Turbo Comparisons
Just for general interest, I figured that I'd post dyno charts of three turbos for comparison:
1) TD04-15G (GReddy turbo) on a 1.6 at 8-9psi
2) T3 Super 60 on a 1.6 at 9psi with boost control issues
(hence the dip in torque)
3) GT2554 on a 1.8 at 8psi with fuel issues at the time (again accounting for the dip in torque)
First graph is just HP showing very similar results.
Second graph shows torque.
Interesting how similar the GReddy and T3 super 60 really is (as already pointed out by braineack).
You can really see where the 0.2L of extra displacement + smaller turbo really helps that GT2554 spool and create lots of torque early on.
Funny how we all have little snafus right around 4k rpm.

yeah, once it fully spools it takes off, I'm sure 15psi on that thing would make some great numbers.
The curve on the GT255 looks promising, I bet it's fun with all that low end.

I was using an EBC that didn't want to work right on the dyno, it kept spiking, dropping and then holding (I wasn't smart enough to throw the MBC back on real fast). I plan to be back on the dyno within two weeks.
That and I was making 170/145 at 6psi.
