cp tech ping with 100oct help please
i have a pinging/tinging sound coming from the motor only under hard accleration seems to be more noticable in 3rd and 4th gear. i am running 100 octane and have a cp tech 11.5, hot cam 2, 5mm stroker, full yoshi system, k an n filter intake and no lid so i dont really think it is a octane problem so what else could it be, i only hear it under hard accleration ive tried lugging it on hills to try to put a big load on but nothing, could it be running hot, havent had a light on or anything but did loose my coolant overflow cap awhile back and now it is just covered not sealed. help please this is kind of got me worried?
