Another dyno for the mix
S14 sr20, oem piston, tubular tomei T-25 manifold, gt2871r 64a/r, tomei 256,
approx 16-18psi, pump gas 93
I think the curve the op posted looks fine for what it is.
------------------------------
FWIW this is my favorite cheap ($450~) top-mount T3 turbo for daily driver sr20det engines (50 trim compressor, T3 48 a/r turbine). This 9:1 compression, 93 octane, crappy exhaust manifold (worst one I ever saw, custom junk), Ebay intercooler, brian crower 264's, just a bunch of junk and it was absolutely a blast. Top curve was 18-19psi.
