Owner of Z1 is making over 1000rwhp on the VG30. I don’t know anything about the LS6 but the VG is plenty stout ---

I will say this… The VG motors can hold their own considering they are not forged internals… but i do agree an LSx motor can hold a lot more. Ned, im not saying you have to go forged, IM just saying you could make your goal on your N/A motor but youd have to be a little more cautious ---

ok i havent read the entire thread but i was running 10-12 psi on my 10.5.1 vr daily. but thats all i would push through it. any more than that even on the forged internals of the vr6 and dropping the compression is highly recomended. imo unless you plan on running higher octane then all numbers change. ---

I have seen ls6 blocks take a lot of abuse though, just feel that theres better parts in an ls6 than his motor the extra displacement sure spreads the stress out more. and it takes less boost to make the high power. anything when exposed to less stress will perform at that level more safely and for a longer period. ---
