Well the dyno WB is off.

My Afrs are 11.4 going to 11.8 out the top on my gas WB. I have made pulls in the 13s and not hurt anything but I do not make any more power going leaner than 11.5's.

On timing.

The car started with E85 which really only tunes like 105oct so in the 4k and under 30psi spike she could not take much timing.

When going to the E98 I added a few deg in down there and the car felt much better and I just focused on my 5k+ drag tuning since that is what makes the car go down the track fast and she feels way good under 5k anyway.

I find that trying to make huge TQ # is very hard on the motors and not worth it. So on the E98 I have not really even tryed and see what she can take till I get some knock. Once I get the 10:1 pistons and rods in her in the next few weeks I will push it to see what it will do in every RPM range.

In the dyno the car was sitting a 31 psi from 4-5k and than it tapered to 22psi buy redline so that huge spike makes the timing low and than boost dropping off the timing starts to come back in quite hard.
