Torque for blow-down (NHRA) valve?
Torque for blow-down (NHRA) valve? Anyone know the proper torque for the Nitrous Outlet NHRA valve (replaces the factory burst disc)? I want to say they told me 15 ft lbs but not positive.
Thanks!
Thanks!

Just a tip for everyone, my 2 cents.
When you put the line or tube on, do it finger tight.
I had a crew guy remove the line a few years ago and got a face full.
When someone put the line on, they put it too tight, and when he removed it, the whole fitting turned and released the N2O.
If it does pop, it won't leak anyway, so no need to crank the line/tube down that tight.
Again, just my 2 cents??
