i have a stock sleeve lsvtec, eagle rods, nippon cast pistons, b16 head, gsr cams, victor x, blox log manifold. holset turbo at 15 psi creeping to 15.9

my total timing is around 17.25-18.50 on high cam full boost. is this too high for it to last on 93 pump?

i tried it on 17 psi on sunoco 100 unleaded but turned it down for fear of blowing it up without water meth running yet

 

look at the spark plugs? is there detonation?

i run my timing a little less than that at 16 psi, around 14-15 but every setup is different.

 

Impossible to answer correctly. Your suppose to stick the car on a dyno and ask it how much ignition timing it likes. Not tell it.... Every setup is different...

 

Doesnt sound off. Do some plug reading.

I was expecting some 25-30psi numbers lol.
