Blowdown/Vent Tube

Is it required to have a blow down tube to race? Friend of mine said it was so, but I thought as long as the bottle was seperate from the passenger compartment it wouldn't be neccessary. If you do need one, where's the best place to get one? Thanks

It still may not be a bad idea, remember 3000 psi, pops the safety thingy and 6000 psi the bottle goes BOOM

The disc for the blow down/pop off valve will allow the bottle to release the nitrous into the trunk area. But that is not allowed in the passenger area of the vehicle. That IS not legal. BLow down tube only allows that same blow off valve to release the nitrous outside the car into the air.

If the bottle pressure is too high and the pop off valve don't work, the blow down tube is worthless and wont matter anyway!!!!!! If all is correctly installed that should not be an issue.

So as long as the tank is in the trunk sealed away from the passenger compartment by the rear seat so as no nitrous will enter the passenger compartment, it is leagal to run at the track without a tube?? I'm trying to follow you here but I'm having a bit of difficulty...

thats right. you dont need the blowdown tube unless the bottle is in the passenger compartment.

Here's a question, and my reasoning for wanting a blow down tube, even though my bottle is in the trunk.

If the safety circle or whatever the hell it's called blows @ 3000 psi...Can't it damage my stereo equipment in the trunk; (ie) amps, subs.....or anything else for that matter.

It could I suppose, if something actually blows from the tank, but I think that the safety valve is some what contained on the valve.

I mean the nitrous oxide itself..........not the little circle

Can't the huge drastic change in temp or the nitrous ruin/freeze stuff....

I had one blow years ago. When I opened the trunk, looked like I had an overgrown Popsicle growing in the trunk. (White Bottle)

As long as its pointed away from everything it would be alright but to be safe you may want to put in a tube. Your call.

Just put a case of beer back there so it won't be a total loss. You can kick back and have a REAL cold one while you're waiting for your amp to thaw.
