I had BES compare the BOP & Polar to see what would work best & the messaged me last Friday saying they would use the BOP.

Good info thanks.
Sure wish someone would make a good race intake for us, something similar to the BOP would be nice

Preston @ BES originally said he thought the polar would work good but after having them side by side he said the polar just didn’t have enough csa.

Ya I've owned both and the BOP has more potential without surgery imo. Glad Preston agrees with my thoughts.

The Polar Wind was a great idea. Wish it would've been made with a removable top and more material around the the runner entrance.... It'd save a lot of time over re-working a Victor or chasing down a BOP.

Oh there’s still going to be a surgery involved with the BOP just not as extensive I don’t think. I ran the BOP intake with my older pro ports so I was ok with his decision.

Has bes said how much hp they expect this topend to make and be reliable like you need?

They said they made 1170hp with a set of the big port heads like I’m getting on a 550 c.i.. That setup had compression around 16.8 & I want to stay around 15.5-15.75
