Tick and Loss of power

[U LOSE]

So I ran the car pretty hard Friday night. Accidentally hit the rev limiter a couple of times. The car was building 19 PSI now it will only hits about 15 and falls on its face somewhere around 4k RPM. I have also now heard a tick on two separate cold starts, sounds like it is relative to the RPM, so maybe the valve train. Runs normal other than that.

I just hope that it isn't a rod bearing causing the tick.

I'm a little worried about taking it to the dealer since it is modified. I don't want them to take it apart, then say we found the problem but we are not going to cover it so its going to cost you 1 million dollars to put it back together now.

I haven't actually popped the hood and listen to the tick. Just heard it with the window down and driving. Next time i hear it I am going to try and investigate better.

Gotta pay to play!

Good luck with the fix

I'll pay if i have to.

Grab a video of the tick and post it. My motor also has a ticking sound but thus far runs strong, but it's also a stock motored car minus a Ford resonator delete.
In my opinion if you're down on boost it's escaping from somewhere perhaps an exhaust valve as boost is only a relative measure of back pressure. Run a compression test and leak the motor down if you can to see how healthy it looks.

I'd start with pulling the plugs, draining/inspecting the oil; then a compression test, then scope the bores.

Take it back to the dealership you bought it from, I'm assuming it's a ford dealer, if they give you any crap about it being modified, tell them you sold it to me this way.

Yeah i'm going to try and start on that today.

I would but that dealer is about 5 hours away. it is In Louisiana, and im in Houston. The dealer that i bought it from said the car is under warranty and I will have no problem with the after market exhaust and CAI. That is all they thought the car had.

I was going to grab a video this morning on my way to work, but i could barely hear any ticks. The only faint sound i did hear sounded like it might just be something loose under the car, maybe exhaust or something.

What does yalls cars idle at in vacuum? inHg. Trying to figure out if maybe i have a vacuum leak.

Thanks,

 

[U LOSE]

Never mind idles at 20-21 inHg. Right around where it should from my research. Maybe its the supercharger bypass system.

Sounds about right. Mines at 24.

Do you still run cats?

Well still trying to figure out this problem. So far I have changed the plugs, and I have changed the bypass valve actuator. Thinking maybe the diaphragm was messed up. But it wasn't. So now i'm thinking that the computer is limiting me somehow. I'm 99% sure that the tick i had was coming from a bad idler pulley. The engines runs perfectly quite now.

Yes still have cats.

I only have HP Tuner from my GM days. So i tried to data log it and see what was going on. I notice that Knock Retart goes off really high. But in a negative number, and only in that one time slot, which is weird, could just be HPTuners lack of Ford support. I also noticed that "Torque Source" pretty much stays at Driver Dem. Which i "think" is normal. I was hoping that "Torque Source" would shed some light on some things. Maybe "Torque Source" isn't working right because once again I am using HPTuners. But i did see it change at one point to TipIn so that kinda makes me think that it might be working.

 

[2011 gtcs]

You might want to buy a SCT X4 and get Lund tune, so if there really is a problem you can data log it and send it back to him. I will say your problem is a little odd

 

[U LOSE]

yeah i'v been thinking about getting an X4 for data logging. Someone said that on a 5.0 when the KR goes negative it is adding timing instead of subtracting. Makes sense.

 

[U LOSE]

In that pic above I am flooring it with traction control off, and the TPS says 56%, so for some reason the computer is not letting the TB open all the way, just have to figure out why.

Made this video on the way home. I was floored and only saw 13 psi.

With your gas light on I wouldn't be going wide open. Not good at all.
