Ignition Timing?

[dls93tsi]

Where should I set my ignition timing at?

I have it at about 5 btdc, but it still seems like it is pulling the timing in upper RPMs and it is not really overheating the motor, but making the exhaust manifold red freakin hot, which cant be good for the new turbo.

Should i retard it farther back, or is there another problem?

LIke I said, the motor pulls good until about 3500 then it lags and i lose power...like, a lot of power. Its a fresh motor with the rings and all seated well, my compression test is 131 all 4 cyl., I have lower comp pistons in, Im assuming thats why the numbers are lower than is in my Haynes manual.

Bad for your Turbo? What about the KNOCK on those new Venolia's?

I still say that when you SEE 5 BTDC when setting Base Timing - you are REALLY at 7.5 because of the totally screwed up angle you are looking at the scale from - Take your fingers & pretend they are the 2 marks you are aligning - Then move your fingers at that angle & see where the marks go.

And with your symptoms I would back off the timing yesterday to at least 2.5 (which would still be 5 in my book so you wouldn't REALLY be reatrded) - If things don't change for God's sake lower boost & or Timing even lower till things mellow out a little - here's a recent Timing/Knock thread...

Nice mod list - got a Pocketlogger? Pix? P-Logger reccomends at least 15 degrees advance at WOT BTW...
