Initial thoughts on Pete's Intake/Exhaust cam combo

[XfireZ51]

Here's the compare between Intake/Exhaust cam combination vs. Intake only cams. Each has ported top end and heads.
Top line is current config but prior to tuning.





Here's where I started and ended the tuning session. This was all fuel. Timing really made little to no difference from previous.

Got it, sorry, duh. Nice nice numbers. Someday when I grow up.

Now back to your thread....

Todd,

BTW, increasing the Injector Offset for the Accels did what was intended. I was actually able to reduce the DC% and VE% for WOT in the table by about 10%. Certainly gives me more headroom w same injectors. I used the voltage table but then realized I could target the additional PW by using the Offset v PW table.

It's 533 or 545 depending on your parasitic loss factor.
