BME rods use a higher grade material than 7075 iirc. Have they ever released the material specifications for their aluminum rods? I think I have seen some of that aluminum at my work for a Boeing project but I never payed much attention to it.

 

What are the benefits of running these rods compared to the other aftermarket rods?

 

There are 2 benefits.

#1 they are lighter so with less rotational mass they will accelerate faster (read worth some hp) and reduce stress to the rotating assembly at high rpm.

#2 In our experience high hp cars (over 600) develop a taste for rod bearings really fast. While the reasons may be numerous and some bearings may work better, for any amount reliability (this is still relative) the aluminum rods reduce the shock loads to the bearings.

 

Here are some close ups of the 150mm (162 is the same) rod pictured above.

Enjoy









I tried to capture it in the picture but where the rod cap joins the rod it is serated and not flat with pins like other aluminum rods. This allows for more surface area and therefore more clamping force at a given torque level and more points to center the rod cap. That is the L19 rod bolt hardware that we use pictured as well.

 

Mmmmm...CircleLoc™


Yummy

 

They are assymetrical too...goes on one way and one way only

 

Very nice, Im getting a little jealous haha. Im running groden rods at the moment.

 

Would you say this rod is more suitable for drag racing?

 

Just like Mercedes Benz rod ends.

 

I am going to road race mine, Lucas street drives and drag races his, and the 1G is a pure drag car. They have worked in whatever they have been asked to do so far.

 

How much of a weight savings is there with these rods?

Wow, that a big difference. Usually weight differences are in grams, not pounds. Hopefully they keep holding up well!

 

MGP was close though. LOL. Actually i believe the maker of these rods was partners with who now runs MGP. They broke up after a big dispute. I wont let the cat out of the bag but lets just say there are two companies i believe that run the CircleLoc setup. Both say they have patents on it but hard to do when they were partners when they created it.

Anyway great looking rods got a set myself for another engine i was thinking about building.

Interesting read about connecting rods in general but there is direct application to the subject at hand:
