Theo and Listers,
The image read surface temperature and as I recall just needed an
unobstructed view of the surface. Easily done from the front as he was able
to do a wide angle or do a multiple image pass really close with the camera
and have us just watch the video. We also videoed from inside the engine bay
and got a really good shot of the full surface of the rad. Our stock ...
dare I say it???...Camaro ...rad was a one pass rad based on the video and I
believe the Tiger one in my car is as well. But I would think that if you
add rows and or increase the ID of the core tubes you should be able to do
this as it is just a hydraulic system and will the pressure being pumped is
increased to the Rad outlet pipe it should not impact the pressure cap or
anything else. Why else would you put a high volume HiPo 289 water pump on?
What does everyone think???

Hi Tim,
How much did the presence of the plastic nose on the Camaro affect the
ability of the camera to 'read' the radiator? I think it's a great idea (I
remember seeing the van with the camera out at the track) but I think that
the Tiger's small nose opening and the fact that those are steel panels may
make it more difficult to get a good assessment of the rad efficiency using
the infrared camera.
If you make a multipass rad then you increase the flow restriction
geometrically, i.e. if you convert a single pass rad to a two-pass, you get
four times the restriction (half the number of tubes, and twice the length)
and for a three pass, nine times the restriction. Since making the Tiger
rad a three-pass is not too hard, what's the general opinion on flow
restriction? Is this a limiting factor for a three or four-row HE rad?
