Just had saleen stage2 kit (Brenspeed) put on my car with 29000 on it. Runs great. 426RWHP/409T on dynojet.
The term "powdered rods" - I work fora company that makes powdered metal forming machines. The term powdered rods comes from the process in which the rods were made. Quite literally very a fine powdered metal mixture is forced into a mold whic his then compressed together at a very high pressure (as high as 2000 ton psi). When the mold is opened the rod (or part) is ejected from the mold but holds its shape, in some instances in this state the latent part if dropped will crumble. The part then goes through a veru hig temperature cintering (heat) process through an oven at temps well above 2500 deg F. This process molecularly bonds the powder together forming a solid part. A final "re-striking process" (just like when they strike a coin at the mint) will be performed on the part which insures part shape and accuracy. Any final processing will take place thereafter such as machining. Piston rods along with timing gears are some of the more common parts that use this process. This is the basic process in simple form.
Forging is much superior and I am sure that we are all more aware of how the forging process w/o details. Hope this helps you out. The GT500 5.4 uses forged piston rods and is capable of handling much higher boost levels.
