Since I am a coupe I am sure there is more to it. I did by a blowdown tube, but does it have to run outside of the car. I plan to put the bottle next to me in the pass. area

 

anytime the bottle is not seperated by a sealed bulkhed...it is required to run a blow down tube outside of the passanger compartment.

 

Is there any rules as to how the blow down tube exits? Can I use nitrous line as a blow down tube instead in the hard line in the kit?

 

Okay, here is the OFFICIAL rules for 2007:

2007 NHRA Rules - 12-27-2006

While it remains the responsibility of the racer to know the rules pertaining to his/her vehicle and class I would like to highlight some rules that will be enforced in the 2007 Season at Redding Drag Strip. It is important to note that there have been changes in the rules from 2006.

if you are using a flexible line it must use a bulkhead fitting to secure the exit end

this prevent the line from whipping around in the case of a burst disc rupture

 

Summit has racing jackets for pretty cheap.

Here is one of them

 

so say i go to a test n tune night. am i gonna need all this stuff?

bottle is mounted right behind the pass seat.... no blow down, no helmet, no jacket..

no race?

 

.

A decent track or racer will not race without the proper respect for himself & other drivers. A cockpit full of N2O blowing around will not be fun, or safe.

.

 

I completely understand but damn. I have spent at least $500 in safety to make sure I protect the engine now I have to concern myself with me. HAHA. Damn I need to figure something out.

 

well crap. im gonna be *really* upset if i drive 2 hours this friday and i cant run my car.

got an idea.. throw my bottle in trunk of my friends car then install it after tech!

 

no no no !

 

well i guess ill spend the 50 bucks to go dyno my car. off spary, on spray, and simulated 1/4th

The #1 jacket is ~$50-60. If you're in the game, you're going to pay to play.

I would do what you have to do, but a tip, don't waste a bunch of money buying the minimum safety equipment. I would never buy a #1 jacket, and I yell at my friends when they do. Buy the 9.99 stuff, it's better, safer and will last longer than the bare minimum stuff. A big item guys should all have, GLOVES. When I was on fire, you need your hands to get out and trust me, very cheap insurance. Good luck guys.

if you wear a harness 5 pc, in your race car always make sure it is pulled tite in the shoulder straps. you don't want to be moving or leaning over to the side should something happen. you can lose control of the car,if you can't see where your going even for a second. pull them shoulder straps tight.......ask me how i know................RON
