ok,watched the videos and I agree with the low speed advantages with a shroud, but we dune and dune fast for rhinos...I wonder if this would actually slow down the air speed through the radiator making the fan do all the work at a higher speed,thus forcing the fan to cycle more frequently?? whats your take on my spun point of view??

I agree with you...question is where is the cross over point and how does throttle setting and ambient temperature change the curves...

1/2 throttle on a cool day at 50mph the shroud not helping imo...

Wot is under load is when you are generating the most heat at the source and the heavier the load the more heat that has to be sucked out...

20 mph at wot on a sand hill on a warm day is the most heat you can generate at the combustion chamber...that is when you need the most effective cooling imo...

Engine Ice is definitely a big help with that...and you really can't judge it's effectiveness by the coolant temperature...that is misleading at best...

At the radiator the shroud plays a different role...and you can judge it's effectiveness by comparing coolant temp difference from input to output with and with out shroud...

So all you have to do is run an inline sensor at the input and output and thru a switch to your coolant temp gauge...you don't need two gauges...you will be able to tell he difference if there is any...

I have done it...but not to test shrouds...but I have a shroud...not installed...and might still do it someday...

Hoping you will do it first and save me the trouble... :13:

I just put a shroud on my Rhino. I am heading to the dunes this weekend. This should be a good test as Glamis is going to warm. I am curious to see if it makes a difference.
