I have owned several 2v but this is the first I am putting nitrous on. I am going to put a NX plate kit that mounts under the upper plenum, but my question is will a 100 shot be safe on the stock 04 intake?
I have posted about this a lot over the years. I have run many many bottles through my cars stock plastic intake. From 70hp,90hp,125hp,150hp shots. All of which were wet. Meaning fuel and nitrous were sprayed into the manifold.
I have had two nitrous backfires. One blew the filter off and nothing was damaged, and one when I banged the limiter into 4th gear. Again nothing happened. Its been proven you can spray 150shots with a fogger nozzle without issue into the stock manifold. Over that you must run a plate kit. Nitrous express plate setup is known to do 200shots wet fine through the stock manifold.
A few people have tried 175hp shots with a fogger nozzle and after a few passes blown their manifolds out with a nasty backfire. So 150hp or less a fogger is fine, more than 150hp do a plate.
I can say that you will be fine. We do have a couple of safety measures that can keep that from happening though. Such as a window switch and a fuel pressure safety switch. Call us if you have any other questions.
