What timing are you running for peak torque and max RPM
What timing are you running for peak torque and max RPM?
I realize that this is dependent on mods, what octane gas you are running, boost, etc. However I thought that it would be interesting to hear people's timing numbers for peak torque and max rpm.
In addition you might want to factor in the actual timing number at peak torque (vs. the number on the map for that given load) since many of us have a little knock in that area which results in less timing advance from the map number.
It seems like you could build a good map around these crutial points.
4* - 7* at Peak torque depending on knock counts (Approx 3750 RPM)
14* or 15* at 7000+ RPM
See sig for mods 21-22 Peak Boost, 93 Octane
From what I can see via logs I am hitting 240 load max.

I'm running the White Rabbit which actually hits peak boost a little later than the stock turbo so I run a bit more timing at peak torque.
7*-8* at PK torque (4000 RPM)
20*-21* at 7500 RPM
Mods are in my sig. I run 22-23 Peak boost, tapering to 20.5-21 at 7500 RPM according to GM 3 bar MAP sensor. 93 Oct. 11.1-11.3 AFR.

21 psi via gm3bar and ecu+ taper to 17 at 7500 (reads 24-25 psi peak on my defi gauge)
2*-3* from 3500-4000 (260 load)
15* at 7500 (220 load)
93 octane
afr's between 11.5 and 11.1 3rd gear and up, depending on load and gear. Still tuning.

2006 EVO IX - 11.2~ AFR til 7000RPM 11.0-10.8 AFR til redline (7800rpm)
Started pulls at 3000rpm..
0 deg @ 3600 rpm
10 deg @ 6700 rpm
300 load @ 3600 rpm
216 load @ 7000 rpm (damn boost droppage )
15 degrees peak timing at 7250 rpm til redline
91 octane, 23.5 psi (probably less, boost gauge sucks)
0 knock across the board
