Its not about hp.
Find an eddy current dyno that will hold rpm steady, then you adjust timing and watch torque readouts change (increase or decrease). This is pretty much infinite load so its gonna be darn safe. When you see torque gains nose over or decrease, you know you have hit the limit and should dial things back.
With a good dyno that can constantly hold at a certain rpm without adjustments (some old ones will not be able to hold the same rpm when you add timing because torque will go up) you could completely tune your spark table in about 10 minutes. hard on the engine, yes. Probably easier then some people who make 150+ pulls in a night of tuning on a crappy accellerameter dyno.
Then at the track you could make decisions where to add timing based on listening devices etc. Load at the track will probably be less because you will never be stuck at a certain rpm. I don't know if we locally have any good eddy current dyno's that actually work properly Too many people just want #'s on a piece of paper.
You are at the power level where 0.1-0.5 degrees of timing can make 20+whp.

+1
you want to hit MBT (minimum best torque).
if knock occurs while torque still increases (so before MBT is reached) back off timing 2-3 degrees to be safe and move on to the next load point.
you'll likely not reach MBT at all load points so better get some headphones out to play it safe.
as odonti said, you should be able to have a complete timing map pretty fast!
Well lets get some headphones and see if that timing is warranted
I am on track for doing the same thing.
One thing about good flowing turbine setups etc, is that they require less timing for MBT (minimum best torque seems to be the proper way to refer to what I was getting at).
Maybe your turbo isnt as dead as you think it is. But people saying the holsets they are talking about are better then the 60-1, I disagree wholeheartedly. Ive seen them run 10's even at high altitude without the boost turned up all the way. I think your turbo has mid/low 10's in your weight car.
Holsets now are a whole heap of trouble IMO, I was looking up counterfeits today and they even make fakes of the crappy holsets. This has actually been happening for years and there is info on holsets website about it and detecting fakes or those who are selling fakes.
i say JT just giv'er.
ur obviously doin somthin right,
dammnn that some nice run!
Damn JT, you've got that thing singin'
Nice passes.
Thanks guys
need to research timing a little more before I play with that...

So, I centerlined the cams today... found exhaust was -6° and intake was -2° and my crank reference was 4° off too, so.... instead of 12° ignition timing... it was at 8° ...

JT,
The car is coming out of the hole and thru the gears much better than before! It is getting "up on it's toes" as the front looks like it is unloading, but much better.
