Flyboy,
Mr. Guthrie speaks with authority when it comes to nitrous on a stock motor (no rods) in 1 mile.
JoeA can tell you what the salt likes and doesn't like. A ZX14 with a small amount of juice on the rich side can make you go a lot faster, but the tragedies of nitrous are still there.
Wayne Pollack told me once, the secret to going fast on a long distance, is to go fast fat and lethargic. I have built my speeds up using that same advice. This year I plan to use even more nitrous, but in 2 stages and yes, I also expect to see my motor in a basket after the next meet. But I will return and I will go faster than the time before. I keep learning what not to do, sooner or later I should run out of things not to do. Then and only then will I hit my goal.
