Reply to "Air volume"

First off @Adrian R. welcome to the madness!

Forgive me if I’m making assumptions, but as a newbie here, sometimes we inadvertently ask the wrong question for the right answer we’re seeking. I was a newbie only 6 months ago and I sure asked far too many of the wrong type of questions before working out what I really wanted to achieve. In this case, I’m assuming you actually want to know ‘How can I prevent my car from overheating’ ?

Although many of the suggestions above will help get more air into your engine bay, I would suggest there are things to check first before going down the path of forcing greater air induction. As @Michael Pickett says above, ‘It’s all about the oil temperature’.

1. Do you have a full flow oil system? A separate oil filter will make changing oil easier as well as offer better protection for your engine, and a separate oil cooler will probably be the best investment in keeping your oil cool.

2. Do what @DannyP says and get rid of any chromed tinware as it doesn’t shed heat quickly. He’s also a big fan of dogsled tins, so ensure they are fitted to help direct the air correctly.

3. Everyone will tell you to ensure the hot air coming from the bottom half of the engine doesn’t mix with the cool air coming in to the top half, so ensure that the engine bay tinware is a good seal.

Before you get too involved in more complicated mods, I personally would do the 3 points above and see how hot the engine runs. It may be enough, or it may not. If it is, then you’ve saved time and money. If not, then you can look at further options. All our cars here are different in many ways, even if outwardly they look similar - engine size, gearbox ratios, extra capacity oil sump, full flow oil cooling system, tyre circumference, where we live (e.g. cold England vs hot Florida) and how we drive our cars all determine the amount of cooling required. Good luck and enjoy the journey!
