hope someone can help i'm trying to turn the boost up on my cally turbo but the spark keeps on getting blown out i've got ngk's in and there down to 0.6mm,i was thinking of putting bosch super 4's in so hopefully the spark won't be blown out does anyone know if these plugs are good or crap,or are there better ones out there.
right mate i am no expert but you do need a boost gauge to see what you r running it might be the boost limiter that you r hitting and not the spark beeing blown out so get a gauge asap and let us know what u r running ,ty getting one of a mate just to test it
but in the long run get one your self
for proper troubleshooting you need both a boost gauge and an AFR gauge.
If the mixture is OK under boost --- THEN you might start looking for spark weaknesses.
First check that the plugs are OK, gaps are 0.6 - 0.7mm, heat range correct, leads and distributor cap fine, rotor too.
