porting thermostat housing

[j-jamrod]

do you guys have any pictures os a thermostat ported or a ported watr pump, i heard with all this work the engine keep the temperature more below ,and the hot coolant go out faster , and get faster in to the engine, thank you for your help...

Just buy a cooler thermostat. Don't waste the time and effort for no real gains.

You need to work on your spelling and sentence structure. I can hardly read what your trying to say.

Just what will a lower temp thermostat do for him to increase the cooling rate of the cooling system?

a cooler t-stat will cause it to open sooner helping keep everything cooler. im running a 160 and love it

I haven't looks at the thermostats on the 2G's but on a 1G the factory part has a much larger sized hole/valve than most of the aftermarket ones. You might want to get a OEM part before modifying anything.

It will allow the coolant to flow through the engine at a lower temperature therefor having cooler temps. The stock flow of the cooling systems in these cars are effeciant enough for 700hp from what I've seen personally. You could also run a higher flowing fan to keep the temps down as well. Even if the water pump and waterneck were ported, the coolant still has to flow through the same size waterpipe and restrictive galleys throughout the block at the same velocity. I dont see the point either when there are easier ways to keep the temps lower. I have never heard of anyone doing this....even on another vehicle.

Do you just wanna do this just to do it or are you having coolant temp problems that your trying to remedy?

Well for one you cant "port" a thermostat and expect it to do something. You can port a water neck but that wont really do you any good. If you want to move more water quicker and help keep it cooler you will one need a better flowing radiator, and you will need a smaller pulley on your water pump. Using a smaller thermostat will help keep the temperature down without the need to worry about all the extra nonsense for no real gains.

The thermostats, both stock and lower temps, are open at operating temps. They have no relevance to cooling capacity beyond the fact they do limit coolant flow relative to the piping near them. Your 160 thermostat is doing nothing different than a stock 180 deg thermostat on a car whose operating temps are 190-210 or so other than opening sooner during warm-up. Their purpose is for engine warm-up, and once past their opening temp they're out of the equation, except that their holes limit cooling flow which the op is wondering about.

I don't understand where the idea that a lower temp thermostat improves cooling capacity in our cars, or any cars for that matter, when it has nothing to do with it whatsoever.

Well, to his question about "porting" it will do NOTHING for him. It is a waste of time and effort on a stock cooling system. If he wants to move more water, or quicker than he is going to need a better radiator, better fans, and possibly a smaller pulley on the water pump.
