spark plugs with blower

mrvids · Jan 21, 2009

I need to know what plugs & gap I need to be running on a '97 Saleen with an aftermarket SVO blower running either 6 or 8 lbs of boost. I was told I need a nonprojected plug gapped at .030 to help stop detonation.
An Autolite 3935 was suggested.

NGK BR7EF , gap them at .035

The general consensus is a plug that is a step colder than required for a NA engine is best to eliminate detonation.

Autolite 3923's gapped to .035 is one of the plugs I've seen mentioned as well as NGK TR6 (step and a half).

I have ngk tr6 at .35

+1 on the TR6's. I'm no expert, but I don't think you have to worry about a non-projected tip at that low of boost. I know a non-projected tip will help keep everything working properly at higher boost levels.

I've used TR6's in the past in my 5.0L running 11lbs and they were good. Gapped smaller, but that gap depends on boost.

me too... thats with my old blwer (sn2000) on the 4.6, they ran fine.. Might have to close the gap a tiny bit with the new novi 2000, not run it on the dyno yet...
