My current set up is a 1991 gvr4 with a bastard 20g internally gated, fic 950s, 1g vrsf intercooler kit, fp2 cams and a walbro 255. Running 20 psi on 93 octane, with afrs about 10.5 to 11 by redline.
Im having a problem with spark blow out. I bought some brand new 6's and gapped them at .025. It helped but still blows out at full throttle, it won't at part throttle though. So i regapped them down to .020 and I still have blow out.
Should I now try switching to some 7's or is that just a bandaid to a weak ignition problem?
