If you have the NGK one step colder (BKR7E or BKR7EIX) spark plugs installed on your SS/SC, what do you have them gapped at?

 

.045

 

.037

 

thinking about spraying?

 

My NGK BKR8EIX Iridiums are gapped at 0.028. Works well for me.

 

.035

 

what the benefit of a smaller/larger gap?

I know I have read it before, I just forgot

 

A smaller gap gives you a harder, but not neccessarily bigger spark. If they're too close for the environment they're in, they won't do enough work to excite the other molecules. A bigger one gives you a larger, but not harder spark. Too big and the flame will simply blow out. This is why it's a precise thing.

 

.045 with stage 2, 2.85 pulley, intake, gmpp exhaust manifold and cat back and car runs very strong.

 

.045 with GM Stage 2... According to Intense's website they start to gap the spark plugs smaller wuth the smaller pullies

 

We've done a lot of LSJ dyno tuning and testing, and here are our recommendations:

Stage 1 - 3.30" to 3.20" supercharger pulley - .045" gap
Stage 2 - 3.10" to 3.00" supercharger pulley - .045" gap
Stage 3 - 2.90" to 2.80" supercharger pulley - .040" gap
Stage 4 - 2.70" to 2.60" supercharger pulley - .035" gap
Stage 5 - 2.50" supercharger pulley - .035" gap

A few notes:

If you plan to run nitrous oxide injection, go right to the .035" gap, regardless of your pulley size.

Also, we've proven on the dyno that the $1.99 spark plugs are every bit as good as the $12 ones. There's just no need to waste your money.

i have my plugs torqued to 25 ft/lbs is this what everyone else has theres at?

 

i have mine at .036 but considering trying .045

 

Thanx again BAD GTP,

 

so with my mods that i have, im also plannin to use hp tuners to tweak a lil bit, is it still ok to run a .045 gap?

 

what if you considering bumping the Rev limiter to about 7500-7750 and a 2.8 pulley
