I going to shoot NOS to my Lq9 with ported 243 heads and 85 mm TB and intake.
Now i have a NX MAF kit but i think that the NX MAF housing can make a bottle neck . You think is better to use a plate sistem or fogger nozzel kits in place of the NX MAF kit?
If you have an opinion on a specific kit please explain your reason .
Thanks

 

I used the NX MAF kit on my car when it was stock. It actually worked quite well and by design sprays the nitrous in the centerline of airflow. In the past have used a nozzle and it worked well too. The nozzle is probably about the same as the NX MAF kit. The plate is the best though.

Keep in mind if you try and shoot nitrous BEFORE the MAF via nozzle, you are going to lower IATS and get too much spark advance.

I just tried the HSW Plate, but not enough info on it for me to trust it. Car ran ok. I'm am going to the NITROUS OUTLET PLATE next week. It is my opinion that the NO plate probably distrubutes the mix better than all of the others except a direct port.
