Blaast Performance K04 rated for 345 whp?

[rasild]

Has anyone had any experience with Blaast Performance turbos? They claim their stage 2 K04 can produce 325whp@22 psi and 345whp @25psi; I find those number hard to believe.

From their listing:
Compressor impeller 45.1 X 59 mm
Turbine impeller 44.5 X 50mm.

I could not find much information on their turbos and their stage 2 K04 is almost $900, just as much as a Borge Warner k04. I will probably with the proven GTRS, but wanted to see if there any other options out there.

when you look up "blaast performance", the second post is BEWARE OF BLAAST PERFORMANCE. granted it's for a turbo rebuild situation, but I read the whole thread and yeah I wouldn't do business with them.

The comp and turbine are in between a FrankenTurbo and GTRS, so I would assume the power output would fall somewhere in the middle. But I have no idea.
