If you can do that then most Greek dyno operators are as you say crap!

Most dyno operators and dynos are crap, not just greek.
I've learned this much when working on various dynos.

From the look of the graph this must have been a 0.82ar

yes it has and only street tuning running a bit to the rich side. but ran well

The new Garrett turbos are definitely interesting. Obviously a 660 won't make 660 bhp, more like 550 at best. I can say I really like the efr 7163 on my stroker with quick spool valve. It dives so nice in high gears. Almost like a diesel. But it keeps pulling after 6k rpm.

g25-660 Red vs EFR7163 Blue



I'm tempted to say that the g Series will be more reliable when overspun, where as EFR's have proven to disintegrate when overspun.
I can only imagine what the new g28-770 will bring to the table.

Hmm, when I read the discussion here, it looks like my budget ~500hp turbo solution isn't so bad after all. Seems to be even a tad better than a 3076...

Thuppu, what about a GTX 3576 then?

Have no experience with that so can't say a anything, but seems to be quite a lot bigger turbo for higher power levels. Doupt it will spool the same as the smaller competitor..? Could be a fun turbo anyway.
