I know most of what you guys are saying is true. It's just hard to think of an 18 second A body losing 1000 pounds and running 17 seconds. I always heard a 1/10 per hundred. But in slower cars like the example above I have gained more than a tenth.
I think 14's are decent. especially for a 318. You also gotta figure the money spent vs. how fast you go. If you spent a ton of money 14's aren't that fast.
What are the rules regarding stock type flywheels? In the back of the NHRA rulebook "general regulations" It sounds like you can't run a stock flywheel at all? I always use to but it has been awhile.....
