more pics,didn't get one of the supercharger

They appear splayed inward......aimed inwards,
towards the pin.

David,
They are both manufactured by Manley.

JT, you are correct. With the bolts splayed the stress is now distributed up the beam of the rod.

Chris,if you don't need brgs why are they pinned for them? Did you ever see the crankshafts that came out about 15 or 20 years ago made out of a composition material (it was kevlar or carbon fiber or something like it),they said they tested it with no rod brgs or mn brgs but i never seen or heard about it again.If you zoom in on this rod you can see the tapered small end,in your opinion do you think it was to help oil get to pin or what?Just curious what your opinion is,thanks,Smitty

Smitty,
These in the pic have pins for the old school guys. Sometimes with new technology you have to take baby steps, so Jagers rods can run either way. Due to the lubricity that the surface has bearing clearance of .0005" can be run on rod journals. Before the nay sayers start, these rods were outlawed in NHRA where they were being run in Pro Stock very, very, very successfully. The actual rods in the Pro Stock engines I saw had 150 passes on them and all rods as far as stretch goes were within .0001" of spec.

Pin bores in the pistons in Cup cars and other high rpm engine applications are oblong horizontally. What has been found is the pin bore if left perfectly round distorts due to the higher rpm and the loads that are put on the pin support area. Pin flex is also an area they have been working on. It would be my guess the beveled little end has something to do with pin flex and reducing it during high rpm.

Smitty,good way to take some weight out of the reciprocating piston end. Most of the pin load is down where this pin end journal is still bigger. Chris, interesting idea there on those rod bolts, angled off the vertical axis. Guess this would possibly add strength by shifting the axis loading?What is the idea on the bearings, I assume some sort of material treatment on the surface or coating?

I love this out of the box rocket science stuff!

maybe this was one of the motors drom the 300 hr durability testing,the machinist who had it told me he thougth it was ran at 100 hours at wot,but maybe it was 300. The mains in block were tore up a little(in the saddles)caps didn't look like they walked though but rest of the parts looked new,Smitty
