#958, "Dyno success"

Is what I was able to get. 012 is what I started with, and 015 is what I ended up with after a few runs to tune the spark table. I only tweaked it by +3 or +4 degrees here and there, I concentrated on the top end and in the "spool-up" area mostly.

The runs were made with only spark being changed. I did not touch the VE table or the boost controller at all between 015 and 012. The boost pressure was about 15 PSI at peak torque, then it slowly goes down to around 13 by redline. The MS is able to hit the AFR targets very well, the AFR is about 11.5:1 at peak torque and slowly goes to 12.0:1 by redline. I am using a set 415 cc/min fuel injectors which are pretty much maxed out. My duty cycles are around 83-85%, I could probably increace the static fuel pressure which would allow me to increace the boost pressure a bit, but I don't think it's really worth it. It's probably time to put the 780's in.

The thing I like the most about these stock cams is that torque peaks right around 3500-4000 RPM's, which is about 70-80 MPH in 5th gear. Heh, I never have to downshift, just put your foot down and bam, 273 foot pounds at the wheels.

006 is an old run that I made with my Crower 3's and the 8 injector setup with similar boost pressure. Those cams suck with a turbo. Just thought I'd throw that graph in there.

Here is my spark and VE tables that I used.
