Well I finally got the new turbo on after a lot of work, and hazzle with many things that didn't want to go right. Well all I got to say is that I need some 660s or bigger injectors real bad. Turbo spools preaty fast actually, it's really not that much laggier then my T28 was. It's reaches full boost (18psi) at about 3800 to 4000rpm. And preaty much instantly at a downshift. It reacts very quickly. Power came on preaty strong at 4000rpm, fairly torquey too, and would really pull hard at 5000rpm on.
Car felt like it pulled like a bat out of hell untill fuel cut ruined the fun. I know the butt dyno can lie, but this change felt preaty huge. Lowest boost I could run was 17psi in fist gear, and 18psi on second. I might be able to get it down to 15 to 16psi by playing with the actuator.
My 550s went from -26 from 5 to 7k on the AFC, to 0 across the power band to only get a lean .91v to .92v of max richness. My car likes .94v ideally, it's plenty safe, and makes lots of power there. Car was so crazy lean I never got going very fast, but obviously theres a huge difference in airflow going on. I was also getting 15 degrees of timing on first and 14 degress on second. I defenetly need bigger injectors bad.
On the logger the airflow number went from 23 to 24lbs of airflow on the T28/28 at 19psi, to 35lbs on the 50trim at 18psi. This turbo flows like mad. The HZ on the AFC went from 1840s @ 19 psi on the T28, to 2200 on the AFC at 17psi on first gear. Second would cause three huge fuel cut burst and prevent me from getting a good readings. I can't imagine what this thing will flow at 25 to 28psi.
I'm disapointed that I don't have bigger injectors to fully test it out. I also can't wait to see what it does at 20psi on pump. And maybe a little race gas if it's not fast enough.
Here are some misc pics of the install:
The pic with all the turbos, are a T25, FP T28/28, 18G, and the new PTE 50 trim.
