Ordered.

It's possible I may try this with the Mishi Tube and aFE filter. For the price it's not a big loss if I don't like it.

Do it! You will create a monster ;)

Correction, they are Charge Motion Control Valves. Close enough though ;)

My best numbers were close. Airaid bigtube, green filter.

Interesting stuff. Sub'd because I love the oddball stuff.

I'll bet a good tuner optimizing the VCT could net stock upper RPM power and keep (or better) the bottom end. Especially with a little blending in the ports and TB opening.

I assume the initial testing was done with a GT throttle body?

Yes stock TB. Next stage is 350 TB AND HEADERS, along with tune.

You guys should swap to F150 cams too, turn your 435hp engine into a 365hp one! Get a tune to lower the limiters to 5k, this is Merica, we don't need no revs here.

Voodoo Cams!! Now we're talking.

Keep the revs higher then. If that's what you want, buy a SRT product, torque for days. Its like buying a civic si and complaining about the power below 6k and wanting to take away vtec, it just doesn't make any sense.

Uh... I have a V8. It should act like one. Not like a turbo lagged 4-cylinder. :lol:

VCT doesn't dictate peak power for an intake manifold, runner length does. RPM's are power, lowering the RPM's lowers power potential.

Correct, to a degree.

But VCT allows manipulation of lobe separation angle and valve timing relative to crank rotation, both of which tie directly into how well a given intake works.

I maintain my opinion that a GOOD tuner that knows what he's doing with respect to VCT would be able to keep stock GT performance up top with greatly improved midrange and bottom end using this manifold if overall airflow is similar. Might take a lot of fiddling, but.....

This is my hope!! I've talked to a few guys. Here locally to me is UMS Tuning, they've don't the last 2 DYNO runs on the car.. so this will be the tuner for the next stage of this build.

I don't agree. There isn't much to change on the VCT on a relatively stock car, Ford did all that work for you, some if not most tuners leave VCT untouched on bolt on cars (unless they have a manifold change) because there isn't anything to be gained on a bolt on car. If the runners aren't the right length, it doesn't matter what you do, it won't work.

Yes stock TB. Next stage is 350 TB AND HEADERS, along with tune.

This is my thoughts too.

F150 intake
GT350 TB
GT350 cold airbox and filter
long tubes
E85
Tune

All of those parts are pretty cheap through levittown ford or white bear lake ford.

Should be an easy way to make 400+ hp and 400+ tq

Cams would make it interesting too if someone decides to do that.

For the price of this manifold cant really go wrong if i dont like it put stock back on or buy a boss/gt350/cobra jet after oh well.

All that would be WELL over 400 whp. Probably around 430 whp and torque.

I didn't say that or even hinted at that.. Rule of thumb SINGLE plane for high RPM 6500- up

The single plane vs dual plane debate doesn't really apply to late model EFI manifolds. Technically speaking all port EFI manifolds are single plane in design, even ones with long runners that make gobs of torque below 5k rpm.

Dual plane intake designs are really only beneficial for enhancing the vacuum signal to a carb, which typically gets weaker at lower rpm, hence the old school rule of dual plane for low rpm, single plane for high rpm. However even that rule failed to account for runner length and design, because there are dual planes that still perform very well above 6k as well as single planes that do well below 6k, but with injectors providing fuel instead of a carb, it's really an irrelevant subject.

So does this still have the IMRC valves like the regular GT manifold? And do they work with the GT computer

 

[Boggus]

So order the mani, plug the hole. Install and car works and is better, stronger, faster? So tempted.
