I have used it in the past, and with BFG drag radials it didnt have any problem hooking!!!
won quit a few races against everything from cadillac's to S-10's with V-8's.
My solution to the cop thing was....a bag of nitrous from compucar. Its a dry system that is powered by your cig. lighter on a curly cord, activated by a pushbutton you hold in between your fingers....and has only one line (dry system up to 100 hp)......its mounted to a board in a gym bag.....and goes behind the passenger seat...(and which the passenger seat back all the way, and layed back a little......its totally hidden). the one line is nylon, and comes from the single solonoid...(which is where the jet lays)....
here is a link to it!

how safe is it?? safe as you are. we used our heaters in the winter to heat the bottle (room temp basically) and AC in the summer to cool it...yes cool it. After geting a fresh bottle it would be very hot...........I remember this one time, this buddy of mine and myself were trying to race a little going to the track........both our bottles had just gotten filled and both were to hot and at to high a pressure for the solonoid to work lol......after a few minutes with the AC blasting.......It was ON!
here is a few safty tips....
NEVER USE a BOTTLE HEATER without monitering your pressure and temp!
never spray nitrous on a wet street.......or in front of a cop!!!
Never engage nitrous while the engine is off.
Never engage nitrous while under a min, of 3200 rpm's
and my favorite.....
Never hook a nitrous system up on a street car with a WOT switch.....(thats just my preference....I'd rather use a pushbutton.....if trouble arises, simply let off the button.....)!
