national record set but too fast
 

I've seen a racer claim to have set a national record, but disallowed for being too fast.

What am I missing?

Perhaps the entire field was too fast?

That would make the second pass the new record, but the first pass was not close enough (within 1%) of the second (faster of the two) for a back up.

x2 that happen to me but still got the record.

Thanks.
Interesting Rule!

So it takes at least two passes within 1% of each other to beat a record. Is this standard across classes?

The guy said most of the other racers were much faster also, so maybe a big shift in conditions/DA from when their first passes were made.
Maybe other racers ran faster than the old record also?

Happened to me once too. Was relieved I didn't get it. Didn't try to back it up. We ran off the records back then. :-)

Re: national record set but too fast
 

Applied only to Stock and S/S...just because a racer is faster than the record does not means he automatically sets the record. If a racer wants to attempt setting a record he puts a big R on the window and pulls into the record lanes. He then must make two runs within 1% of each other, one of which must beat the existing record. If both runs are quicker than the existing record but are farther than 1% apart, the faster run will back up the slower run and that slower run becomes the record.

Re: national record set but too fast
 

That sounds very sensible.
I know that land speed records take an average of two runs always.

Do many or most of stock and SS record attempts fail because of the 1% rule??

Any cost to try?

I guess we cannot see a history of these NHRA record attempts?

Re: national record set but too fast
 

The cost? A tear down. And enough white marker to make an R on front and rear window, with a circle around it.

Due to the schedule last year in Las Vegas, we actually tore down before we even ran once. There just wouldn't have been enough time to do it during the runs. So we did the teardown first, and the engine was sealed.

Then we went out and got the record with two runs.

Another driver behind us in line decided that he could could run for the record too, so he put the R on his car, and tried. He spun and missed on his first run, so it wasn't an issue, but I was wondering when he thought that he would tear down.

We haven't run a lot this year, maybe eight or so races, but my engine is still sealed up.

David, you do know that the sealing of an engine is only good for that event. If you were to go out and set a record today, you would still have to tear down.

The way it works is this.
If you set a record the backup has to be within 1% or "faster". If you go slower on the backup but it still is faster than the record. That becomes the record.
Here's some examples.
Existing record 9.00 First run 8.49 record set, backup is 8.94. New record is 8.94.
Existing record 13.35 First run 12.81, backup is 13.25. New record is 13.25
The faster run only counts when the runs are within 1% of each other.
The backup is not always the second run, or even the slower run.
You can take this to the bank. On this I know. I've set enough records

One thing I didn't post was that the first run has to be under the existing record. It can't count as a backup if it was over the record.
