I HAD A T3/T04B .82 TURBINE/.60 COMPRESSOR WITH A 50 TRIM RUNNING AT 9 PSI ON A D16Y8. A LOT OF LAG DUE TO THE BIG EXHAUST HOUSING. IT STARTS BOOSTING AROUNG 4,500 RPM AND FULL BOOST AROUND 6,000 RPM. VERY LATE BUT STILL PULLS HARD. I WAS JUST GOING TO REPLACE THE TURBINE HOUSING TO A .48 A/R BUT I SOLD IT INSTEAD AND GOT A T3/TO4E .48 TURBINE/.60 COMPRESSOR/50 TRIM. ANY ONE WITH THE SAME SET UP? WHEN DOES BOOST START AND FULL BOOST, MY CASE 9 PSI? JUST WANTED TO KNOW BEFORE I PUT IT NEXT WEEK. I CAN'T SLEEP AT NIGHT. NEED YOUR INFO. ANYONE'S OPINION WILL BE APPRECIATED. THANKS A LOT. I'M TAKING NYQUIL IF I DON'T GET A REPLY.

 

I'm runing a T3T4OE .57 trim .63 A/R on mine........starts to spool about 2,800rpm and full boost (.65 bar) by about 4,500rpm
