Long time since I've been in the street section. I'm looking to add a compressor to my current nnbs. It's main use is gonna be for train horns and be able to fill tires. Haven't figured out tank size yet or exactly what horns. Should I figure that first? It also needs to be able to take mn temps and weather. I'm thinking the safest place for it would be under the hood in the spare battery location.

Any suggestions and help? I searched alittle but didn't come up with much for my questions.

My spare tire is still there but it doesn't fit either of my sets of tires. So it's useless. I saw a nnbs kit where the horns came with a bracket to fit under the hood and fire down but I can't find them again. I'm just worried with all the lake slush and salt that equipment would get ruined in the spare tire location.

That reminds me. I should sell the spare tire since its basically brand new and does me no god.

Under the hood is fine but expect for it to be loud in the cabin.

The horns or the compressor? Or both? I wasnt set on the horns under the hood. I'd rather have the compressor there. I just thought the kit was cool but I couldn't find it anymore and could easily fab up my own for cheaper.

LOL no just the compressor under the hood, If you have room I would put the horns behind the grill. But it is pretty tight there most people put them under the bed.

My old viairs were pretty quiet. Under the hood make that much difference?

Its mainly because that tray is bolted the the fender which is bolted to the fire wall on the driver side. So the vibration will be transferred. I would say just try it and see if its to loud our not for you.

Yea I'd try my hardest to isolate or rubber mount it off a secondary plate.

I run the Viair 20007 kit, the tank helps with the vibration from the compressor. With my stereo up a little I cannot even tell if my compressor is on or not.
