321.24 whp / 305.02 wtq @ 19.5psi
Well, I got a little bit of some disappointing news today. I finally got the car to a Dyno and I was hoping for some better numbers but here they are:
321.24 max power / 305.02 max torque at 19.5psi. My A/F ratio can still be tweaked a bit. I was sitting around 10.6:1 at full boost. The Dyno was having issues picking up the Fab9 COPs spark signal so the RPMs are alittle inaccurate. The bottom graph shows the power compared to MPH vs RPM for reference. The pulls were in 4th gear with a 7800RPM redline.

I didn't know what gear was best for our cars. So I should be doing pulls in 5th?
It was a $40 for 3 pulls type of night, no tuning on the dyno. Not that it really matters because the car needs to get running on a different ECU....

Thinking about just trying to go with the LS truck coil setup, not sure yet. The guy running the Dyno is a member here who had the Fab9 COPs on his Miata and experienced the same issue on several different dynos

A 5th gear pull would have showed a little more power. Leaning it out some would have made more power. I don't know anything about your setup, but with the way TQ falls off up top I have to wonder if more timing up top would have made more power. Overall numbers look good to me and there was definitely more left in it.

We're not arguing. I'm saying it doesn't really matter because the difference it would show would be same as the difference shown between two identical pulls.
I'm saying he's got other problems to fix, and dynoing in wrong gear is the least of them.
