116HDi · 11-26-2021, 06:58 AM

I heard a lot of contradicting claims concerning equal length headers used in turbo engines.

Some say the equally spaced exhaust pulses will get the turbo to spool up faster and improve efficiency, others say the heat loss over the longer headers will lead to less exhaust energy to reach the turbine wheel.

Couldn't the second problem be solved by insulating the headers and reducing the heat loss?

What are your thoughts on this? Or does anyone have experience with such a modification? Looking forward reading your comments!

If it is of interest: The engine I plan to add this mod to is a 2014 DV6 (1.6HDi) with 115PS
