newbie to boost 80mm turbo
As far as your #, there are a lot of variables. Are you just chasing a #? With 10.4 cr, I would defiantly spray some meth with the boost, back the timing way back, and if it were mine, I would keep the boost under ~12 or so. JMHO.
01 z06 SBE LS6 (ls1) ~ 10.9-1 compression PRC heads that flowed well/90mm fast
229/229 .615/.615 114+3 made around 550 tire on 94 octane/ 7lbs with low timing around 12 degrees if I remember correctly.
Still on pump gas it was 7lbs/ around 20 degrees he went 10.3X banging gears. That timing on 94 Octane eventually hurt the motor mind you.
Same car forged 383 (ls1 based) made 950 to the tire. Lower compression of course. No idea what fuel or timing. But if I was in your situation I would grab a set of heads that brought me down around the 9.5-1 mark and go to town.
