Maybe like @ Ultramaroon, I need to go bigger. |
I hate the HP recommendations because it's such a blanket statement, it's slightly triggering really.
It only comes down to btu/hr, that's how anything should be decided.
The issue with a 134, IMO is the minimal width of each row, that is simply going to reduce the cooing effect.
Even if you look at the 134, it's a 34 Row Cooler but listed at 21-27kBtu
A 915, even though "rated" the same HP Wise is rated at 27-37kBtu
You can even see it in the pressure drop across each core. Lower pressure drop is less effective fin area for the oil to travel and transfer heat.
RE: The HP Rating - IDK how you can market the 50-172 core as 600+ HP when effective BTU/hr is 40-60k
A comparative Series 9 that is 400-475 HP is 42k to 60k Btu/hr
Anyways, I ended up going with a 50-920 Core similar to Harrop's design. No thermostatic oil adapter so I constantly flow through the core regardless of temp. Depending on that adapter you can see a large oil pressure drop.
