Eagle crankshafts and ESP armor finish

[biomedtechguy]

I used their H-beam rods in the 421 Pontiac rebuild for my wife's GTO.
I buy into the ESP armor treatment.
Anyone here have an Eagle crankshaft with ESP armor and what are your experiences. If not your own experience, what do you think about it? Check it out:

In my current build I have an Eagle forged crankshaft in it. Happy as can be. Just make sure if you have a 4 speed it is drilled properly. If you run the newer roller bearing versus the pilot bushing which entails cutting the shaft on the four speed. Then they are drilled deep enough from Eagle. Still check....

Have a 4.5” eagle crank In my 535, I dont believe it is coated but I’m going to ask my builder. I do find it hard to believe they picked up 40hp with a coating but who knows.

Interesting. Makes sense and looks very affordable. Shipping may cost more than the service.

Not a coating, but it's a finishing process that neither adds nor removes any material.
From reading their independent dyno results it looks like no less than 4%, so let's use that number.
In my case 4% of 600 is 24 horsepower, and there are other advantages as well.
I'm all in! I'm going to have them do my crankshaft, and if they have the rods I need I'll have them do them too.

Might as well give it a shot!

Thanks.
I use a bushing with my billet steel flywheel I got from Brewer's Performance. I have the Passon a855 installed.
I have a couple of questions:
Are you saying the depth of the Eagle crankshaft should be checked to accommodate a bearing or a bushing or both?
2nd ?: I like the idea of a pilot bearing better than a bushing, and I have to replace my broken assed McLeod pressure plate on my current motor (stock crank). Is there some special process that has to be done to accommodate the bearing?

Mine required no prep. Brewers cut the shaft on my trans when they rebuilt the trans and check the taper on the shaft for distance.

When you buy the pilot bearing it comes with detailed instructions to do it at home.

In my build thread here there are pictures of that...

No way any coating is worth 4%. If it was every engine on the planet would be using it. I can tell I coated rod and mains this time. Did zero for power.

What brand of crank and rods? What was the "coating"? Was it Eagle?

 

[biomedtechguy]

Here is the dyno sheet from a Hot Rod magazine test of a SB Chebby. Only difference between the 2 runs was ESP armor on the crankshaft.

Am I looking at that right? Did they lose power with the armor?

The upper lines are with the Armour....

When I got my Eagle crank this wasn't available...What is the cost of that option?

 

[1967coronet440]

Guess I should’ve looked at it better haha

Happens when your already 3 beers in at 8am...lol

Good thing the Eagles crank isn’t coated but it is a finishing process.

You coated the mains and rods?
Main what? I’m missing something.
How much power was/is your build?

Check out the link in my 1st post.
$240 for a crankshaft, $114 for 8 rods. I'm doing it. At the very least my engine assembly documentation pix will look really nice. Lol
ESP increased the amount of time for the oil temp of the engine on the dyno to rise to operating temperature so much so they put a small load on the engine to raise the oil temp so they could get on with the pull. THAT alone should tell you it works!

I was just curious....If it was offered at the time I would have done it on the crank. In the end what do you lose other than some $$ all effort is to limit parasitic loss...

Over on FABO, member RAMM loves the coating. At one of the local speed shops that regularly build hot stuff, the cranks are in the show case well advertised. They look really cool and weird at the same time. I thought it was wall art in the show case being it looks like a chromed crank until you look at it with the advertisements about it.
