ok guys
I am looking of ways to prevent knock before it happens
not sure if there is a way to stop shift knock too but if we can get that done too
now before any smart ass says race gas, xylene, toulene, alky etc
I am looking to get this done on pump first
I have alky in the mail
you can check my sig for mods but one I was wondering about was the dutteweiler neck everyone says that you can run like 1 1/2-2 more psi
anyway it seems no matter what I do I keep getting knock
I am really not running that much boost at all, like in between 16-18psi
it knocked at 5.9 with O2s at 812
problem is that I cant seem to drop the fuel PSI anymore
I think its at about 40 line off now
I only made one run last night when my speedo said 55ish or so (I have the gear reducer for the 145 speedo)
it knocked at 47MPH could this be a shift point? it did go away when I let off around 85 or so but the most it stayed at was the 5.9 at the 47 MPH, it didnt go higher
so what are ways to prevent false knock or knock in general?
is it anything with the EGR? how about spark plugs is it safe for me to use the other level which is the ac delco AC42s?
a chip with more retard or advance?
please help
thanks
Carl
