How many rows on your rad... and does it work okay?
Discussion
I’ve had a post running about my rad not working as well as it did before and could not understand why... but having pulled it out yesterday I’m now starting the think the core is too good!
It does not loose heat (in hot weather) as well as my old one under normal running conditions... but put the fans on and its pulled down okay.
Looking at what I have, its a 39 row, 3 core staggered unit and if mounted straight up and down, I think it would be a cracking rad... but I think the problem in the Griff is the angle it mounts at and the restricted inflow... I think its hitting the rad and because it’s so dense with its staggered 39 row construction, Its not allowing air to pass through it as it should?
I have a splitter so that will help, but I just think the things too good...
I have an old unit I got to mess about with and this is 29 rows, 3 core and inline and is the standard fit by TVR I think...
So, how many rows do people have on their rads and are the in-line or staggered units
Would be good to know if anyone has their rad out.. and also how efficient they are in losing heat... I'm coming to the conclusion that the rads with more cooling pipes in there may actually be detrimental in the Griff application... but obviously there will be an optimum.. did TVR get it right maybe

Hot air rises, the griff rad fitted at a slant is only going to make the cores work better. Can't see 'over crowded' cores causing the problems you are describing.
Your inlet position means you are only using@ 2/3's of the rad ~ so say effectively 39 (*2/3) = 26 cores.....
Just put the inlet back at the top & re-route your damned induction. That nose filter is crap anyway ~I'd go back to the early version with a proper air filter in the nose only need to saw a big hole in the inner wing...

Cooling systems on TVRs make me smile, on one old chimaera I had it would not behave at all, regardless of what I changed, it would always run hot. In the end I put it down to a rap gauge
On another chim, that rad was like Swiss cheese, missing so many fins you could see right through, I bought an alloy replacement but the car ran perfectly, would sit in traffic all day no issues with the Swiss cheese rad
Don't we just love TVRs lol

Right just had a look. Same core as yours 39, 3 row staggered. The centre of my inlet is about 2.75" from the top of the main rad. Now looking at it i also had my outlet moved up slightly to stop the hose going into the anti roll bar bracket. This to the centre again is about 2.5" from the bottom of rad.
Just out of interest where abouts is your splitter positioned. Is it as far forward as you can get it. Ie right on the edge of the large opening.

You want to see how dense it is Dave.. you can hardly see light through it 
And I'm not going to chop a huge hole in the wing... I like my car standard
Will move the inlet back though but TBH I can't see why that could cause the problem.. look at house rads, they are fed bottom to bottom
Ian.. my top inlet is 5" down (to its ctr) and the bottom one is 1.75" up ?
and the splitter looks like this :-
And yes.. what would we have to play with over winter if TVR's had never been invented
.... very nice Taimar BTW Glen

I have put my splitter a lot further forward than that. Right on the edge of the large opening. To my mind, placing it further forward will help ram air into the rad. As in Petes car in this thread.
