Looks like there's hex bolts holding the ball mount on.

 

I think it should be alright to test if the EGT's hit 1000 momentarily!?

Flat highway it runs about 700 or so, just wondering if I should back off before hitting 1000, or let it just run a little hot for the test, while climbing grades or accelerating.

I know guys run over 1000 lots, but I'm a scaredy cat lol

 

I might be off on this; but if you had 1000 * EGT's at 50 lbs of boost, and 1000 * EGT's at 5 lbs of boost, would it not be true that the higher pressurized air would be denser, thus transmit more heat into the surrounding metal?

I know it's the exact same temperature, but wouldn't denser air transfer heat faster to the steel and aluminum ?

 

whats your programmer beeping about during some of the videos? if you hook the vvt back up does the light turn off or do you need to clear it after? im curious about unplugging it just to hear what is sounds like!

 

The programmer has the EGT alarm set at 1000. Shows about how hard I drive this thing on a daily basis... staying away from 1000 lol.
I'm guessing the light would go away if you plugged it back in, but maybe you'd have to clear the code manually, I don't know.

It sounds sweet!!! lol.

I'm sure it goes without saying, but I'm assuming anyone that tries this knows what their doing, must be tuned, no DPF, watch EGT's, and lots of smoke will be bad. I'm sure eventually the turbo would get stuck if it wasn't worked for too long.

 

You have to clear it. It doesn't clear on its own.

 

That would make sense, you'd want that code stored, as it would indicate normally a failure of the VVT controller or system I suppose.

 

Most codes that I know of have to be cleared. Like the Low Fuel code.... Stays until cleared.

 

I totaly see where you are trying to get but dont you think a vendor or even ford would have figured this out?

 

Ford was forced into emission compliance, but I think the vendors should have figured this out. Like I said earlier; maybe part of the ECM programming was too hard to crack, or they figured it wasn't worth it? I don't know.

 

Parkland...can you goof with the VVT timing through your Tuner?

 

Pardon my ignorance but is the acronym VVT in our trucks the same as listed here?

Answered my own question... NO.

 

So I drove it to work like this, and spent some time on the highway.

At 100 KM/h, runs about 3 PSI, and 17-18 EBP.
At 110 km/h to 120, the turbo isn't as laggy, it is quite drivable.
I pulled a hill that I do every few weeks, at 120 km/h, at 10 PSI. That used to take 25 PSI and very simlilar EGT's, just shy of 1000.

EOT is 4-5 degrees from ECT, is used to be 8-10.
That tells me that less heat is getting into the engine.

According to the dash daq, it is taking less fuel to move
down the highway.

Now for the bad news:

cruise control won't work; although I suppose you could remove the linkage and leave it plugged in instead. To keep from triggering engine light and disabling cruise.

At lower speeds, like 80 - 100 km/h, it runs a little smokey. This is bad cause it will get in the oil eventually, and also black smoke = unused fuel, so it could be better yet on fuel.

Conclusion:

I think this could work great, with a shut down toggle, at highway speeds, just like that. At around 70 MPH, or 120 km/h, building boost isn't much of a problem.

The VVT system unhooked, leaves it wide open, and it works good starting at around 1900-2000 RPM's.
What would make this perfect, is if there was a simple way to actuate the VVT based on engine RPM. Someone help me think of something.

If we could find a simple way to actuate the VVT turbo just so it's trying a little harder to make boost, that would be a WICKED good mod, IMHO.
Just needs a little more that this. (10 speed shifter hooked via cable to VVT? lol)

 

No , I haven't seen or heard of anyone ever playing with VVT settings with a tuner.

Fleece has a standalone controller, so you can have a **** in the cab to adjust it, but it costs 600$, and doesn't work on our trucks that I'm aware of.
