What to remove in engine bay to help heat soak?

AlphaSnacks · 07-22-2012, 01:34 PM

I read a thread, which I can't find now, where someone mentioned that removing a few pointless plastics in the engine bay will allow the built-up hot air to escape faster and easier, thus minimizing the heat soak that is such an issue with our cars - especially when the weather is warm and the sun is out.

Does anyone know what those pieces were?

One thing I'm also very likely to do is cut ports or vents into the undercarriage plastic to allow for the heat to escape from the bottom of the car, as well. I've also noticed that heat soak, and by association, some loss of power occurs only when the sun is out, so if there were an effective way of allowing the engine bay to 'breathe', it'd surely help the issue quite a bit.

Get the fan control tuning from Uprev, its keep my oil 10-20 degrees cooler mostly all the time, especially in stop and go traffic.

I have all of that done, that's not for heat soak. 19R + UpRev + Fan Control

That kind of stuff does not fix heat soak, though. You still need proper ventilation to allow heat to escape.

Aftermarket vented hoods the only solution I see

i took off the rear rubber seal and in the middle i snapped off the small plastic piece that covers the wiper blades to allow even more air to escape. There is still some rubber seal in front of the battery cover and brake fluid cover it's "needed" to absorb any NVH for the hood - otherwise you'll notice the hood shaking. I also added a trailer side vent (to let air in( to the rear of the under-shroud. This was all good for a ~10 degree drop while cruising on the freeway. credit given to modshack - look in the diy section "air cooling for your sump".

I haven't experimented with taking off the engine cover - that might help. The above did seriously help though and the cost and time was minimal.

Leave the lower engine-cover off for a couple days after your next oil change. Then report your findings. Do this before you start cutting it.

IIRC the lower engine cover provides some rigidity to the front fascia. Driving around without it you risk damaging the front fascia.

I guess we're SOL then.

Gotta let that hot air out of the engine bay

Are there any aftermarket vented hoods that actually have the vents placed primarily for heat extraction as opposed to putting them wherever looks the nicest?
