Yup, that is the same turbo i have and tested. This is what we will be offering if the GTX doesn't play out well.

I had some issues with my ECPro software last night so i didn't get to dynoing, but we will finish this all up tonight and post results tomorrow!

Lots and lots of good data!! So here is a quick shot of the turbo response. Basically there is zero response change on the Dyno. More info tomorrow!

Without being here for a few more hours, that is all the time I have tonight. Let's just say the response issue is off the table! Power data is good for sure I think it will come down to is the extra $ worth it..... I think yes as people pay more to get the se results we saw!

Jeff, do you know about what mass flow rate each torque/power curve corresponds to? I was just looking at the compressor maps and it looks like at the pressure ratio of 3.0 (about 1.9 bar boost), the GTX won't start to show gains until about 45lbs/min with those gains getting big at 55 lbs/min. And of course, the regular GT dies around there whereas the GTX will push to ~65lbs/min.

Did you have to change any of the tune? Any timing adjustments or anything like that?

One last question, any plans to do the GTX3071? I imagine it will make similar power as the GT3076, but the on/off transient boost response should be better. Of course, only way to check that is on the street.

I'm guessing no post means less than stellar results.

#1, reading comprehension: "Let's just say the response issue is off the table! Power data is good for sure I think it will come down to is the extra $ worth it..... I think yes as people pay more to get the se results we saw!" That implies to me that it did well.

#2, Perrin is in Oregon. It's 9:35am. They probably are barely in the shop.

Must be your tune.

I never doctor, just make the lines clearer to see! I can post up the real ones(which i did with my iPhone) but they are hard to see when scaled down to fit on out site and NASIOC.

Here is something for you guys in the mean time.
