 Shoot; even though Magnusun doesn't make the blower for either the LSA or LS9 I think I still may have some validity: The LSA uses the 1900 blower and Magnusun rates the same size 4-lobe blower to something like 800 horsepower (I haven't read what's claimed for the 2300 in the ZR1). My point is that I think that ZR1 could reliably live in the range gtahvit said. I know the engineers said that the LS9 is at it's limit now but I don't recall exactly as a result of what. It has a completely forged bottom end, bigger head bolts, stronger heads, and a load of other stuff. I'm sure adding long tubes, a different pulley, CAI and catback would get another easy 'hundred horse' out of it. Still, the point about adding FI to the Viper would just be stupid-power, but I don't think a comparison between an NA motor to an FI motor is quite representative.
Either way, it looks like Dodge may have underrated the car a little  |
So the boy's at GM have even said that the LS9 has peaked...Well wouldn't that end the arguement?
I see what has been said about high compression ratio but it could still handle some boost, you said so your self... And in an earlier post I did say it would be "stupid power"
So it does prolly go back to "No replacement for displacement"...
