I was looking at the various turbos today, and the T3 off of my SPG looks a LOT bigger than the TD04 off of a viggen.
Now, looking at compressor maps, it looks like the T3 is a more capable turbo that will flow more air and make more power. Am I reading these maps right?

I case you did not notice the x-axis is does not have the same unit in these maps, ie. the 15 is not lb/min divided by 100... Could be kg/s which add upp to real life values (210-220g/s). 0.2kg/s = 210g/s =27.8lb/min.
A plain T3 I would not go with, but a T3/T4 hybrid is good ~400bhp.
My feelings exactly! A 60+ trim t3/t4 has been something i have asked about as well. They are fairly cheap and would make good power in the mid/high range.
I'm not sure how much difference it makes but those maps are for a 15g, and the viggen/aero turbos are 15t, yeah? I have ridden in a 9000 with the old t3 on it and it spooled up slower than dick. Yes, slower than that. Something to consider.
You're not talking about the same Units though. One is in Mass and the other is in Volume. If you want to go between the two you need to make some assumptions.
Amish, I believe there are people who have swapped between T3 and TD0415t on 9000s, both 2.0 and 2.3. In every instance the TD04 was considered the much betterturbo in terms of feel.
From what I have heard, and top end gains from the standard T3 or grossly offset by how shitty the spool is. I have not heard of anyong sticking with the standard T3 in those scenarios.
As others have noted, a T3/T4 would be a worthy upgrade, only problem being the lack of T3 manifold for the ng900/og9-3
Exactly, and with a "smaller" TD04 I have made 320lb.ft at the wheels, and 270whp will less boost. I know, 2.0 vs 2.3, but still, pretty clear its not an upgrade.
edit: mine was on a mustang dyno too
