Concerning the S1, some of the cars - including mine - came without the trumpet that aligns with the inverted louvres. So my air intake is directly over the exhaust manifold, wich i dislike quite a bit. I have spoken to MMC and also the manufacturer of the trumpet, but the part is no longer available. Now, Dave W on this forum has stated that the cars without trumpet seemed to rum better than the cars with a trumpet. How sure is this, and what could be the explanation? Anyhow, I would like to get more cold air in or at least not the hot air from the manifold - anyone with an idea of how this could be done? And would I really notice a difference.....
The reason is supposed to be because the airflow along the bonnet is turbulent. I've never run mine without the trumpet, but if I didnt have one, Id be tempted to take the air from above the radiator.
