I have looked into alot of the 6.0l n/a and boosted engines but from looking at this article and foose04 wats the point of goin bigger motor when u can just up the boost on a 4.8l. Im not gonna be goin crazy on my build but with my mp76 ported heads and boost cam I sure hope to get to a 500rwhp mark.

 

Higher octane doesn't have more energy. It just releases it slower for a longer and more controlled burn.

 

I have doubts it could ever make a 1/4 mile pass. Impressive, although.

 

you can make 500rwhp fairly easy on 10psi with the 4.8 and unported heads

 

I think thats how they keep the motor together! Remember, torque is what kills all things mechanical on a vehicle... You get a 112 with big duration like that cam, even on boost, its gonna be all high rpm power, if they would have tried to make 1200 hp at 5000 rpm, it would have bent every single rod. A 112 LSA would have let alot of boost by in the low RPM resulting in alot less cylinder pressures and low end torque, but thats fine cause thats not where the HP is at anyways, its up top. They never even did mention what the torque was, prob because it wasnt very good. Another way to think about it is look at all them ricers with them little 1.6-2.x engines making 600-1000 rwhp, you can make ALOT of HP from small displacement if the torque is kept down. Just my $.02

 

For me the 110~112 lsa's have always made more power NA, turbocharged, and supercharged.

 

hey let me know when you go turbo, ill take out a loan and we can both build a kick *** setup lol.


hopefully GM is reading that article and throws some turbo's on a forged internal 4.8 that makes 500hp and offers it as a stock alternative with the 6.2 in their trucks lol.

 

Just my opinion but id think you would toss a rod with 27lbs of boost at 7500rpm easier then you would at mid rpm range

 

When you toss a rod, it usually happens during the exhaust stroke, because there is next to no pressure pushing on the top of the piston. the piston peaks, wants to keep going. This could result in rod bolts snapping or wrist pins ripping right out of the pistons. With a high boosted application, there is a whole shitton of exhaust to get rid of, so there is more pressure atop the piston during the exhaust stroke, keeping this condition less severe.

 

so you would be less likely to throw a rod due to high rpm.
