GT28RS Should make a good 20+whp over the GT28R at the same boost. Cams are really needed for both turbos though.

couldnt do it, they didnt hook up the rev sensor. was a quickie freebie dyno cuz it was detonating slightly, the 310 curve was at 20psi the 308 was at 18psi. not much difference and much safer at 18psi

useless for you, very useful for me. besides you can figure it out using mph on the bottom graph. shows me peak HP and a very nice power curve. if you dont like the dyno oh well, its for me not for you. just wanted to share the HP #'s but all i get is a bunch of whining.

Its a very good dyno. The AFR is a little lean for me though. I like to stay around 11.3-11.5 for safety. Go for cams next. Some 256 would work really nice with the GT28R.

Tweak the fuel by increasing your fuel pressure some. Start with increasing 2psi and check the AFR. Increase a little more till you get the AFR you need.
