BMR radiators / overheating.

Last year my Dale / Griffin radiator cracked and I replaced it with this one from the BMR in the UK:

this week I was going to take the tiger out for a run over some mountain passes but after about 30 minutes, no traffic, it was running at over 100C / close to 240F. I returned home and checked everything over.
1. Full of fresh Evans waterless coolant.
2. gauge is mechnical.
3. horn holes blocked, along with gap between rad and crossmember.
4. fan shroud in place with 13" flex fan on water pump hub.
5. doesn't overheat at idle even when left running for 30 minutes.
I've NEVER had a problem with overheating at speed before. the only issues I had was a idle, traffic, slow speed but even those had been solved by all the above. engine is a 490hp 347, but wasn't a problem before.
everything is pointing at the BMR radiator just being a bit crap and not doing as good a job as the Dale rad. anyone running one of these?
