winter boosting

[evilfred]

I live in Quebec and i think about turboing my d16.

One thing i was wondering is any of you are running there setup during winter?

waht special care you must have to do so?

You may want to lower the boost a bit or dump a bit more fuel.

Doh !

[evilfred]

why lower the boost/add more fuel?

why lower the boost/add more fuel?

cold air is denser than hot/warm air. So as the air gets colder, the turbo is actually forcing more air into the engine than normal. The car probably wasn't tuned for this. So to be on the safe side, you either need to back off on the boost, or raise the fuel a little to accomodate the extra air.

For someone running 5-6psi, this probably isn't anything to be concerned about, but for people running more, they may need to adjust.

yeah i just found my answer on the other board i was coming back to tell

but i also read that since the air is colder it as less chance to detonate?

[kommon_sense]

true, cooler air is less likely to detonate. However, if you don't have enough fuel, then you can end up running lean which leads to detonation.

For winter i know it is recommended to check fuel ratio carfully cuz it may be change because the colder air.

So i could turn he boost down a bit.
my questions is would it be a good idea to remove the intercooler et install a straight pipe. My point be that there is no need to get the air cold since it is already, but also i want to prevent from breaking it with ice and snow.

just install a nylon cover over the ic.
