Autometer, not Autogage, are American made. Summit or Jegs private label parts are meant to undercut the well known American names prices. They are usually a good copy, but may be foreign made and may be less quality. JMO. I Just bought a Jegs power valve installation tool. It won't fit some power valves or block offs. Have to enlarge the grip point a little bit. Bet it is foreign made and no quality check for fitment. I think you get what you pay for.
That's kinda the idea I was having. I know some of the JEGS and Summit brand items are good but some can be cheaply made or foreign. In the past, I've asked Summit who makes their brand fittings and hoses twice before and they won't or can't release that info. Kinda makes you wonder....
I'm just looking for ways to get better at bracket racing and figured a digital gauge would be a step in the right direction in order to be consistent as far as trying to get the water temp the same every time that I go out. My current gauges work fine, just figured accuracy might play a role in this game.
I know you're looking for digital gauges but at least for water I'd consider a mechanical analog option. Especially nice when going rounds in warm weather. It always reads with no power needed so it's nice to poke your head in the car and see where you're sitting temp wise.
OP, people have been winning drag races/bracket races for many years with deadly consistent cars with good quality mechanical sweep gauges . Like 65StickStang above me said in post # 8, its nice to just take a peek at water temp when sitting in the pits. IMO spend your $ elsewhere
