Borgwarner EFR

[Gord R]

Hi,

Has anyone had any experience with the latest borgwarner EFR range?

Been watching these for a while, but would be interesting to see if anyone has any experience of them?

I tried using the match bot to suit it to the 4e, not enough cfm for it to run within the efficiency range even on the 6255/6258 turbines. It's just a little bit off and I'm pretty sure there wouldn't be much difference in terms of feel and performance

I haven't matched a 5e though
