Dropped a pulley size today
Well, it'* pushing 80* outside, so I figured it'* a good day to check my summer tune. Here'* a scan with my 3.0" pulley.
My timing is low, but I set it there to be safe. I have no KR under WOT even with the higher temps.
So I dropped to a 2.9" pulley.
Looks tiny.
Compared to a stock pulley.
And here is another scan with the 2.9" pulley.
My boost went up by almost one pound. My timing went up a little as well. AFR is a little lean and still no KR under WOT. I had one small blip of KR at the shift point, nothing to worry about. When I get a chance I'll have to bump up the timing a bit. Right now I'm at 13*-17* and would like to get it at 15*-18* or even a little higher.

Subtract atmospheric pressure from that, My peak with the 2.9" was 27.42 at my elevation it'* 14.4 so that'* 13.02 pounds of boost. About as high as you want to get. I could push it to 14 psi, but I'm already running hot. I watched my IC coolant go out about 20* after getting on it a few times.
