Here is the cold air intake. 2 small wide holes. That come together in 1 big tube.
The total hole squire area of the 2 holes is less then the squire area of the big tube. The lintmeter is saying 2.5cm or 1 inch.


The air is succed from between the little space between the hood and the chrome part of the bumper. I think, the hole intake is a bit to restrictive...


Lets change that.

What do i think to win?
Better airflow in the intake, less backpressure beceause the turbo needs to succ les hard for getting the right boost.

A fast calculation. P&G at highwayspeed. Is around 1900rpm to 2400rpm.

Lets use 2000rpm. 1bar overboost. 4 stroke diesel. 2000cc. 4 cilinder. Thats so 2000rpm x 2l x 2 (boost) x 0,5 (4 stroke part) = 4000l of air each minute. = 4 m^3 of air every minute succed trough the intake. That needs to be good designed to work propely.

Hopefully the fuel economy will drop a little bit.

Photo of how it is now will be uploaded this eavening beceause i don't have a photo of it yet.
