LS1 190mph and 480 RWHP

[Snorman]

Maybe he's is running more displacement. In any case, you've seen the dyno sheet and know the guy...so you'd know more than I do about the car. I think the next evolution with the LS1's is going to be a big move to larger displacement short blocks. A year or two ago, these were very cost prohibitive, now companies like ARE and MTI offer up a pretty good selection from 360-427 cubic inches.
Just when I thought the LS1 cars had "topped out" a year or two ago, they kept going. They are certainly an impressive motor. Amazingly, many of the older head/cam cars are still running fine with over 50k miles on the combos. That's a testament to the durability and performance of the LS1.
I don't know anybody, nor have I heard of a 331/347 making >480rwhp NA, but I suppose it could happen.
Later.
