My thoughts exactly. I ran an S258 in the .70 open T3 and made 479whp on straight pump and stock engine, saw 28psi by 5k. A friend's S362 setup with a JMF divided T3 mani and .85 hotside saw 35psi by 4800 and made 708whp on E85. Another friend's S362 with the .76 divided hotside sees 25psi under 4k, hasn't cranked it up yet though.
I had some exceptional results in both the BEP DSM bolt on housing and the bigger BW twinscroll T3 housing.
S259ETT in the big Twinscroll T3 with a set of factory freak Graveyard Motorsports cams. Jon told me the set I received were the first made of the 274s, but the measurements my machinist pulled from them are far bigger than advertised.
With Snow Performance meth kit saw full boost 37-38psi around 4600rpm in third in cold weather.
Link saw 63+lbs/min routinely.
This was with the larger 74mm turbine.
