dual quad nitrous !!?!!

Its all in the tune up, 150 shot with a good tune up can be run on any motor. Built for nitrous or not, too much timing is what kills parts, pull a little extra first few times to sneak up on the tune without breaking parts. I have ran 3-4 bottles through my 340 dart that was not built for nitrous this way. And just like anything else, parts do add up on top of the system itself. Especially if you are maxed out for RPM at the stripe running NA, a gear change or taller tire maybe needed with nitrous.
