Mk3 Thermostate Question

Don't remove the t-stat. Don't play with your timing after you get it set to where you want it. If you run rich all the time you'll be removing the entire intake to maintain your plugs.

Do Not remove the thermostat.

Listen to what these guys are saying to you.

Yeah don't remove that thermostat. The thermostat not only regulates minimun operating temperature, but flow also. You will totally screw up your cooling system by running without one. Use a 160 or 180 degree thermostat.

How do you know it runs as hot as 220? Do you have an aftermarket gauge?

My aftermarket gauge ran at 190 all day today, actually I couldn't get it above 190 even under boost. Mine normally runs around 195-200 at its hottest with a 180 degree thermostat, stock radiator, new waterpump and a new fan clutch.
