450's do 150psi max.. mine fills one 5 gallon in a little over 2 mins...110-145.. so 2 comps and 2 tanks should be the same..

I did some buisness with viar and got the hook up with 3 450's (wish 480s were out then). The amount of current that they draw is absolutly rediculious. I have a 160amp alternator, (which is getting send back because the bearing is squeeling when the compressors kick in), yellow top and the big three upgrade and my volts still drop when they kick in.

One of these days Im going to get an edc.

i think they draw around 23 amps per comp... i dont know if it changes when you add more then one...

It does.. So multiply that by 3, and that's how much current his compressors should have been pulling max.

Which isn't a whole lot, considering the alternator he has. My guess is, the alternator is bad. Cause it should be able to keep up, unless he didn't upgrade the wireing.. (the big 3) ..

0-175: about 5min 4sec
110-175: about 2min 37sec

I see Matt did this already lol oh well,

I got,

110-175 10 gal (3) 450's 2 min 58 sec. 60amp 0-175 10 gal (3) 450's 5 min 10 sec 60amp

May I add please do not run them to 175PSI!

That is like running your motor into the red line every time you drive it.

You are sitting at 4 min 27 sec now at 40amp with (2) 450's
so by adding one compressor you gain 2 min 21 sec. at pull an extra 20 amp

so that is 7.05sec per amp

I was just wondering why 450s should be run to 175. I have a 12 gallon with 2 450s at 175 psi and they never get hot even though it takes a while to fill.

Excessive brush wear and over amp draw.

they will lose time from there normal 400 hour service life. and pull more power.
