Can anyone divulge details on the Renegade Hybrid radiator system such as dimensions, Inlet and outlet sizes and rad type (number of rows, if cross flow etc...). Is it even allowed ;-)?
This hot summer has proven that my system cannot handle it. I have some good components such as a 2000 cfm, 9 blade fan out of a Ford Taurus. The remote mechanical water pump is a standard R.H. unit. I also have a Griffin radiator, model 125241-H... no radiator cap (inlet=1.5" and outlet=1.75"). https://www.summitracing.com/parts/gri-1-25241-x The dimensions are 16"x 27.5" x 3". it is a 2 row unit. Although the inlet/outlet sizes are different, the hoses carrying coolant from front to rear are all the same size at 1.25 inch diameter. The Tech rep at Griffin seems to think that the rad should be fine but I ain't no 4 core unit either. The other part of this is the car has a Chalon kit installed. I question whether the bumper opening for rad air is sufficiently sized. The opening is ducted to the bulkhead opening. The inner fender walls are fully open to allow the air to exit. From all that I've read; the viable solutions is to either go with a RH rad setup (or as close to as possible) and/or go with an electric water pump. I think I have some (most) of what RH would sell me as there rad kit. The only difference I can see is the rad size/type and the bumper opening size. Pictures of my current setup can be found here: http://www.914world.com/bbs2/index.php?sho...132273&hl=# I feel like I am close to getting this figured out. Just a bit more tinkering is needed. Thanks! |

(IMG:style_emoticons/default/biggrin.gif) In and Out holes. (IMG:style_emoticons/default/smile.gif) A handy and necessary device from 100 yrs ago. (IMG:style_emoticons/default/evilgrin.gif) The header tanks are there only to be a place for the steam to go,the highest points. Large flows through the header tank is not needed,merely a path for steam. A one line header tank is also functional,as is desirable at the front. A sight glass,or plastic tube,may be temporarily installed to determine the rate of steam accumulation. Taking a long drive in heavy and hot conditions will stress the system,building steam in the top of the rad. Make certain the pump and pipes system can flow the minimum LS cooling flow,~55-65+ gpm. A decent copy of a truck's cooling system is a good start,other than the remote radiator,pump and restrictive pipes. Build your shroud to pull air through all of the radiator,make certain the airflow at 20 mph is sufficient. Use a manometer to check pressures fore and aft of the rad,then calculate airflow. A checklist of changes from stock configuration will point to errors,as the design has been well flogged. A 55 gal drum should be filled in less than 60 secs,at maximum,by the pipes and pumps used. Running @ 2K rpm,a flow of not less than 20 gpm is necessary to cool the LS. Reducing the diameters of the pipes will yield a smaller,and hotter flow. Stick to the LS thermostat,setting the operating temperature,and flows. https://www.google.ca/search?q=ls+water+pum...water+pump+flow https://www.google.ca/search?q=manometer+cu...anometer+custom https://www.google.ca/webhp?sourceid=chrome...=thermodynamics https://www.google.ca/webhp?sourceid=chrome...al%20conduction https://books.google.ca/books?id=y1XuAgAAQB...ics&f=false (IMG:style_emoticons/default/idea.gif) (IMG:style_emoticons/default/biggrin.gif) http://ecomodder.com/forum/showthread.php/...sure-21680.html / The Python look,to cool an LS.Anything else is just skinny,not cool.
