what to use for Twins.... Just wondering what turbos you guys think I should use for twin setup? My plan is to make 600+ on pump and then run race gas and really hit the sweet spot for the turbo's. What would you guys use???
i think t60's would be to big for 600rwhp. i like the twin 57mm's HP uses in their kits. check out some of the cars. their making 800+ on the twim 57's.

i got a vette mag. and they dyno a 02 zo6 stock and it makes 356/331 and then they install a HP twin 57mm turbos, a tad over 7 psi and they make 551/529. at 3200rpm the vette was making 400ft/lb rwtq. i think thats great for the street.

When people like HP say twin 57mm turbos what they actually mean are T3/TO4E 57-trim turbochargers, which just happen to have a roughly 56mm inducer. T3/TO4E 57-trim's and T3/TO4E 60-trim's will support basically the same amount of power, with the right turbine wheels they will make roughly 450-500 RWHP each.

Pretty much any mid sized set of twins will do 600 RWHP on pump gas on an LS1 without breaking a sweat, but you gotta set a real top end goal to know what you need.
