Can shot peened LS rods hold 300hp?
any info would be apreciated.

I did a search and I couldnt find what I needed.

 

"SHOT PEENING is a method of cold working in which compressive stresses
are induced in the exposed surface layers of metallic objects by the
impingement of a stream of shot, directed at the metal surface at high
velocity and under controlled conditions. It differs from blast cleaning
in primary purpose and in the extent to which it is controlled to yield
accurate and reproducible results. Although shot peening cleans the
surface being peened, this function is incidental; the major purpose of
shot peening is to increase fatigue strength. The process has other
useful applications, such as relieving tensile stresses that contribute to
stress-corrosion cracking, forming and straightening of metal parts, and
testing the adhesion of silver plate on steel."

From: ASM Metals Handbook, eighth edition, volume 2, "Mechanical
Finishing, Shot Peening", page 398, first paragraph.

>> i know u didnt want a definition but i looked it up cuz i didnt know what it was

 

yes a stock ls rod will hold 300hp

 

Thanks for the info.

 

I shot peened mine. I kind of regret it now. If I were to do my motor again I would save for rods. If you get too boost happy shot peened rods can shatter.

 

My shot peened ls rods gave out at 267@ the wheels on me. So 300 is real close to the max. be careful

 

I believe most rods nowadays are shot peened from the factory. I even heard that Ford and Chevy shot peen their rods. This is from all information from respectable engine builder around my area....
