Just wanted to know what is best or if one method is better than the other?

Dp exiting on driver side- Stays away from the radiator as much as possible.

DP exiting on passenger side- Pretty close to radiator.

For either scenario above, does it really make that much of a difference to have the DP exit to the Driver side or passenger side?

And if you have the DP exit toward the passenger side, close to the radiator, will this potentially cause heatsoak to the radiator?

 

i doubt it'll make that much of a difference. it all really depends on which way your turbine faces.
