timing help

[whtcobra1998]

needing some trying to figure out a problem, car breaking up at 5k up. 03 headed teksid 11-1 c.r. with a vortech v1 set for 12 psi on a 98 ecu aol3, 93 oct. I was wondering if anybody with c heads have a pic of their timing maps (base,borderline) that have already been scaled. just need to see a centri supercharged c head ign maps just to see if I am missing something, thanks

What plug gap are you running? If it's having spark blow out I would check the mechanicals first.

tr6 .32 gap breaking up way to early @7 psi, but was also rescaling my timing

You're running 11:1 with 7psi on pump 93.. You could be detonating.. Have you checked the plugs etc for detonation? There isn't much wiggle room with that kind of compression etc. How much timing are you demanding?

Also TR6's aren't cold enough for that compression.. Get some BR7EF's gap them at .028 and see if it helps..
