Hi Guys,

I've been running the Deli in 35°c temperatures for the last week and it really seems to like the warm weather. It seems more responsive and more powerful especially on hills and I've also noticed the EGT's are much lower. I assume the warmer intake air is giving a better burn hence less unburnt fuel in the exhaust gases.  This has made me wonder about deleting the intercooler, especially in winter. Anyone have any thoughts on this?

The warmer the air going into the cylinder the greater the amount of Nitrogen and less oxygen.

This leads to a greater amount of Nitrous Dioxide in the exhaust, which is an air pollutant. contributing to Acid rain. and not very good for passing pedestrians to breath in.

Colder air is more dense so you get more oxygen molecules in.  More oxygen means a bigger bang.  Thats why the have intercoolers.
