if ess offers a kit capable of 775 hp on an 08 or an 09 with the original rod bearings,the motor must be pretty sound
The 2 kits without the disclaimer are rated for less than 600 HP; it also says no where
on the ESS website that the kits are rated up to 775 (that's what the V3 Si supercharger is maxed out at). The 625 & 650 both have that disclaimer, which makes perfect sense since those kits are placing a higher demand/stress on the engine with increased supercharger psi & more aggressive tuning.
So for you to say ESS offers a kit capable of 775 on an '08/'09 with the original
bearings, is INCREDIBLY misleading
. Also, if you're gonna go LC & replace/upgrade the internals, what makes you think that the OEM bearings aren't gonna be replaced
