That is rather vague statement, because it could be a turbo engine or another type of supercharger. Here is a thread on the powder metal rods, and how much horsepower they can handle. http://speedtalk.com/forum/viewtopic.php?p=206633 looks to be around 570 HP on stock powder metal rods. I saw another thread on Howard Powder metal rods, and they are good to around 800 HP. This article here talks about the components inside the LS engines. http://www.motor.com/magazine/pdfs/102010_07.pdf "All OE LS pistons are hypereutectic cast type (alloy with high silica content),
except for the LS9 piston, which is a forged aluminum piston (required to handle the higher cylinder pressures associated with supercharging/forced induction)." I haven't even gone into the block or crank.
The Harrop TVS2300 and Magnacharger can go 15 psi. |
