And your powerstroke turbo is on the small side for a high CR 450HP engine.
Better off with N2O on this setup.

that comp is perfect for e85. 10-15 psi would be easy 6-700 hp with the right turbo. im not familiar with that particular turbo tho. i would highly reccomend forged pistons tho...

I wouldn't be afraid of that turbo on a stockish 350, that is probably going to be off the map without any trouble though on your built engine. Find something T6 based like a TV7/8 series, GT42, Holset HX50+ etc.
When people refer to the "size" of a turbo they are referring to the small diameter on a compressor usually. That is actually a 58mm or so head unit but the exducer is 80mm. Garrett did that for marketing on the GT series stuff which is REALLY annoying.
Use good gas or E85 and I could see low 10s into the 9s in your future without a ton of trouble.
