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! |

http://210.101.116.115/fisita/pdf/H202.pdf Some numbers. SBC powered vans or pickups have the most capable cooling system for the duty cycles used.The sizes and flow rates for them could be marked as a maxima. A 1-1/2" X 96" hose will flow less than a 2-1/4" X 24",the pressures from a given pump similar to the Chevy's, Area of the radiator opening port,or facia must be sized to flow at average city speeds,40kph/25mph. A manometer check of the working air pressures is required to ensure the flows can be achieved without fan assistance. Equal pressures on both sides of the rad equals no flow,and the cause of rising temps. Vapour lock in the system is also problematic,a no bubble pipe and rad will cool better as the area of contact is larger. All of this has been sussed for decades,a different setup will yield different results. (IMG:style_emoticons/default/smile.gif) / A custom fan shroud,to carry the fan you have,so all the air passes through all the rad. https://www.youtube.com/watch?v=G8cz_5eP81U The number of 90* bends,in addition to kinked hoses,will limit the flow. / |
