What is the speed or time at most tracks for mandatory safety equipment like roll bar, shaft loop, steel bellhousing, 5 point harness and the like? thanx
Most tracks are ET based for the equipment your talking about, based on the sanctioning body rules.. The only mph based rule I am aware of is the parachute one, that is 135mph or faster.. But I have been away from the track for a decade or two, so things may have changed, rules may have been added. It's always best to check with the track your going to run at, they typically have the safety rules on their website. JW
+1 on Jim "When in Rome..." My little brother techs at KID in Wichita, it follows NHRA rules. http://www.nhraracer.com/content/general.asp?articleid=47000&zoneid=132 If you have specific questions, you can PM me.
Nothing specific, just an average like under 11 sec. is roll cage, or what ever. Thought some of U guys that go to the tracks a lot could shine some light on it. just wondering don't think i'll be 135 but ,,,,,,
I don't race a lot but if I understand correctly, if you make a sub 11 second pass (at Atco in NJ) without a roll bar you get sent home.
Thats what i thought, it all comes in at about 11 sec. thats what it was 25-30 years ago. you would think that it would be lower now that there are better brakes, tires, seatbelts, and helmets.
Having read a bit about the Dodge Hellcat, it seems that anything under 10 seconds requires a roll cage. Dodge has printed a letter that it received from the NHRA that stated that since a stock Hellcat did turn a 9.90 (or something close to that), that a roll cage will be required to race one.
I've got a buddy with a caddy cts that is deep into the 10s. the nhra doesn't mandate a cage since the car is newer than 08. i think that's nuts.
I dont recall the rule verbatim, but its something along the lines of cars faster than 11.xx require a cage unless they can run that from the factory, then its 9.99 and faster (dont quote me on those et numbers, I just know that there is a gray area where modified cars running a certain et require a cage where as factory cars running that same et do not). Of course a lot of it depends on who's doing tech. Ive seen first hand some rules get ignored by tech at certain tracks. I may or may not have first hand experience of a GSXR running high 9's at 140+ while the rider wore blue jeans (shouldve been in full leathers per NHRA rules). Ahhhh, to be young and invincible..... I mean, allegedly...
Roll BAR 11.49 and faster, roll CAGE 9.99 and faster......is correct unless the car has airbags. Airbags cars may run up to 9.99 without roll bar. 9.99 and faster need a cage. seat belts every 2 years, chute 150+ mph. All cars need a radiator recovery tank. You only "NEED" an engine blanket-diaper if you run an NHRA "CLASS" which requires one. (S/G, S/C, Super Street, TD, TS, Comp, etc.) Advanced ET 7.50 (4.50) is still the ONLY "time" related requirement for the blanket. Helmet... as outlined under Class Requirements, drivers in all classes, including motorcycles, must wear a helmet meeting Snell or SFI Specifications. Effective Jan. 1, 2008, full face helmet mandatory on all cars 9.99 or quicker. Anything faster than 9.99 need bar Certification, a license, and fire suit is needed. You must read NHRA rules book to confirm exact clothing along with steel underwear for those going over 200mph......LOL and a roll of TP. Long wheel studs for slicks...the thread engagement on all wheel studs to the lug nut, or lug bolts to wheel hubs, must be equivalent to or greater than the diameter of the stud/bolt. Length of the stud/bolt does NOT determine permissibility. ( a 7/16" stud must be thoroughly engaged through the threads in the hex portion of the lug a minimum of 7/16"). DRIVESHAFT LOOP DEFINITION: 360 degrees of enclosure,1/4-inch minimum thickness and 2 inches wide, or 7/8-inch x .065-inch welded steel tubing, securely mounted to the frame or frame structure where available (or to the OEM floor or rocker box where a frame does not exist) and located within 6 inches of the front or rear universal joint for support of the driveshaft in event of U-joint failure. Hope this covers your question. Fernando
Sure like reading that. Sure wish i was 24 again... WOW,,, that is insane no wonder ya need a lawyer !!!!
