What kind of numbers have you seen a 1J put out with BPU?

Should be around 270-300rwhp. I did close to that with FMIC, 3" exhaust,1 walbro at 10psi I think.

depends on what you call BPU.

Thanks for the replies. Have another question.

What's the most boost stocks twins can hadle? I read in a few places that anything over 14psi is a ticking time bomb, but I have also seen many 1jz owners boost way past that, so any real world experience?

I did 313/320 on 15 psi, untuned. I'm sure I could get around 350 with a decent tune, the engine is pretty potent.
