I'm hoping to hit the dyno in January. I'll post logs and charts, regardless of the outcome.
Question for the masses:
At what point would you know you have exceeded the intercooler's capabilities? I'm on the CTS FMIC currently, and apparently ED can't log IAT's properly. 4th gear pulls end up with IAT's hitting their starting value at about 6.1k rpm, ie. starts at 8, drops to 7.2, goes back up to 8 by 6.1k

Sounds normal to me? Generally you just want IATs to stay below the point where the ECU starts pulling timing. That seems to be in the 110-120F range unless Mabo has changed this parameter (unlikely).
Thanks, Diggs. The IAT increase over the course of the pull looks normal to me. I'm doing logs in 40-45 ambient weather, so very unlikely that I will hit 100-120*F IAT.
Just a gut check.

So new update in regards to the GPOP IS38 balance/rebuild that went pop.
"Ilya Aronov UPDATE:
Just got off the phone with my local boost shop and they have found some incorrect things with the NEWLY rebuilt turbo along with the parts used from overseas. They are going to fix what they found and check the balance. I have asked them to put this all in writing so stay tuned for the exact results.
I will be filing a chargeback to GPOP for all the incorrect work that they performed."
Yup - saw that.
I'm still going strong. Had a 29psi overboost this weekend while logging on the shift from 3rd->4th ; no problems
Find a shop you trust and get all of your work done there!
The IS38 is already a hit or miss. To add the rebuild/rebalanced to also be another hit or miss is terrifying for me if I got it balanced by them.
I stand by just don't balance it. Either build it hybrid or leave it if it was good with no real shaft play.
Not a hit or miss with cermaic dbb conversion done or even Littco modified work..
