Are the F1 Engine Manufactures using I or H beam Connecting Rods also are the caps cracked as in a Two stroke engine ?
thanks!
thanks!

Hello,
I guess an I beam or an H beam is all in how you tilt your head, isn't it? What do you mean by cracked caps?

This one is out of a Ferrari F1 engine. Not new of course but not too old either, late 90's.
I know old 1992 Honda F1 engines had hollow con-rods to save weight.
Mitsubishi EVO-VII street cars have hollow cam shafts for the same reason.

H. Eckener,
I beam and H beam connecting rods are not the same. The one shown below is an I beam, while an H beam would have the "top" and "bottom" of the middle section hollowed out with a solid "front" and "back".
Regarding cracked caps, this is a procedure in which the "big end" of the rod is formed as one piece, but then split by inserting two half-moon shaped tools and expanding them until the rod fractures. This produces the most accurate mating surfaces when they are connected to each other after enclosing the crankshaft. Although I have no direct knowledge for Formula One rods, fracture split rods are very common in the road vehicle market, so I assume this process is used for F1 also.

In addition to what Cory states, let me add this re : cracked caps.
Powdered metal rods are used in many of the newer O.E. motors in passenger cars and trucks. This technology grew in that it provides a lower cost (cheaper) method of producing connecting rods. Considerably less machining in required. Strength is supposedy equal to a good forged two piece rod. PM rods lend themselves very well to the cracked cap system of manufacturing, thus all PM rods are pressed one pice then the caps are cracked to make them two piece.
