·All I can say is WOW, this turbo is mean, especially for how small it looks. I had tried one a long time ago (sp67 .7 p trim) and thought it was a POS, but it must have been b/c the turbo wasn't broken in at all. I only had it in my car for 50 miles or not even.
I just tuned my a/f to 11.8:1 (which is what I normally run around town, unless I plan on doing some long pulls, then I tune to 11.5 or richer), which is what I had my a/f tuned to with my previous T61 .58... and the sp67 .7 p trim required about 15% more fuel at 16 psi! More than that at higher boost levels I'm sure, but I didn't expect there to be such a big difference at low pressures. Obviously it's flowing a lot more air and you can definitely feel it. The car is so fast at only 16 psi it's unbelievable; I'm spinning/wheel hopping badly until the middle of 3rd. It's so fast that it keeps making me paranoid that the a/f might be going lean or that the timing is too high. But everything looks good! I dynoed ~487rwhp at only 16-16.5psi with my T61. This feels like it's gotta be at least 525rwhp or so!
This is definitely a turbo I would recommend... one of the best I've used yet, and it would be great for someone that street races for money (me) b/c it looks so small. =)
