I have a Saleen Supercharger with the stock 4-5lb pulley on my Gt. I have the Brisk 3VR17YS spark plugs in and gapped at .032, and when the car is cold I have a hesitation on takeoff. I talked to Br**nspeed, and they said to just put in the stock plugs, and leave the gap as-is (.042). Should I pull these Brisk Plugs and put in the stock plugs?, and if I do should I gap them down to .032?
Thanks
Rocket - your not producing enough boost to have spark blow out, which would be the only reason to gap down to begin with. I would do as Brenspeed mentioned and see how she runs, if there is hesitation then begin gapping down.
