Connecting Rods?
What is the strongest material for con. rods? Hot Rod magazine has made me believe that CNC'd forged steel is the best, is this right?

Titanium is just below them in strength properties but are much lighter. A comparable 6.0" titanium rod will weigh in at about 500 grams and about $3500.00 a set.
How fast do you want to go? :steering: :lolg:
CNC'ing has nothing to do with strength, only keeping tolerances closer for better quality.

Are they machined from a block of forged steel or forged into the shape of a con rod, then machine finished? (the latter is stronger according to Hot Rod) http://www.hotrod.com/techarticles/82378/

Olivers are billet(single block of steel), Carrillos ar forgings. Both have advantages and disadvantages but either will run 9500 RPM all day without a problem.
PS: Your artical is wrong in saying that titanium rods are used in 9000 RPM Nascar motors. Titanium rods are not legal in Nascar but both Oliver and Carrillos are used extensively.
