I've re-labeled the graphs, and hopefully they make a little more sense now. It'll probably be a little while before everything gets sorted out and re-tuned.
But i have no doubt that this kit is going to turn some heads for the people who want to make some serious power, have room to grow into other/future t3 turbos, and still have a usable powerband on the street.
These graphs show the Potential that is there for even a relatively mild build. And with a little more time and some of Adam's wrenching, i think we'll be there!

did I saw right ; with 3076 .78 you got 1bar at 3 th gear about 3300rpm ? and
stock turbo about 2900rpm ?
we measure here in Finland at 4 th gear, so that would be 1 bar about 3100rpm.. ?
maybe.. ? that sounds pretty good

Yeah, i'm really not responding to the brain donors that can't atleast read the first post in a thread. The TUNE is not the problem. The only thing the tune needs is to be cleaned up once the actual problems are fixed.
Considering an evo red, which is a "larger" turbo than a non-hta 3076, seems to make about 450 on a stock block with all the trimmings and a motec/ems, I'd be happy if we end up around 400whp on a low dyno like this given the cams, ecu, intake/tb, ic and exhaust on the car now. There's definitely some hp tradeoffs on the table in each of those areas, and will probably be right around 450ish after some changes are made there - but that's down the road a little bit. First, is getting it to make boost reliably and go from there...
Jarrko: I don't have the evo8 boost curve handy, but IIRC it hit 20psi right about 3k, and this kit hits it right about 3300, not too shabby! I also double checked, and this was 4th gear (on a 6speed), not third like I thought.

IIRC, Drifto's similar setup with 3076 TS T3 .78 A/R gave abut 425whp on 93 oct and 26 psi, with a leaky BOV. The motor drove like a V8 with all that fast-spooling torque. He switched to 1.06 and it churned out around 460whp at 28 psi. These are all Dynojet type figures.

Yeah, Drifto's setup is definitely a beast and something to aim for. I think he was on a 2.3 or 2.4 as well, which must drive awesome. I'm looking to see what can be done on the stock 2.0 with the smaller hotside at first, and then make my decisions which way to go displacement and turbo-wise once rebuild time comes around.
Also, I'll see about dyno'ing in 3rd and 4th next time out, but won't have a comparison graph for an evo8 3rd gear pull on the same dyno. I would expect the relative difference from the stock turbo should hold pretty constant though. It's not like it's going to be a dog in third gear and very close to a stock turbo in 4th.
And fwiw, i no longer even need to downshift from 6th to pass on the highway as i'm pretty much cruising on boost at 2800rpm, so nice to have that feeling back!
