ls9 cam dyno results lq4
 
from this thread https://www.performancetrucks.net/fo...-511740/page2/

the car is a 67 firebird with 2002 lq4, 80mm bbk TB, muncie m21, 12bolt 3.91rear, stock manifolds with open dual exhaust and some advanced timing with hptuners
it feels really great driving it, like stock until you push it

and finally 22whp and almost the same on torque with this cam hope i works great when I boost it

sorry for waking up an old thread, but just to inform you with a holset ht3b and 8 psi it made 570 whp and with 11 psi 600whp , I dont have torque graph for problems with the dyno ; it was made with a ultra safe tune, 16 degree timing and like 10.5 -10.1 afr

old image, it doesnt show anymore up there
