I went to the dyno for the first time since stock turbos, did a base boost 13psi pull and then some 17 psi pulls, will go back later to do some higher boost pulls. Though i'd share, mods in profile. Note the GMS 550 ballbearing was kinda a crappy turbo, its a gt2560r but with a stock z32 compressor housing honed to fit over the 2560r compressor blade. Which makes the a/r pretty tight and restrictive, I believe.
we did many
