Help, I'm searching for a formula

[Baerformance]

Hello,
I have the values and the results but not the formula, can someone help me with my problem?
1. Values: 165°, 205cm³, 14cm, 312mm², 510mm² Result: 3,96
2. Values: 150°, 210cm³, 17cm, 345mm², 590mm² Result: 4,525

Both are calculated with the same formula, it's a formula for the intake.

I can try to extract the formula for you, but I'll need at least three more data points.
More data points would be even better.
