When did the NHRA chassis certification rule come into effect for cars going faster than 10 seconds? Early 90s?
How fast could you go without one back then?

I don't understand what you meant.

If you have a car that is slower than 11.5 but has a 10 pt cage it needs a chassis cert?

I'm thinking mid or late 1970s

Call them and get the straight scoop, if anyone who works there now remembers that far back

As far as how fast could you go, it was as fast as you could go

There where many top Fuel cars in the old days, some where built good, some where not

Lots of junk made passes at many drag strips in the old days, some still do

I THINK it was somewhere around the mid-70s? Prior to that there was a string of F/C crashes in the late 60s that they found were the cause of high-speed & unsafe front tires. Tyhen you had the incident where Garlits car got cut in half (1969?), then ther was the T&T crash that killed Don Carlton ('74/'75?) I think by then NHRA figured they better do something & came up with more extensive rules for a variety of things, not just chassises

Yes, suppose you had a car that went 9s when did the NHRA require a cert for the chassis/cage. I thought it was in the early 90s? I am wondering about sportsman not the pro catagories.

I believe the Chassis certification rule was put in place for the 91 season, our cage was not certified in 90, had to have a couple bars in my SS Cuda replaced in order for it to certify for the 91 season.

My understanding is that the car E.T dictates requirements.
If you have a ten point cage in a 12 second car , it does not need to be certified.
As to when this came into play , I am not sure.
I know the requirements for tube ( M.S. ) thickness has bounced around since the rule inception too.

Just looked it up in the current Nhra rule book and it only said that it is required if you run 9.99 or faster. My chassis cert expired this past spring, but since I am only running 10.20s it is not an issue. Heck Ihra requirement is for 9.00 or quicker, gotta love it.

Thanks. That is what I was looking for. So how fast could you go before 1991 without a cert or license? 8.50s?
