Newby with Questions

Just got off the phone with someone who just failed chassis tag, trusted the guy who sold it to him that it would cert and had a bunch of work done, had to tell the guy that he would be better off getting another chassis as would have to replace 65% of the tubing according to the SFI cert paper

Ding-ding-ding. Been there done that! Sucks

Well that really sucks. I will check about getting it certified, make it worth more. Does it still need to be certified to run 9 1/2 seconds and slower? That's all I'm planning on doing with it.  Thanks guys.

9.999 is the magic number or at least it use to be

The rule is that all cars must meet spec, If the ET is quicker then 10 sec. then it must be certified and stickered otherwise you could race a 10.50 et with a chassis made out of 3/4 EMT conduit and brazed together

We're giving Worst case scenario  but you do need to jump threw the hoops. It's the world we live in.

Thanks for the info. The tubing is .058, that the measurement that I came up with.

If you are going to try to determine its possible spec. at least buy a SFI book. http://sfifoundation.com/drag-racing-chassis/

DON'T guess or hope it will meet spec. You could be as I found our chassis to be. I hope not but it happens all the time. George

Thanks. I'll get the book.

Got chassis certified to 7.50, no problems.  Motor ,tranny and coupler hooked up. Shifter mounted.  New slicks. Hopefully it will be ready in a month.

IHRA is 9.0 or 150mph before a cert I think.

Chassis certs begin at 9.99, and is generally accepted practice between all sanctioning bodies to use SFI specs. All chassis must meet these specs no matter what the ET, just that when you drop below 10.00 it has to be inspected and tagged
