no alky injection
I have a coolingmist alky injection installed but I had to send out my controller because it broke
this is with 94 octane sunoco pump
**one thing to mention is the boost tapered down to around 12psi after around 7000rpm or so. this is getting out of the efficiency of the .84 A/R and a 1.00 A/R would have probably picked up 20 or so whp at the top end , but I wanted a little more 'area under the curve' so I went with the slightly smaller A/R

Awsome #'s for 15lbs! I thought about a bigger turbo with a smaller A/R btu everyone thought those numbers couldn't be done. Nice to see they can 
I was going to ask if you were on stock ports then I read your sig. So it looks like the limit of the small A/R is 7k rpm. That actually looks very nice for a street car.

Great
I couldnt stop grinning the whole way home just building boost and feeling the rear tires slip a little... didnt beat on it too hard, but def made the full boost and it really kicked me back in my seat. I love the sound of the open wastegate, it still scares me hearing it open up and its almost a knee-jerk reaction to let off the gas at that point because its so damn loud
It has been over a year since Ive been able to drive the car hard, it was down for almost a year getting turbos and new motor and then of course the break-in.
