Ed,

Once again, thank you for the very detailed and in depth explanation. I dropped the block off today at Livernois Motorsports with an approximate 5 week wait time. I'm anxiously awaiting bore...

Looking into lateral gas ports in the piston or top ring.

I see Total seal offers gas ported rings now. Tech support recommended the gas ported rings over the gas ported pistons.

If I go this...

I'll be running Gibtec pistons this time around. I just measured all the bores in my replacement block. The largest cylinder is 0.0016" over the standard 3.552" bore size.

What size pistons should...

Took a look at my pistons today. Cylinders 2 & 4 had top ring land damage. https://uploads.tapatalk-cdn.com/20201201/fdf203a767ffc3689c62c0c62c2d4efb.jpg

Ed,

The total seal quickseat left a green hue on the cylinder walls, they were clean. The gaps were definitely .025"/.028"

One thing I did not do is oil the rings. That very well may be my...

Ed,

How would you say the Napier rings hold up under long term street duty? Comparing them to the standard second rings supplied by total seal in their AP ring packages.

Thanks,
Matt

Ed,

I did use total seal quickseat when building the engine. I agree with you, it is excellent stuff. This is my second engine I've had to rebuild due to cylinder wall issues. As you can imagine I...

Total seal AP rings have always been my go to ring package. I've been doing a bunch of reading and learned about the NPR gas-nitrided steel top rings and Napier second rings.

Sounds like...

I am switching to twin turbo so I removed the engine for the cam swap. Checking things over I noticed cylinder #4 was an oil burner. The engine has 1800 miles on it, mostly cruising, wot blast (25#...

Custom grind Comp cams for 4.6/5.4 2v TFS heads. Will also work with PI heads. Approx $1500 miles on them. Cams will be removed soon and pictures will be uploaded.

These cams are excellent for big...

Good info Ed. I haven't had any issues running 25-26# boost with the 2.9 Whipple setup on the street. I figured I would explore my options since the heads are coming off anyway. I guess I'll leave...

Ed,

What about putting stainless wire in the head and no grooves in the block. Only have the wire protrude .005" or so and seal against the MLS gasket?

I'm planning on staying with Factory or...

So I'm yanking my heads to have them checked over. Oil burner on cyl 4, buildup on back side of valve. 1800 miles only 1800 miles on them since being built fresh.

Educate me on low profile fire...

Ed,

Thanks for the clarification. I appreciate it.

Matt

I'm opening my engine up to swap camshafts now that I'm going twin turbo. My combo is a 2005 5.4 iron block, TFS 2v ported heads, 4R100 auto transmission. I've seen fully flanged bearing info on...

I'm hoping for a win win with this setup. Gen4 2.9 vs gen2 3.4

Less rotational mass, more efficient rotor design, better discharge. Hoping my IAT2 drop to prevent timing from being pulled. Running...

Response from whipple


All good. The is the rotor coating scraping each other. You will also hear it at start up once installed and takes about 300-400 miles of normal driving to wear in.*

We'll, sounds like we are on the same page Ed. I'll post Whipple's answer when I have one. [emoji106]

I've previously owned gen2 2.3 & 3.4 Whipple superchargers. Both spun quiet and smooth.

I have a brand new Gen4 2.9 right from Whipple. Just unboxed it.

Take a listen to this...

I've never had an issue with Ford phasers. I've done many of these trucks. Aftermarket units are junk. A little wobble won't hurt. Just make sure the reluctor tabs are nice and straight. Sometimes...

I experienced this "exact" issue when I had an -8an crossover on the front of the rails. Hard start, pressure bleedoff.

Since replumbing the system to my previous version (having the fuel pass...

Holy smokes Ed, you get the award for most detailed & accurate response. As always, you are right on point. Your knowledge truly is impressive.

I do have a Fore check valve plumbed into my supply...

Interesting video. I switched back to version D but added a y after the rails. This will allow one port to be fed from the rails, eliminating any possibility of flow differences into the regulator...

Well, that's interesting Jonathan. I haven't had any vapor lock concerns while driving "yet". I do have a cowl hood so maybe that helps with the heat. I'm actually planning on adding louvers to let...

Ed,

Open loop is also wot operation. I have ultimately decided that I'm chasing a ghost. I appreciate all you insight to this matter. Wot will be tuned off the leaner bank.

I read the deadhead...

Elmo,

Let me know if you need any other specific diagrams. Good luck getting you ride back together! Glad they tracked it down.

Matt

Ed,

What are your thoughts on my AFR variance being caused by cam timing?

My previous compression test yielded these results. Engine was cold, sat overnight, and blower was off. 800 miles on...

I smoked my intake and exhaust today. Didn't find any intake leaks. (Not surprised)

Exhaust:

I found a 1.5mm portion on an o2 bung I missed with the welder. Also found a pinhole on the other...

Radium said that the pulsing valve can be plumbed into a tee between rails on the balance hose without issue. It can also be placed before the y fitting on the inlet side of the rails. Sounds like...

Ed,

Check this out. Sounds like a nice product.

Ed,

X axis is time, correct. I have two 6an feeds coming your of my hat to a billet y-block. The y block has a 8an exit which runs to my filter and up to the engine.

What's killing me Ed is the fact that something changed a month ago, around 8-18.

Below are two afr logs.
Top log is from 8-8 and bottom log is from last night.

New wideband sensors netted the same results as before. Same AFR split, maybe a hair tighter. Putting my thinking cap on...

I suggest looking into a book written by Sean Hyland. He goes over the many aspects of these engines.
