Cage Requirements
ive gone a best of 11.20 @ 126, and thats on stock 10 bolt, and stock suspension in my six speed car, and i know after i do a rear end and suspension that it will be in the 10s, and on the bottle it should go into the nines and trap well over that 135 mark, so i know ill need the safety stuff, but i would like to know how hardcore it needs to be
For 2007 you only need a 5-pt roll bar. I haven't heard anything about a change. Maybe someone else can confirm. Here's a link to the NHRA FAQ:

YEAH alot of horrible info in this thread.
The above is correct for cars running faster then 11.99 for IHRA and 11.49 for NHRA.
A 5 point is all thats needed Rollbar wise.
11.999 IHRA / 11.49 NHRA
1. single layer fire jacket is needed.
2. Helmet
(Snell 95 or SFI 41.1A min.)
3. Bellhousing (SFI 6.1/6.2)
4. Driveshaft Loop or any time a slick is used at ant ET.
5. Flywheel/Clutch (SFI 1.1/1.2)
Now for NHRA it changes again for many things at 10.99
1. Aftermarket Rear Axles are needed
2. Harmonic Balancer (SFI 18.1)
3. Master Electrical Cutoff (135mph)
4. Transmission Shield (SFI 4.1)
Then for 9.99 and quicker...
all the above plus a 8 point cage for non modified firewall cars.
1. Double layer Pants and Jacket (sold the old jacket wont work)
neck brace, double layer gloves, shoes
2. Auto Trans Flexplate (SFI 29.1)
3. Driver Restraint System (SFI 16.1)
4. Flexplate Shield (SFI 30.1)
5. NHRA Competition License
6. NHRA Chassis Sticker
7. Parachute @ 150mph
8. Window Net
Its all right on NHRA's site under there Quck Ref E.T. guide

what consists of an 8 point, ive never been this fast to need all these safety features.
and i need a master cutoff at 135? where the **** does that go, on my fender? my battery is still up front
Good job finding the info. I found the quick guide but I could not find the break down on the cages which is what I was really looking for.
BTW the switch has to go on the back of the car
I've seen a car roll and some one get tossed out of the window, window net, neck collars, fire suits and things might be a hassle, but they help prevent your death, I would just get a little extra if you're going to race the car.
I have posted this before I guess no one noticed


High Amp Alternator Shut Down Relay Kit
P/N - 764-50105
This kit, comes complete with 250 amp solenoid and two 10' sections of 8 gauge wire, will effectively handle alternator feedback of the highest amperage alternators. Eliminates engine run-on when the master disconnect is turned off.
No one said going fast was easy. if it was everyone would be doing it
****, maybe ill do the trick with the taillight and go through that and have the push pull style switch and swap it out to a normal light for on the street.
i need to get me a rulebook, to see exactly what i will need for a cage, and my john force lookalike outfit, lol

The only reason that looked so bad is because the fuel pump was still on. Now think how to put that out before you can turn off the pump, you cant or you wait for it to run out of gas.

Sorry for getting a lil preachy, but NOTHING is more important than youre saftey period.
