Bottom mount setups and the elements...
 

I've been wondering, how are/will the bottom mounts setup fare with snow, salt, crap and such we have in the winter?

Is it a case of "dont run it in the winter" or it's not that bad?

I have seen the JDM underbody plastics and such, not sure it would be a good idea with a red hot turbo under there.

Just wondering...

Cheers :burnrubber:

Have you looked at a stock one from underneath? They have a metal pan under the whole engine bay. The plastic parts don't start until behind the engine bay.

The Jdm under panels install over a solid surface more or less. There is nowhere under those panels to install anything. Most undermount kits install over the factory metal plate.

Ah, Makes sense, I had been trying to find pictures of setups with the metal plate back in place and did not find any.

Couldn't link the picture but google p tuning Frs turbo kit and you'd find a few pictures

I couldn't own a bottom mount setup in florida. Too much standing water from the summer downpours. It's not uncommon at all to find yourself up past your door sills in water all of a sudden. I can't imagine the havoc that could cause, whether from ingestion or just dunking a 1500deg piece of very precisely manufactured metal in.

There's a good reason you don't see many (any?) factory turbos mounted that low.

I wouldn't worry about a bottom mount. There is a splash shield, and the filter is mounted way up in the engine compartment, so you will be fine even if you drive through a lake which is I guess what Central and South Florida people do. Because Subaru rally car?

This ^^^^^

If you run into water deep enough to somehow damage the turbo, you'll crack the hot engine block in the process so it'll be the least of your worries. Porsche has been running a low mount single or twin oil scavenged turbo system in their 911 series for the past 4 decades without any worries of damaging the turbo. :happy0180:

Good call. I trust you've done your research :). I'd still be wary of ingestion, but I'm just paranoid like that.

Gotcha, if you're talking about water ingestion through the intake, that would be impossible with our setup since the filter sits up high in the engine compartment.

Bottom mount systems and a miss judged speed bump... They are all element proff. Rule of thumb if its air tight its also water tight

Honestly I wouldn't even worry about. OEMs even have bottom mount setups and I wouldn't concerned so much about water ingestion as much as thermal shock. The OEM setups have shown that thermal shock isn't an issue...just don't drive it into a river.

Not sure about PTuning (but curious) but the first bottom mount from accelerated performance was mounted higher than the frame.

If you're hitting the speedbump with the turbo WTF have you done to the body?
