Anyone with experience using BW S475 T4?

I have a T4 S475 1.25 a/r that's going on a 370" LQ4 in a 3100lb Mustang. What can I expect from this turbo as far as spool time, power or ET, when will it become a restriction for me? There's a lot of threads with the S475 with T6 but I went with the T4 for packaging purposes.

Thanks

I am running one on my LQ9 in my Silverado SS and it has been working great. Spool is good, it is a little lazy at part throttle but that is what i wanted since I tow with it as well. The truck has gone 11.7 so far on a bone stock motor in a full weight awd truck.

I had one on a 6.0 LQ4 and it spooled fast, went 115/145 16# a little under 3300#. The wheel sizes(83mm turbined one) are almost identical to T4 GT4202 and PT76 (76gts and 7675)

Thanks for the responses all - i've decided to send it back to FI and have it upgraded to the 80/87 version, possibly with a race cover as well.

Here's a pic or two of the turbo
