Hey guys it's Brian. My computer is temporarily down so I set up a new profile. I got my NOS installed today. WOW!!!!! It hits hard. I did a second gear full throttle romp and got majorly sideways! I left two 20' tire tracks in my wake! The purge out my cowl in two spots is unbelievable, even in this dry heat we are having they shoot about 8' in the air. I will post pics tomorrow.

Anyways, I mounted my NX relay and TPS switch under the passenger side dash to keep them away from the heat. I notice my relay makes a buzzing sound when the TPS switch comes on at full throttle. Is this normal? I even got a new one at the store, but to no avail, I get the same noise. I would imagine if the relay is mounted in the engine compartment you wouldn't hear it, but since mine is inside the cockpit, I can slightly hear it at WOT. Just wondering if there is anything I can do about it.

I had the same solenoid buzzing, after I installed my N20.
Check your solenoid ground wire. If you do not have a fully grounded connection, solenoids will buzz.
Try grounding solenoids in different location.

 

It is actually not the solinoids that buzz, but the relay. I will check it out the ground wire for it, and maybe hook it up to the main ground terminal near the battery.

 

Definetly check the grounding. I has to be a real good solid ground. Also just go over the wiring to it to make sure its hooked up just rite. (I dont know if it comes on a pigtail and a holder or not, thats why I state the last part)

 

It was the ground. Works fine now. Thanks.

 

Sometimes its hard to find a good ground on the C5 ;)
