So what is the biggest Viair compressor I can get in twins? I’m still waiting to hear back about my Zenith OB2, I love my horns and it sucks when the compressor won’t go over 75 psi. Thank you for all your help.
For the fastest fill rate go with an Oasis compressor. 
^^He speaketh the trutheth.
If I had a spare $1300 laying around trust me it would in the bed of my truck.
That’s why they invented credit cards…LOL
This is true. I have a feeling I will be ordering an oasis xd 3000 compressor for my truck.
It will also run a 1/2" impact so you can change a tire and air up a spare in a hurry.
do you have to add batterys or whats it take to run a oasis?
That depends on how long the compressor needs to run. They typically draw 150 to 160 amps. An Odyssey PC2150 will run our compressors about 10 minutes without a charge behind it before it starts to lose voltage and the compressor slows down. You can get a lot of air in 10 minutes since it takes less than 1 minute to fill 5 gallons to 150 PSI. Then your vehicle will need enough time to recharge it. If it doesn’t have enough time or you run the compressor longer than 10 minutes then you’ll need a high output alternator.
wats the price on your Odyssey PC2150? guess it will work on 10 gal tank
