Have any of you drilled your thermostat's? I am wondering if this would be beneficial for the 2LT. I have read where some who have purchased have an allhead head have "modified" their thermostat. Not sure where I read that, and there was no mention to what they did.
The pros that I can think of would be:
-pseudo "hi-flow"
-a small amount of coolant circulating the radiator at all times
The cons:
-modifying a thermostat
-longer warm up times
I am not sure if I am on the right track. Feel free to correct me or give any and all feedback. Just wanting to know if this is something I should do. I am in the US and do not want to import a triton 180 or 190 hi flow.
I doubt that will be a benefit. The heads crack long after the t/stat has opened. Some owners with difficult to cool engines have changed the drive pulley diameter to make a water pump spin faster. I don't know of it would help in this case or if its possible.
Yeah, I have opted to go with the lower temp (180F/82C) thermostat from gates. I am thinking about getting a larger 4 core radiator as funds allow. Regarding the pulley, do you think this could have negative effects with the increased RPM's? Im not sure what they would be increased pressure perhaps water pump malfunction? I like the idea of that though....
Others I know of that increased the rotational speed of the water pump only increased it by 10% or so. As far as the pump goes ,it would be like the difference between hwy speed and fwy speed.
