It went great... Just now getting to know the knock monitor display and trying to figure out the relationship between knock, rpm, a/f ratio and timing. By tweaking these individual item, there seems to be alot more hp available (more power under the curve, but not more peak power).

 

Actually, the knock display is working great. I just hooked it into the rear knock sensor input to the ECU. The rear one is closest to cylinders 4,5,and 6, which seem to be hottest. (and probably more knock prone) You can definitely tell knock, but at high rpm, its a little tricky, cause there is some noise that is not actually knock. The key is to know what is going on by running low boost and learn the noise signature to separate out what is really knock, and what is just normal noise from the engine. At 6000+rpm, there seems to be a sensitivity to knock, and I'm not sure yet if there is *really* knock going on at that rpm. Surprisingly, for me there is very little knock below 5000rpm, even at around 11psi on 94 octane. That could be because of the cam reducing cylinder pressures below 5000rpm, though, so don't take this as meaning that anyone can just dial up 11psi on stock comression without issue. I think my new torque peak is around 5000rpm now. The bigger cam seems to allow more boost at lower rpm. The end result is the same, though, cause torque output from the bigger cam at low rpm is reduced. I do like what I am finding, though. It seems like the car has alot more oomph around 3000-4000rpm, which the cam took away. The down side is that before on the stock cam, I could run *more* boost up high (5500+rpm) because the engine didn't breathe as well up there and you could just up the pressure. Now with the cam, it breathes better up there and the cylinder pressures are higher giving less margin for boost (not what I was hoping for). We'll see what happens.

 

have you considered alchohol injection? it seems like it would allow higher pressures on the same compression. and in your case maybe allow you the pressures you desire with the new cams.
