Interesting Finds At PRI 2024

[kidturbo]

Had a great time at PRI this year. Always a good spot to meet up with old friends from around the country.

Plenty of cool diesel tech, and even a few Duramax advancements caught my eye. Would like to hear more about these rockers and bridges if anyone has data.



Please feel free to share all the other cool engine hardware I walked past.

Wow. A set of those will set you back nearly $5k. How much more can you get for that much money? I'm thinking there are better places to invest that much in

That's enough data for me.. lol.

Here is their big valve offset heads with dual ratio config that fits a stock SB block / lifter which caught my attention. Actually it was the "Patent Pending" sticker, but still, some nice engineering work.



Speaking of data, I did talk with the guys from Callies for a bit. Next batch of Duramax Ultra Billet's be rolling out of the furnace next month. Said sales have been steady, with a fair amount of those going neutral balanced. Confirmed the neutral options with sales report from the FD team. Saying that first batch of balancers done gone, and they were built for one crank.. No reported issues from that side beyond some over treated washer which got caught early on. Callies had couple other tungsten laden cranks on display, but no shinny Duramax.

If you already have 50-75k in what's another 5k? I see this as a 6000 RPM dmax or stupid 3 figured boost application

Was Brian Tooley there? I saw he was about to release a canted valve head for the LS platform

I was most interested in the 6000rpm geometry aspect of those rocker / bridges. Since can still count on one hand the people actually spinning a Duramax at or above 6k, would like to see some hidden camera action on a side by side comparison. OEM layout not shown any extra wear in my abuse. Maybe some quicker revs, and reliability in high spring rate applications.

No idea on Tooley. Every other booth there was LS .....

More importantly @kidturbo

Did you catch the PRI flu that’s been going around while there?

He was. Erick Weingarten and Powel machine confirmed on Youtube.

The Manton Dmax stuff is not new. It's been out for a while. https://mantonpushrods.com/product-category/manton-diesel-products/duramax/

They Private label the spring kits, pushrods, and billet bridges for XDP.
They also offer an upgraded shaft that is supposed to keep the lube flowing when the rocker arm opens. Apparently the OE design shuts it off.

No, but like all the other patrons, I donated my $40 to feed a congressman.. Actually paid for a buddies pass, so I bought two lunches... Hopefully one of those mofo's choke on it since the RPM act has proven to be no more than some lobbyist lunch money fund....

But but but... the Coyote is king! 2500hp on a stock block

It was good to hang out with you in person again old friend! For what it is worth we are running Wagler billet bridges in Paul's motor with stock rockers and zero issues and spin up to 7200rpms on it. The Mantons are nice but I don't see the value in them honestly.

I can't say I've been to that high of RPM but I've done around 5500-5700 during driveline failures and flared shifts with my old engine pulling. Similar config (stock bridges in that one too at that point).
