 Posted: Wed Jun 21, 2017 11:55 am Post subject: Rear air scoop covers? |
 |
|
| I'm converting my 1969 bay window bus to electric power, and I need to seal the engine bay in order to keep it relatively dry. I've seen a few examples of people making their own rear air scoop covers. Does anyone make and sell scoop covers off the shelf, or are these always custom made? Any thoughts or suggestions appreciated. Cheers |

IMHO. I would think if the bottom of the engine compartment was buttoned up proper. No need to cover scoops.

Interesting. I've got the bottom of the compartment covered pretty well. Not completely water tight, but definitely good enough for my purposes.
It seems like in a heavy rain, water would just pour into these scoops. Is that not the case? Thanks |

Was designed not to soak the engine compartment and would drain away. If you modified the design with the motor you are using. Might be different story.
However, a lot of moisture from the bottom accumulates if not sealed proper. VW wanted to keep road air out and for sure moisture from corroding the engine bay.

The thing about that video and covering the air scoops is... am I wrong or isn't an engine pretty much an air pump? Block off the air and it's going to choke the engine. An electric conversion would be different of course.

I have modified the interior of the engine compartment. There aren't any obvious drain channels they way I have it setup now.
I think I'm going to want to cover /seal the scoops eventually. |

I agree Aeromech, I was thinking the same thing. And OP. I wouldn't be in a hurry to cover. Wait for some rain and see what happens. Aesthetically I think it would look better with scoops exposed (I know not my bus). Maybe you could use some clear durable Lexan 9034 or similar so it keeps the look. I want pictures of the motor set up. Sounds interesting.

Yeah that's good idea. I'll wait and see how it does in the rain first. Thanks for the help everyone |

If you can track down a pair of these, they are the real deal:

If it snows heavily where you live you may want to get a pair of these:
They were sold by the dealer (000 091 232) but you can still find them on eBay for about $40. Made in Germany and they fit 73-79 models.

| You could probably make a baffle that would sit inside the scoop and redirect most of the water, it could channel the water out the bottom louver or pipe it through the floor somehow. |
