LS1 346 ci milestone: 516 rwhp
 

This is using a custom intake, stock ported heads and solid roller cam setup.

First one above 500 rwhp all motor no nitrous ot forced induction.346 ci ls1 516 rwhp

Wow that is a lot of power out of the stock displacement.

good god, that's amazing. I'll have a re-enlistment bonus coming up pretty soon, that's a good way to spend it:)

I cant wait for a LSX intake, Head/Hyd. Cam, Exhaust car to hit the 500 rwhp mark.

Cartek has almost done it.

Good news here!

next goal 600rwhp? :)

ls1 is awesome. can you imagine a hand ported AFR head with lsx intake? ofcourse we are getting farther away from what an ls1 really originally was. still amazing. alan futral is sick!

I cant wait to see what a good set of AFRs and the LSX intake would do :D

Very Amazing..

Must give credit when credit is due, very sweet !
