I removed my thermostat in order to reduce engine temp. I find that it does benefit provided the engine is tuned to take advantage of it. Cause I find that I can run slightly leaner and advance ignition a bit. Engine also feels more lively.

Engine now runs around 70C instead of 85C.

Running without the unit is quite common practice in Malaysia -esp. taxi

What is supposed to be your optimum running temperature? Running too low will accelerate wear.
I did run without thermostat in my old car last time but on rainy days it kept at a low temperature the engine was sluggish. I think better off using a lower temperature thermostat.... :driver:

Helo everyone!!! Just a newbie on car...I got this Mitsubishi Lancer 4g15 12v SOHC with c62 body (A month ago). Engine is still in great condition but it lacks power. I went to the mechanic and had the clutch assy replaced with aisi disk and excel pressure and release bearing. Even the timing belt was replaced and valve tuned. However on long drive, my car jitters on 1500 rev especially during gear shift. Could it be a defective clutch disk?
Another thing, may i ask what could be done in...
