If it makes the same power at 1.0 bar as the GT at 0.8, it should be fine and so will the 915.

FYI, going from 1.0 bar to 1.4 bar on my Holset HX40 did not raise the outlet temps at all from what I can tell from datalogs. I was quite surprised and pleased this occurred.
Alright, but what does this say?
I need more boost for the same power?
I still need to plumb up my boost controller before I can try more boost.
Also, I found why I have no boost right's the wastgate on the holset, It's not staying closed with my welds....
I'll re-weld tonight if I have time and report back.
Compare this run to the one last night in the second video. There are diffrences in sound(sorry I didn't catch the gauges) and performance.
Turbo powa!
1977 911s. it's cool
