If lower is better, what would happen if the Tstat was removed and water was allowed to flow unhindered?
Not to hijack, just to understand better.

No problem
I like that attitude. I can see your ratcheting it up bit by bit.
I did take the thermostat out of my old 6cyl bmw cs coupe a long time ago. The problem was it never really warmed up. In fact it was down right cold, in the blue at speed somtimes.
With alot of trial and error, I think 3, 1/8th" holes through the thermostat gave me the temp I wanted (140??...maybe?). To be honest though, I didn't really notice a diff. Only that as db said, it took a little longer to warm up. I guess we're talking 5 hp here? I built the whole engine and tweaked quite a bit. 5 hp just might not have registered.
But, I think I agree with db, It's used to be, and I pretty sure it's still true to a degree, only when the engine was warmed up and running within a certain temp window that all the moving parts have expanded and fit together correctly as designed (we hope). So in a way I think driving around a cold engine is just as hard on it as driving it to hot.
Anyway, pop in any time. I'm the hijacker here. Till I arrived this thread was about changing a water pump. PK
