Rules for nhra super street

[Cisco Kid]

my car is right on 2800lbs,but my chassis is certified also...my car is capable of running 150+ but i short shift so there is less wear and tear on my junk...plus the chassis cert is good to have just incase there are any structural damage that is un seen...and i had to do the physical and all that good stuff...but i have been weighed,but never checked my wheelbase good luck!!

I've seen plenty of light cars in S/ST. I remember an old Brogie roadster in CA that ran it, he had a huge rear bumper that was rumored to be mostly filled with lead. Looks like 500 lbs is max ballast:

If additional ballast is needed and is permitted by Class
Requirements, it must be permanently attached to frame, bolted with
two 1/2-inch-diameter bolts per 100 pounds, with nuts welded to
bolts. Maximum amount of removable and/or permanent ballast,
unless otherwise stated under Class Requirements, is 500 pounds.
Cars running 8.49 and quicker are limited to 250 pounds maximum,
per SFI chassis specification.

Per Gen Regs 4.2.

I agree that you woudl be called on the weight long before the wheelbase. Also as stated anything over135 and you need a license. I have been weighed, but only after final rounds, however I imagine if someone said something to the officials that you could be weighed at any point. I am well over weight and go over 150, at anything over 150 you will also need a chute. When looking at licensing you have to take into consideration the MPH as well as the ET.

I think the 2800 deal is crazy.. people are still running crazy mph.. They need to rethink the weight deal cause there are alot of people with older cars that cant run 632's and go 175mph in super gas, but would be cool going 10.90 at 135...

I wish they would put a mph cap on atleast s/st..

Wasn't the original intention behind the 2,800lb. rule to shy away some of the cars capable of what was considered big MPH for the time from running s/st? If you lowered the weight but want a cap on mph, wouldn't those two work against each other? At that point you would potentially be inviting more cars capable of 150+mph into the class so what would be the mph cap? I also think that a majority of guys capable of 10.90@135 are already doing it.

I believe a some of the racers felt that 2500 lb cars were hurting the class, and did not like the idea of a S/G car running SST. They had cars that were just over 2500 lbs. And one year they had stutter boxes, before the throttle control, cubic inch scenario started to take off. They also changed the tree from .4 to .5 seconds. I believe this was 1994 when the rules changed. Hurt some racers that had been running that class for a years. They did not high mph back then like today. High mph for a SST car in 1987 would be 130. And I don't believe that any one was going 130. Lot of races throttle controlled it on the big end.

I was going 10.90@145 in 1997 in a 3200 lb backhalf, its all relative to what your used to.
