Just how much timeing can you add with WI?
Ive went from around 11 at full boost to almost 21 degrees with no knock... but it doesent really seem to be much faster.. of course this is right before I discovered my messed up turbo bearing but is this normal?

i run 29 or so btdc at 18 psi. Did you adjust your AFR's, are your spark plugs good? WI systems like to run alot leaner than the **** you guys tune on fmic's aim for low to mid 12-1 and you will be better. Is there a turbo leak or is the bearing damage so bad you cant reach full impeller velocity? Thus increasing backpressure and the cfm influx in one fell swoop.

thanks guys, I was a little afraid to experiment with that much timing, but now I will! I already have it around 12.2 to 1 in boost, so im good there. Still not sure what caused my bearing to fail, but I had a boost leak too... the car is getting a total makeover this week so by next week I should be back on the road with a 3 inch exhaust, rebuilt turbo, depower rack, and proper WI tuning. Cant wait!

umm i get on the raod and hit it as hard as it will go and then observe how it does if no knock is pressent and it still pulls strong i edge the timming up and do another pull. If knock becomes present etc or i dont make anymore power then i will back of a hair. It is not that frigging hard man you just need someone to drive your car who has the ***** to push the **** down and some raods like mine where you will be left fairly alone.

Well heres how I figure it. You cant get the timing map dialed in without a dyno, and that is really true for your timing at cruise. But under power atleast you can usually feel differences.
I also think we are lucky because when advancing timing at the top end, a turbo car will run into knock before you can advance timing too much and loose power. So I feel just advancing your timing until you get knock then backing out a little will give you most power. This is unlike N/A engines, where too much timing is bad.
So when I get some tuning done, ill post my map up!
