Im sorry, but there is no way the GT3582R (a.k.a. GT35/40) turbo is a 700hp turbo.... The 82mm compressor used in it is only capabile of 60lbs/in which is about 580 to 590 hp....
Here is the map of that compressor
Here is the 5.7L at 600hp as a twin setup.. (would work but not to well as the efficiency is not optimum around peek torque so there is an increase likely hood of detonation)
Here is is as a single on the 5.7L (deffinitly not going to work)
Upping the anti and bigger engine.. Two of them with smaller A.R would be even better ..
A single Borg Warner S380 / Garrett T04Z would be another with T4 sized housings..
PSI.. Great putting up maps..Good..
Thier claim works out to around a 600hp engine too. They claim 392 RWKW which works out to about 520 to 525 RWHP that that works out to about 600HP which again is what the turbo is maxed out at. Also they claim that this is at 24psi which is a 2.63 pressure ratio which is right on part with there pressure ratio area that the GT35/40 can supply 60lbs/min....
I agree any engine bigger would be hard to get massive gains..It's only a T3 exh housing after all..
They actually fit these to Gen lll 5.7 Chevies with modest results.. A GT42 would be a better choice..
In any case it depends on your power goals?? A GT3540 would still make enough to blow a std 1UZ assembly...
