I've been searching for hours now, trying to see what people are using for twin turbos on stock 346's with 317 heads looking for street car and 650 rwhp. I'm currently running a .84 p-trim t-70 single rear mount and want to do a twin front mount. It looks like most are running a stage III t3 wheel 2.229-2.559" or T4 small shaft "o" trim 2.296-2.922" or the "p" trim 2.544 2.922, with anywhere from a .48 a/r to a .96 a/r. Just wanted to see what anyone else was running and how they liked it?

I guess nobody has twins! I think I found the turbo's I might use. They are 57mm with "O" trim .70 a/r turbines I know they may seem a little small but on the compressor map 2 of these should be perfect.

my old twins were T66 with a p-trim on center T4 .69AR

171 MPH at 3200 lbs with a 346 cu in solid roller with 317 heads.

650 rwhp is easy

my setup is on a 427, but Iam running twin T3 .63 P-trim wheels

Here you go. Just posted. Give them a call. They'll set you up. I personally like the 70's at 93lb/min. Should give you plenty of growing room. makes me want twins.
