hi Guys,
I thought i would buy the Tridon hi flow thermostat and see what results i would get v the modified unit.
The Tridon hi flow thermostat, TT297-180, which is listed to suit my 2013 Mitsubishi Triton dual cab turbo diesel.
I had also had the original OEM that came out of my Triton.
So, in the end i had both.
According to Tridon packaging and info on the part number list, this unit is a hi flow and has 30% extra cooling flow.
Since i had both side by side, i was trying to see how the Tridon flows 30% more.
Looking at both units to compare:
- the valve opening area is the same – so no adavantage here
- I put both in a pot and slowly brought to a boil.
- both opened at the same time
- the OEM actually opens further due to its design where the rear support bridge is square and the valve when opening clears it.
- the Tridon unit opens as far as it can, which is basically up to where it stops up against the rear support ‘bridge’ – as the bridge comes in on and angle.
- once the valve opens, the Tridon unit flow is hampered by the thicker front support ‘bridge’ as it is wide and flares open a little.
- the OEM unit front support ‘bridge’ is narrower and is higher and further away, which to me is less restrictive.
-once the water starts to cool, the Tridon starts to close earlier, the OEM stays open longer.
My basic understanding is that the OEM would actually flow more than the Tridon hi flow, let alone the Tridon flow 30% better than the OEM unit.
I have sent Tridon email asking the proof to how their unit flows 30% more after looking and experimenting myself.
very interesting??
