My name is Russell Posted September 3, 2009 Share Posted September 3, 2009 Can you have to large a diameter? Iv just scored two lengths of 45mm OD pipe that i was going to modify for taking coolant from the rear of my engine to the front but wondering if it would mean there is just to much fluid and the water would just stall intern giving poor flow through the radiator?.

Simon Posted September 3, 2009 Share Posted September 3, 2009 The water wont stall but it will move slower and still flow the same volume per second. Would you believe that the pressure will be greater in the larger pipe? Believe it... Quote Link to comment Share on other sites More sharing options...
xsspeed Posted September 3, 2009 Share Posted September 3, 2009 static pressure that is but yeah same volume flow rate, lower velocity. kinda hard to say whether it will be an issue or not without knowing what pump/flow/original pipe size was.

Static pressure is constant between diameters, its when it starts moving that pressure changes. Nothing to do with the question though haha. It should be fine, iv seen some very ugly cooling system set ups and they worked ok. Will you be replacing a smaller pipe or using it because you dont have one already?

xsspeed Posted September 3, 2009 Share Posted September 3, 2009 will the pump not maintain original pressure and so as velocity pressure has decreased static will increase? Quote Link to comment Share on other sites More sharing options...

Gaz Posted September 3, 2009 Share Posted September 3, 2009 More water holding = win IMO. When I was having cooling issues an old cunt told me that when they used to mod cars they would try get as much length in the pipes as poss so they could hold more water which in turn stayed cooler. He didnt mention larger dia pipes tho sorry. Whats original dia of pipe on the Fe3's? Gaz Quote Link to comment Share on other sites More sharing options...
Simon Posted September 3, 2009 Share Posted September 3, 2009 will the pump not maintain original pressure and so as velocity pressure has decreased static will increase? Oh we talking bout different things. The velocity only changes in the section of pipe with the different diameter. I dont think the pressure at the pump would differ enough to make a difference. I was talking about Just a random equation that enplanes venturis / fluid flowing through different diameter pipes. Conclusion: Do it, will be fine as long as its all sealed Quote Link to comment Share on other sites More sharing options...
