Thread: Spark plug gap

That more or less reconciles with what I've read elsewhere too - I'm going to start 0.055".

Thanks

Yes I've scanned, real time, for KR.

I MAX out at 4* after extended WOT (around 70 MPH). during normal driving, I can't get any.

I can also check for manifold pressure, I've just had no reason to thus far.

I'm at 5400ft altitute. Less air density and, more significantly, less O2 density.

The car has 138k miles on it. I dropped pulleys with 112k miles. That's 26k miles and about 2 years (I would have to check) with this setup. It's not going to blow up. The ONLY other mods I have are a K&N filter (stock ai - about 13 years old as I changed filters when I bought the car), MSD wires/coils, 3.2 pulley and gatorback. Now flow mods whatsoever.

If I drive it at sea level and run WOT, I would EXPECT problems and a grenade under my hood.

It's reality - not good or bad.

This car is my daily driver. I don't care to have it all modded out. The only reason I dropped pulley sizes is that I replaced the coupling a while back when it sounded like I had rocks in my snout. I decided to also throw a smaller pulley on it as well.
