Did not read the whole thread here so asking, did anyone mention about the ARP wave-loc rod bolts ? They have 2 different series of wave - loc rod bolts. High performance and the Pro series. Also ARP recommends the up most importance of proper rod bolt stretch and torque installation no matter what rod bolt you are using.

Also a side note: no hydrogen embrittlement can not take place without tensile stress. ARP limits the factor of HE by employing a baking process that purges hydrogen gas from the steel. just some short info. I have studied HE a bit as well. Mercury with the bolts on their Verado outboards was or still is having problems with this issue but no one wants to listen to me about it as I had told some of the OEM dealers to get ahold of ARP and have them provide the bolts instead of ordering back thru Merc for the problem solving..

Also oil pressure and or any pressure is just a measurement form of resistance. A lot of people think that higher oil pressure is better. I learned thru David Vizard about 25 years ago this is not the case. Too much oil pressure causes the oil pump to cavitate and can actually slow down oil flow movement. FWIW.

I'm a fan of the Schumann oil pumps as well and been using them for years. They also are incorporating some better ideas for the LS oil pumps. A lot of people do not know who they are but they have been in the oil pump ballgame for a long while.

I see you are supporting the crowd that laughs at you constantly... we have plenty of water here, that's California pal. Another overnight engine builder I see... Next thing will be Budman II posting unattainable women avatar.....

Ok enough messin with Dans thread, back to regularly scheduled content! You can PM me if you would like to go rounds.

Sounds like Mark answered my question before I posted it. Mark, looks like your ESP is in sharp focus today!

Easy Borg, just kidding with you. I don't take myself too seriously, so I can handle it when someone busts my ballz a little. And I'm too old to be chasing after unattainable women - they tend to be even more expensive than these damned boats.

I have no idea, of what type engineers you work with, maybe the electrical field is different. One of my close friends is an engineer, that not only designs production plants; he actually is on- site when the plant and it's systems are being put into place. Believe it or not, he actually can design his own boat parts, make them and install them.All the engineers I have worked with in this industry, know; what they are talking about. As far; as the engineers at Callies, I know for sure the engineer; I know there has forgotten more than most of us know about crankshaft and rod design. That engineer and his son also own Shaftech LTD, best place to send a crankshaft for repairs.

Sorry I am way behind on this thread. I write and ten more posts show up before I am done.

Anyways STRAIGHT from ARP. in my notes and I will quote them (ARP).

L-19 is a premium steel that is processed to deliver superior strength and fatigue properties. L 19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering a clamp load at 260,000 psi. Uses in Short track and drag racing apps where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels L-19 requires SPECIAL CARE during manufacturing to avoid hydrogen embrittlement. The material is easily contaminated and subjected to stress corrosion. It must kept very well oiled and never exposed to any form of moisture.

More from ARP - materials used in the manu of cap screw type connecting rod bolts.

8740 crome moly
Aermet
ARP2000
L19
Inconel 718
ARP 3.5 (AMS5844)
Custom Age 625 plus

and they list them in that order.

ARP2000 is an alloy steel that can be safely heat treated to a higher level. Producing a greater strength material than 8740. Arp 2000 and 8740 share similar characterisitics - ARP 2000 is capable of achieving a clamp load at 220,000 psi. ARP2000 is widely used in short track and drag racing as an upgrade from 8740 chrome moly in both steel and aluminum connecting rods. Stress corrosion and hydrogen embrittlement are typically not a problem providing care is taken during installation.

A SIDE NOTE :

Metallurgy for the non engineer. Getting toughness vs. brittleness, with steels as the strength goes up the toughness decreases. At too high a strength the metal tends to be brittle. And threads accentuate the brittleness. A tool steel which can be heat treated to 350,000 psi would be a disaster as a rod bolt because of the threads,

I`m an HVAC guy. This means I know nothing about motors.
If I was a fireman like Borgie, I would understand motors.
I was wrong about the L-19 bolts, they are great for a 600 hp motor and marine application where moisture isn`t an issue.
My wife is ugly and I only post unattainable women in my avatar.

Now that we have that cleared up, I only have a few pictures of this little hottie I got with in Arizona, she was tired of her boyfriend with a little pecker always trying to tell her how smart he was or something.. I wasn`t listening.




Hooters waitress of the year!

I think you posted a pic of your wife or girl friend with Bob Teague already

Sounds like the women in Ohio are just like the 1's in Maryland
