^^^ Had a guy in my area (IndyMKIII) ask me if I wanted to drop by his Tech class and do a pull on the dyno tonight. Running 93 pump gas at between 17~18psi range we did a couple pulls. The pull in the video is showing an out-of-focus 427.14 and the image of the chart is just over 420.80hp at 368.22tq. Only change since my summer numbers at 394hp were the cam pulley adjustments I made yesterday to remove a little overlap and shift power a bit higher in rpm band. Torque was pretty much the same on the summer pull, so just shifted HP up and increased about 33hp overall. I retarded both intake and exhaust... -2* on intake and -1* on exhaust, everything else is essentially unchanged.
We did a first pull at about 1psi less and it was about 20hp lower at 408hp. That's about right. 20hp/1psi or so.
I think that's decent street numbers for a 120k mile plus original stock bottom end and a few piggy-back components from HKS. I'm running 550cc and have some headroom, and the cam pulleys are still just being diddled with, so optimum is an unknown yet. I don't want to get too greedy, either, since everything works well and I'm having fun when I drive the car and this is what it puts down to the road anytime I drive it around.:biglaugh:
BTW, since the cam adjustments, I didn't really do any tuning since yesterday, and you can see the "dip" in the curve that would likely work it's way out with some fiddling. I also have it running really rich to be safe... upper 10's to very low 11's on the two pulls.
