaped or boxer engines. It won't work on inline engine. It just happens that the Ford Triton line of engines have this valve in the plenum, but their computers don't utilize it, at least I haven't seen utilized yet. The valve is located on the plastic plenum, under the runners, in the front. It takes 12 volts to flip it. It is basically an electric motor to which you give power and it flips the valve, which connects the two parts of the plenum and introduces a second resonance, you can take it out and have a look at it. When flipping it, maitain proper polarity.

I was going to install it on my crown vic, but I crashed before I ever got a chance to do it. I have a complete manifold in my closet, ready to install. In mustang, I don't think I will do it, since hood clearance will be redicolous, something like 4 inches above the hood. I bet it will be possible to cut that plenum and JB weld it to make it fit under the stock PI manifold.
